摘要:
A controller includes a forced-induction-device controlling section, an obtaining section that is configured to repeatedly obtain a temperature of the coolant in the intake-air cooling system, a determining section that is configured to determine whether the temperature obtained by the obtaining section is higher than or equal to a forced-induction limiting control starting temperature. On condition that the temperature of the coolant has risen to a value at which the determining section determines that the temperature obtained by the obtaining section is higher than or equal to the forced-induction limiting control starting temperature, the forced-induction-device controlling section starts a forced-induction limiting control to lower a forced-induction pressure In the forced-induction limiting control, the forced-induction-device controlling section increases an extent of limiting of the forced induction as the temperature obtained by the obtaining section becomes closer to the boiling point.

A thermoactuator easily installed in an object without compromising the operating characteristics of the thermo-element has an element case, containing wax that expands and contracts with changes in temperature; a supporting portion attached at one end to the element case by crimping, slidably supporting a shaft at another end; a cylindrical casing having an opening in one end, at least a portion of the supporting portion pressed through the opening in the one end of the cylindrical casing; and a flange expanding outward from the one end of the cylindrical casing, in which through-holes are formed for mounting the thermoactuator to an object to which the thermoactuator is to be attached. The element case is supported by one end of the supporting portion housed within the object to which the thermoactuator is to be attached and the casing is mounted on the object via the flange.

Methods and systems are provided for adjusting a dual grille shutter system based on engine operating conditions. A position of a first group of grille shutters may be adjusted by a motor in response to engine temperature, CAC temperature, and driving conditions. A position of a second group of grille shutters may be adjusted based on the position of the first group of grille shutters.

A system for controlling an aerodynamic shutter of a vehicle includes an ambient temperature estimation module that determines an ambient temperature. A shutter control module that determines whether to actuate the shutter based on the ambient temperature. The shutter control module also determines a predetermined period before selectively applying a predetermined torque value to the shutter. The predetermined period is selected based on the ambient temperature.
