What are the main components of an automobile starting system?

Starting an engine refers to the entire process of transitioning the engine from a stationary state to an operational state. The system required to complete this process is called the starting system. Its function is to drive the engine crankshaft to rotate until the engine can continue operating under its own power. Information about the automobile starting system is as follows: 1. The starting system consists of a starter, a solenoid switch (starting relay or solenoid coil), and a starting switch (or start button). 2. The starter mainly comprises an armature assembly, a solenoid switch, a housing assembly, a rear cover (drive end cover), and a front cover (brush end cover). It uses the battery as the starting power source, driven by a DC motor, and provides starting torque to the engine flywheel crankshaft assembly through the transmission mechanism and control mechanism, enabling the engine to enter normal operating conditions.
From my years in the auto repair business, the core components of a car's starting system consist of several parts. The battery is the starting point, providing the initial electrical power; the starter motor is responsible for rotating the engine's flywheel ring gear to initiate startup; the starter relay acts as the intermediary, amplifying current to activate the motor; the ignition switch is like the button the driver presses, controlling the entire process initiation; there are also wires and connectors that link all components together. Common issues include battery aging, which often leads to failure to start in winter, necessitating checks for terminal corrosion every six months. Additionally, burnt relay contacts can also cause startup failure, so regular maintenance is recommended to prevent sudden breakdowns. During maintenance, using a multimeter to test for stable voltage can extend the system's lifespan and reduce headaches.
