文摘The physical model of -20 diesel oil and force model of injector controlvalve of common rail system is built. The changes of the fluid thickness are investigated on thebase of the results of CFD and experiments for control valve of injector. The results indicate thata fluid thickness of 0.02-0.03 mm between the poppet and valve guide is sufficient to dampen anyexcessive control valve poppet bouncing.
