Sažetak
This paper describes the developed quasi-dimensional numerical model, implemented in the 0D numerical model for direct injection diesel engine simulation. Quasi-dimensional model uses direct solution of equations for cylinder pressure and zone temperatures, without numerical iterations. Numerical model validation has been performed on measured working parameters of the diesel engine with direct fuel injection. After a successful validation, in which simulations have been examined, the movement of various operating parameters in the engine cylinder has been performed. Operating parameters movement for the whole cylinder and the zone without combustion is shown. Except the displayed operating parameters, numerical model monitors thermodynamic processes that occur in spray fuel packages (volumes), from the beginning of the fuel injection into the cylinder, until the opening of the exhaust valves. The developed numerical model goal is to monitor a large part of the engine operating parameters, which have a major impact on the engine working process. Some of them would be difficult or impossible to measure with the existing measuring equipment. Numerical model offers accuracy and precision in the engine operating parameters prognosis. Calculation of single engine process takes less than a minute on a conventional personal computer.
