The paper presents the effect of the main parameters of pilot dose ignition: injection pressure, injection advance angle and injector opening time on the combustion process in a dual fuel diesel engine. The study continues the research conducted at the Department of Mechatronics of the University of Warmia and Mazury, Olsztyn, on optimisation of dual fuel self-ignition engines with CNG as the main fuel dose. The results presented in the paper were obtained with a single-cylinder engine HATZ 1B40, adapted to methane combustion. The results presented in the paper show the recorded changes of pressure in the combustion chamber with a constant fuel pilot dose and different ignition advance angles. Scheme of fuelling and measurement systems, view of engine indicating system, average changes of pressure in the combustion chamber, average changes of pressure in the combustion chamber and average changes of pressure in the combustion chamber at dual fuel engine supply with diesel oil at varied pilot dose injection angle, effects of advance angle of the pilot dose injection on the maximum pressure of combustion, at various proportions of diesel oil and CNG, average changes of pressure in the combustion chamber at double-fuel engine fuelled with diesel oil and various shares of methane in the dose powering the engine, CNG consumption as a function of the advance angle of the pilot dose injection for various shares of the pilot dose are presented in the paper.
