Combustion chamber deposits (CCD) in wall-guided stratified charged direct injection spark ignition (DISI) engines affect combustion significantly because CCD may disturb the air-fuel mixture formation and, as a result, cause emission deterioration. For the design of engines and fuels, it is therefore important to determine the effects of CCD on emissions from DISI engines.In this study, the effects of CCD on emissions from a DISI engine using different fuel distillation properties were investigated. The study results show that, during stratified charged operation, an increase in CCD increased the total hydrocarbon (THC) emissions under high speed conditions and the NOx emissions under the low speed conditions.
