摘要： PROBLEM TO BE SOLVED: To provide a temperature controller of an internal combustion engine capable of promoting the warmup of a catalyst and the internal combustion engine.
SOLUTION: An oil passage 902 in which an oil force-fed from an oil pump 900 flows is formed to pass between a pair of exhaust ports 500 adjacent to each other. A valve 904 controlling the flowing of the oil into the oil passage 902 is installed in the oil passage 902. An outflow passage 906 is connected to the oil passage 902 on the downstream side of the valve 904. The oil remaining in the oil passage 902 flows from the flow-out passage 906 to the outside of the oil passage 902, and is returned to an oil pan. The amount of the oil flowing out of the oil passage 902 is less than the amount of the oil flowing into the oil passage 902. At the initial period of the starting of the engine 100, namely, during the warmup of a three way catalytic converter 600, the valve 904 is controlled in a closed state. During the warmup of the engine 100, the valve 904 is controlled in an open state.

摘要： 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.

摘要： 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.

摘要： PROBLEM TO BE SOLVED: To promote warming-up of in an internal combustion engine at the start of the engine while preventing a partial boiling of an antifreeze liquid in proximity of an combustion chamber of the internal combustion engine even when a concentration of the antifreeze liquid varies.SOLUTION: A control device 91 promotes the warming-up for controlling a rotation speed of a pump 23 so that a discharge rate of the antifreeze liquid is restricted when a temperature of the antifreeze liquid θ is lower than an upper limit temperature θc. Moreover, the control device 91 calculates a primal temperature θb that becomes a higher one as a concentration of the antifreeze liquid Wd gets higher based on the concentration of the antifreeze liquid Wd, and updates the upper limit temperature θc so that the deviation between the upper limit temperature θc that is presently set, and the primal temperature θb is reduced.

摘要： 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.

摘要： 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.
