Like countless other 19th-century inventors, entrepreneurs, and tinkerers, British engineer James Atkinson sought ways to improve on the Otto four-stroke combustion engine, first produced in 1876.

Those are the three pieces of our cycle. So we just pick things we like, and we call it a high-efficiency hybrid cycle," Shkolnik said. The HEHC engine turns out to be pretty adaptable.

Camshafts and crankshafts perform separate functions, but must work together in a well-choreographed sequence for your engine to operate smoothly.

The static total displacement of all six combustion chambers is 0.76 liter (46 cubic inches), but the volume in which combustion occurs at full boost during the 720 degrees of rotation it takes ...

The full system test of the 500-ton-thrust, dual nozzle kerosene-liquid oxygen staged combustion cycle engine took place on Nov. 5, marking a milestone for the rocket engine.

Camshaft legend adds another two strokes to internal combustion cycle As a hot-rodding legend and inductee into the Drag Racing Hall of Fame, 75-year-old Bruce Crower could have sat back and ...

To break it down into basic terms: a two-stroke engine completes a combustion cycle after just one revolution of the crankshaft, while a four-stroke engine requires two complete revolutions to ...

TL;DR: A hypersonic dual-mode ramjet engine is a high-speed air-breathing jet engine capable of operating efficiently at both lower and extremely high Mach speeds by utilizing dual combustion modes.
