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

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.
