Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

Compression in a diesel engine is essential for effective and efficient performance. And when compression is lacking, damage can result. That is why it’s imperative to know whether your engine’s ...

Today's low-octane unleaded gas mandates a compression ratio reduction for '60s supercars. The easiest way to lower compression is usually to swap on late-model heads; not only do their larger ...

This paper describes the fundamental principles of operation of a mixture injection system now called the Compression Wave Injection system (CWI). The system has been initially designed for use in ...

Because diesel vehicles do not use spark plugs, they must rely on higher compression ratios to ignite the diesel fuel without ...
