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 ...

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, ...

Humans have been showing and telling each other stories since the beginning. The methods may have changed, but the basic drive to communicate what we've learned to our fellow humans remains. Hence, ...

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 ...

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 ...
