N2 - The direct-injection stratified-charge engine has the advantages of higher thermal efficiency and less CO and NOx emission levels than conventional spark ignition engines. However, its actual utilization is prevented by high unburned hydrocarbon emission levels during light-load operations. In order to reduce the unburned hydrocarbon emissions, the effects of intensification of local premixing by radial fuel injection were examined experimentally using a pancake-type constant volume bomb. Unburned hydrocarbon emission levels by this “locally homogenized DISC system” with radial fuel injection were shown to be lower than those of tangential fuel injection cases. Moreover, the emission levels were discussed by comparing them with unburned hydrocarbon levels of premixed turbulent combustion.
