Question

question 3: auto and shop information which is the correct sequence in a four-cycle internal-combustion engine? a: intake, compression, power, rest b: reduction, power, compression, exhaust c: intake, compression, power, exhaust d: exhaust, compression, intake, power

Explanation:

In a four - cycle internal - combustion engine, the correct sequence of the four strokes is intake (where the air - fuel mixture is drawn into the cylinder), compression (the mixture is compressed), power (the compressed mixture is ignited to produce power), and exhaust (the burnt gases are expelled from the cylinder). Option A has “rest” which is incorrect. Option B has “reduction” which is not a stroke in the four - cycle engine. Option D has the wrong order as exhaust should be the last stroke and intake the first. So the correct option is C.

Answer:

C. Intake, compression, power, exhaust
