- a position sensor 18 for detecting the open / close position of the control valve 16 is attached, and a sensor attachment boss portion 19 to which a pressure sensor (not shown) for detecting the intake pressure is attached is provided.
- a variable intake shutter actuator 20 for driving a variable intake shutter valve (not shown) for switching the effective intake pipe length is attached.
- a purge control valve boss portion 21 to which a purge control valve (not shown) is attached is provided on the outer peripheral portion of the intake branch 11.
- the intake manifold 10 Since the intake manifold 10 has a substantially C-shaped inner passage as described above, the intake manifold 10 has a lower surface in the vertical direction in an assembled state assembled to the cylinder head 12 and the cylinder block 13 which are engine bodies.
- the 22 side is largely curved in an arc shape as a whole.
- a support bracket 23 and a protrusion 24 that protrude downward from the curved lower surface 22 are provided.
- the support bracket 23 and the protrusion 24 are opposite to each other with respect to the center of gravity 25 located substantially at the center of the intake manifold 10 when viewed from the longitudinal direction L1 (see FIGS. 1 and 2). Has been placed.
- the support bracket 23 is formed integrally with a half-structured part 26 constituting the outer peripheral side of the lower left portion of the intake branch 11 in FIG. 4 and is an inverted triangle shape that tapers downward in the longitudinal direction L1. 1, and a reinforcing rib 28 is provided inside as shown in FIG. 1, and a fixing bolt 30 as a fixing tool is inserted into a flange portion at the lower end thereof. Bolt holes 29 as bosses are formed through. The fixing bolt 30 inserted through the bolt hole 29 is fastened to the cylinder block 13, whereby the support bracket 23 of the intake manifold 10 and the cylinder block 13 are fastened and fixed together. As shown in FIG.
- the upper side of the intake manifold 10 is fixed to the cylinder head 12 by a plurality of fixing bolts 31 different from the fixing bolt 30 described above.
- a branch opening 33 that forms a flange shape of the intake branch 11 is fixed to a side wall 12A on the intake side where the intake port of the cylinder head 12 opens by a plurality of fixing bolts 31.
- the branch opening surface 33A which is a mating surface with the side wall 12A, is a flat surface, and one end of the internal passages of the plurality of intake branches 11 that communicate with the intake ports is open to the branch opening surface 34A. is doing.
- the protrusion 24 is formed integrally with a half-structured part 32 that forms the outer peripheral side of the right side portion of the intake branch 11 in FIG. 4, and as shown in FIG. 2, the longitudinal direction L ⁇ b> 1 in the intake manifold 10. It is provided in two places on both sides of the.
- Each protrusion 24 protrudes downward in a tongue shape, and as shown in FIG. 3, pipes 34 and 35 through which the cooling water flows are fixed to these protrusions 24. .
- clips 38 and 39 holding two cooling water pipes 34 and 35 that connect the water outlet 36 of the cylinder head 12 and the cooler bracket 37 of the cylinder block 13 are fitted and fixed to each protrusion 24.
