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 ...

How hard could it to be to build a two-stroke internal combustion engine (ICE) from scratch? This is a challenge that [Camden Bowen] gladly set for himself, while foregoing such obvious wastes of time ...

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 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 ...

Traditional Two-Stroke Engine Issues A traditional two-stroke engine has the piston pushing down after firing, moving past an exhaust port and allowing the exhaust gases to leave the chamber.

Have you ever woken up in the middle of the night worried that you have never, ever changed the oil on your two-stroke lawnmower? Well, you can relax. A two-stroke oil change is like a left-handed ...

Engine power is a product of its overall displacement, but two similarly-sized engines with different bore and stroke characteristics don't perform the same.

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