The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

We've seen many engine configurations come and go, with some being more noteworthy than others and some being just outrageous. Honda attempted to modify the shapes of the pistons used in its engine, ...

In Two Stroke Spark Ignition engines the thermal efficiency increases with increase in compression ratio. Also, with higher compression ratios the lean burning limit increases because of the reduction ...

Two-stroke? Forced induction? Compression-ignition-capable? That is many unexpected engine technologies combined into a single engine.

Some engines use a spark to ignite their fuel, and others rely on compression. What does all of that mean? And how do the two kinds of engines differ?

The end result was a two-stroke engine that produced up to 200 horsepower per liter, nearly double what was previously possible—the most powerful engine ever at the time.

Two power strokes and two compression strokes per cycle. Generally, the biggest difference between a typical 4-stroke engine and the 6-stroke design is in the cam and valve timing.
