When it comes to engine manufacturing, Detroit Diesel stands up there with the best of them. Established in 1938 as a General Motors division, the company primarily focused on manufacturing diesel ...

General Motors may not be building a bike engine, but this two-stroke concept has real potential for motorcycle engineering.

The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

Anyone who appreciates simplicity of design and efficiency of operation has to like small two-stroke-cycle engines that power construction tools such as cut-off saws, rammers and breakers. Producing ...
