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 ...

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 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 ...

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 ...

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, ...

Even as EVs begin to encroach on ICE cars, the development of fuel-burning engines hasn't stopped. With almost 150 years of development in the Otto cycle internal combustion engine, you may think ...
