Abstract

PURPOSE:To facilitate an assembling operation, lower the cost and lower the weight by making a connecting duct between a resonator integrally formed on a wheel housing panel and an outer air intake passage pass through a hole provided on a front fender apron. CONSTITUTION:A resonator 11 has an extension duct portion 11a on which a connecting duct 10 is fittingly connected on an engine room 14 side. The connecting duct 10 is connected to the extension duct portion 11a through the hole 13a of a front fender apron 13, and a wheel housing panel 12 is fixedly installed on each lower portion of the front fender apron 13 with bolt/nut clamping means 19, 19, thereby simultaneously placing and fixing the resonator 11. Hence, any other parts, etc. for fixing only the resonator can be dispensed with, and further, as the wheel housing panel is installed in a large operating space, the resonator is also installed. Therefore, an assembling operation can be facilitated while lowering the cost and lowering the weight.

Description

[Detailed description of the invention] a. Industrial application field The present invention relates to an intake structure for an automobile engine.

b. Conventional technology and its problems Conventionally, there are automobiles in which a resonator is provided in the middle of an outside air intake passage that introduces outside air into the engine.

As shown in FIG. 5, such an automobile glue zoner l is installed independently near the front fender panel 2, so it occupies a dedicated installation space in a narrow space in the engine compartment 3. was.

As described above, since the resonator 1 is installed in a narrow space, the installation work is not easy, and a large number of other parts are required to install the resonator 1.
This resulted in increased cost and weight, and was also structurally weak.

In addition, in FIG. 5, 4 is a front bumper, 5 is an engine hood, 6 is a headlight, and 7 is a wheel housing panel.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an intake structure for an automobile engine that is easy to assemble, can reduce costs and weight, and is structurally strong. With the goal.

C9 Means for Solving Problems In the present invention, in order to achieve the above object, in the intake structure of an automobile engine that includes a resonator in the middle of the outside air intake passage, the resonator is integrally molded on the wheel housing panel. Also, an intake structure for an automobile engine, characterized in that a connection duct for communicating the resonator and the outside air intake passage passes through a hole provided in a front fender apron.

d. Example Hereinafter, an example of the intake structure for an automobile engine according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 show an embodiment of the present invention.

In the intake structure of this embodiment, a resonator 11 connected via a connecting duct 10 is located on the right wheel housing panel 12 in the middle of an outside air intake passage (not shown) that introduces outside air into the engine (not shown). It is integrally molded. Further, in accordance with this, a hole 13a is bored in the front I/fender apron 13, and a connecting duct 10 is inserted into the hole.
In particular, in this embodiment, the resonator 11 is formed slightly forward of the wheel housing panel 12 (see FIG. 4).

In addition, in Figures 1 to 4, 14 is the engine room, 15 is the front fender panel, 16 is the headlamp, 17 is the engine hood, 1st is the front bay/pa, 1
9 is the front wheel.

In this embodiment, the resonator 11 is an extended duct part to which the connecting duct NO is fitted and connected to the engine room 14 side!
, 1a.

The front fender apron 1 is attached to the extension duct part 11a.
3 is connected to the connecting duct 10 through the hole 13a, and the wheel housing panel 12 is connected to the front fender panel 1 by means of bolt fastening means 19.19.
5 and the lower part of the front fender panel 13, the resonator 11 is also positioned and fixed at the same time.

e. As described in detail, according to the intake structure for an automobile engine according to the present invention, the resonator is integrally molded on the wheel housing panel, and the connecting duct that connects the resonator and the outside air intake passage is provided at the front. Since it is configured to pass through a hole in the fender apron, there is no need for other parts to fix only the resonator, and the resonator can also be installed by installing the wheel housing panel in a large work space. Assembly work is easy, cost and weight can be reduced, and furthermore, since the wheel housing panel itself is no longer a unitary structure, it can also be made structurally stronger.
