Every new internal combustion car and truck sold in America today is equipped with a four-stroke engine, as are the vast ...

Every internal combustion engine needs oil for lubrication, but two-stroke engines take their oil regularly along with ...

Since two-stroke engines have fewer moving parts, they are easier to manufacture, and logic would dictate they would be easier to maintain. That couldn't be further from the truth due to friction.

Since two-stroke engines are more polluting, they were banned for most street motorcycles. Still, they are used on lighter applications such as lawnmowers, generators, or go-karts.

In the most basic mechanical terms, a two-stroke engine is simpler than a four-stroke engine. It has fewer moving parts and requires fewer steps to achieve combustion. Key Differences Between a Two- ...

Discover how Alpha-Otto's RevForce engine transforms two-stroke engines with a rotary valve, enhancing efficiency and reducing emissions.

The 250 RX is a long-stroke motor, while the 350 RX is a short-stroke mill. Despite that, the 250 delivers “explosive ...

The Alpha Otto Rev Force features forced induction, rotary exhaust valves and can run on a variety of different fuels.
