Ignition Circuit for Natural Gas Ignition System
2007 5th Student Conference on Research and Development, 2007This paper presents the development of the high- voltage ignition circuit for coil-on plug ignition system of the natural gas engine. The main specification of the circuit is the modelling and optimization of the ignition power-switching device at the primary side of the circuit, which is important to provide high switching speed to turn-on and off the

An Intelligent Ignition System
IEEE Industry Applications Magazine, 1997A review of the history of electrical resistance igniters (ERI) applications shows that it is the preferred ignition source for gas appliances with only one shortcoming-the ignitors can be easily fractured or broken if not handled carefully. Since this problem was recognized from the beginning, an improved-strength ignitor has been diligently sought ...
