Abstract

Disclosed is an intake apparatus for an engine transversely mounted within an engine compartment at a front of a vehicle. The intake apparatus comprises: an intake manifold made of a synthetic resin and disposed on a front side of the engine, the engine front side being a front side of the vehicle; and a fuel distribution pipe disposed between the engine and the intake manifold to extend in the cylinder row direction and capable of delivering fuel to respective cylinders of the engine; wherein the intake manifold has a protruding portion provided on a front surface thereof to protrude from the front surface in a vehicle forward direction, wherein the protruding portion is provided at a position capable of allowing a member disposed in front of the intake manifold to come into collision therewith in the event of a vehicle frontal collision.

First claim

1 . An intake apparatus for an engine transversely mounted within an engine compartment at a front of a vehicle in such a manner as to allow a cylinder row direction to be oriented in a vehicle width direction, comprising:
an intake manifold made of a synthetic resin and disposed on a front side of the engine, the engine front side being a front side of the vehicle; and a fuel distribution pipe disposed between the engine and the intake manifold to extend in the cylinder row direction and capable of delivering fuel to respective cylinders of the engine; wherein the intake manifold has a protruding portion provided on a front surface thereof to protrude from the front surface in a vehicle forward direction, the protruding portion being provided at a position capable of allowing a member disposed in front of the intake manifold to come into collision therewith in the event of a vehicle frontal collision.

2 . The intake apparatus as recited in claim 1 , wherein the intake manifold comprises: a plurality of intake pipes connected, respectively, to a plurality of intake ports of a cylinder head of the engine; a surge tank connected to respective upstream ends of the plurality of intake pipes and extending in the cylinder row direction; and an intake air introduction pipe capable of introducing intake air to the surge tank, and wherein the protruding portion is provided on a front surface of the surge tank.

3 . The intake apparatus as recited in claim 2 , wherein the protruding portion is provided on each of both sides of a central region of the surge tank in the cylinder row direction.

4 . The intake apparatus as recited in claim 2 , wherein the intake manifold is internally provided with a gas introduction passage capable of introducing gas to an upstream region of the intake air introduction pipe, the gas introduction passage being defined using, as a passage wall, a part of outer walls of the surge tank and the intake air introduction pipe, thereby forming a raised portion on the front surface of the surge tank and a front surface of the intake air introduction pipe in such a manner as to be raised from the respective front surfaces in the vehicle forward direction.

5 . The intake apparatus as recited in claim 4 , wherein the intake air introduction pipe is connected to a central region of the surge tank in the cylinder row direction, and wherein the raised portion is formed both on the front surface of the surge tank and the front surface of the intake air introduction pipe, along a position of the central region.

6 . The intake apparatus as recited in claim 1 , wherein the intake manifold comprises a rear divided segment on a near side with respect to the engine, and a front divided segment on a far side with respect to the engine, the front divided segment being set to have strength less than that of the rear divided segment.

7 . The intake apparatus as recited in claim 2 , wherein the intake pipes are fixed to the cylinder head, whereby the intake manifold is supported by the cylinder head in a cantilevered state.

8 . The intake apparatus as recited in claim 7 , which comprises a load-receiving member provided in a vicinity of the intake air introduction pipe to receive and stop the intake air introduction pipe during the vehicle frontal collision.
