【Abstract】 With adiabatic diesel Type 165 taken for an example, gas leakage between ringless piston and liner is studied experimentally and theoretically. A mathematical model is proposed for calculating the blow-by gas flow between them, the effects of engine speed, clearance width and gas viscosity on the gas leakage are analysed and the gas leakage characteristics derived.更多还原
