Low-Cost Retrofit Could Help Older Diesel Trucks and Buses<\/strong><\/p>\n\n\n\n

The government is preparing to allow older diesel trucks and buses to use a low-cost retrofit emission-control device (RECD)<\/strong> developed from an innovation at IIT Delhi, potentially offering a cheaper way to reduce pollution from ageing commercial vehicles.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Union Road Transport and Highways Minister Nitin Gadkari<\/strong> said the technology has completed testing and could be used on BS-III, BS-IV and older diesel vehicles. The device is expected to cost around \u20b94,000\u2013\u20b95,000<\/strong>.<\/p>\n\n\n\n

Up to 90% Reduction in Particulate Matter<\/strong><\/p>\n\n\n\n

According to details shared by the minister, the RECD can reduce particulate matter emissions by up to 90%<\/strong> and nitrogen oxide emissions by around 60%<\/strong>.<\/p>\n\n\n\n

The technology is intended to bring the emissions performance of older diesel vehicles closer to the stricter BS-VI<\/strong> standard without requiring owners to immediately replace the entire vehicle.<\/p>\n\n\n\n

Similar emission-control technology is already used for diesel generator sets.<\/p>\n\n\n\n

How the Retrofit Device Works<\/strong><\/p>\n\n\n\n

An RECD is fitted to a vehicle’s exhaust system and treats the exhaust before pollutants are released into the atmosphere.<\/p>\n\n\n\n

In simple terms, the device acts as an additional pollution-control layer for an existing diesel engine. It is particularly aimed at older vehicles whose engines were designed to meet emission standards that predate BS-VI.<\/p>\n\n\n\n

The technology therefore provides a potential middle ground between continuing to operate a highly polluting vehicle and purchasing a new BS-VI-compliant truck or bus.<\/p>\n\n\n\n

Government Preparing New Standards<\/strong><\/p>\n\n\n\n

The Ministry of Road Transport and Highways is preparing to notify Automotive Industry Standard 228 (AIS-228)<\/strong> for the technology.<\/p>\n\n\n\n

The standard is expected to specify the technical and performance requirements that retrofit emission-control devices must meet before they can be commercially fitted to vehicles.<\/p>\n\n\n\n

This regulatory framework will be important because retrofit devices need to deliver consistent emission reductions across different vehicle models and operating conditions.<\/p>\n\n\n\n

A Complement to Vehicle Scrappage<\/strong><\/p>\n\n\n\n

The government does not intend the retrofit programme to replace its existing vehicle-replacement and scrappage initiatives.<\/p>\n\n\n\n

Instead, the technology is being positioned as a complementary measure for older heavy vehicles that continue to operate on Indian roads.<\/p>\n\n\n\n

The government has already been pursuing schemes aimed at replacing ageing, highly polluting trucks and buses with BS-VI-compliant or electric vehicles.<\/p>\n\n\n\n

For owners who cannot immediately replace a vehicle, a \u20b94,000\u2013\u20b95,000 retrofit could offer a considerably less expensive way to reduce emissions.<\/p>\n\n\n\n

Potential Impact on India’s Air Pollution<\/strong><\/p>\n\n\n\n

Older diesel commercial vehicles are an important target for emission-control measures because they can remain in operation for many years.<\/p>\n\n\n\n

If the retrofit technology performs as claimed and is deployed at scale, it could reduce particulate and nitrogen oxide emissions from a large existing fleet without waiting for every older vehicle to be scrapped.<\/p>\n\n\n\n

However, the actual impact will depend on certification, installation quality, maintenance and how effectively the devices perform across different vehicle types.<\/p>\n\n\n\n

Summary:<\/strong> The government plans to allow older BS-III, BS-IV and other diesel trucks and buses<\/strong> to use an IIT Delhi-linked RECD costing around \u20b94,000\u2013\u20b95,000<\/strong>. The device could reduce particulate matter emissions by up to 90%<\/strong> and nitrogen oxides by around 60%<\/strong>, bringing older vehicles closer to BS-VI emission performance while complementing India’s vehicle-scrappage efforts.<\/p>\n","protected":false},"excerpt":{"rendered":"
