OIL SYSTEM – DESCRIPTION AND OPERATION
79-10 OIL SYSTEM
DESCRIPTION AND OPERATION
The A/C is equipped with oil system that is designed to supply the engine with
the appropriate quantity of oil (13 lt/min) at a temperature not above that safe for
continuous operation.
The engine is equipped with a dry sump forced lubrication system, with a main
oil pump, with integrated pressure regulator and oil pressure sensor. The oil
pump sucks the oil from the oil tank via the oil cooler and forces it through the
oil filter to the designed points of lubrication. Drainage device is provided.
The main components of the oil system are:
 Oil filter
 Oil radiator
 Oil reservoir
 Thermostatic valve
 Oil drain valves
 Oil vent valves
 Oil filler
 Oil quantity measurement device (stick type)
Anyway the complete oil system of the A/C is composed of the following addi-
tional parts for each engine:
 Oil temperature sensor
 Oil pressure sensor
The above mentioned oil parameters are monitored by means of analogical
transducers, located on the instrument panel (right side).
By means of the thermostatic valve, which regulates the oil flow to the heat ex-
changer (oil radiator), the oil distribution follows two different paths depending
upon the oil temperature.
As hereinafter described, when the engine is cold, the valve limits the flow to the
radiator allowing for a faster engine warm-up. The same occurs in cold OAT
conditions. When the oil temperature rises, the flow to the radiator is augmented.
