Objective Objectives and content The development of low noise/vibration emitting engines for passenger cars is still a costly and time consuming experimental process. In the case of DI Diesel engine, which is the most fuel efficient engine on the roads, it is even questionable whether such a procedure would eventually lead to powertrains able to comply with the vehicle-noise-emission levels expected to become effective at the end of the nineties. In order to face the competition of the non-European car manufacturers (first of all the Japanese) it is necessary to acquire the capability of developing silent DI Diesel engines more in the Design Offices than in the Test Laboratories. This would drastically reduce costs and time-to-market. The research will: - develop a design methodology, mostly relying on computer simulations, to assist the design of low noise and vibration emitting engines since its very first phases - develop engine prototypes achieving noise reduction of about 3dB(A) with reference to current DI Diesel engines and featuring noise level not more than 1 dB(A) higher w.r.t. todays' gasoline engines. These objectives will be achieved by "redesigning" for low noise/vibration emissions two DI Diesel engines of the most up-to-date design (one Mercedes Benz and one Flat) featuring significant differences in the design criteria. The main research phases will be: - set up of the computational tools by comparison with the results of in-depth experimental evaluation of the two baseline engines - identification of design solutions for engine structures and components through computational analysis and experimental verification - design, manufacturing and experimental demonstration of the two low noise emitting prototype engines. The immediate outcome of this programme will be a validated methodology for designing the new generations of DI Diesel engines for passenger cars, together with examples of the basic technology which will enable them to comply with the future noise standards. The Consortium comprises two major European vehicle manufacturers, FIAT Research Centre and Mercedes Benz, who will develop the prototype engines, a big European automotive component manufacturer like VALEO who will develop the double mass flywheel devices and a leading research and development centre for internal combustion engines like AVL who will further enhance the simulation software and assist the other partners with computational analysis.
