Objective
A significant increase of the peak pressure represents one of the few possibilities of increasing the efficiency of the high efficiency diesel engine even further (target: 55 %).
Specially in combination with Nox-reduction measures (Exhaust Gas Recicurculation or water injection) or with aftertreatment systems an increased peak cylinderpressure offers a high efficiency potential. New materials and design systems and methods will facilitate this undertaking. However, the success of this measure depends on the mechanical efficiency that can be achieved and on the possibilities of influencing the formation of the mixture, the combustion process, and thus the formation of pollutants. For this reason, the project focuses on the mechanical and thermodynamic processes and systems. The results are presented using a single cylinder prototype. In addition, the necessary boost systems or any downstream processes are evaluated. A multicylinder prototype that engine might be used for a follow up project would include these components, too.
In view of the fact that the Japanese and the American governments are promoting similar projects in their respective countries, European manufacturers of commercial vehicles will retain their competitiveness by increasing the efficiency of the diesel engine. On the other hand, the efforts also make sense from the point of view of environmental protection.
In addition to one manufacturer of commercial vehicles, the consortium includes one supplier of essential engine components (pistons, piston rings, liners) as well as experienced industrial development institutes for combustion engines and university institutes supporting the project through their expertise. The project receives further support from a well known manufacturer of injection systems.
