Caused by a failure of the distribution board.
The distributor is the transfer station of high and low voltage electricity in the ignition system. It can connect or break the circuit to the ignition coil, then distribute the generated high voltage to each cylinder. . spark plug.
The ignition system is an important part of the gasoline engine. The performance of the ignition system has a significant impact on engine power, fuel consumption and exhaust pollution. Any equipment that can generate an electrical spark between the two electrodes of the spark plug is called the engine's "ignition system." It usually consists of a battery, generator, distributor, ignition coil and spark plug.
When the engine is operating normally, since the temperature of the mixture at the end of compression is close to its auto-inflate temperaturemmation, only 1~5 mJ of spark energy is required. However, when the mixture is too rich or too lean, when the engine is started, idling, or the throttle is abruptly opened, higher spark energy is required. And with the improvement of the requirements of modern engines for economy and purification of exhaust gases, it becomes urgent to increase the spark energy. Therefore, in order to ensure reliable ignition, high-energy electronic ignition systems generally must have a spark energy of 80 to 100 mJ and must produce a spark energy greater than 100 mJ when starting.
The power supply is a battery with a voltage of 12V or 24V. The ignition coil and the circuit breaker jointly generate a high voltage of more than 10,000V. Divided into primary circuit and secondary circuit . The ignition coil is actually a transformer, mainly composedpalment of a primary winding, a secondary winding and an iron core.
The circuit breaker is a switch operated by a cam. The circuit breaker cam is driven by the motor valve cam and rotates at the same speed. That is, for every two revolutions of the crankshaft, the camshaft rotates once to ensure that each cylinder ignites once in turn for two revolutions. crankshaft, the number of edges of the breaker cam is generally equal to the number of cylinders in the engine, the contacts of the breaker are connected in series with the primary winding of the ignition coil to cut or connect the circuit of the primary winding.
