The ignition coil generates a voltage high enough to ignite a spark between the spark plug electrodes.
The primary and secondary coils are wound around the core. The number of turns of the secondary coil is approximately 100 times that of the primary coil. One end of the primary coil is connected to the igniter and one end of the secondary coil is connected to the spark plug. The other ends of the two coils are connected to the battery.
When the engine is running, current from the battery flows through the igniter to the primary coil based on the ignition timing signal (IGT) output from the engine ECU. As a result, magnetic lines of force are generated around the coil, which contains a magnetic core at the center.
Three elements for a gasoline engine to work properly
Good fuel mixture, high compression pressure, ignition timingCorrect mage and strong spark. The strong spark generated in the ignition system ignites the combustible mixture at the optimum ignition time.
The ignition system generates sparks using the high voltage generated by the ignition coil, igniting the compressed combustible mixture. The combustible mixture is compressed, ignited and burned in the cylinder to produce engine propulsion.
The engine intake system mixes gasoline and air The intake valve opens and the mixture enters the cylinder and the high voltage coil (ignition module). ) transmits high voltage. Piezoelectricity is transmitted to the spark plug through the cylinder wire to ignite the mixture, and the instantaneous high pressure generated in the cylinder causes the piston to move down, causing the crankshaft to rotate, while the other pistons just move up , and this cycle makes the engine move.
Main benefitsntages:
When the motor is running, each moving part acts on another part with a certain force, and high-speed relative movement occurs. With relative motion, the surface of. the part Friction is inevitable and wear is accelerated.
Therefore, in order to reduce wear, reduce friction resistance and extend service life, the engine must have a lubrication system.
