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 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 ...

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 ...

Two-stroke and four-stroke dirt bikes each bring unique strengths to the track and trail. Two-strokes are light, responsive, and agile, while four-strokes deliver smooth torque, stability, and ...

Gearheads and faithful Jalopnik readers already know the basics of an engine's bore and stroke, but for those that might be new here, let's dip our toes in the shallow end. An engine's bore refers to ...

An engine's displacement dictates power output based on the bore and stroke, while compression ratio influences how strong ...

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 ...
