- A.
Beginning of suction stroke
- B.
End of suction stroke
- C.
Beginning of exhaust stroke
- D.
End of exhaust stroke
Correct Answer
A. Beginning of suction strokeExplanation
In a four-stroke cycle, the minimum temperature inside the engine cylinder occurs at the beginning of the suction stroke. During the suction stroke, the piston moves downward, creating a vacuum that allows the intake valve to open. This allows the fresh air-fuel mixture to enter the cylinder. Since the air-fuel mixture is being drawn into the cylinder from the outside, it is usually cooler than the gases inside the cylinder. Therefore, the temperature inside the cylinder is at its minimum at the beginning of the suction stroke.Rate this question:
