Answer & Solution
Answer: Option
C
Solution:
The push rod is an essential component in an internal combustion engine, especially in overhead valve (OHV) engines. It plays a crucial role in the valve actuation mechanism.
Function of Push Rod:
- The push rod transmits motion from the tappet (or lifter) to the rocker arm.
- It helps in opening and closing the engine valves by transferring the camshaft motion.
- It ensures proper valve timing and smooth engine operation.
Analysis of Options:
- Option A: Valve and valve spring → Incorrect, as the push rod is not directly connected to the valve spring.
- Option B: Valve and rocker ram → Incorrect, because the push rod is positioned between the tappet and rocker arm, not the valve.
- Option C: Tappet and rocker ram → Correct, as the push rod connects the tappet (lifter) to the rocker arm.
- Option D: None of these → Incorrect, as Option C provides the correct answer.
Conclusion: The correct answer is Option C: Tappet and rocker ram, as the push rod transmits motion between these two components in an engine's valve mechanism.
