Can an Electric Motor Start an Engine?

[PeytonLee]

An engine relies on an electric motor to start. Engine Starting Principle: A DC motor generates electromagnetic torque, meaning it is responsible for the rotational work. The transmission mechanism engages the starter drive gear with the flywheel ring gear, transferring the torque from the DC motor to the engine flywheel. This drives the engine crankshaft to rotate, initiating the working cycle of the engine components until the engine starts. After the engine starts, the starter automatically disengages from the ring gear. The electromagnetic switch is responsible for connecting and disconnecting the circuit between the DC motor and the battery. Precautions for Using a Car Engine: Avoid driving in neutral; pay attention to observations during regular vehicle use. For vehicles equipped with a turbocharger, do not shut off the engine immediately after high-speed driving or climbing a slope. Let it idle for 10 minutes before turning it off. If brake fluid is contaminated with water or impurities, or if sediment is found, it should be replaced or carefully filtered promptly. Otherwise, it may lead to insufficient braking pressure, affecting braking performance.
