Which of the following lists the stages of the four-stroke engine cycle in the correct order of operation?
a. Intake, compression, power, exhaust
b. Exhaust, power, intake, compression
c. Intake, power, compression, exhaust
d. Power, intake, exhaust, compression

Respuesta :

The answer is (a) Intake, Compression, Power, Exhaust.
The fourth-stroke engine cycle or the commonly known as the four cycle is a type of engine that completes four separate strokes while turning a crankshaft. First is the Intake where the piston begins at TDC. Second is the compression where it begins at BDC and the piston compresses the air-fuel mixture for ignition. Third is combustion where the second revolution of the cycle starts. Last is the exhaust where the piston once again returns to TDC from BDC.
