LUBRICATION
Lubrication by forced circulation is achieved through oil rotary
expansion pump (1), placed in the front part of the basement,
driven by the straight-tooth gear splined to the shaft’s bar hold.
From the pan, the lubrication oil flows to the driving shaft, to
the camshaft and to the valve drive.
Lubrication involves the heat exchanger as well, the turbo-
blower and the eventual compressor for any eventual com-
pressed air system. All these components may often vary ac-
cording to the specific duty and will therefore be examined in
the specific section.

6-cylinder engine version
Even for the 6 cylinders version lubrication is obtained by
forced circulation and achieved through an oil rotary expan-
sion pump similar to the 4 cylinders’ one.
Also in this case, the components such as the oil exchanger,
the turbo-blower and the eventual compressor are specifically
studied and made out to suit the equipment or the duty for
which the engine has been developed.
