Single ignition
The individual ignition method is that each cylinder is assigned an ignition coil, and the ignition coil is directly installed on the top of the spark plug, which also eliminates the high-voltage line. This ignition method achieves precise ignition through camshaft sensors or by monitoring cylinder compression. It is suitable for engines with any number of cylinders, especially for engines with 4 valves per cylinder. Because the spark plug ignition coil assembly can be installed in the middle of the double overhead camshaft (DOHC), the clearance space is fully utilized. Due to the elimination of the distributor and high-voltage lines, the loss of energy conduction and leakage is extremely small, and there is no mechanical wear. Moreover, the ignition coils and spark plugs of each cylinder are assembled together and wrapped with external metal, which greatly reduces electromagnetic interference and ensures the normal operation of the engine electronic control system.
