Before we can dive into how the 2-stroke completes its cycle, we need to eliminate a few parts that 4-stroke engines rely on. 2-stroke engines don’t have a camshaft, nor do they have valves, as ...

Porsche was issued a patent for its six-stroke combustion engine on October 22, 2024. The company describes the new engine as having a "working cycle" of three complete crankshaft revolutions with ...

In a 4 stroke engine, air and fuel (and the combustion of said air and fuel) contact the cylinder only. All of the other metal parts in a 4 stroke are contained separately and are continuously ...

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- ...

Four-stroke engines are heavier ... This can be a result of worn out spark plugs, faulty ignition system components such as ignition coils, faulty oxygen sensors or at worst, leaking fuel injectors.

After all, the two-stroke has more power potential in that it creates a power stroke during every crankshaft revolution, and it does so with fewer moving engine parts than the four-stroke.
