| Abstract: | A mathematical model of piston skirt in lubrication is presented, considering the effects of surface roughness and piston skirt surface profile on piston motion. The corresponding computer program is developed to calculate the crosswise piston trajectory and the hydrodynamic and friction forces as a function of crank angle under running conditions. Basic equations and some preliminary results are also given. |
