Das Projekt "Plattform zu Simulationswerkzeugen selbststartender numerischer Antriebe" wird vom Umweltbundesamt gefördert und von Mercedes-Benz Group AG durchgeführt. The PLANET project goal is to develop engine knowledge and design technologies to support the development of a new combustion concept. Homegeneous Charge Compression Ignition (HCCI) has potential of a very significant pollutant reduction (NO and particulate) while keeping or increasing the efficiency of the best transportation engine today, the Diesel engine. This pollutant reduction should come with very simple and cheap exhaust gases treatment. The PLANET project is aiming to provide an extensive basic knowledge of HCCI combustion and to develop modern computer simulation tools to support industrial engine design. The project comprises a first phase devoted to experimental investigation to homogeneous charge and stratified engines using powerful new diagnostic techniques. The resulting data bases will serve for the understanding of HCCI and the validation of the physical models developed in the second phase. The resulting CFD models for HCCI combustion will be implemented into industrial engine design codes and will allow the efficient design of HCCI engines. The CFD tools will also be available for the clustered SPACE projects.
