The temperature distribution and heat flux of the inner cylinder wall of a 4-cycle turbocharged gasoline engine were calculated by a 2-dimensional coordinate transformation. Boundary conditions of the inner wall of the cylinder were taken from the results of diagnostic engine simulations. Results show that the ununiformity of inner wall temperature of the cylinder black can be reduced by a proper choice of the thickness of fin and the distance between two cylinder blocks.
