An apparatus for adjusting the specific volume of intake air for an engine has an orifice for controlling the amount of air to by-pass a throttle valve. The apparatus is provided with a lattice-shaped heating element which is disposed on the downsteam side of the orifice. Thus, carbon and other substances which may flow back from the engine are trapped and burnt by the heating element.
