Cooling system

Abstract

Provided are a cooling system and a method for controlling the same, with which it is possible to bleed air in a coolant flow path, quickly raise a coolant temperature to quickly heat air during air-heating, and quickly lower the coolant temperature to minimize knocking early when knocking occurs. A cooling system 1 comprises a main passage L1 through which a coolant is circulated between an internal combustion engine 2 and a radiator 3, an auxiliary passage 12 through which the coolant is circulated between the internal combustion engine and heat exchangers 4, 5, 6, a thermostat 7 that opens and closes the main passage L1 in response to the coolant temperature, a thermostat bypass path L3 that bypasses the thermostat 7 to allow communication between the internal combustion engine and the radiator, and a motor-operated valve 8 that opens and closes the auxiliary passage and the thermostat bypass path.

Dependencies are inferred from the claim text.
