1. Electric starter: This is the most common method and involves using an electric motor to crank the engine. The starter motor is connected to the engine's flywheel and draws power from the vehicle's battery. When the ignition key is turned, the starter motor engages with the flywheel and turns the engine over until it starts.
2. Air starter: An air starter uses compressed air to turn the engine over. This method is often used in large diesel engines, such as those found in trucks and buses. The compressed air is stored in a tank and released through a starter valve when the ignition key is turned. The air pressure drives a piston that is connected to the engine's crankshaft, causing the engine to rotate.
3. Hydraulic starter: A hydraulic starter uses hydraulic pressure to turn the engine over. This method is similar to an air starter but uses hydraulic fluid instead of compressed air. The hydraulic fluid is stored in a reservoir and pumped through a hydraulic motor when the ignition key is turned. The hydraulic motor drives a gear that is connected to the engine's flywheel, causing the engine to rotate.
