US 8,464,689 B2 · Throttle body to intake manifold mounting

Abstract

At least one set of locator pins is provided on the flange of an intake manifold which couple with an orifice provided on the flange of a throttle body to align the two parts to ensure that they are properly oriented when assembled. In addition, through holes are provided on the throttle body flange and threaded inserts are provided on the flange of the intake manifold. The locator pins are coupled with the orifices prior to inserting a bolt through the through holes to engage with the threads of the threaded insert. By providing the locator pins, the two flanges are held in a desired orientation so that the ducts of the two flanges are properly aligned to substantially eliminate a step or mismatch at the interface.

Dependent claims

A throttle body-to-manifold coupling system, comprising:

a first flange coupled to the throttle body;
a second flange coupled to the manifold;
sets of locator pins extending outwardly from the second flange;
and
an orifice provided on the first flange for each set of locator pins wherein each set of locator pins and the associated orifice are arranged to couple when the manifold is assembled to the throttle body;
and
wherein the first flange has the sets of locator pins extending perpendicularly from a face of the first flange, the first flange defines a roughly central opening, and the sets of locator pins are asymmetrically arranged on a periphery of the second flange with respect to the opening.
