Internal combustion engines typically have low efficiency, with modern gasoline engines around 35% and diesel engines ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

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 two ...

Almost all gasoline engines, whether they're efficient-yet-less-refined four-cylinders, high-horsepower V6s, or growly and torque-rich V8s, use much the same process to create power. The "Otto cycle" ...

Generally, combustion engines follow a standard principle of operation founded on the premise that the crankshaft spins clockwise (as seen from the driver’s seat). That’s how the powerplants are ...

This means that the high torque efficiency of the two-stroke engine is kept, while the cleanliness and longevity of the four-stroke engine is gained. A win-win scenario. What’s more, the exhaust ...

You've seen plenty of weird engines on Jalopnik, from Trojan's weird two-stroke, four-cylinder cube with wishbone-shaped connecting rods to the Napier Deltic triangle-18 diesel, but never have you ...

The Beta motorcycle brand expanded into professional Motocross racing in 2021, joining the MXGP series. The company expanded ...

It's been a long time since the automotive world has bothered with the mixing of oil and gas of the two-stroke combustion cycle — but soon, it may come time to rid ourselves of four-stroke engines, if ...

Any oddball engine is clickbait crack for mechanical nerds, and the most compelling ones purport to introduce an entirely new combustion concept. "Not a four-stroke, not a two-stroke, a revolutionary ...
