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 ...

First and foremost, 2-stroke and 4-stroke are terms that refer to the length of the engine cycle. To better understand what these terms mean, we need to start by clearing your mind. Get rid of ...

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.
