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 ...

A traditional two-stroke engine has the piston pushing down after firing, moving past an exhaust port and allowing the exhaust gases to leave the chamber. Simultaneously, as the piston travels ...

General Motors may not be building a bike engine, but this two-stroke concept has real potential for motorcycle engineering. General Motors and two-stroke engines aren’t exactly two things you expect ...
