Intake Manifold
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.
Crankshaft
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
bearing journals, and they rotate within the "big end" of the
connecting rods.
Most modern crankshafts are located
in the engine block. They are made from steel or cast iron,
using either a forging, casting or machining process.
