Sažetak
This paper presents and explains the results obtained in a study on multiple injections in slow-speed two-stroke marine diesel engines. The study included a simulation model of engine operation processes. The validity of the model was verified by comparing the obtained values with the measured values on three types of engines, Wärtsilä 7 RT Flex 50, MAN B&W MC 50 and ME 60.
Pressure and temperature values in the engine cylinder were obtained for every degree within a single full crankshaft revolution for two types of fuel injection: conventional and multiple fuel injections.
Even though the experiments were carried out with five, six and seven injections, the study has been restricted to three injections for practical purposes.
Pressure and temperature parameters are processed in tables and charts. First and second time derivatives of pressure and temperature were calculated, i.e. the rate of change of pressure and temperature and the acceleration of the rate of change in pressure and in temperature were calculated.
