Method for coupling a manifold housing system
First Claim
1. A method for coupling a first molded flange of a manifold for providing combustion air and combustion fuel to a cylinder of a vehicular internal combustion engine to a second molded flange of an extension of the manifold, the method comprising:
- molding the first flange of the manifold and the second flange of the extension;
molding an alignment member integral with the second flange;
forming a first aperture in the first flange;
forming a second aperture in the alignment member;
positioning the first flange and the second flange such that the first aperture is generally aligned with the second aperture;
inserting a threaded insert in the first aperture and at least partially in the second aperture;
inserting a threaded fastener into the threaded insert such that the fastener is circumscribed by the insert and extends into the first flange and at least partially into the second flange.

Abstract
A field replaceable unitary manifold housing for providing combustion air and combustion fuel to an internal combustion engine is disclosed. The housing includes an air purification cavity having a spaced apart air intake and air discharge. The housing also includes a filter for purifying air disposed in the air purification cavity intermediate the air intake and the air discharge. The housing also includes a hollow elongate member having a first end coupled to the filter and a second end coupled to a plenum chamber for directing the air, the plenum chamber being integral with the air purification cavity. The housing also includes a plurality of channels, each channel integral with the housing and having a first end integral with the plenum chamber and a second end coupled to a cylinder head of the engine. The air intake induces air into the air purification cavity, the induced air is purified by the filter, the hollow elongate member directs the air from the filter to the plenum chamber, and the plurality of channels direct the air from the plenum chamber to the cylinder head.
