The Design of Turbocharged Engines Using 1D Simulation 2001-01-0576
1D wave action simulation has been used to construct models of a number of turbocharged spark ignition engines. This paper describes how the models have been applied in the development of those engines.
The simulation has been used to optimise a number of components including the inlet and exhaust manifolds, the valve timing and the turbo match. The models have been validated against test data.
The method of modelling unsteady flow is described and the behaviour of the turbocharger in unsteady flow investigated.
