A Key Element for upcoming Euro 6 %X The Premixed Charge Compression Ignition, a low-temperature combustion strategy, is one of the most important ways to achieve very low pollutant emissions without sacrificing power and fuel consumption. By using PCCI it is possible to drastically reduce NOx and soot emissions simultaneously. Before this combustion process can be fully implemented into the serial diesel engine, it is necessary to solve some difficulties like the higher unburned HC and CO emissions, as well as the early combustion phasing. In the present study, some strategies to solve this problem are introduced. The first strategy is to find the optimum spray cone angle experimentally and with numerical methods; the second strategy is to find the optimum piston bowl geometry; and the third strategy is to find a good injection strategy. The combination of these strategies shows that it is possible to drastically reduce the pollutant emissions through the PCCI combustion concept, which is used only for low-load conditions. The high-load conditions are covered by the conventional diffusive combustion process. The transition from low to high-load conditions should be done through the injection strategy by using a combustion closed-loop control, which was developed by the Institute of Automatic Control at RWTH Aachen University. This control, however, will not be discussed in this paper.
