TH52630B - Intake manifold for internal combustion engine - Google Patents

Abstract

The DC60 intake manifold M for the internal combustion engine has two or more structural components, P1 to P3, which consists of one structural assembly, P1, with rims provided. Extend inlet 22 into one section, with a throttle device 4 connected to it and an overhang at outlet 40 that will be attached to the cylinder head 2 where intake port 5 is provided. The first P1 structure, as such, provides a single, inlet 21 piece that makes Occurs as at least part of the passage that is Entrance 11 and is included with the overhang at Entrance 22.The overhangs at Exit 40 are arranged in the same section as Entrance 21 to provide Crossed with the direction in which the passage of entrance 11 extends the chest, two threaded bolts 451 and 452 are provided to secure the protrusion at outlet 40 to the cylinder head, on the straight side. Across each other of the path through the entrance. 11 The stiffness of the edge protrusions at the inlet and the fixation. The protrusion of the outlet hole and the cylinder head by means of bonding will improve the efficiency of Reduces vibration on throttle devices that are coupled to the inlet protrusions.The intake manifold M for the internal combustion engine has two or more structural components, P1 to P3, which include: First structural component, P1, whose rim is provided.
