Lubrication system:Lubrication system:
What role has the oil in the engine:
• It reduces friction of sliding surfaces and prevents seizures.• It fills gaps between metal parts and seals the combustion chamber to prevent leaks of combustion energy.• It rinses away carbon and impurities produced by combustion. • It protects metal parts from corrosive products with oil film, thus preventing rust.
Instructor: Jean Joris Service Department22
Cooling system:Cooling system:
- System is forced circulation type.
- Coolant is sucked by the water pump out of the radiator via the cylinders through the cylinder head thermostat.
- When the coolant is below 76.5°C it circulates via a by-pass to the water pump and back into the cylinder block.
-When the coolant goes over 76.5°C the thermostat gradually opens and the coolant flows direct into the radiator. (thermostat max. open at 90°C)
