The distortion of the cylinder liners of internal combustion engines has a significant affect on engine operation. It can affect the oil consumption, the blow-by, the wear behavior and, due to friction, the fuel consumption. In order to achieve future requirements regarding exhaust emissions and fuel consumption, the development of low distortion engine blocks will play a significant role. Finite element method with experimental data were used to calculate and analysis the temperature field and machine assembly of a 150 engine cylinder liner in this paper. It can provide a theoretical basis for the controlling of the cylinder liner deformation.
