Opis:: The article presents the results of a numerical simulation of the working process carried out in a diesel engine. In the applied utility program DIESEL-RK, the laboratory engine Farymann Diesel type D10 was implemented. A selected inoperability of its functional fuel supply system - reduced opening pressure of the injector pinj - was introduced. The values of adequate diagnostic parameters were determined: working gas temperature in the cylinder Tcyl, exhaust gas temperature Texh, combustion (flame) temperature Tcomb and concentration of nitrogen oxides in the exhaust gas NOx. Experimental tests were carried out on the experimental engine with the inoperative condition actually introduced, analogous to the numerical simulation, and the diagnostic parameters Texh and NOx were recorded. The results obtained by numerical simulation of the processes and during the active experiment on the experimental engine were compared.

Opis:: This paper presents the effect of the main parameters of fuel injection, such as injection angle and injector opening time, on the combustion process in a self-ignition engine. The study continues the research aimed at optimising the bi-fuel feeding of self-ignition engines with a main fuel dose of methane (CNG). The results described in the paper apply to a HATZ 1B40 one-cylinder engine, which was adapted for being powered with methane. Examinations of the engine powered with a pilot dose of mechanically-injected diesel oil revealed the necessity to adjust the fuel injection advance angle. To this end, the mechanical system offuel supply was replaced with a Common Rail, with controllable fuel injection pressure, fuel injection advance angle and injector opening time. The results presented in the paper show the characteristics of the injector output depending on the fuel pressure in the Common Rail and on the duration of the electric impulse which opens the injector. Moreover, the article presents examples of pressure courses in the combustion chamber at a constant fuel dose and with a different fuel injection advance angle. An example of the combustion pressure course at a constant fuel dose and variable injection pressure and injector opening time is given.

Opis:: 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.

Opis:: One of the main problem influencing the combustion process in the cylinder of the marine engine is an fuel spray phenomena. The parameters describing the shape of the fuel spray are named macro parameters. This article presents the research results of the macrostructure parameters of the fuel spray atomized with the marine engine injector. The research were carried out by optical visualization measurement method of Mie scattering. The diameter of nozzle injector was 0.375 mm and L/D coefficient 8.3. In these research were considered different parameters of injection opening pressures and backpressures in the constant volume chamber. Generally conlusions are: the opening pressure influence on maximum spray tip penetration, spray cone angle and influence on speed of the injected fuel. The increase of backpressure into the constant volume chamber causes the reduction of spray tip penetration and the increase of the spray cone angle.
