Featuring a series of tubes, the intake manifoldensures that the air coming into the engine is evenly distributed to all the cylinders. This air is used during the first stroke of the combustion process. The intake manifold also helps cool down the cylinders to prevent the engine from overheating.
A crankshaft is a
mechanical component used in a piston engine to convert the reciprocating motion into rotational
motion. The crankshaft is a rotating shaft containing one or more crankpins, that
are driven by the pistons via the connecting rods.
The crankpins are also called rod
