The purpose of this paper is to compare defferent methodologies of CFD analysis, applied to the intake plenum of a turbocharged HSDI Diesel Engine. The study is performed by using both an engine cycle simulation code and a 3D-CFD code. Experiments at the engine dynamometer and at a steady flow bbench support the theoretical study.The most promisig simulation technique presented in the paper is the integrated 1D and 3D-CFDsimulation. This numerical approach showed itself to be particularly suitable for analysing complex engine components where the flow patterns are fully transient.
