The ignition system provides a properly timed spark to burn the air/fuel mixture for the power stroke of the four-stroke cycle. An eight-cylinder engine at 6000 rpm needs 400 sparks a second!

the four-stroke engine’s camshaft. This allows it to distribute spark at the plugs in time with each piston approaching top dead center of its compression stroke. Ignition points were originally ...

While it's possible for either engine type to be either a four-stroke or two-stroke, it's more common to see spark-ignition engines stick to the four-stroke design, while compression-ignition ...

Higher rpm and higher engine loads require HCCI engines to revert to spark ignition, an unpredictable ... blow” of the four-stroke gasoline engine’s Otto combustion cycle, a diesel’s ...

The function of the ignition cycle is to fire the spark plugs at the correct time ... All Corvette engines are four-stroke engines. The four strokes consist of intake stroke, compression stroke ...

So, what is ignition timing? If you’re familiar with the four-stroke engine cycle, you know that ignition comes from spark plugs. The plug fires once the piston reaches the top dead center ...

and combustion (ignition of the compressed gases by a spark) phases. The difference between a two-stroke and a four-stroke engine is how fast the engine combustion cycle occurs, according to the ...
