Engine Components Flashcards

The valve cover, which is sometimes called a rocker cover, is an important component of the engine. It keeps oil inside the engine and dust/ debris out.

Engine valves control the flow of air and fuel into the combustion chamber and allow exhaust gases to exit, ensuring efficient engine operation.

A rocker arm is a pivoting lever that helps in opening and closing the engine’s intake and exhaust valves.

A pushrod is a metal tube that transmits the reciprocating motion of a valve lifter to the valve. It sits on the valve lifter and rises into the rocker arm.

A lifter, also known as a valve lifter or tappet, is a small cylindrical component in your car’s engine. Lifters bridge the camshaft lobes and the rocker arms

Camshafts control valve timing through their precisely engineered lobe profiles and synchronization with the crankshaft

The primary role of the crankshaft is to transform the up-and-down (reciprocating) motion of the pistons into rotational motion.

A piston is defined as a cylindrical component that performs reciprocating or linear motion in a pressure-tight tube or cylinder.

A connecting rod is the crucial link between your engine’s pistons and crankshaft, transferring the explosive force of combustion into the rotational motion that powers your vehicle.

A main bearing is a bearing in a piston engine which holds the crankshaft in place and allows it to rotate within the engine block.
