Abstract
The EcoDrive project aims at reducing fuel consumption while maintaining good driveability and performance for mid-class passenger cars with Continuously Variable Transmission. The key element in the development is the push-belt type CVT. The approach is to match both Diesel and gasoline engine and transmission layout for optimum fuel economy, performance and driveability. Aspects like emissions, cost and weight are also considered. At this level of detail, CVT ratio coverage, transmission efficiency, engine displacement and engine breathing are considered as layout parameters. The present paper gives the results from this study.
