It looks like GM is working on modernising two-stroke engines by tackling their emissions problem. This could open a whole new chapter for internal combustion. It’s been a while since two-stroke ...

Bore and stroke do far more than define engine size. They help shape airflow, piston speed, torque delivery, and rev ...

Engine power is a product of its overall displacement, but two similarly-sized engines with different bore and stroke ...

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 ...

The rattle, buzz and clatter of a two-stroke engine is unmistakable, but it isn't necessarily good for the planet. That's because A) two-strokes burn oil and B) they are inefficient. Lubricating oil ...
