The power amount generated by a 4 stroke engine is in due course limited by piston speed due to material strength. The piston is then forced to downward for the third stroke by the resulting expansion of burning gases. This 4 stroke cycle begins at the top dead center while the piston is at its peak point. 4 stroke ATV exhaust system is definitely easily manufactured in multi-cylinder configurations, thus making it useful in high-output applications.

They are the intake induction Level Indicators Suppliers stroke, compression stroke, power combustion stroke, and exhaust stroke. Engine's power output depends on the ability of the engine to allow large volume flow of both air-fuel mixture and exhaust gas through the particular valve sports usually located in the cylinder head.

This concept is more fuel –efficient and clean burning compared to two stroke cycle engine. Finally, the fourth and last upward stroke evacuates the spent exhaust gases from the cylinder past then open exhaust valve through the exhaust port.

Now, the intake valve closes and the subsequent upward stroke or compression compresses the fuel- air mixture. So how does four cycle engine work? A basic thing you must know is the fact that it is characterized by straight movements alternately, back and forth of a piston inside a cylinder.
