Definitions

  • the cooling liquid in particular water, must be degassed before filling under vacuum at a pressure of 10 -4 to 10 -5 bar in order to prevent cavitation as a result of piston movement in the internal combustion engine.
  • the cooling liquid accelerates to the opposite side, which can lead to imploding gas bubbles with concomitant cavitation.
  • the cooling system is filled up to half of its volume with coolant.
