Simulation Analysis of the Combustion Process of YN4100QB Diesel Engine
In order to obtain the foundation to the research on the Diesel Engine YN4100QB combustion process , exhaust, the optimal design of combustion chamber and the useful information for the design of muffler, the geometrical model and mesh model of a type internal combustion engine were constructed by using FIRE software to analyze the working process of internal combustion engine. Based on the model and combustion theory, the relevant calculation model and initial parameters were chosen and applied into the software. There are 5 load cases were designed according to the true running process of this engine. The detail distribution of the parameters such as combusted gas pressure, combusted gas temperature and velocity of the flow fields in cylinder has been obtained and the relation of these parameters and crankshaft angle was given for the further research, at the same time, also got the exhaust situation of NOx . The numerical results of the simulation of combustion process showed that the simulation not only defined the 3D distribution of the parameters in the cylinder to the research on the combustion process and exhaust and the optimal design of combustion chamber, but also provided the useful information for the designs of muffler.
