The starting system of an internal combustion (IC) engine is responsible for cranking the engine and starting the combustion process. The primary components of an IC engine starting system are the battery, starter motor, ignition system, and fuel system.
Here is a step-by-step explanation of the working principle of an IC engine starting system:
When the driver turns the ignition key, an electrical signal is sent to the starter motor.
The starter motor receives the electrical signal and begins to turn the engine crankshaft, which in turn rotates the engine's pistons.
As the engine turns over, the fuel system injects fuel into the engine's cylinders, and the ignition system sparks to ignite the fuel-air mixture.
Once the engine fires up, the starter motor disengages from the engine crankshaft and stops rotating.
The engine continues to run on its own power, and the driver can release the ignition key.
The battery is recharged by the engine's alternator, which generates electrical power as the engine runs.
In summary, the starting system of an IC engine is responsible for cranking the engine and starting the combustion process, and it consists of several components that work together to accomplish this task.
