Abstract

1423450 Intake manifolds DAIMLER-BENZ AG 2 Aug 1973 [3 Aug 1972] 36815/73 Heading F1B In an intake manifold having means to influence the oscillation of the air column as a function of engine speed the manifold comprises a single intake duct having a fixed cross-section and has an open air inlet aperture at a point intermediate its length. The intake pipe 16 projects into a collector 13 which is connected to an air filter 14 and has three slits 21 for which a ring 23 serves as an intake funnel. In the lower speed range the effective length L 1 generates resonant vibrations which assist charging; the vibrations being only negligibly disturbed by the slits 21. With increasing speed air is drawn in via slits 21 to reduce the effective length to L2 to produce resonant vibrations corresponding to the higher speed to thereby assist charging. In modifications the intake manifold (33), Fig. 3 (not shown) consists of first and second sections joined by a multiple-armed bracket mounted internally so as to provide a gap between sections. In further modifications one of the sections is shaped to form an inlet funnel (46), Fig. 6 (not shown).
