Hit-And-Miss engines date back to a time when the design of the internal combustion engine was still very much a work in ...

A four-stroke engine uses four motions of a piston to complete one cycle of combustion. The first stroke of a cycle is the intake. The piston moves down to BDC, making space in the cylinder for ...

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 ...

Codenamed C175-20, the water-cooled, four-stroke, quad-turbo, 20-cylinder diesel engine has a displacement of 105,8 liters (6,456 ci), and, as you can imagine, it's larger than most passenger cars.

How to make an internal combustion engine turn the other way around is a question no one asked, ... the Russians made a four-stroke, four-cylinder Soviet-built engine to spin in reverse.

Now a panicked auto industry is reaching for the e-brake. The internal combustion engine is firmly back on the agenda of product planners and corporate strategists as they plot a path beyond 2030.

Don't write off the internal combustion quite yet. GM said it is investing $918 million in four U.S. plants with most of the money going towards new internal combustion engine production.

Compared to the four-stroke engine that produces one power stroke per two revolutions at 3,000 rpm, the four-stroke has 1,500 power strokes while the six-stroke would have 2,000.

Unlike a four-stroke engine, which musters a single power stroke for every two revolutions of the crankshaft, Porsche's six-stroke affords two power strokes for every three turns of the crank.

Internal combustion engines are far from over: 'There was a bit of hype' around EVs, industry watchers say "Gearheads are realizing the experience is such an important part of the car." ...
