Abstract
Maritime University of Constanta, Faculty of Naval Electromechanics, 104 Mircea cel Batran Str., 900663, Constanta, Romania Combustion inside diesel engine cylinders is the critical factor that controls the emission and combustion gases. Fuel injection in the engine cylinder is the decisive factor in the combustion of diesel engines and, consequently, combustion can be effectively controlled if the fuel injection process is efficiently controlled. From this perspective, the simulation of the complex processes of fuel injection in diesel engines in various situations can make a positive contribution to the optimization of marine propulsion systems. Also, correct dimensioning of the injection system components and its optimization and, implicitly, the combustion parameters, can have positive results in the context of reducing the impact of combustion gases of internal combustion engines, on the greenhouse effect and global warming.
Highlights
If howeverThere is insufficient prepared fuel in the cylinder for combustion to proceed in this way and combustion is assumed to be controlled by the rate of preparation and fuel burnt is the:
The emergence and development of computing techniques, electronic computers, have been instrumental in developing modelling
Are presented the particle traces colored by temperature [K], in figure 6 the particle traces colored by velocity (m/s), in figure 7 the contours of static temperature [K], in figure 8 the contours of velocity magnitude [m/s], and in figure 9 the contours of velocity magnitude [m/s]. This theoretical work represent an extremely detailed inventory of the thermodynamic models and the dynamic phenomena occurring in combustion chambers of diesel engines, as follows:
Summary
There is insufficient prepared fuel in the cylinder for combustion to proceed in this way and combustion is assumed to be controlled by the rate of preparation and fuel burnt is the:. Using the mass of fuel burnt in each step of the cycle calculation can be determined the value of heat release dQc:. There QI is the lower specific heat value of fuel [5]
