    Abstract: PROBLEM TO BE SOLVED: To restrain cold coolant in an insulating container from flowing into a cooling circuit immediately after start of an engine, and precisely recover a warm coolant used for next engine start in the insulating container without expensive and complex controls such as a switch control of a switch valve. SOLUTION: When warm cooling water in a warmth retaining container 14 in a heat accumulating circuit H is fed to a water jacket 5 prior to engine start, cold cooling water existing in a cooling circuit R is discharged to the heat accumulating circuit H by the warm cooling water, and accumulated in the insulating container 14. After the engine start, when the cooling water is circulated in the cooling circuit R by driving a water pump 6, flow of the cooling water from the water jacket 5 into the heat accumulating circuit H is banned by a check valve 21. Thereafter, when temperature of the cooling water in the cooling circuit R becomes a predetermined value, a thermostat 23 is opened and the warm cooling water in the cooling circuit R is fed into the heat accumulating circuit H via a connecting passage 22, and recovered in the insulating container 14.

    Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of unevenness in warming-up property among cylinders due to worsening of warming-up property in a predetermined cylinder when letting coolant in a heat storage vessel flow into a water jacket and suppress reduction of improvement effect of emission and fuel economy accompanying the unevenness. SOLUTION: Among supply passages 15 corresponding to each cylinder, passage area is small in the supply passages 15 of No. 1 cylinder and No. 3 cylinder having small length of flow passages from the heat storage vessel 14 to the supply passages 15 and passage area is large in the supply passages 15 of No. 5 cylinder and No. 7 cylinder having large length of flow passages. By setting passage area of each supply passage 15 in this way, difference in circulation resistance of cooling water flowing into the water jacket 5 caused by difference in flow passage length is compensated, and flow-in amount of cooling water in each cylinder becomes equal. For this reason, it is possible to suppress worsening of warming-up property because flow-in amount of cooling water into the water jacket 5 in the predetermined cylinder is reduced and suppress occurrence of unevenness in warming-up property among the cylinders.

    Abstract: PROBLEM TO BE SOLVED: To control the temperature of refrigerant flowing in an internal combustion engine to a suitable level while improving fuel economy, in the internal combustion engine having an electric pump circulating the refrigerant and an open/close valve opened/closed to flow the refrigerant therein from a heat radiator.
    SOLUTION: A thermostat 400 includes a temperature-sensitive part 410, a spring 420, a shaft part 430, a valve part 440, and a partition wall 450. The thermostat 400 is maintained in a closed state in an initial state, and becomes an opened state when cooling water from a heater core 300 not through a radiator exceeds a predetermined temperature. Upstream of a water pump 500 is directly connected to an outlet side of the thermostat 400. The water pump 500 is controlled by a control signal from the ECU. When the ECU determines that an engine outlet water temperature is abruptly increased, the rotational speed of the water pump 500 is controlled to circulate the cooling water while increasing/decreasing a flow rate without changing a total flow of the cooling water.

    Abstract: PROBLEM TO BE SOLVED: To secure recovered heat quantity by an exhaust gas heat recovery apparatus while preventing hunting action of an exhaust control valve.
    SOLUTION: The exhaust control valve 160 for changing over execution/stop of exhaust gas heat recovery by the exhaust gas heat recovery apparatus 150 is driven to open and close by a heat sensing actuator 300. The heat sensing actuator 300 is provided in an auxiliary cooling water pipe 530. The auxiliary cooling water pipe 530 is provided to restrict or shut off flow of circulated cooling water when a thermostat 220 is closed (engine cold time), and to make the circulated cooling water flow when the thermostat 220 opens (engine valve open time). Consequently, since the heat sensing actuator 300 opens and closes with interlocking with the thermostat 220, exhaust gas heat recovery can be executed through engine cold time without hunting of the exhaust control valve 160 with responding to fluctuation of cooling water temperature near an engine outlet corresponding to engine load.

    Abstract: PROBLEM TO BE SOLVED: To promote the warming-up of a catalyst and an internal combustion engine by controlling the opening/closing of a valve so as to vary the flow velocity distribution of exhaust gas flowing through an exhaust port. SOLUTION: The valve 500 is arranged in the exhaust port 300. By opening/closing the valve 500, the flow velocity distribution of the exhaust gas flowing through the exhaust port is varied. A heat insulation member 600 is provided on an upper portion of the inner peripheral surface 310 of the exhaust port 300. At the beginning of starting an engine 100, that is, during warming up the three way catalyst, the valve 500 is controlled to be closed so that the flow velocity of the exhaust gas flowing along the heat insulation member 600 may become larger than the case where the valve 500 is opened. After the warming-up of the three way catalyst is completed, and also during warming up the engine 100, the valve 500 is controlled to be opened. COPYRIGHT: (C)2006,JPO&NCIPI
