Nitin Gadkari Backs IIT Delhi Tech to Cut Old Diesel Vehicle Pollution by 90%

A Huge Step for Clean Air in India

Air pollution is a major problem in many Indian cities. Old diesel trucks, buses, and cars are some of the biggest sources of this pollution. To solve this, Union Road Transport and Highways Minister Nitin Gadkari has announced an exciting new plan. The government will soon allow older diesel vehicles to use a special device developed by the Indian Institute of Technology Delhi (IIT Delhi). This simple device can cut down harmful emissions by up to 90%.

This new technology is a big win for both the environment and the economy. Instead of forcing owners to scrap their old vehicles, they can now upgrade them. This makes cleaning up the air much more affordable for everyone.

What is this Retrofit Device and How Does It Work?

The device is called a Retrofit Emission-Control Device, or RECD. In simple terms, it works like a giant air purifier for a vehicle's exhaust pipe. When a diesel engine runs, it releases dirty smoke filled with dangerous particles. The RECD catches these pollutants before they escape into the air.

The science behind it is highly effective. According to details shared by the minister, the RECD can reduce particulate matter emissions by up to 90%. It also cuts down nitrogen oxide emissions by around 60%. Dirty exhaust goes into the device, and much cleaner air comes out on the other side. This technology has already been used to clean up diesel generators, and now it is ready for the road.

An Affordable Option for Truck and Bus Owners

Buying a brand-new, eco-friendly vehicle is very expensive. For many small business owners and truck drivers, it is simply not possible. This is where the IIT Delhi invention becomes a game-changer. The retrofit device is expected to cost only between Rs 4,000 and Rs 5,000. This is a very small price to pay compared to buying a new vehicle.

By installing this cheap device, older vehicles with BS-III and BS-IV engines can perform almost as cleanly as modern BS-VI vehicles. This allows old trucks to keep running safely without damaging the health of people living in busy cities.

Supporting India's Growing Infrastructure

India is rapidly expanding its roads and highways to improve travel and trade. For example, local authorities are continuously working to improve road safety and flow, like when the NHAI opened the relaid service lane on the Chennai-Bengaluru highway in Vellore. As we build better roads, we also need to make sure that the vehicles using them do not harm our health. Combining better roads with cleaner engines is the best way forward.

While Indian colleges like IIT Delhi are focusing on creating these green technologies, other parts of the education sector are also seeing big updates. For instance, in international schooling news, the CBSE cancels Middle East board exams for 2026. These changes show how institutions everywhere are adapting to new challenges.

There’s more to life than simply increasing its speed.

Why Reducing Particulate Matter and Nitrogen Oxides Matters

To understand why this invention is so important, we must look at the health effects of air pollution. Diesel exhaust contains very tiny particles called particulate matter, or PM. These particles are so small that they can easily enter our lungs and even our bloodstream when we breathe. Over time, breathing in this dirty air can cause serious health issues, such as asthma, heart diseases, and breathing difficulties. By cutting these particles by 90%, the new device will directly protect millions of citizens from these dangers.

Nitrogen oxides are another dangerous gas released by older diesel engines. They contribute to the thick smog that covers many Indian cities during the winter months. Smog reduces visibility on highways, making driving highly dangerous. Reducing these gases by 60% will help clear the air, improve highway safety, and make our cities much more livable.

New Government Rules on the Way

To make sure these devices are safe and work correctly, the government is preparing new rules. The Ministry of Road Transport and Highways is going to notify a new standard called Automotive Industry Standard 228 (AIS-228). This standard will set the technical rules and performance levels that every retrofit device must meet.

Nitin Gadkari announced this exciting update at an event organized by the Society of Indian Automobile Manufacturers (SIAM). He explained that the technology has passed its testing phase successfully. The government will not stop its vehicle scrapping program, but this new device will act as a helpful extra option to clean up our air faster.

A Balanced Approach to Environmental Protection

Many environmental policies in the past have forced people to make quick, expensive changes. For example, banning old vehicles completely can hurt small businesses that rely on transport. Nitin Gadkari's support for this IIT Delhi technology shows a much more balanced approach. It allows the government to meet its climate goals while supporting the economic needs of everyday citizens. It shows that green technology can be cheap and easy to use.

A Greener Future for India

This project is a perfect example of how local innovation can solve massive real-world problems. By using smart engineering from IIT Delhi, India can protect the environment without hurting the livelihoods of transport workers. It proves that we do not always need expensive solutions to make a big difference. With the new AIS-228 standards coming soon, we can expect to see cleaner, healthier air on Indian roads in the near future.
