Current production SI engines with a three-way catalyst suffer from poor fuel economy and, hence produce high CO2 emissions. Although all the known lean burn engines offer improvements in fuel economy, they require a rather complicated and expensive DeNOx catalyst system, which is still under development. Recently an ultra-low NOx combustion process has been identified and applied to IC engines, which is referred to as PCCI combustion in this proposal. An IC engine employing PCCI combustion can provide similar fuel economy and CO2 emissions to an equivalent IDI diesel engine with ultra low NOx emissions, combined with the advantages of very low particulate emissions and high specific power output of an SI engine due to the use of premixed charge.The proposed work will investigate this new combustion process, particularly the effects of fuel and EGR on PCCI combustion and its emissions. Advanced laser diagnostics will be used to study the mixture distribution and PCCI combustion, together with exhaust gas analysis and heat release analysis.The use of PCCI combustion will provide a new class of IC engines that combines the high efficiency of diesel engines at part load with the high specific power output of SI engines at full load, without the need of a complicated and expensive DeNOx catalyst. This will also provide a good answer to the possible European legislation on CO2 emissions in the future.
