An Analysis of Effect to Autoignition at Various Ignition Timing by Using Spectoroscopic Measurement
Details
This study attempted to elucidate combustion conditions in a progression from normal combustion to knocking by analyzing the light emission intensity that occurred during this transition. With the aim of understanding the combustion states involved, the light emission intensity was measured at two positions-the center zone and the end zone of the combustion chamber. Light emission spectroscopy was applied to examine preflame reactions that are observed prior to autoignition in the combustion process of hydrocarbon fuels.This experiment reports on the result of the light emission behavior at various ignition timings.
