| Abstract: | Dealt with are factors affecting the heat loss and thermal load of combustion chamber components.The finite element method is used to calculate the temperature field and heat flux distributions of the components, and the results are experimentally verified. Comparisons are made of thermal loads and heat losses for various structure designs and cooling schemes, and the analysis is made of the effects of the wall temperature on diesel engine performance.Finally the optimum designs are presented of combustion chamber components. |
