Estimation of the Accumulated Energy in the Hybrid Ignition System

In this paper, we investigate and analyze the possibility of saving energy in the hybrid ignition system. The working model we research here is the four-cylinder hybrid ignition model, which has two separately stages of ignition: the inductance-discharged stage and the capacitor-discharged stage. Results show that the accumulated energy saved in capacitors is sufficient for the capacitor-discharged stage. Primary current, self - induced emf, oscillation frequency are collected in engines via PicoScope 4425 Automotive Oscilloscope and simulated by Matlab to determine the effect of resistance, capacitance and self-inductance on the hybrid ignition system. The experiment data - primary current, self-induced emf, oscillation frequency and dwell time - is also collected in the four-cylinder hybrid ignition model via PicoScope 4425 Automotive Oscilloscope.
