01-10-50 Lubricating System Description
General:
The lubricating system of the AE300 consists of an internal chain driven oil pump, which pumps the
engine oil through the oil filter, the coolant/oil heat exchanger and the lubrication ports of the engine.
The lubricating system is part of the engine. A coolant/oil heat exchanger as part of the engine
provides the oil cooling. Dependant on the coolant temperature the oil temperature is obtained. If
necessary the cooling capacity can be increased by an airstream over the oil sump.
Below the injector cover an oil separator is installed. The breather air out of the crankcase is guided
through an oil separator. Downstream the oil separator the crankcase air is released through the
breather line into the environment. The outlet of the oil separator at the injector cover has to be
connected to a breather line provided by the OEM. The oil separator is protected with an overpressure
relief valve.
In front of the oil filter the oil pressure is measured. The oil temperature is measured in the oil sump
next to the oil filler neck.
