N2 - In this paper the physical and corresponding mathematical models of the 3D coupled heat conduction-convective heat transfer in a cylinder and its water jacket of the automobile engine were proposed. The standard k-ε turbulence model was employed to simulate the turbulent flow in the water jacket. The empirical correlations on the in-cylinder heat transfer in conjunction with the tested combustion data were used to calculate the thermal boundary conditions of the inner wall of the cylinder. The control-volume based finite element method was used to solve the 3D coupled heat conduction-convective heat transfer problem mentioned above. The computations were carried out under different engine speed from 1500rpm to 6000rpm, and the temperature distributions in the cylinder and its water jacket were revealed in detail. The relative errors between the tested temperatures at the fixed points and the corresponding ones were within the range form -12% to 4%.
