燃機関の冷却装置。 An in-head cooling water passage provided in the cylinder head, an in-block cooling water passage provided in the cylinder block, a radiator, a cooling water pump,
a head side temperature sensing valve connected to the cooling water inlet of the head internal cooling water passage; a block side temperature sensing valve connected to the cooling water inlet of the block internal cooling water passage;
A pump connection passage connects the cooling water outlet of each of the head internal cooling water passage and the block internal cooling water passage to the cooling water inlet of the cooling water pump, and the cooling water discharge port of the cooling water pump is connected to the cooling water outlet of the radiator. A radiator connection passage connects to the cooling water inlet, a head side cooling water passage connects the cooling water outlet of the radiator to the head side temperature sensing valve, and connects the cooling water outlet of the radiator to the block side temperature sensing valve. a block-side cooling water passage; a head-side bypass cooling water passage that connects the cooling water outlet of the cooling water pump to the head-side temperature-sensing valve; and a head-side bypass cooling water passage that connects the cooling-water pump outlet to the block-side temperature-sensing valve. The head side temperature sensing valve is responsive to the temperature of the cooling water flowing into the head cooling water passage, and when the cooling water temperature is above a predetermined value, the head side cooling water is Establishing communication between the passage and the cooling water inlet of the head internal cooling water passage, and cutting off communication between the head side cooling water passage and the cooling water inlet of the head internal cooling water passage when the cooling water temperature is not above a predetermined value. However, the temperature-sensitive valve on the block side is sensitive to the temperature of the cooling water introduced into the cooling water passage within the block, and when the temperature of the cooling water is above a predetermined value, the cooling water in the cooling water passage on the block side and the cooling water passage within the block is controlled. The internal combustion engine is characterized in that when communication with the inlet is established and the temperature of the cooling water is not above a predetermined value, communication between the block-side cooling water passage and the cooling water inlet of the internal cooling water passage is cut off. Engine cooling system.
