How does the Mazda Skyactiv-D diesel engine work?

A revolutionary diesel engine, SKYACTIV-D delivers great fuel efficiency without sacrificing clean emissions. With its world-leading compression ratio of 14:1, SKYACTIV-D provides a fuel economy improvement of 20% over conventional diesel engines and meets exhaust emission standards in countries around the world.

What’s the difference between SkyActiv and Mazda 2.2?

The main difference is that the new engine has a reduced compression ratio. It dropped from 16.3 to 14, and this number is pretty low for diesel engine and almost the same as SkyActiv petrol engines have. Lowering the compression ratio to 14 is noticeably dropped the temperature and pressure in the cylinder.

What causes soot to form in Mazda Skyactiv-D?

As a result, the formation of NOx and, due to combustion with insufficient oxygen, the formation of soot are brought about (Fig.1).
