When the battery moves to the auxiliary machine part side at the time of a side collision, contact with the resonator battery interposed between the battery and the auxiliary machine part to prevent the battery from colliding with the auxiliary machine part and protect the auxiliary machine part Can do.

  In addition, since the resonator is supported by the air cleaner via an elastic body that is compressible in the vehicle width direction, when the battery collides with the resonator, the shock received by the resonator is absorbed by the deformation of the branch portion of the intake hose and the elastic body And the resonator is protected to prevent its damage.

  Therefore, it is possible to protect parts such as auxiliary equipment and resonators in the engine room at the time of a side collision of the vehicle, and to reduce repair costs.

An output shaft (not shown) extends from the transmission 4 in the vehicle width direction. Auxiliary components such as a thermocap 5 and an EGR valve 6 are attached to the transmission side surface (left end surface) of the engine 3 so as to protrude above the transmission 4, and these thermocap 5 and EGR. A battery 7 is disposed in the engine room 2 with a space in the vehicle width direction from the valve 6.

  As shown in FIG. 2, an oil pan 9 is attached to the lower part of the cylinder block 8 of the engine 3, and a cylinder head 10 is attached to the upper part of the cylinder block 8. A head cover 11 is attached. An air cleaner 12 is disposed at the upper part of the engine 3, and as shown in FIG. 1, an intake manifold 13 including three intake pipes is attached to the vehicle rear side surface of the cylinder head 10.

  As shown in FIG. 4, a throttle body 14 is attached to the intake manifold 13, and the throttle body 14 and the air cleaner 12 are connected by a flexible intake hose 15. A resonator 16 is disposed between the air cap 12 and the battery 7 above the thermo cap 5 and the EGR valve 6 as auxiliary parts so as to cover the thermo cap 5 and the EGR valve 6 from above. Yes.

  Thus, as shown in FIGS. 1 and 4, the intake hose 15 protrudes toward the vehicle rear side of the thermo cap 5 and the EGR valve 6, which are auxiliary parts, and the intake hose 15 extends forward of the vehicle. An extending branch portion 15 a is formed, and this branch portion 15 a is connected to the resonator 16.

  The resonator 16 is formed such that an end portion on the front side of the vehicle extends to substantially the same position as the front end portion of the cylinder head 10, and the front end side portion thereof is mounted via a mount rubber 17 that is an elastic body that can be compressed in the vehicle width direction. In addition to being supported by the air cleaner 12, the lateral direction of the mount rubber 17, that is, the bottom portion in front of the battery 7 in the vehicle front-rear direction is supported by the engine 3 so as to be rotatable about the vertical axis by the mount rubber 18 constituting the support portion. ing. Specifically, as shown in FIG. 3, a mount rubber 17 is fitted to the side of the air cleaner 12, and a pin 19 protruding from the side of the resonator 16 is inserted into the center of the mount rubber 17. Thus, the front end portion of the resonator 17 is elastically supported by the air cleaner 12 via the mount rubber 17. As shown in FIG. 3, a bracket 20 made of sheet metal is attached to the cylinder head 10 of the engine 3, and projects from the bottom of the resonator 16 at the center of the mount rubber 18 fitted to the bracket 20. By inserting the pin 21, the front end bottom portion of the resonator 16 is elastically supported by the engine 3 so as to be rotatable about the vertical axis by the pin 21. Accordingly, the resonator 16 is elastically supported by the intake hose 15 and the mount rubbers 17 and 18 at three points.

  On the other hand, as shown in FIG. 2, an exhaust manifold 22 including three exhaust pipes is connected to the front surface of the cylinder head 10 of the engine 3, and the exhaust manifolds 23 are collectively connected to the catalytic converter 23. The exhaust pipe 24 extending from the catalytic converter 23 extends downward and is then bent at a substantially right angle toward the rear of the vehicle (the back side in FIG. 2) and extends toward the rear of the vehicle.

  In the intake device of the engine 3 configured as described above, the intake hose 15 is protruded to the vehicle rear side of the thermocap 5 and the EGR valve 6 which are auxiliary parts, and the branch extending to the intake hose 15 forward of the vehicle is provided. Since a large-sized resonator 16 is connected to the branching portion 15a and the end on the front side of the vehicle extends to substantially the same position as the front end of the cylinder head 10, as shown in FIG. When 7 moves to the thermocap 5 or EGR valve 6 side (left side in FIG. 5), which is an accessory part, the battery 7 comes into contact with the resonator 16 interposed between the battery 7 and the thermocap 5 or EGR valve 6. . This prevents the battery 7 from colliding with the auxiliary parts such as the thermo cap 5 and the EGR valve 6, and the auxiliary parts such as the thermo cap 5 and the EGR valve 6 are protected from the impact to prevent damage. It is. In particular, in the present embodiment, since the large resonator 16 is used, auxiliary components such as the thermo cap 5 and the EGR valve 6 are effectively protected by the resonator 16.

  Further, since the resonator 16 is supported by the air cleaner 12 via a mount rubber 17 which is an elastic body compressible in the vehicle width direction, when the battery 7 collides with the resonator 16 as shown in FIG. When the branch portion 15a and the mount rubber 17 are elastically deformed, the shock received by the resonator 16 is absorbed, and the resonator 16 is protected and its damage is prevented.

  Further, in the intake device for the engine 3 according to the present invention, the bottom portion of the front side in the vehicle longitudinal direction with respect to the battery 7 of the resonator 16 is supported by the engine 3 by the mount rubber 18 and the pin 21 so as to be rotatable around the vertical axis. Large vibrations in the vertical direction of the resonator 16 during traveling of the vehicle can be suppressed to prevent the resonator 16 from colliding with auxiliary parts such as the thermo cap 5 and the EGR valve 6.

  Further, as shown in FIG. 5, when the battery 7 collides with the rear portion of the resonator 16, the rear portion of the resonator 16 rotates about the vertical axis about the vertical axis about the mount rubber 18 and the pin 21 which are the front support portions. Therefore, the impact on the resonator 16 is absorbed, and the resonator 16 is effectively protected from the impact. In this case, since the pin 21 constituting the support portion that supports the bottom portion of the resonator 16 is arranged on the front side in the vehicle front-rear direction with respect to the battery 7, the impact load applied to the pin 21 can be suppressed low, and damage to the pin 21 can be prevented. It is.

  As described above, according to the air intake apparatus according to the present invention, the auxiliary parts such as the thermo cap 5 and the EGR valve 6 and the parts such as the resonator 16 in the engine room 2 are protected and repaired in the event of a side collision of the vehicle.
