ABSTRACT:
A plastic intake manifold assembly for an internal combustion engine, and a method for its production. The assembly is in the form of a hollow plastic structure composed of two housing pieces in which a resonance chamber cross section is formed by means of an insert in the housing interior. Mating surfaces on the housing pieces are bonded together, for example by friction welding or ultrasonic welding. The invention has the advantage that by using inserts of differing size, resonance chambers of different sizes can be produced without altering or modifying the housing pieces.
