Study on Optimization of the Specifications of Highly Supercharged Downsized Gasoline Engine Using 1D-CFD Simulator and Optimization Software

Abstract

Using newly developed 1D-CFD simulator of turbocharged gasoline engine, which can predict knocking and combustion phenomena, we created new supercharged engine concept and optimized its main specifications by combining with optimization software. The engine produces 30 bar in BMEP. The optimized specifications and the potential of the concept including the possibility of high compression ratio are reported
