摘要：

In the view of incompleteness of diesel engine cylinder block deformation evaluation methods in China, proposals to take coaxality, cylindricity, roundness and light-seal degree of each section as evaluation index of cylinder bore and planeness as evaluation index of plane deformation were presented and explained in detail. Using FEM, structural analysis for single cylinder diesel engine cylinder block was conducted and the new deformation evaluation method was used to compare stiffness of cylinder block for different schemes. Results show that the new deformation evaluation indexes can assess engine block deformation effectively. Compared with original cast iron cylinder block, the designed newly cast aluminium alloy cylinder block have a series of improvements, cylindricity error of cylinder liner bore reduces significantly and roundness and light-seal degree of each section of cylinder liner decline. In addition, deformations of other holes and planes all can meet the requirements. Compared with the changed simply to cast aluminium alloy cylinder block, its stiffness get a great optimization. ©, 2015, Chinese Society for Internal Combustion Engines. All right reserved.
