If you’re shopping for a new fishing boat or an outboard motor to power it, one of the decisions you’ll have to make is between a 2 stroke vs 4 stroke engine ... In other words, a two-stroke engine ...

The problem, as Moore sees it, is everything that happens between the "bangs" of a four-stroke engine cycle. The power stroke sends the piston downward with considerable energy, but then the ...

But [Integza] wanted to see what happens inside a 4 stroke engine, and it wasn’t enough to see it from a transparent cylinder head. No, he wanted to see it in the cylinder itself. Thanks to ...

As described above, a 4 stroke engine only uses the area above the piston to combust air and fuel and expel exhaust. The combustion cycle starts with the piston going down during intake ...

A steam engine goes through four thermodynamic modes in a complete operating cycle known as four-stroke – adiabatic compression, isovolumic heating, adiabatic expansion and isovolumic cooling.

A 4-stroke engine goes through four strokes of the piston to complete the combustion cycle, while a 2-stroke engine goes through only two strokes of the piston to complete the combustion cycle.
