To study the influence of different influencing factors on the cylinder liner deformation characteristics, the finite element method was used to analyze the cylinder liner deformation under the pre-tightening condition of the diesel engine block-cylinder head assembly. Fourier spectrum, coaxiality, and main thrust surface inner diameter change were selected as deformation evaluation indicators to comprehensively evaluate cylinder liner deformation. The influence laws of several typical load parameters, structural parameters, and material parameters on cylinder liner deformation have been studied and sensitivity has been used to characterize the degree of influence of influencing factors on each deformation evaluation indicator. The research results can guide the evaluation and control of cylinder liner deformation under the pre-tightening condition.
