ABSTRACT
In the Internal - Combustion Engines and Vehicles Division of the Humanistic-Technological University named after Kazimierz Pułaski in Radom there have been carried out research for many years on self-ignition dual-fuel engine with using different substitute fuels of low value of cetane number. Previous research showed possibilities of using considerable energy fractions of gaseous fuel [1, 8, and 9]. In the present paper there are presented selected results of research concerning utilization of natural gas. During execution of examinations it was observed that together with the change in energy fraction of gaseous fuel and change of degree of recirculation of exhaust gases the change of overall efficiency of engine as well as the change of parameters of combustion process takes place. In this paper there was made an attempt of evaluating the impact of application of different fractions of gaseous fuel and the degree of recirculation of exhaust gases on the parameters of combustion process. There was also made an attempt to clarify causes of the changes in values of overall efficiency as a result of observed changes in the course of combustion.
