| 摘要 |
A closed loop cooling water system for an internal combustion engine includes a radiator, an inlet line connecting the radiator to the internal combustion engine, a cooling water pump disposed in the inlet line, the cooling water pump having a suction side, a compensating tank, a compressor connected to the compensating tank, and a connecting line connecting the compensating tank to the inlet line on the suction side of the cooling water pump. The compressor supplies compressed air to the compensating tank to set the pressure level in the compensating tank. The pressure level in the compensating tank affects the pressure level on the suction side of the cooling water pump during operation.
