Auto-ignition, which is observed in homogeneous and premixed charge compression ignition engines, allows expansion of the lean flammability limit of engine operation and realization of stable ignition and combustion over a range of ultra-lean conditions, where NOx emissions are very low. In this study, the basic combustion mechanism of auto-ignition and combustion was studied with initial mixture temperatures and compression speeds for n-butane and dimethyl ether. A single-mode type heat release process was observed with n-butane in the homogeneous charge compression ignition test engine.
