Simulation and Experimental Analysis of Piston Temperature Field in Gasoline Engine Development
In this study,the finite element method was used to analyze the temperature at different measurement points of the piston,and the hardness plug method was used to measure the temperature of the piston surface and the inner side of the pin control.The re-sults showed that the overall distribution of the piston surface temperature field was normal,with a decreasing trend from the top of the piston to the bottom.During the entire engine testing process,all performance parameters remained consistent,without significant fluc-tuations,which verified that the test can better reflect actual operating conditions with accurate and true results.Therefore,the finite element method has a high accuracy in calculating the temperature at various points of the piston,and the hardness plug method for pis-ton temperature measurement is safe,convenient,and reliable,which can effectively reflect the temperature of the piston at various working conditions in the engine.The temperature measurement data not only provides a basis for combustion data stereotyping and pis-ton design stereotyping in engine development,but also accumulates experience for future piston development and design work.
