Where is the crankshaft located?

The crankshaft is located in the engine block of an internal combustion engine. It is a rotating shaft that converts the reciprocating motion of the pistons into rotational motion. The crankshaft is connected to the pistons by connecting rods, which are attached to the crankshaft by bearings. The crankshaft also drives the camshaft, which controls the timing of the engine's valves.
