Automobile ignition starting principle

1. The automobile starting system is mainly composed of the starter and starter control circuit.

2. The starter is used to start the engine, it is mainly by the motor part, the transmission mechanism (or engagement mechanism) and the starting switch three parts.

3. Engine starting principle To make the engine transition from a stationary state to a working state, you must use an external force to turn the crankshaft of the engine, so that the cylinder inhalation (or the formation of) combustible mixture and combustion expansion, the work cycle can be carried out automatically. Crankshaft in the external force began to rotate to the engine began to automatically idle the whole process, known as the engine start. There are many ways to start the engine, automobile engines commonly used motor start is to use the electric motor as mechanical power, when the gear on the motor shaft and the engine flywheel peripheral gear ring mesh, the power will be transmitted to the flywheel and the crankshaft, so that it rotates. The electric motor itself in turn uses a battery as an energy source. The vast majority of automobile engines today use electric motors for starting.

4. Composition of the starter The starter is generally composed of three parts: (1) DC series-excited motor, its role is to generate torque. (2) transmission mechanism (or meshing mechanism), its role is: in the engine start, so that the starter drive gear meshed into the flywheel ring, the starter torque to the engine crankshaft; and in the engine start. After the engine is started, the driving gear slips and the flywheel ring is automatically disengaged. (3) control device (i.e. switch). Used to connect and cut off the circuit between the starter and the battery. In some automobiles, it also has the role of accessing and isolating the additional resistance of the ignition coil.

5. The function of the starter The function of the starter is: the use of the starter will be converted to mechanical energy from the battery, and then through the transmission mechanism will be dragged to start the engine.
