Formula to save diesel cars revealed

Every day there is more and more talk about the 'disappearance' of diesel cars, while electric cars are developing rapidly.

One of the main reasons for the decline in diesel cars is the toxic substances and gas emissions they cause.

But, the engineers Shelf believe they have found the solution to this problem, by developing a 2.0-litre WV Golf Mk7 GTD that emits 60% less NOx, along with a 4% improvement in fuel consumption and a reduction in C02 compared to a standard car.

"In other words, we have resolved a classic conflict of objectives in diesel engine development," says Jose Avila.

This solution combines a suite of systems that are already available. The first step is to replace Continental's standard PCRs5 injection system, which operates up to 2500 bar, writes IndeksOnline.

Combined with the dynamic valve process, it is possible to perform multiple precise injections per cycle, with a minute amount of fuel injected after combustion.

This only ignites when it reaches the catalyst, speeding up the catalyst warm-up time. This has important implications because the catalyst only starts converting NOx above a certain temperature.

A further reduction in emissions is achieved by using a narrow electrical catalytic converter (EMICAT).

This brings the downstream catalyst up to operating temperature (between 250°C and 400°C) within 30-40 seconds depending on ambient temperature, allowing it to begin converting NOx. Equally important, it maintains the catalyst's operating temperature even in slow traffic, when it would normally idle. /IndeksOnline/
