The first part of the paper outlines the main reasons for which a G DI system offers a potential solution to meet the future EURO 2000 legislation and describes the main system structure of such a concept.
In the second part of the paper is presented a combined experimental and numerical simulation approach concept for optimisation of the charge formation in the combustion chamber. The approach is based on the simultaneous use of engine test rig experiments, detailed visualisation and analysis of injector spray formation and intensive use of 3D multiphase numerical simulation.
The paper concludes with some suggestions for useful work to be done in a nearby future in order to improve the computational and experimental optimisation tools.
