摘要:
In an embodiment, conductance of electricity to a heating element (4) for heating a throttle valve (2) of an automobile engine and a peripheral section thereof is performed only during a period wherein this heating can be performed effectively. Specifically, a controller (53) receives an output signal from an air flow sensor (54), and when a quantity of intake air is equal to or less than a predetermined “intake air quantity criterion for heating”, conduction of electricity to the heating element (4) is carried out. Conversely, when the quantity of intake air is greater than this “intake air quantity criterion for heating”, conduction of electricity to the heating element 4 is prohibited.
