摘要： An exhaust gas recirculation system for an internal combustion engine is provided. The exhaust gas recirculation system includes: an EGR passage configured to connect an exhaust gas passage of the internal combustion engine with an intake air passage; an EGR cooling system arranged at the EGR passage; and a control device configured to control the EGR cooling system. The control device is configured to provide feedback control of the cooling efficiency of the EGR cooling system to cause the temperature of intake gas suctioned into a cylinder of the internal combustion engine to approach a target intake gas temperature. The control device is configured to more increase the amount of change of the cooling efficiency when the flow rate of EGR gas recirculated is less.

摘要： A control apparatus for an internal combustion engine that includes an intercooler and an electrically driven water pump configured to circulate cooling water so as to flow through the intercooler is configured to calculate a required intercooler cooling efficiency ηreq obtained by dividing a difference between a cooler inflow gas temperature Tgin and a cooler outflow gas temperature Tgout by a difference between the cooler inflow gas temperature Tgin and a cooling water temperature Tw. A required circulation flow rate Qwreq is calculated based on the required intercooler cooling efficiency ηreq and a cooler passing-through gas flow rate G. The electrically driven water pump is driven so that a cooling water flow rate Qw approaches the required intercooler cooling efficiency ηreq.

摘要： A controller for the hybrid vehicle compensates for a shortage of an engine output to a vehicle demand output by discharge electric power of a battery when the vehicle demand output is higher than an upper limit output of a target operating range, and charges the battery by an excess of the engine output to the vehicle demand output when the vehicle demand output is lower than a lower limit output of the target operating range. The target operating range is set to a low load side as a SOC of the battery is higher in a predetermined SOC range. Also, the controller controls an intake air temperature during stopping of the engine to a target intake air temperature when the hybrid vehicle is traveling with the engine stopped. The target intake air temperature is increased as the SOC is lower in the predetermined SOC range.

摘要： Provided is a control device for an internal combustion engine that includes an EGR device equipped with an EGR cooler bypass passage and a flow-rate-ratio control valve equipped with a valve disc and capable of controlling a flow rate ratio. The control device is configured, when an opening degree control execution condition is met, to execute a vibration reduction control for controlling the flow-rate-ratio control valve such that the opening degree of the valve disc becomes greater than or equal to a vibration reduction opening degree that is greater than a minimum opening degree within an opening degree control range of the valve disc. The opening degree control execution condition includes a requirement that a parameter (pulsation level value) that becomes greater when exhaust pulsation acting on the valve disc is greater is equal to or greater than a first threshold value.

摘要： A controller for the hybrid vehicle selects an engine as a power apparatus of the hybrid vehicle when a request load is higher than a threshold load, and selects ae motor as the power apparatus when the request load is equal to or lower than the threshold load. The controller sets the threshold load in accordance with a SOC of a battery, and decreases the threshold load as the SOC is lower in at least a predetermined SOC range. The controller controls an intake air temperature during stopping of the engine to a target intake air temperature by operating an intake air temperature variable system when the motor is selected as the power apparatus. The controller sets the target intake air temperature in accordance with the SOC, and increases the target intake air temperature as the SOC is lower in at least the predetermined SOC range.
