Simulation of a 4-Cylinder Turbocharged Gasoline Direct Injection Engine Using a Direct Temporal Coupling Between a 1D Simulation Software and a 3D Combustion Code 2006-01-3263

This paper presents a novel methodology to investigate engine behaviour using an original numerical approach based on the direct temporal coupling between IFP-ENGINE, a 1D engine simulation tool used for the simulation of the gas exchange system, and IFP-C3D, a 3D CFD code used to simulate combustion and pollutant emissions. The coupling method is used to compute steady conditions of the whole engine dynamic system but could also be applied for transient operating conditions. To demonstrate the capabilities of the model a 4-cylinder turbocharged gasoline engine is modelled at two different operating points and the comparison with experimental measurements is shown.
