Abstract: One tendency in the field of hybrid vehicles is the development of internal combustion engines specialized for driving electric generators, regarding range extender application [3]. The requirements of this application are: small fuel consumption, emissions within the imposed limits and last but not least, reliability [1], [2]. Most engine manufacturers for hybrid vehicles have oriented themselves towards spark ignition engines. The paper analyses the limits and possibilities in which the burning process parameters and real cycle ones can be improved, for a compression ignition engine. The working regimes are set at constant load and speed, typical for the engines used for driving electrical generators. The theoretical and experimental evaluations are realized on a single cylinder AVL 5402 engine. The started research enhances the influence of the main parameters on the energetic performances of the engine cycle. The results obtained will be used for the predevelopment of a diesel engine for a hybrid vehicle.

Keywords: injection; multiple injection; combustion; range extender.
