Requirements for further reductions for fuel consumption and emissions might be met by using HCCI combustion, provided that certain challenges can be overcome – the most important of which is to develop ways to control the combustion. In this study a combination of SI and HCCI combustion was investigated, in which a SI stratified charge is used to initiate the HCCI combustion. Both hydrogen and a mixture of iso-octane and n-heptane were used as fuels for the stratification charge. The hybrid combustion concept was found to give better control of combustion timing and the CA50 could be controlled by varying the injection timing and stratification amount.
