摘要： The present invention relates to a cooling device of internal combustion engine for vehicle and a control method thereof. The cooling device according to the present invention includes: an electric water pump; a bypass line bypassing a radiator; and a flow rate control valve for controlling a flow rate of cooling water circulating through the bypass line. During a low external air temperature state where the external air temperature is below a threshold, the cooling device increases the temperature of the cooling water by increasing the flow rate of the cooling water circulating through the bypass line as compared to during a high external air temperature state where the external air temperature is above the threshold, and increases a circulation flow rate of the cooling water by increasing a discharge flow rate of the electric water pump as compared to during the high external air temperature state.

摘要： A coolant circulation system includes a coolant circuit including a water jacket, a motor-driven pump, an outlet liquid temperature sensor, and a controller. The controller executes variation determination control for driving the motor-driven pump to determine whether a variation in the temperature of the coolant in a diesel engine is equal to or less than a predetermined value based on an outlet temperature detected by the outlet liquid temperature sensor. The controller executes circulation stop control on condition that it is determined that the variation in the temperature of the coolant is equal to or less than the predetermined value. The controller changes the period during which the circulation stop control is executed in accordance with the outlet liquid temperature detected at the start of the circulation stop control.

摘要： In an aspect, an electromechanical apparatus is provided, comprising an electromagnet, a magnetically permeable rotor, a drive, a current source, a current sensor and processing logic. The electromagnet includes a magnetically permeable housing and a wire coil disposed therein. The rotor spins and is disposed in the path of a magnetic circuit generated by the electromagnet. The drive rotates the rotor relative to the electromagnet housing. The rotor and electromagnet housing vary the reluctance therebetween as the rotor rotates. The current source applies a current to the electromagnet coil, wherein, during rotation of the rotor, fluctuations in the current result in the electromagnet coil due to the aforementioned varying reluctance are superimposed on the applied current. The current sensor senses fluctuations in current in the electromagnet coil. The processing logic reads the sensed current and determines the frequency of the fluctuations, which are correlated to rotor speed.

摘要： A coolant circuit is provided for an internal combustion engine having a compression machine for intake air. The coolant circuit includes a high-temperature circuit and a low temperature circuit. The high-temperature circuit is provided in order to cool the internal combustion engine by way of a coolant radiator and a first coolant pump arranged in the high-temperature circuit. The low-temperature circuit is provided with a second coolant pump in order to cool the intake air compressed by the compression machine by way of an intercooler and in order to cool a coolant of a coolant circuit in a condenser. The high-temperature circuit and the low-temperature circuit are cooling circuits which are separated from each other. The thermal base load of the low-temperature circuit is reduced by this design, whereby the pressure level in the coolant circuit can be reduced resulting positively in a reduction of the energy consumption.

摘要： A water pump includes an impeller, a whirl chamber, a pump body including the impeller and the whirl chamber, a cover case portion and a gasket portion being positioned between the pump body and the cover case portion. The cover case portion is formed with an inlet flow passage in which a fluid is introduced to the whirl chamber and an outlet flow passage in which the fluid is discharged from the whirl chamber. The gasket portion is formed with an inlet hole opening from the whirl chamber to the inlet flow passage and an outlet hole opening from the whirl chamber to the outlet flow passage. The gasket portion includes a portion covering at least one of the inlet flow passage and the outlet flow passage in a state where the portion of the gasket portion is exposed by not being in contact with the pump body.

摘要： A control apparatus for an internal combustion engine that includes an intercooler and an electrically driven water pump configured to circulate cooling water so as to flow through the intercooler is configured to calculate a required intercooler cooling efficiency ηreq obtained by dividing a difference between a cooler inflow gas temperature Tgin and a cooler outflow gas temperature Tgout by a difference between the cooler inflow gas temperature Tgin and a cooling water temperature Tw. A required circulation flow rate Qwreq is calculated based on the required intercooler cooling efficiency ηreq and a cooler passing-through gas flow rate G. The electrically driven water pump is driven so that a cooling water flow rate Qw approaches the required intercooler cooling efficiency ηreq.
