Abstract

With the intention of improving ignition performance of natural gas engine, a dual-coil ignition system was devised according to energy superposition principle. Using Multisim software and experimental apparatus, the variation of secondary voltage along with discharge time interval was studied by taking simulation and experimental methods. The results show that dual-coil ignition system can enhance the secondary voltage, increase spark duration and accomplish multiple discharge under different discharge time interval compared with single-coil ignition system. So the dual-coil ignition system is conducive to reliable ignition for natural gas engine under different working conditions and it provides a way to optimize the ignition system.
