  • Publication number: 20240337420
    Abstract: A heat pump system includes a heat pump cycle, a heating unit, a low-temperature side heat medium circuit, and a control unit. The heat pump cycle includes a compressor, a condenser, and an evaporator. The heating unit heats ventilation air with heat released form refrigerant in the condenser. The low-temperature side heat medium circuit circulates a low-temperature side heat medium such that the refrigerant in the evaporator absorbs heat of the low-temperature side heat medium, and includes a heat source device and a heat amount adjustment unit. The control unit causes an amount of heat transfer in the heating unit for heating the ventilation air to approach a predetermined target value via adjustment in temperature of the low-temperature side heat medium by controlling a rotation speed of the compressor and an operation of at least one of the heat source device and the heat amount adjustment unit.

  • Patent number: 9353695
    Abstract: A control device acquires various requests concerning the performance of an internal combustion engine and sets a request-specific constraint on a control amount value. The constraint is expressed as a set of constraint index values assigned to individual control amount values, and the distribution of the constraint index values is varied in accordance with the type of a request. The control device integrates the constraint index values for each control amount value and then, in accordance with the distribution of the integrated constraint index value for a control amount, determines a limitation of the control amount. The control device determines a target control amount value within the limitation and controls the internal combustion engine in accordance with the target control amount.

  • Publication number: 20140346111
    Abstract: In a seawater treatment method in which after seawater is coagulated by a coagulant and is processed by a solid-liquid separation treatment, an RO treatment is performed, RO feed water having a good water quality is obtained by a small addition amount of the coagulant, and by the RO treatment of the RO feed water, a stable RO treatment can be performed over a long period of time. In a seawater treatment method which is a pretreatment method performed prior to a membrane separation treatment of seawater, after a cationic organic flocculant and/or an inorganic coagulant is added to seawater to conduct a reaction, a coagulation treatment is performed by addition of an alkaline solution of a high molecular weight compound which has a phenolic hydroxide and which is insolubilized under a high salt concentration, and a solid-liquid separation treatment is then performed. Subsequently, this treated water is desalinated by a membrane separation treatment.

  • Patent number: 8515646
    Abstract: A control apparatus of an internal combustion engine capable of appropriately reflecting various requests relating to the performance of the internal combustion engine. Specifically, the control device of the internal combustion engine acquires various requests relating to the performance of the internal combustion engine, and sets restricted ranges of the value of the control variable in accordance with the details of the requests. At this moment, the control device temporally changes the set restricted ranges for specific requests associated with the time integral value of the control variable rather than the instantaneous value of the control variable. Subsequently, the control device determines a final restricted range on the basis of the overlap between the restricted ranges set for each request, and determines the target value of the control variable in the final restricted range.

  • Patent number: 8234853
    Abstract: A catalyst degradation determining method includes the steps of: controlling an upstream-of-catalyst air-fuel ratio occurring upstream of a first catalyst to an air-fuel ratio that is rich of a stoichiometric air-fuel ratio so that first and second catalysts store oxygen up to a maximum storage amount of oxygen. The method then includes the steps of controlling the upstream-of-catalyst air-fuel ratio to a first lean air-fuel ratio until an output of a downstream-of-first-catalyst sensor indicates a lean air-fuel ratio, and then to a second lean air-fuel ratio and that has a value that is determined in accordance with an oxidizing-reducing capability index value, until a time point when an output of a downstream-of-second-catalyst air-fuel ratio sensor indicates an air-fuel ratio that is lean.

  • Publication number: 20120185148
    Abstract: Disclosed is a control device that is used for an internal combustion engine and capable of making various requests concerning the performance of the internal combustion engine be reflected in a target control amount value while the requests need not be expressed in the form of a requested control amount value. The control device acquires various requests concerning the performance of the internal combustion engine and sets a request-specific constraint on a control amount value. More specifically, the control device expresses constraints to be set for control amount values as a set of constraint index values assigned to individual control amount values, and varies the distribution of the constraint index values assigned to the control amount values in accordance with the type of a request. Next, the control device integrates, for each control amount value, the constraint index values assigned to individual requests with respect to each control amount value.

  • Patent number: 7890242
    Abstract: Immediately after startup of the engine, secondary air is supplied by an air pump into each exhaust branch passage via a secondary-air supply passage. A pressure sensor is disposed in the secondary-air supply passage. An output voltage of the pressure sensor decreases as the battery voltage decreases. When the battery voltage is lower than a permissible voltage, the output value of the pressure sensor is inhibited from being used as an output value representing the pressure. Thus, atmospheric pressure can be accurately detected.

  • Publication number: 20100018189
    Abstract: A control system of an internal combustion engine includes: a pressure detecting mechanism detecting a pressure in a gas passage which is communicated with the engine; and a controller acquiring a reference pressure as the pressure which is detected immediately after the controller is actuated, and controlling an actuator of the engine based on the reference pressure. The controller is inhibited from acquiring the reference pressure as the detected pressure when the controller is re-actuated after the controller is reset due to a factor other than a turned-off operation of an ignition switch.
