Description of the Project
Objectives
A. To meet 40% lower CO2 emissions with respect to the 2005 figures for spark ignited (SI) engines powered vehicles and 20% lower CO2 than the 2005 level for compression ignition (CI) engine powered vehicles with comparable fun-to-drive figures of the 2005 vehicles.
B. To meet CO, HC, NOx and PM figures, as engineering targets, at least 10% less than the Euro 6 emissions limits shown in Table 1.1.
C. To maintain the CO2 and pollutant emissions levels during the useful engine life and keeping into account real world emissions, i.e. in accordance not only with the standard NEDC (new European driving cycle) but also with the Artemis duty cycle (Fig. 1.1). Furthermore the PEMS procedure will be applied to vehicles independently on any cycle.
D. By fulfilling the above targets, the realization of the LEEV (Light-duty Environmentally Enhanced Vehicle) concept, defined as a vehicle that both meets the next stage of pollutant emission limit values and stays below the above mentioned level of CO2 emissions.
To achieve the POWERFUL targets, 4 projects will be carried :
V1. An advanced four-stroke SI engine concept characterized by low-cost / low emissions;
V2. An advanced four-stroke CI engine concept able to run also on new tailored fuels and integrating the LTC (low temperature combustion) mode in the CI combustion system;
V3. An advanced two-stroke CI engine concept running on diesel fuel and integrating the LTHC (low thermal homogeneous combustion) mode in the CI system.
These advanced engine concepts will be accompanied by a transversal sub-project T1 taking care of the development of:
- new simulation tools describing the strong interactions between combustion systems and engine architecture;
- means for reducing engine frictions and performing an intelligent energy management;
- PEMS (portable emissions measurement system) approach.
