Everyone is getting fascinated by car driving. Driving is possible because of an engine. An Engine provides mechanical motions to a transmission & Car wheels takes revolutions from a transmission system to run forward.
An engine of a car or vehicle produces mechanical work by using other forms of chemical & heat energies & processes. An Engine runs on different types of fuels like gasoline & diesel mixing with proper amount of air.
An engine type mentioned above is an internal combustion engine in which air-fuel mixture is pressurised and allowed to expand to move the piston up & down. Piston further turns the crankshaft.
Car Engines work on a four stroke combustion cycle. Fuel & air in an appropriate amount is used as an intake charge. Due to this intake charge, there are four strokes are produced Viz. Intake, compression, combustion & exhaust.
Strokes are repeatedly occured in a combustion chamber to produce power. We should know how these combustion cycles are producing mechanical motion. So following explanation provides a detailed information about engine strokes.
Piston is at bottom position for this stroke. In this stroke, Intake valves open & Intake charge comes into the combustion chamber.
Compression of intake charge starts in this stroke. The piston moves up & compresses the air-fuel amount leading the explosion process.
Spark plug ignites in this stroke & explosion of intake charge occurs. There is greater power produced due to explosion which forces the piston Down.
Exhaust valve opens in this stroke to let the exhaust gases release from combustion chamber. Further these gases pass to the catalytic converter & tailpipe for releasing the clean exhaust to atmosphere.
