Abstract

The ion current signal in Homogenous Charge Compression Ignition (HCCI) engines was studied to show that a measurable ion current exists even in the very lean combustion in an HCCI engine. Numerical models using detailed chemical kinetics for propane combustion supported the experimental findings. The intake mixing temperature and the applied bias voltage on the ion signal were studied through a series of experiments. An inexpensive ion sensor might replace the expensive pressure transducers currently used in HCCI engines. The ion current signal was very sensitive in the equivalence ratio of the intake fuel-air mixture. The N₂O mechanism was the significant source of NO_x generation in HCCI combustion. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
