Próba oceny wpływu kąta początku wtrysku inicjującej zapłon dawki oleju napędowego na podstawowe parametry pracy dwupaliwowego silnika o ZS zasilanego głównie mieszaniną butanu i powietrza

In the Department of Internal Combustion Engines and Automobiles in Technical University of Radom, compression ignition engine has been modified to dual fuelling. As main fuel liquid petroleum gas (LPG) is used. The diesel fuel is used to initiate of combustion. Some investigation of standard diesel engine and modified one has been carried out. During these test the load characteristics of engine for different regulations of injection angle were prepared. To analyse of the combustion process some histories of cylinder pressure have been registered. These histories have been used for calculation of some combustion parameters such as maximum pressure and average rate of pressure rise. Ali registered parameters of modified engines have been compared with parameters of standard diesel engine. Results of investigation shows that diesel engine may be fuelled with LPG, while diesel fuel dose is used only for ignition. The value of regulation of injection angle influences combustion parameters as well as engine performance.
