DESCRIPTION
An Air Starting Motor is a component used to start the engine of a heavy-duty truck. Part Number 4099474 denotes a specific model of this motor. As the name suggests, it uses compressed air to turn the engine's crankshaft until it starts running on its own power. This motor is typically used in diesel engines, where the high compression ratios require a significant amount of energy to start up. The air starting motor works by using the compressed air to turn an impeller or rotor inside the motor, which then transmits torque to the engine's flywheel through a drive shaft or coupling. It is an essential part of any heavy-duty truck's starting system and allows for reliable and efficient operation even in extreme weather conditions or at high altitudes.
