This paper describes a Ricardo research project aimed at meeting the European Stage 3 emissions targets on a direct injection diesel engine with competitive responsiveness, driveability and refinement. The objective is to demonstrate on a vehicle the technologies required for future engines integrating advanced design, fuel injection equipment, refinement and control technologies. It illustrates Ricardo's control system approach by referring to a model-based transient fueling control strategy being developed for a demonstrator vehicle. It shows how testbed, vehicle and simulation studies are integrated together for control development purposes. Simulation and vehicle results demonstrating the effectiveness of Ricardo's control methodology are also presented
