Summary:

Internal combustion engines with lean homogeneous charge andauto-ignition combustion of gasoline fuels have the capability tosignificantly reduce fuel consumption and realize ultra-lowengine-out NOx emissions. Group research of VolkswagenAG has therefore defined the Gasoline Compression Ignitioncombustion (GCI®) concept. A detailed investigation of this novelcombustion process has been carried out on test bench engines andtest vehicles by group research of Volkswagen AG and IAV GmbHGifhorn.Experimental results confirm the theoretically expectedpotential for improved efficiency and emissions behavior.Volkswagen AG and IAV GmbH will utilize a highly flexibleexternally supercharged variable valve train (VVT) engine forfuture investigations to extend the understanding of gas exchangeand EGR strategy as well as the boost demands of gasolineauto-ignition combustion processes. One of the main topics is theextension of the GCI® map area to both higher and lower brake meaneffective pressures to spread the advantage in fuelconsumption
