Description: Das Projekt "Variable compression ratio for CO2-reduction of gasoline engine" wird vom Umweltbundesamt gefördert und von FEV Motorentechnik GmbH durchgeführt. Objective: With increasing CO2-emissions and reducing oil resources fuel economy improvement of passenger car S.I. engines has become a major issue. A promising approach is the reduction of pumping and friction losses by shifting the operation point t o lower engine speed/higher load by engine down sizing. This requires small supercharged engines with a high specific power (kW/litre). To improve part load efficiency and to avoid full load knocking these engines must have a Variable Compression Ratio (VCR). A down-sized, highly boosted engine with variable compression ratio has a 30 percent fuel saving potential compared to a model year 1998 vehicle an d has simultaneously low exhaust emission levels as 'a=1.0-concept' with the well developed TWC technology. The goal of this project is to demonstrate these benefits through single-cylinder investigations with different VCR mechanisms as well as multi-cylinder test bench and in-vehicle investigations. As a final output, the industrial feasibility and the costs of such an engine concept shall be demonstrated. Prime Contractor: FEV Motorentechnik GmbH & Co. KG; Aachen; Germany.
