WebbSeveral approaches have been developed to measure instantaneous friction between the piston assembly and cylinder in internal combustion (IC) engines, such as floating-liner, reciprocating liner, instantaneous mean effective pressure (IMEP), fixed sleeve, and (P-ω) method and tribological bench tests. However, the “floating-liner method” and the … Webb1 dec. 2024 · The skirt contact pressure calculated by piston dynamics is shown in Fig. 8. The simulation results show that the whole TS surface of the uncoated piston skirt …
