Actuators receive signals from the powertrain control module and carry out adjustments needed based on the data the PCM received from the sensors.
The battery supplies the power necessary to start the engine when the ignition switch is is turned on.
The crankshaft converts the reciprocating motion of the piston into the rotational motion that's used to power the vehicle and its components.
