OIL PRESSURE MONITORING METHOD FOR A DIESEL ENGINE, CAPABLE OF LIGHTING A WARNING LAMP FOR THE REPLACEMENT OF ENGINE OIL

摘要

PURPOSE: An oil pressure monitoring method for a diesel engine is provided to enable a user to check the time to replace engine oil by determining the oil replacement of a diesel engine through the oil pressure of a diesel engine.;CONSTITUTION: An oil pressure monitoring method for a diesel engine comprises following steps. Whether a vehicle has moved over constant mileage or a vehicle is traveled up to constant km after the completion of post-injection is determined(S16). If the first step is satisfied, whether or not an engine operation condition for measuring engine oil pressure is measured is determined(S18). If the second step is satisfied, whether or not the operation condition of the second step is maintained for fixed time(S20). If the third step is satisfied, the engine oil pressure is measured(S22). Whether or not the engine oil pressure measured in the fourth step is less than the preset limit value at the engine drive condition of the second step(S24).;COPYRIGHT KIPO 2010
