摘要

This paper presents experimental and analytical results focused on the behavior of compression ignition and ignition delay with supercritical fuel injection in the study of knock-free gasoline engine combustion development. The effect of supercritical gasoline on ignition delay was investigated using a single cylinder engine, an optical pressure vessel, and simulation. The simulation included a mixture temperature estimation model considering the energy balance for phase transition and chemical delay estimation to predict auto-ignition. In conclusion the mechanism and effectiveness of supercritical fuel injection to shorten ignition delay to realize compression ignition was demonstrated.
