Tata Motors Engineering Research Centre (ERC) has developed a new 3.0-litre, four-cylinder common-rail diesel engine. This engine was designed with emphasis on weight reduction, compliance with emission norms and better fuel efficiency according to the source.
It seems Tata may fit the exhaust gas recirculation (EGR) system as the air intake manifolds are designed to for mounting it. The EGR will reduce the emission levels and also help in better efficiency. However, the engine is still a prototype and the company is yet to take a decision on its application and commercialisation process.
Thie new engine might replace the current 3.0-litre engine that Tata uses in its vehicles when it goes into production. The existing 3.0-litre engine powers the pickup truck range, the Sumo Gold and 407 light trucks.
This engine is very important to Tata as it finds its place in the commercial range as well as in a few passenger vehicles. This could also be an indication that we might see in-house developed engines for the complete range of passenger vehicles from Tata.
