Definitions

  • the cooling chamber 2 of the cylinder block, the lower chamber 5 for cooling the cylinder head and the upper chamber 6 cooling of the cylinder head are able to be traversed by the cooling fluid.
  • the upper chamber 6 for cooling the cylinder head is thus supplied with cooling fluid by the chamber 2 cooling the cylinder block and therefore no longer needs to be in contact with the cylinder head gasket 7. This avoids the presence of an area of complex geometry in the upper chamber 6 for cooling the cylinder head.
  • the cooling fluid is typically a coolant.
  • the coolant is conveyed into the cooling chamber 2 of the cylinder block by the pump 3. Part of the coolant passes from the cooling chamber 2 of the cylinder block to the lower chamber 5 of the cylinder head. through the orifices 8 located in the cylinder head gasket 7.
