Abstract
The present invention provides a throttle body assembly for an internal combustion engine. The assembly includes an insert having an opening and opposing bores arranged transverse to the opening. The insert is constructed of a first material, preferably a metal such as aluminum or magnesium. A throttle shaft is supported by the bores and spans the opening. A throttle blade is disposed within the opening and secured to the shaft. Both the throttle blade and throttle shaft are preferably constructed from a metal so that the seal between the throttle blade and the insert remains dimensionally stable. A body defines an air passageway with the insert at least partially disposed within the body and aligned with the air passageway. The body is constructed from a second material different from the first material, such as a composite plastic. The body may be a portion of an intake manifold. Accordingly, the above invention provides a lighter, less expensive throttle body that provides an adequate seal between the throttle blade and the air passageway so that a metal throttle body is no longer required.
