Experimental Research on a Dual-Coil Ignition System of CNG Engine

Abstract:

A dual-coil ignition system was designed in order to improve ignition performance of CNG engine. The change rule of ignition energy was studied in voltage regulator tube string simulated load, the change rule of secondary voltage was studied in spark plug load. Experimental results explain that compared with single-coil ignition, the new ignition system can enhance ignition energy, increase secondary voltage, increase spark duration ,achieve multiple discharge and improve coil energy efficiency under apposite charging time to primary coils and discharging time interval to secondary coils. This system can correct discharge characters according to engine working conditions, which is very useful to CNG engine.
