Abstrakty
W artykule omówiono wyniki badań wpływu strategii podziału dawki paliwa na wskaźniki spalania oleju napędowego wraz z analizą spalin z Maszyny Pojedynczego Cyklu. Analizie poddano także materiał zdjęciowy dotyczący okresu od początku wtrysku dawki paliwa do początku wystąpienia ognisk spalania. Dokonano wariantowania liczby dawek ich wielkości oraz czasów przerw między nimi, a także współczynnika nadmiaru powietrza. Dokonano oceny porównawczej wskaźników termodynamicznych procesu spalania uzyskanych z wykresu indykatorowego (Pcyl-max, (dPcyl/dt)max, czas opóźnienia zimnych i gorących płomieni) w zestawieniu z materiałem filmowym.
The results of research on the influence of the fuel dose division strategy on the operational and optical indexes of the engine and combustion process have been discussed in the paper. The paper also contains an exhaust gas analysis conducted with the use of a Rapid Compression Machine (RCM). The recorded images related to the period from the onset of injection to the beginning of combustion spots have also been analyzed. The following have been varied: number of doses, the size of doses, dwell times and the excess air coefficient. The author performed a comparative analysis (against the recorded images) of the thermodynamic indexes of the combustion process obtained from the indicator traces (Pcyl-max, (dPcyl/dt)max, delay time of the hot and cold flames).
