  • Publication number: 20160376977
    Abstract: A cooling apparatus includes a coolant circulation channel for returning a coolant that passes through an engine main body, after causing the coolant to exchange heat with a radiator, device(s) and a heater, respectively. A multifunction valve as a rotary valve that is capable of adjusting an amount of coolant that is circulated to the radiator, device(s) and heater, respectively, is disposed in the coolant circulation channel. When automatic stopping of the engine is performed by idle stop-start control, during the automatic stopping the control apparatus continues to execute valve control of the multifunction valve that is being executed during the operation before the start of the automatic stopping.

  • Publication number: 20160348567
    Abstract: A change in a valve opening degree from an opening degree (a) to an opening degree (d) is caused by a decrease in a radiator outlet water temperature, and at such time a flow rate through a radiator enters a boiling region. Therefore, when such entry is predicted, a target engine outlet water temperature is forcedly changed from 105° C. to 100° C. Thereupon, the valve opening degree is changed from the opening degree (a) to an opening degree (f). The flow rate through the radiator when the valve opening degree is the opening degree (f) is greater than the flow rate through the radiator when the valve opening degree is the opening degree (d), and furthermore, the flow rate through the radiator does not enter the boiling region while the valve opening degree is changing from the opening degree (a) to the opening degree (f).

  • Patent number: 9506854
    Abstract: Light irradiates one light incident position on the surface of a scattering-absorption body. The light that propagates through the interior of the scattering-absorption body is detected at one light detecting position on the surface of the scattering-absorption body. On the basis of a light detection signal, a temporal profile of the light intensity of the detected light is acquired, and on the basis of the temporal profile, an mean optical path length of the light in the interior of the scattering-absorption body and information relating to the amount of substance to be measured in a region to be measured are calculated. The information relating to the amount of substance to be measured is corrected on the basis of the mean optical path length, such that the longer the mean optical path length, the greater the amount of substance to be measured is.

  • Patent number: 9470169
    Abstract: An object of the present invention is to enhance precision of air-fuel ratio control after return from fuel cut in a control device for an internal combustion engine that has a plurality of fuel injection modes, and performs calculation of a fuel injection amount by a method corresponding to an injection mode in use. For this object, the control device for an internal combustion engine the present invention provides normally determines the injection mode in response to an operation state, but designates a specific injection mode with a higher priority than the injection mode determined in response to the operation state at a time of return from fuel cut. For a predetermined time period after the return from fuel cut, the control device prohibits the injection mode from being changed in response to the operation state, and keeps fuel injection according to the designated specific injection mode.
