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 ...

The engine is possibly the greatest invention in the history of mankind. Generally speaking, engines are machines that convert one form of energy into mechanical energy and have revolutionized all ...

Traditional Two-Stroke Engine Issues 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.

Unless you're really into dirt bikes, you probably haven't touched a two-stroke engine in decades — if you ever have. These mechanically simple motors combine the four strokes we all know and love ...

An engine's displacement dictates power output based on the bore and stroke, while compression ratio influences how strong ...

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 ...

Two-stroke engines used to be ubiquitous in dirt bike racing, thanks to their lightweight construction and horsepower. Packed in a dirt bike frame, they make a motorcycle playful in the corners and ...

The rattle, buzz and clatter of a two-stroke engine is unmistakable, but it isn't necessarily good for the planet. That's because A) two-strokes burn oil and B) they are inefficient. Lubricating oil ...
