Why are there four? And what is a stroke, anyway? A modern gas engine most commonly uses pistons and a crankshaft to power the wheels of a car or truck. The piston is basically a round thing on a ...

The eccentricity causes the piston stroke to have two different top dead center (TDC) and bottom dead center (BDC) values. The shortest strokes of the six strokes coincide with the intake and ...

It is shown that when the piston finishes its stroke flush with the wall the piston vortex interacts with the primary vortex. Experiments reveal that the piston vortex can have a significant effect on ...

Stroke indicates how many times the piston in an engine travels up and down to complete a full ignition and exhaust cycle. In a two-stroke engine, the piston ignites the fuel in one stroke and ...

We’re introduced to the traditional two-stroke diesel engine as thermally efficient but not smooth-running, and then the gas turbine as smooth but much more inefficient. The free piston engine ...
