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 ...

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 ...

Two-stroke engines have steadily fallen out of favor over the last 50 years or so. While they sport great power-to-weight ratios and are often much simpler mechanically than their four-stroke ...

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 ...

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 ...
