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

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

DeltaHawk's two-stroke diesel engine sparked the interest of aviation companies large and small around the world.

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 ...

How a German Missile Scientist Revolutionized the Two-Stroke Engine The design has since been iterated upon and improved, but Walter Kaaden’s development started it all.

“The performance, durability and ease of maintenance for two-stroke engines is unbeatable and provides an ideal platform for the future of aviation, manned or unmanned. We are very excited to be ...

Engines using "entry ignition" could be up to 14 percent more efficient than a traditional internal combustion system.

The engine’s two-stroke combustion cycle produces twice as many power strokes per crankshaft revolution as a standard four-stroke engine. In this way, it delivers more power.
