Under pressure: Pierburg takes MIM readers through the oil circuit pressurising procedure

摘要

Only when the oil pressure system has been correctly filled with oil and the system is free of any air, can oil pressure be built up by the engine oil pump. If an engine is started in a dry state, under certain circumstances it will take too long until the oil reaches the plain bearing locations. It is for precisely that reason the connecting rod bearings suffer extreme damage under these conditions.
