    摘要： During engine warm-up, a flow regulating unit in a cooling system operates in a fuel efficiency priority mode. In this mode, a head-side cooling water flow rate (Qhd) is regulated to be equal to or smaller than a first upper limit; a block-side cooling water flow rate (Qbk) is regulated to be equal to or smaller than a second upper limit; and cooling water flowing out of a block-side passage and a head-side passage flows mainly into a bypass passage. When a heating request to heat blown air is made during engine warm-up, the regulating unit operates in a heating priority mode. In this mode, Qhd is regulated to be equal to or smaller than a third upper limit; Qbk is regulated to be equal to or smaller than a fourth upper limit; and at least cooling water flowing out of the head-side passage flows into a heat exchanger.

    摘要： A throttle valve control apparatus for internal combustion engine stabilizes the engine speed in idle operation by always correcting the full closing reference position in ISC using a single throttle valve. Signals of a neutral position signal, air conditioner signal, electrical load signal, accelerator position signal, engine speed, and water temperature are inputted to a CPU in an electronic control unit via an input circuit. The CPU calculates such a throttle opening as to make the actual speed of the internal combustion engine in idle operation equal to a target speed in idle operation stored beforehand, compares the throttle opening with preset upper limit value and lower limit value of the throttle opening in idle operation, and corrects the full closing reference position of the throttle opening on the basis of the result of comparison. As a result, the full closing reference position in the throttle opening of the throttle valve is always corrected.

    摘要： A throttle valve for an engine is disabled to be driven by an actuator by limiting a target throttle angle upper limit of a target throttle angle, when a failure is detected by an electronic control unit. Then, the target throttle angle is returned to a value used at a normal time at a restoration timing of a restoration of the system to a normal state or while the opening speed of a throttle valve at a restoration is being restrained. Thus, an abrupt opening operation of the throttle valve in response to the depression carried out by the driver on an accelerator pedal. Further, the throttle valve is driven in a limp-home operation mode by controlling the reduced number of operating cylinders of the engine. The reduced number of operating cylinders is increased or the operations of all cylinders are halted, when the engine speed rises above a predetermined value.
