Objectif One efficient way of reducing CO2 emission from cars is to reduce their fuel consumption. Direct-injection of fuel into a car engine reduces fuel consumption by some 25%. The best combination is with a diesel engine which is more efficient than gasoline engines. However, the drawback of direct-injection systems is the emission level of pollutants. To meet the emission levels, it will be necessary to take new paths in fuel injection and to control mixture formation and combustion processes. The objective of this research project is to quantify the potential of a DI engine concept with electronically controlled monobloc injection pump and nozzle. A prototype engine will be built and tested. Results will be compared with simulation from SPEED code. In this project, the SPEED code will be applied to design a direct-injection diesel engine with central injection. According to these results, a prototype engine will be built and tested. By comparing the simulations with the hardware test results, an evaluation of the CFD calculation can be expected. The possibility of later serial use of the concept on small car engines must be taken into account, since future fuel consumption requirements can only be met with small engines. The technical targets are: displacement: 1.6 ... 2.0 liter number of cylinders: 4 specific output: >35kW/l spec. torque: >100 Nm/l exhaust emissions: as per MVEG III noise: better than swirl chamber diesel The final results of the validation study will be made available to the participants of the IDEAEFFECT project (JOU2-CT92-0162).
