Characteristics of HCCI Combustion in Homogenized Temperature Fields using a Super Rapid Compression Machine 2011-01-1761

Homogeneous Charge Compression Ignition combustion in homogenized temperature fields was investigated experimentally using a super rapid compression machine. Temperature fields before a blue flame occurs are thought to control the burning process. The time of blue flame occurrence, burn rate and ignition delay time were measured. Temperature homogeneity before a blue flame occurred was controlled by two means. One was by the piston shape which controlled the roll-up vortex and the other was by the heat release of low temperature reactions that has a homogenizing effect. It was found that homogenized temperature fields contribute to the occurrence of a homogeneous blue flame while inhomogeneous fields produce an uneven occurrence.
