The Design of Turbocharged Engines Using 1D Simulation

Abstract

<div class="htmlview paragraph">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.</div> <div class="htmlview paragraph">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.</div> <div class="htmlview paragraph">The method of modelling unsteady flow is described and the behaviour of the turbocharger in unsteady flow investigated.</div>
