内燃机工作过程模拟分析与研究

Simulation and Analysis of the Engine Combustion Process

采用FIRE软件进行了内燃机工作过程的数值模拟分析,得到与排气噪声影响因素有关的燃烧气体的温度、压力参数,同时还得到了在这些工况下NOx的排放情况,为发动机的燃烧、排放以及燃烧室的优化设计等的研究提供了基础,同时还为进一步设计发动机消声器提供了信息。

It applies FIRE software to simulate the combustion process of engine and obtains the detail data such as the parameters of combustion gas pressure, temperature, combustion noise and exhaust situation of NOx. The numerical results indicate that the simulation of combustion process not only builds the foundation of research on the combustion process, exhaust and the optimal design of combustion chamber, but also provides useful information for design of muffler.
