  • Patent number: 10927747
    Abstract: A cooling system of an internal combustion engine includes an adjustment valve configured to adjust a flow rate of a cooling liquid discharged from a water jacket. A controller for the cooling system includes circuitry configured to execute flow-restriction control that controls the adjustment valve to restrict discharge of the cooling liquid from the water jacket, thereby increasing temperature of an engine body. The circuitry is configured to execute the flow-restriction control so that temperature of the cooling liquid in the water jacket at which the flow-restriction control is terminated is lower when an ambient pressure is low than when the ambient pressure is high.

  • Patent number: 10808597
    Abstract: An internal combustion engine includes a water jacket, a cooling water pump as a cooling liquid pump, and an adjusting valve. A control device for the internal combustion engine executes the water stoppage control of increasing the temperature of the engine body by limiting the discharge of the cooling liquid from the water jacket by the adjusting valve, and an automatic stop and automatic startup control of automatically stopping and automatically starting the internal combustion engine. The control device increases the fuel injection amount for automatically starting the internal combustion engine in a case where the water stoppage control is being executed when the internal combustion engine is automatically stopped as compared with a case where the water stoppage control is not being executed when the internal combustion engine is automatically stopped.

  • Patent number: 10619554
    Abstract: A coolant circuit of an engine cooling apparatus includes a first passage where coolant flows through a radiator and a second passage where coolant flows without passing through the radiator. A coolant control valve controls a first passage flow rate Frad and a second passage flow rate Fsec. An outlet coolant temperature sensor detects an outlet coolant temperature Tout, which is a coolant temperature before a branching point of the first passage and the second passage. An inlet coolant temperature sensor detects an inlet coolant temperature Tin, which is a coolant temperature after a merging point of the first passage and the second passage. A coolant temperature estimator calculates a radiator coolant temperature Trad, which is a coolant temperature at a coolant exit of the radiator, when the first passage flow rate Frad is greater than or equal to a specified flow rate using equation (1).
