| Abstract: | Based on the measurements of transient temperature on cylinder head wall in Model 190A diesel engine, the heat transfer processes in cylinder are analysed. As for different kinds of designs and cooling conditions, the temperature fields of pistons were computed by means of finite element methods. The analyses of thermal insulation mechanism and design provided a guidance for reducing heat loss in diesel engines. |
