Analysis of Choosen Parameters of Dual Fuel CI Engine Fuelled With Propane-Butane Gas as a Main Fuel 2002-01-2234

In the Department of IC Engines and Automobiles in Technical University of Radom, CI engine has been modified to dual fuelling. As a main fuel liquid petroleum gas (LPG) is used. The diesel fuel is used to initiate combustion. Some investigation of standard diesel engine and modified one has been carried out.
Tests of the engines consisted of preparation of load characteristics for some different ignition diesel fuel doses and for different injection timing of ignition dose. The emission of exhausts gases and histories of pressures as a function of crank angle has been measured during examination of the engines. It was noticed that the volume of ignition diesel oil dose and injection timing strongly influences overall efficiency, maximum engine torque and emissions and value of combustion process parameters. Combustion process was analysed in details in order to explain the causes of improvement of engine overall efficiency as well as possibility of knock combustion appearance in examined fuel system.
