Multiple-Cylinder Diesel Engine CFD Simulation Using VECTIS

摘要

This paper presents the CFD simulation performed on a 4-cylinder in-line diesel engine using Ricardo's engine focused commercial CFD code VECTIS. Simulation ran through multiple cycles and covered processes of intake, compression, spray, combustion and exhaust. The cyclically converged solution is compared to the engine test data for cylinder pressure, charge distribution and EGR distribution, etc.... Technical issues concerning multiple-cylinder analysis are discussed.
