摘要： PROBLEM TO BE SOLVED: To provide a cooling system of an internal combustion engine capable of accurately detecting boiling of cooling water.
SOLUTION: This cooling system of an internal combustion engine circulates cooling water in a cooling water pipe conduit and inside the engine by using an electric water pump. A part of the cooling water pipe conduit is provided with a water level detecting means for detecting the water level of the cooling water. For example, the water level detecting means can be provided in a reserve tank for accumulating the cooling water. When the cooling water boils, the water level of the cooling water rapidly rises. A boiling detecting means detects the rising rate of the water level of the cooling water, and detects boiling of the cooling water based on the detected rising rate.

摘要： PROBLEM TO BE SOLVED: To reduce a difference of a cooling water temperature in an internal combustion engine, and to advance the warm up of the internal combustion engine, in regard to a cooling device for an internal combustion engine.
SOLUTION: This cooling device for the internal combustion engine comprises a cooling water passage for circulating cooling water to the internal combustion engine, a water temperature sensor for detecting the temperature of cooling water, a cooling water flow changing mechanism for changing the flow direction of cooling water in the cooling water passage, a control means for controlling the cooling water flow changing mechanism, and a memory means for storing the heater-and-blower operating water temperature. In the case that the temperature of cooling water detected by the water temperature sensor is lower than the heater-and-blower operating water temperature, the control means periodically changes the flow direction of cooling water through the cooling water flow changing mechanism. By this structure, in a starting warm-up process of the internal combustion engine, cooling water is circulated in a local range of the cooling water passage not over the whole of the cooling water passage. As a result, a difference of the cooling water temperature inside the internal combustion engine is reduced (namely, unified in the distribution of a temperature), and the early warm-up of the internal combustion engine is enabled.

摘要： PROBLEM TO BE SOLVED: To provide a cooling water controller of an internal combustion engine promoting the warmup of the internal combustion engine, sufficiently recovering exhaust heat, and suppressing the boiling of cooling water. SOLUTION: This cooling water controller comprises: a cooling water passage circulating between the internal combustion engine; an exhaust heat recovery device and a heater core; a bypassing passage; a flow distribution means; and a control means. The bypass passage is connected to the cooling water passage, and bypasses the internal combustion engine. The flow distribution means distributes the flow of the cooling water between a water jacket in the internal combustion engine and the bypass passage. The control means changes the ratio of the flow of the cooling water in the water jacket inside the internal combustion engine to the flow of the cooling water in the bypass passage. The warmup of the internal combustion engine is thereby promoted, the exhaust heat in the exhaust heat recovering device is sufficiently recovered, and the boiling of the cooling water is suppressed.
