摘要： A coolant pump includes a pump frame, a driving wheel driven by an engine, a pump wheel driven by the driving wheel, and a clutch which couples the driving wheel with the pump wheel. The clutch comprises a friction surface arranged at the driving wheel, and a clutch disc which corresponds to the friction surface. The clutch disk is connected with and co-rotates with the pump wheel, and is axially shiftable between an engaged and a disengaged position. An axial pretension spring pretensions the clutch disc into the disengaged position. A permanent magnet forces the clutch disc into the engaged position. An electromagnet, when energized, generates a polarization which is opposite to a polarization of the permanent magnet to reduce a total magnetic attraction force of the permanent magnet with respect to the clutch disc and to thereby push the clutch disc into the disengaged position via the pretension spring.

摘要： A fan coupling device 1 connecting an internal combustion engine 31 to a cooling fan 21 comprises an input shaft 3 driven to rotate by the engine 31, a fluid coupling 12 that transmits torque from the input shaft 3 to the cooling fan 21 via a fluid, and a solenoid valve 13 having a valve main body 18 that adjusts a fluid amount in the fluid coupling 12. A determination as to whether or not the valve main body 18 is stuck in a lifted position on the basis of a rotation speed of the cooling fan 21, is started after the elapse of a predetermined time following output of a signal for returning the valve main body 18 to a closed position, The sticking determination can be performed with a high degree of precision without being affected by variation in the rotation speed of the input shaft 3.

摘要： The present invention relates to a cooling system in a vehicle (1) powered by a combustion engine (2). The cooling system comprises a coolant pump (3) adapted to circulating coolant in the cooling system, and an expansion tank (12) which allows expansion of the coolant in the cooling system during operation. The cooling system has pressure-providing means (17-20) which make active pressurisation of the coolant in the cooling system possible close to at least one inlet to the coolant pump (3), and a control unit (21) adapted to receiving information which indicates when the pump starts and to activating said pressure-providing means (17-20) to create a positive pressure close to the inlet to the coolant pump (3) during a starting process of the pump.

摘要： A method for providing supplemental internal air cooling to a multi-cylinder internal combustion engine. The method involves deactivating the fuel injector to one cylinder for a predetermined time period or temperature decrease, based upon engine operating conditions, and then reactivating the fuel injector. This results in cool air being pumped through the fuel-deactivated cylinder by the reciprocating action of the piston therein, which air-cools the walls, piston, and head of that cylinder from the inside. In response to a controlling algorithm in an Engine Control Module, various of the engine fuel injectors may be deactivated and then reactivated sequentially to provide distributed cooling over the entire engine. The invention is especially useful for motorcycle engines having two or more cylinders when the motorcycles are used at low or stop-and-go speeds, such as in parades or other ceremonial functions.

摘要： A device suitable to detect and indicate a decrease in the flow of coolant which circulates within an engine consists of a body (1) wherein a vertical cavity (2) is formed, whose bottom is in communication with the cooling circuit through an inflow duct (3) and an outflow duct (4), a float (5) being free to move in the cavity (2). The decrease in the flow of coolant incoming through the duct (3) causes an immediate lowering of the float (5) and therefore the activation of a sensor (10) which promptly indicates the problem by turning on an optical and/or acoustical signal. Preferably, the float (5) is provided at its lower end with a permanent magnet (9), and the sensor (10) is a magnetic reed switch placed in the body (1) beneath the cavity (2).
