The _____ make(s) sure the valves are sealed during the compression and power strokes.

a) Camshaft
b) Crankshaft
c) Piston rings
d) Rocker arm

Answer :

Final answer:

Piston rings ensure the valves are sealed during the compression and power strokes by preventing gas leakage, maintaining engine efficiency. The correct answer is option c).

Explanation:

The question addresses which part of an internal combustion engine ensures the valves are sealed during the compression and power strokes. The correct answer is c) Piston rings. Piston rings play a crucial role in the proper functioning of an engine by creating a sealing barrier that prevents the combustion gases from leaking into the oil sump.

During the power stroke and ensures that the air-fuel mixture does not escape during the compression stroke. This sealing capability of the piston rings is essential for maintaining the efficiency and power output of the engine. While the camshaft controls the opening and closing of the valves, and the crankshaft converts the reciprocating motion of the pistons into rotational motion.

It is the piston rings that assure the compression integrity of the engine. The rocker arm is a part of the valve actuation mechanism that converts the camshaft's rotational motion into the linear motion needed to open and close the valves but does not directly contribute to sealing during compression and power strokes.
