Understanding Diesel Exhaust Fluid and Its Role in Your Vehicle
As someone who uses diesel vehicles, you may have heard of diesel exhaust fluid (DEF) and its role in reducing harmful emissions. But what exactly is a DEF, and why is it important? In this article, the experts at L&T SuFin will guide you through the basics of DEF, its composition, and how it works.
What is Diesel Exhaust Fluid?
Diesel Exhaust Fluid is a solution made from a mixture of deionized water and urea. It is used in diesel engines to reduce harmful emissions. DEF is injected into the exhaust stream of a diesel engine. When added, it reacts with nitrogen oxides (NOx) to form nitrogen and water vapour. This reaction occurs in a catalytic converter, which is fitted into the vehicle's exhaust system.
DEF is a crucial component in reducing harmful emissions from diesel engines and is required by law in most countries. Using diesel exhaust fluid helps diesel engines meet the strict emission standards set by regulatory bodies such as the Environmental Protection Agency (EPA) and the European Union (EU). DEF is easy to use and is available at most gas stations, truck stops, and auto parts stores. It is also affordable and cost-effective, as it helps to increase diesel engines' lifespan and improve fuel efficiency.
Why is DEF Important?
Diesel exhaust fluid is crucial in reducing harmful emissions from diesel engines. DEF is a purified water, and urea solution injected into diesel engines' exhaust streams. It breaks down harmful nitrogen oxides (NOx) into harmless nitrogen and water vapour. The use of DEF helps to reduce the levels of NOx emissions, which are known to contribute to air pollution and respiratory problems.
The Environmental Protection Agency (EPA) requires all diesel vehicles and equipment to meet strict emissions standards, and DEF is an essential part of achieving these standards. Without diesel exhaust fluid, diesel engines would emit harmful pollutants at much higher rates. This would significantly impact the environment and human health.
DEF is also cost-effective, as it can extend the lifespan of a diesel engine by reducing the wear and tear on the engine caused by excessive emissions. Additionally, using DEF can improve fuel efficiency, lowering fuel costs and reducing carbon emissions.
Diesel exhaust fluid is crucial for reducing harmful emissions from diesel engines, protecting the environment, and improving human health. The EPA mandates its use and offers many benefits, including increased engine longevity, fuel efficiency, and cost savings. By using diesel exhaust fluid, we can all play a part in reducing harmful emissions and creating a cleaner, healthier world for future generations.
How Do You Use DEF?
Using diesel exhaust fluid is straightforward. Most diesel vehicles have a DEF tank located near the fuel tank, and you can refill it using DEF fluid available at most auto parts stores. The frequency of refills depends on your vehicle's mileage and usage. On average, a DEF gallon should last 300 to 500 miles.
It is crucial to use the right type of DEF for your vehicle. DEF is classified into two grades: AUS 32 and AUS 40. AUS 32 is the most commonly used type suitable for most diesel vehicles. AUS 40 is a higher-concentration diesel exhaust fluid primarily used in heavy-duty vehicles.
DEF Storage and Handling
Proper storage and handling of diesel exhaust fluid are critical to ensure effectiveness. DEF should be stored in a cool, dry place away from direct sunlight and heat sources. Exposure to sunlight and heat can cause DEF to break down and lose its potency. It is also essential to use a sealed container to prevent contamination.
When handling diesel exhaust fluid, it is essential to avoid spilling or splashing it on your skin or clothing. DEF is non-toxic but can cause skin irritation and should be washed off immediately with soap and water.
Final Verdict
In conclusion, diesel exhaust fluid is crucial in reducing harmful emissions from diesel vehicles. Its use is mandated by government bodies worldwide, and using DEF can also improve your vehicle's performance and fuel efficiency.

All You Need to Know about Ball Bearings in India
Ball bearings are commonly used in construction sites, industrial areas, etc. It is a circular joint that connects the rotating part of a machine to its other parts, mostly the stationary ones.
Ball bearings are an indispensable part of various machinery. So, people may have to buy it more often. However, before buying, one needs to know all details related to it. This article talks about the types of ball bearings, their uses, and their selection criteria.
Types of Ball Bearings in India
Ball bearings are named according to their physical design. Depending on the specific purposes, one can select the type and such types are:
- Deep groove
- Angular contact
- Thrust (single-row and double-row)
- Self-aligning
Besides, there are two other types namely, Y bearings and Thin-section bearings.
Deep Groove Ball Bearings:
The grooves are cut more deeply than some alternatives in deep groove ball bearings. Being fully surrounded, they come with more wall-surface. Against it, they can roll and transfer loads in more diverse directions.
It is suitable for bearing axial loads from both the right and left directions. Also, it helps to bear radial loads. When they carry both types simultaneously, they are called radial-axial bearings.
Angular Contact Ball Bearings:
These ball bearings have asymmetrical grooves in which one groove wall is longer than the other. Its two subcategories include double row and single row.
As their name suggests, single-row ball bearings come with a single row of balls. On the other hand, double-row bearings have two rows of balls separated by a long inner wall.
Thrust Ball Bearings:
In such ball bearings, the grooves do not extend to cover enough portion of the balls' tops and bottoms. Hence, it cannot support heavy radial loads. Moreover, these bearings may collapse if excessive force is exerted.
This category is also of two types- single row and double row. A single-row thrust bearing ball bearing is suitable for applications with axial loads in one direction.
Self-aligning Ball Bearings:
These ball bearings come with two rows of balls which provide two rows of contact points against the races' grooves. Such ball bearings are commonly used when a perfect right angle between the shaft and the bearings is not found. Sometimes, it happens due to installation conditions.
Y-bearings are ball bearings that have an extra-long inner race. They extend like a short pipe out of the bearing's sides.
Thin-section bearings come with thin races, smaller ball sizes and narrower grooves. The decreased width and ball size require less material. Hence, it ensures lower operating costs than usual.
Uses of Ball Bearings:
Ball bearings are used in various applications, particularly in devices with engines or rotation mechanisms. Some examples of such ball bearings are:
Agricultural sector: It is often used in the rotating parts of tractors, ploughs, and other equipment.
Construction: From cranes and excavators to compactors and other machines, ball bearings are used in diverse applications in the construction sector.
Centrifugal pumps: It is also used in the rotating shaft near the pump's engine output and fan input.
Household items: One can see ball bearings in household items like bicycles, food processors, hair dryers, and other tools.
Office spaces: Hard drives, fans, fax machines, etc. - the list is long. Thus, ball bearings are used in many applications in office spaces.
Electric motors and gearboxes: Ball bearings support the rotating output shaft in electrical motors. Also, it provides support to gear shafts and input and output shafts in gearboxes.
How to Select the Right Ball Bearings in 2023
If one goes to select the right ball bearing, there are a few things one needs to keep in mind. First, one must check the machine's official references for ball bearings. It will help to find a bearing recommended by the experts who made the machines.
One must focus on a few essential factors if, however, such references are unavailable. They are:
Expected direction and amount of load:
While selecting a ball bearing, one should learn how much operating load is expected. Also, the buyer should learn about the load's expected direction. The standard inner and outer race bearings can be used for radial loads. And for axial loads, a thrust bearing is the ideal option.
Right inner and outer diameter:
One must ensure that the outer diameter fits well into the machine's housing. And the inner diameter should provide a shrink fit and clench the shaft tightly through it.
Bearing material:
One must choose the material depending on the dynamic loading capacity and operating environment. Everything else remains equal in this matter.
Average Speed:
One can learn at which average speed the bearings will operate by checking the machine's dimensions and production rate.
Sealed or open:
It is another vital factor to look at. One should select a sealed, shielded, or open bearing based on a few things. They are the operating environment, accessibility, and initial cost of the ball bearings.
For environments with heavy debris, one should use sealed or shielded bearings. One can use open bearings for environments with low debris.
Besides these, there are other factors like shaft alignment, the width of the races, and so on.

A Comprehensive Guide to Concrete Admixtures
Want to improve the strength of your concrete structure? Admixtures are the way to go. But which type of admixtures should you use to improve the strength of concrete for your project? This article provides a detailed guide on different types of admixtures that you can use to increase the strength of concrete.
Admixtures: What are they?
Concrete admixtures are chemical compounds added during the mixing process to improve the properties and performance of concrete. They can increase strength and durability, improve workability, reduce permeability, and accelerate or retard setting time. There are many types of concrete admixtures available for different types of requirements. One of the most common applications of admixtures is to improve the strength of concrete structures, making them ideal for small-scale and large-scale projects.
Types of Admixtures Used in Concrete to Enhance Strength
Depending on the type of project, there are five different admixtures that can be used in concrete to increase strength.
1. Pozzolanic Admixtures
When mixed with cement, Pozzolanic admixtures react with calcium hydroxide to form additional compounds that fill in the gaps between cement particles, resulting in denser and more durable concrete with increased compressive strength. This makes pozzolanic admixtures ideal for load-bearing applications and large structures like dams. Fly ash and silica fume are commonly used Pozzolanic admixtures.
2. Superplasticizers
Superplasticizers are used to increase the workability of concrete without having to add additional water. This helps to shape and form the concrete with minimal addition of water, which would otherwise weaken the concrete.
Superplasticizers can be used in a variety of concrete applications, including high-strength concrete, self-consolidating concrete, and shotcrete. They can also be used to reduce the amount of water needed in the concrete mixture, which can improve its strength and durability.
3. Water Reducers
Water reducers are used to reduce the amount of water needed in the concrete mixture. They work by dispersing the cement particles more effectively, which can lead to more compact and dense concrete with increased strength.
Water reducers can be used in a variety of concrete applications, including high-strength concrete, self-consolidating concrete, and shotcrete. They can also be used to reduce the risk of shrinkage and cracking in concrete by reducing the amount of water in the mixture.
4. Accelerators
Accelerators are used to speed up the setting time of concrete. Although these admixtures do not directly affect the strength, they enable the mix to cure properly, thereby improving the strength of the concrete. They work by increasing the rate of chemical reactions in the concrete, which can help it reach its full strength potential more quickly.
Accelerators can be useful in cold weather conditions, allowing the concrete to set quickly and attain its strength. However, they can also lead to increased shrinkage and cracking if used improperly. Therefore, it is advised to use these admixtures only when demanded by the application.
5. Retarders
Retarders are used to slow down the setting time of concrete, which can be useful in hot weather conditions. Rapid drying of concrete can result in cracking which eventually reduces the strength of the concrete.
Retarders reduce the risk of cracking and improve the strength and workability of the concrete. However, they can also lead to reduced early strength development if used improperly.
Although accelerators and retarders do not directly affect the strength of concrete, they improve the curing process of concrete, thereby ensuring the required strength.
Overall, the use of admixtures in concrete can be an effective way to increase its strength and durability, while minimizing the risk of cracking and defects. However, it's important to choose the right admixture for the specific application and to follow the manufacturer's instructions carefully to ensure proper use and optimal results.
Which One Should You Choose for Your Project
The choice of the right admixture to increase the strength of concrete depends on the requirements of your project. If your project requires enhanced strength with excellent resistance to cracking, it is advised to use Pozzolanic admixtures, whereas Superplasticizers and Water reducers are recommended if your project requires high density for good loadbearing capabilities. On the other hand, accelerators are used to improve the strength of the concrete when working in colder regions, and retarders are suitable for warmer regions.
Final Thoughts
Admixtures are excellent additives that can enhance the strength of the concrete. However, it is important to analyze your requirements before selecting the right admixture for your project. L&T-SuFin is the leading marketplace in India that provides a wide variety of admixtures that can be used to increase the strength of concrete for your project.

A Guide to Selecting the Best Admixture for Concrete
Admixtures play an important role in improving the properties of the concrete mix, thereby resulting in superior quality output. However, with so many admixtures available on the market, it is often difficult to select the right one for your project. This article provides a detailed guide on the best admixtures for concrete that are popularly used for construction projects in India.
Admixture and Its Types
Admixtures are chemical compounds that are added to concrete during the mixing process to modify its properties and improve its performance. These materials can be added in small quantities and can have a significant impact on the properties of the finished concrete.
There are many different types of admixtures that can be used in concrete, each with its own set of properties and benefits. Some common types of admixtures include:
- Water-reducing admixtures
- Superplasticizers
- Air-entraining admixtures
- Accelerating admixtures
- Retarding admixtures
- Corrosion Preventing Admixtures
- Bonding Admixtures
Five Best Admixtures for Concrete
Admixtures are used based on the requirement of the project. As a result, there is no single admixture that can prove to be the best for concrete in every project. However, some admixtures are commonly used, depending on the requirement of the project.
1. Best Admixture To Alter the Setting Time
Admixture can be used to alter the setting time of the concrete, i.e., either increase the setting time or decrease it. These admixtures are known as accelerators and retarders. Accelerators are used to speed up the setting time of concrete when working in colder regions. In contrast, retarders are preferable for hotter regions to avoid the quick setting of the concrete, allowing for a longer time to shape and finish the project.
Calcium chloride is one of the most commonly used accelerators, due to its easy availability and low cost. Apart from that, triethanolamine, silica fume, silica gel etc., are some other available accelerators. On the other hand, gypsum, common sugar, and salt are some of the commonly used retarders.
2. Best Admixture to Reduce Water Requirement
The workability of the concrete depends upon its softness, which generally increases with the increase in water content. However, increasing the water content beyond a certain limit can affect the strength and durability of the final project. To resolve this issue, you can add water-reducing admixtures, known as plasticizers. These admixtures are available in three types: standard plasticizers, mid-range plasticizers, and superplasticizers.
While standard plasticizers reduce the water requirement of concrete by 10%, mid-range plasticizers reduce it by 15%. On the other hand, superplasticizers reduce the water requirement by 30%. Therefore, adding plasticizers improves the workability of the concrete while improving its overall strength. Calcium and sodium are two of the commonly used plasticizers.
3. Best Admixture To Impart Waterproofing
Waterproofing admixtures generally consist of elements such as aluminium sulfate, zinc sulfate aluminium chloride, silicates, etc. These elements seal the pores of the concrete preventing the water from penetrating through it, which can cause cracks, corrosion, and weakening of the structure over time.
These admixtures are ideal for various projects such as making a concrete water tank or bathroom, where good waterproofing is of utmost importance. It must be noted that these admixtures also act as accelerators, thereby making it necessary to also add retarding admixtures if a slower setting time is desirable.
4. Best Admixture To Improve Durability
Air-entraining admixtures are used when enhanced durability is desirable in the project. These are relatively new admixtures, which when added to the concrete mixture, form tiny air bubbles which improve the workability of the mixture. Furthermore, the aerated mixture results in a lightweight structure with an improved modulus of elasticity, thereby improving the durability of the structure in freezing and thawing conditions. Some of the commonly used air-entering admixtures consist of Teepol, darex, vinsol resin, etc.
5. Best Admixture To Inhabit Corrosion
Corrosion-inhibiting admixtures (CIAs) are used in concrete to reduce the rate of corrosion of steel reinforcement. There are different types of CIAs available in the market, and the selection of the best one depends on various factors such as the severity of the corrosive environment, the type of reinforcement used, and the required service life of the concrete structure.
Calcium nitrite and Calcium nitrate are two of the most commonly used corrosion-inhibiting admixtures. While calcium nitrite is suitable for projects located in an alkaline environment, such as coastal regions, calcium nitrate is suitable for acidic environments.
Apart from these, there are various other types of admixtures that can be used based on your requirement. You can also mix multiple admixtures to impart the desired properties and improve the overall quality of the project.
Final Thoughts
Selecting the best admixture primarily depends on your project's requirements. Therefore, it is important to analyze your requirement and select the right admixtures that impart the required properties to the concrete mix. You can also select multiple admixtures to get the best results. L&T-SuFin is the leading marketplace in India that provides a wide range of admixtures to choose from. They provide detailed specifications of each product to help you select the right one for your project.
AAC Blocks Vs Clay Bricks - What's the Difference?
Autoclaved Aerated Concrete blocks, abbreviated AAC blocks, are a type of masonry block that comprises a combination of lime, cement, water, quartz sand, and aluminum powder. These bricks are cured in a high-pressure chamber.
Like ordinary red bricks, also known as Clay Bricks, they too are used in the construction of walls, floors, and roofs and offer a host of benefits, both to builders and homeowners.
So, how do the two kinds of bricks differ from each other? In this article, we will understand the difference between ordinary red bricks and AAC blocks accounting for several parameters like Compressive Strength, Durability, Utility and Performance, Workability, and Sustainability.
Tabular Comparison Between Red Bricks and AAC Blocks
Refer to the table below for a quick and short comparison between red bricks and AAC blocks.
| Parameter/Property | Red Bricks | AAC Blocks |
| Compressive Strength | 2.5 to 3.5N/mm2 | Higher - 3 to 4.5N/mm2 |
| Durability | Less Durable | More durable due to uniform structure. |
| Utility/Performance | Heavy and Bulky | Thinner, Lightweight and so easy to use. |
| Workability | More labor costs are involved due to slower construction | Faster construction |
| Eco-Friendliness | Not eco-friendly as it uses topsoil. | Eco-friendly in nature as it utilizes leftover like flash. |
Comparing AAC Blocks with Red Bricks
Compressive Strength
Since AAC blocks are manufactured in specialised factories or high-pressure chambers known as claves, the material offers higher compressive strength than ordinary bricks.
AAC blocks provide 3 to 4.5N/mm2 of compressive strength, whereas for Reb Bricks, the value is lower and ranges from 2.5 to 3.5N/mm2.
Durability
When it comes it AAC blocks, they have a more uniform structure in comparison to red bricks, which makes the former more durable in nature, which in turn gives more strength to the entire structure. Rid Bricks are brittle which results in heavy wastage during construction.
Plus there are fewer repairs and maintenance involved when it comes to buildings made up of AAC which means builders, as well as developers, can increase the lifespan of the establishment/buildings with AAC.
Utility and Performance
Utility and performance-wise, AAC blocks offer enormous benefits compared to red or clay bricks.
AAC blocks are lightweight means they are easy to carry/use and are helpful especially for high-construction projects. They are also thinner offering more tensile strength which increases the overall carpet area of a project, which makes them effective especially for smaller area projects.
What's more? AAC blocks are fire resistant offering fire resistance for up to 4 hours, offer better sound insulation of about 42 dB, and have better thermal insulation properties resulting in (25-30)% heating-ventilation costs.
Besides, the AAC blocks are easy to store as they don't absorb much water compared to red bricks. In fact, they absorb a maximum of 10% water by weight and they are earthquake and pet resistant as well.
Workability
Workability implies how easy to handle the ACC blocks are and how easy it's to construct projects with them.
Since AAC is lighter than red bricks for the same volume and has better tensile strength, the material offers superior workability across all kinds of construction projects plus it also requires less labor which reduces labor costs.
Furthermore, the number of joints is less when using AAC blocks as a single AAC block is almost equal to those 6 traditional red bricks. What this means is that the construction will be now faster and less mortar will now be required.
Eco-Friendliness
The final factor to consider AAC blocks over red bricks is the eco-friendliness that the AAC blocks offer.
The Red Bricks are not as eco-friendly as Autoclaved Aerated Concrete Blocks. They're made up of using topsoil, the removal of which causes soil erosion. You might be surprised to know that a single square foot of red brick walling consumes approximately 25kg of topsoil thereby negatively affecting the environment!
AAC blocks, on the other hand, have fly ash as one of their ingredients. Flyash is a waste by-product of the thermal power plant and is usually non-toxic in nature. And the manufacturing of AAC blocks also doesn't release any significant pollutants into the atmosphere.
Conclusion
Compared to traditional red bricks, the newer and innovative AAC blocks have many advantages to offer in all respects - Compressive Strength, Durability, Utility and Performance, Workability, and Sustainability.
One may argue taking the price is a negative factor for AAC blocks, as the cost of AAC is slightly higher than its counterpart, red bricks. But considering the long-term scenario, the positives of AAC outweigh its negatives, making it a perfect choice for construction projects.

More DC Overloading Options:
With this advanced feature, inverters are now capable of handling more loads. And one can use such high-capacity modern power inverters for multiple purposes since they work efficiently without breaking down.
Flexible MPPT Channels:
MPPT, or Maximum Power Point Tracker, affects a machine's stability. Moreover, it impacts efficiency. Modern power inverters now have flexible MPPT channels making them more stable and effective than ever. Smart inverters are expected to come with more flexibility in these tracker channels.
Fuse-less or In-line fuse options:
Unlike traditional variations, smart inverters come with in-line fuse options. Or, sometimes, even with no fuses. In-line fuse holders are wire-mounted holders and are capable of connecting anywhere along a circuit. Thus, it protects a specific line or lines.
Wireless Communication Systems:
Wireless communication means transferring data and voice without any support from cables or wires. Smart inverters often allow two-way communications with modern utility control centres. Additionally. they provide effective wireless communication systems.
Mobile-friendly Applications:
Mobile-friendly apps are a new-age way to manage inverters. One can control smart inverters through one's phone. Thus, there's no stress about managing the inverter when you're away from it!
All such technologies reduce clipping losses. Also, they provide more generation in kWh than the regular PCUs.
Latest Types of Power inverters in 2023
New trends in inverter technology bring convenience to daily life and industrial operations. With it, experts have introduced various types of customised inverters for specific uses.
Smart Inverters:
Due to the rise of DER or Distributed Energy Resources, the grid has multiple complex issues. To solve these problems, smart inverters are coming into the limelight as they can function autonomously.
Hence, they strongly impact residential sectors and the national power grid. The traditional grid requires regular maintenance. But, smart inverters offer more flexibility and efficiency.
In the near future, arc-fault circuit interrupters may be introduced in smart inverters that can trigger an alarm and disconnect the circuit from the inverter in a second making them ideal for rooftop solar projects because they have multiple troubling arcs.
Micro Inverters:
Micro inverters are now a popular choice for residential and commercial purposes. While regular inverters connect to many panels or solar modules, micro inverters can convert DC into AC through a single module. Additional benefits include low shading, debris, snow lines, etc.
However, even though the initial costs of installing these inverters can be slightly higher than that of central inverters, deploying panels with in-built microinverters can solve this problem to some extent.
Battery-based inverters:
Solar installations need efficient storage systems. Hence, the need for battery-based inverters is growing. Such inverters can convert DC into AC besides providing backup power during a grid outage. It requires a battery bank and one can use it in both grid-connected and off-grid systems.
Final Words:
Modern inverters are easier to use and safer than traditional ones. Also, they are more efficient than conventional ones. Technology has indeed solved many problems with them. However, even advanced technology cannot come to the rescue if you do not buy a high-quality power inverter. So, it is wise to trust a reputed source like L&T-SuFin, a leading online platform for industrial products.

Types of Inverters
High-Capacity Inverters
A high-capacity inverter should be considered if you're looking for an inverter with a high power requirement. These inverters can withstand the heavy loads of several powered devices or appliances in offices.
These inverters are ideal for homes with over four to five air conditioners, at least three TVs, refrigerators, and other kitchen appliances. Similarly, offices with over thirty or more computers and central air conditioning also need high-capacity inverters.
Connected Inverter
The connected inverters for your homes and small offices will be connected through a network, letting you monitor and operate gadgets from a distance. In contrast to conventional inverters, connected inverters may deliver thorough diagnostics and monitoring in addition to automatic firmware and software updates.
Homes with less than four devices and devices with a little complication can use these inverters. They are suitable for small offices with minimum power backup requirements.
Standard Inverter
A standard inverter is perfect for households with less appliances. The best part about standard inverters is that they are simple and easy to install and operate. They are not suitable for offices.
As they cannot meet high power requirements with a few systems working. They are not suitable for the functioning of refrigerators and ACs at homes. However, they are ideal for households with two fans and few lights.
Premium Inverter
Premium Inverters will assure you of functioning, and you can be confident that your appliances are operating effectively and that you always know how much power you have left. They are best suited for commercial purposes due to their high power capacity.
While some sophisticated homes also use these inverters but can be used if there is high power need. These devices display backup, inverter load %, and real-time battery charging percentage.
Things to Consider while Buying Home Inverters In India 2023
1. Calculation of Power Requirements
Make a list of the appliances you want to use with an inverter. And decide the power you would need in an emergency. Power will be calculated according to the devices you use and the power it consumes based on the formula. The sum of the power will be calculated.
- For example, a single TV, eight bulbs, two fans, one decoder, and one laptop, a 1.0kVA inverter will be suitable.
- Similarly, for a Light load, 300W, 3 Standing fans of 70W, 2 LCD TVs, 1 Home Theatre Music System, and 1 Juice extractor, a standard inverter of 1.5KVA is ideal.
