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 ...

What if the engine of the future wasn’t just a dream, but a reality? Imagine a power source that combines the raw, exhilarating performance of a two-stroke engine with innovative efficiency, ...

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 ...

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 ...

We may receive a commission on purchases made from links. When thinking about diesel engines, it's easy to associate them with heavy-duty applications. Diesel engines are more durable than gasoline ...

Unlike a Wankel rotary engine, the Avadi eliminates the traditional crankshaft entirely, as the cylinder and piston rotate within the case during its stroke. Everything very much looks and functions ...

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 ...

Whether we're talking about vehicles with two or four wheels, a primary goal of engineers is to wring out as much power from each unit of displacement for every engine they make. This keeps weight ...
