The defining characteristic of a two-stroke engine is to fire (combust) every time the piston is at top dead center. This makes them highly power dense, but also notoriously makes two-stroke engines ...

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

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 ...

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, ...

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 ...
