In this study, we made a basic research on mechanism of auto ignition and combustion with various premixed gas temperature and compression speed on n-butane and dimethyl ether (DME). And we observed singularity phenomena appearing in auto ignition at low temperature of n-butane/air mixture in Homogeneous Charge Compression Ignition engine.Read More
