The purpose of the proposed research is to elucidate fundamental aspects of an alternative approach to conventional DISI engine operation at low- and part-load operating conditions; namely, unthrottled homogeneous-charge operation by means of a fully variable valve control strategy. The work is motivated by: concerns over the ability of stratified-charge DISI combustion systems to meet future particulate emissions standards, and by the anticipated future availability of FVV operating systems. Complementary research programmes will be performed at Loughborough and UCL, using a common test matrix to incorporate a range of valve operating strategies, in particular early intake valve closing (EIVC) and late intake valve opening (LIVO). Experiments will be performed at Loughborough University to: determine the bulk in-cylinder air motions, quantify the effects of in-cylinder fuel injection on the air motion, and evaluate the effects of EIVC and LIVID strategies on air-fuel mixture preparation in DISI engines. Experiments at UCL will quantify the effects of EIVC and LIVO strategies on DISI engine fuel efficiency and C02 reduction, versus the emission of particulates, which are potentially hazardous to the human respiratory system. Combustion stability and emissions of conventional exhaust pollutants will also be quantified. The UK has a substantial business in engine design and consultancy for the global marketplace. The link between the in-cylinder mixture preparation and the environmental performance of the same combustion system will provide timely data for this industry, as it seeks robust, low C02, low particulate operating strategies during the next two decades.
