The 1958 DKW 3=6 looked like a modest family saloon, but its engineering was a quiet rebellion against four-stroke orthodoxy.

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 ...

Name a type of terrain, and someone, somewhere, will figure out a way to race on it. From wood-track ovals and countryside rallies to the pure chaos of the Gumball 3000, humans love to pit themselves ...

One of the most significant contributions in the history of propulsion technology came from a 19th-century engineer named Rudolf Diesel. While his idea was patented in the 1890s, it wouldn't be until ...

Have you ever wondered why you need to add oil to your chainsaw’s fuel supply? Or why some dirt bikes have a higher pitched exhaust note than others? We’ve all been burdened with yard work or been ...

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 ...

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 ...

Ahh, two-stroke engines. Many people associate the sound (and smell) of a two-stroke with yard equipment, but for motorcycle fans, it signifies something else entirely – performance. See, before ...

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 ...
