The two-stroke engine is mostly a piece of history today, but there was a time when some of the coolest developments in engine technology were two-cycle engines. Here’s how two-stroke technology rose ...

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 ...

Unit shown in the bottom of the photograph has been removed to show operation of the V-drive which is base of V-four engine.Ring gear shown on lower shaft of top unit is driven by a pinion mounted to ...

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 ...

It's important to keep in mind that the combustion process occurs in a very brief period of time. Due to a variety of conditions that include mixture density, homogeneity, temperature, fuel ...

We love ourselves a good oddball engine, and tiny, scrappy Mazda certainly must be responsible for more such engine concept patents per market-capitalization dollar than any other. We just discovered ...

Conventional wisdom suggests that our faithful internal combustion (IC) engines are heading the way of the buggy whip. The lithium-ion battery has arrived, emissions standards are tightening, and ...

It's been a long time since the automotive world has bothered with the mixing of oil and gas of the two-stroke combustion cycle — but soon, it may come time to rid ourselves of four-stroke engines, if ...
