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

Lastly, it has better specific power than a four-stroke engine. Moreover, since it has fewer moving parts, it has lower inertia, meaning it can start and rev faster than a 4T.

Basically, this thing is a mashup of four-stroke and a two-stroke engine designs (here's how an engine works, by the way), that results in two power strokes in three revolutions.(A stroke, as ...

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 ...

Four-stroke outboards like this one are more fuel efficient and produce fewer emissions. Ilya / Adobe Stock. Simpler doesn’t always mean better, though. It’s no coincidence that every modern ...

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.

Most of you reading this probably have at least a basic understanding of how an internal combustion engine works. Today’s four-stroke suck-squish-bang-blow concept was first demonstrated ...

The engine capacity debate is a never-ending topic of discussion in the Paulo Duarte FIM EnduroGP World Championship paddock.

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.

Oil and petrol are miscible. Your 1:50 boat mix is lean in oil. Seagull outboards used 1:10 (smoked a lot and were long-lasting).

Wärtsilä’s 4-stroke engine-based solution for ammonia fuel now delivers higher than ever levels of efficiency and performance.. Following its introduction to the commercial marine sector in ...
