Abstract: In an electric water pump for circulating cooling water of an engine mounted on a vehicle or similar, a time interval to switch energized phase of a pump motor is set to longer than a time interval during a normal flow rate control (during a flow rate control at a flow rate equal to or more than a flow rate where an electromotive force generated at a non-energized phase is detectable). In the case where a pump discharge pressure (or a water temperature of the cooling water) repeatedly increases and decreases in this extremely low flow rate state, it is determined that the electric water pump normally rotates as required. This allows providing the extremely low flow rate state between a water stop state and a water circulation state in a control for stop of water in an engine cooling system.

Abstract: The disclosed internal combustion engine has an electric water pump and a water temperature sensor that detects coolant water temperature. An electronic control device stops the driving of the water pump when the coolant water temperature is lower than a baseline temperature. Meanwhile, the electronic control device drives the water pump in accordance with the coolant water temperature when the coolant water temperature is higher than the baseline temperature. When the driving of the water pump is stopped, the internal combustion engine forbids at least one engine control until the water pump is driven.

Abstract: When the passing of coolant in an internal combustion engine is restricted to accelerate the warm-up of the internal combustion engine and the coolant in this engine is undergoing nucleate boiling, the restriction of the passing of the coolant in the internal engine is maintained. Specifically, the restriction of the passing of the coolant in the internal combustion engine is maintained during nucleate boiling from the beginning of nucleate boiling of the coolant in the internal combustion engine until the maintenance period has elapsed. Thus, the warm-up of the internal combustion engine is effectively accelerated by restricting the passing of the coolant in the engine. Furthermore, the restriction of the passing of the coolant in the internal combustion engine is canceled when the maintenance period has elapsed. Thus, low-temperature coolant flows in the internal combustion engine and the internal combustion engine is cooled by this coolant, so nucleate boiling of the coolant in the engine is suppressed.

Abstract: Disclosed is a device for cooling an internal combustion engine in which circulation of cooling water is halted until the cooling water reaches a predetermined temperature, wherein decline in the durability of a radiator, which is caused by thermal strain that occurs when circulation of the cooling water is restarted and the cooling water is introduced into the radiator, is suppressed. An internal combustion engine (10) comprises an electric pump (23), a water temperature sensor (92), a radiator (21), and a thermostat (22). The water temperature sensor (92) detects a cooling water temperature (THW). The radiator (21) is capable of circulating the cooling water between the radiator (21) and an engine cooling system (13). If the cooling water temperature (THW) is equal to or greater than a valve opening temperature (TZ), the thermostat (22) opens and the cooling water is introduced into the radiator (21).
