The advent of stricter emissions regulations leads to a delay in combustion until after TDC (with a lower cylinder pressure and temperature), although this causes fuel economy to worsen. The result is cleaner combustion with low NO x and soot emissions. The SKYACTIV diesels feature a low compression ratio of 14.0:1 Source: Mazda.

CVRAS provides a single validation standard for any emission technology to meet the standards set out in the government’s Clean Air Zone Framework for England. Data from the three tailpipe emissions tests will be averaged to yield a mean result. The scheme will also provide the backbone of future retrofit funding.

A team from the University of Michigan and Ford’s Research and Advanced Engineering group in Dearborn has studied the effects of ethanol on reducing particulate emissions from a direct injection spark ignition (DISI) engine by comparing neat anhydrous ethanol with a baseline fuel of reference grade gasoline (indolene).
