Cyclic variations focus of new European engine research project

  • 23-Apr-2010 12:49 EDT

The European research project called Large-Eddy & System Simulation to predict Cyclic Combustion Variability in gasoline engines (LESSCCV) recently was launched. Part of the Seventh Framework Programme for Research and Technological Development, the LESSCCV project aims to significantly improve the understanding and the modeling of cyclic variations in some major types of spark-ignition engines. The objective is to limit the negative impact of these phenomena on fuel consumption and emissions. Coordinated by IFP, a public-sector energy and technology research organization based in France, the project brings together seven partners, including research institutes, software editors, and universities. The partners include AVL, FEV, LMS-Imagine, Ricardo, Technical University of Prague, Polytechnic of Milan, and University of Western Macedonia. According to IFP, the causes of sometimes unstable operation of a four-stroke engine from one cycle to another are still poorly understood under certain conditions. This, in turn, limits the benefits of new powertrain concepts such as downsized engines, particularly in terms of cutting CO2 emissions. The work carried out as part of the LESSCCV project will rely to a large degree on IFP’s expertise in the fields of 3-D large-eddy simulation and system simulation.
