Development of the theoretical model for the optimal design of surface texturing on cylinder liner

► Based on the Reynolds equation and the dynamic operation conditions of cylinder liner/piston ring, the theoretical models of the load carrying capacity and film thickness were developed. ► Ranges of the optimum texturing parameters were found. ► Texturing with variable parameters in different velocity ranges can produce higher load carrying capacity and thicker film than that with invariable parameters. ► An optimal texturing design method on cylinder liner was proposed.
