What is the function of a push rod in an engine?

To transfer motion from the camshaft to the rocker arms
To regulate fuel injection
To open and close the throttle
To pump oil through the engine

The correct answer is: To transfer motion from the camshaft to the rocker arms

The function of a push rod in an engine is to transfer motion from the camshaft to the rocker arms. This transfer of motion is essential in controlling the opening and closing of the engine's valves. Option B, regulating fuel injection, is usually done by the fuel injection system rather than the push rod. Option C, opening and closing the throttle, is typically controlled by the throttle linkage and not the push rod. Option D, pumping oil through the engine, is the function of the oil pump and not the push rod.
