The authors have applied flashing spray of a mixed fuel into premixed charge compression ignition to achieve low soot and NOx while keeping high thermal efficiency because it allows early fuel injection without suffering from wall-wetting of fuel or poor mixture preparation. In this case, however, the simultaneous ignition of homogeneous mixture causes combustion noise and knocking issue. To control the mixture heterogeneity and to suppress the rapid combustion, multiple fuel injections are employed in this paper. The combustion and emissions characteristics are evaluated for several combinations of secondary injection timings and quantity ratios of each injection event.
