COOLING SYSTEM
COOLING SYSTEM DESCRIPTION
The engine cooling is carryed out by means of air blown by the centrifugal fan, attached on the flywheel, on the cylinder head
unit .
The heat is removed from the cylinder and cylinder head through the appropriate finning of themself. Moreover, particularly
in the cylinder head area, close to the exaust valve seat and to the pre-combustion chamber, the heat is removed by the
lubrication oil, as previously described in the chapter relative to the lubrication system. When the engine is cold, because of
high oil pressure due to the high viscosity, a by-pass valve limits the oil quantity sent to the area to be cooled.
