Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an air cleaner device for a midship engine vehicle, and in particular, in a vehicle having a catalytic converter directly under a trunk room, the air cleaner is provided in the trunk room. About the car that did.

(Prior Art) In a passenger car or the like generally used conventionally, as shown in FIG. 3, it is common to provide an air cleaner 2 in an engine room 5 together with an engine 5a and its accessories. The air cleaner 2 is placed on or next to the engine 5a and is connected to the engine via a duct.

However, recent automobiles tend to have a smaller volume in the engine room, and in a so-called FF type passenger car of a horizontal engine type, a transmission is also housed in the engine room. As the performance becomes higher, the control device for each component and the like becomes complicated, the number of members housed in the engine room becomes very large, and the layout is difficult now.

Among the parts housed in the engine room described above, the air cleaner has a relatively large volume, and although it is required to efficiently arrange the air cleaner, if the conventional air cleaner arrangement method is adopted, It is necessary to increase the volume of the engine room, which has a drawback that it may affect the style of the automobile.

Further, in the case of a sports type automobile as shown in FIG. 4, the volume of the engine becomes larger as the performance of the engine becomes higher, and many accessory devices for the engine are provided. As the air cleaner device 2, a device having a large air filtering capacity and good performance and having a relatively large volume is used. Therefore, the ratio of the volume occupied by the air cleaner device 2 in the engine room 5 is also relatively large. It has become a thing. As described above, this is a great design constraint for sports-type automobiles that particularly emphasize style.

In the case of a midship engine vehicle as disclosed in Japanese Patent Laid-Open No. 60-82437, the engine portion is provided between the rear wheel and the driver's seat to supply air to the engine. Air cleaner 2 for
As in the case of conventional automobiles, it is housed in the engine compartment, and as the engine becomes higher in performance, the air cleaner has a high performance as shown in FIG. Must be used, which occupies a large amount of space in the engine room, which has the drawback of significantly constraining the layout of other devices.

Further, in this type of passenger car, the catalytic converter connected to the exhaust pipe of the engine is provided under the trunk room at the rear of the engine room due to the installation space, and thereby the trunk room is installed. There is a drawback that the inside is heated and becomes high temperature. That is, in this case, the trunk room 1
You will not be able to store luggage that is not desired to be heated inside.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned drawbacks of the conventionally used midship engine vehicle, by disposing an air cleaner device in the dead space outside the engine room, It is an object of the present invention to provide an air cleaner device for a midship engine vehicle that enables effective use of the volume of the vehicle and cooling of the luggage compartment.

(Means and Actions for Solving Problems) In the midship engine vehicle of the present invention, an air cleaner device is provided in the space defined by the quarter panel on the side of the trunk and the rear floor side. An air duct for intake is opened outside the vehicle, and a duct that penetrates a partition with the engine room is used to allow the engine to perform intake. Further, the air cleaner device of the present invention is not limited in its installation location as long as it is inside the luggage compartment, and the air cleaner device should be provided in a place where it does not interfere with the storage of luggage or other spare parts. Can be done.

Therefore, the air cleaner device of the present invention can make room in the engine room, and can effectively utilize the dead space in the trunk room, and the fresh air passing through the air cleaner device allows the air space in the trunk room to be improved. Thus, even if the trunk room is heated by the exhaust pipe of the engine, the catalytic converter, or the like, its influence can be reduced.

(Embodiment) The structure of the air cleaner device for a midship engine vehicle of the present invention will be described according to the illustrated embodiment. As shown in FIG. A room 5 is provided, and a trunk room 1 is provided behind it. The midship engine vehicle in the case of this embodiment shows a type of vehicle in which the engine is horizontally installed, but the engine may be vertically installed and the form thereof is not particularly limited.

The trunk room 1 of the mid-ship engine vehicle of the present invention is provided with an air cleaner device 2 on its side, and an end of an air duct 3 thereof is opened outside the trunk room 1 so as to suck in air from the outside of the vehicle. ,
The air purified by the air cleaner device 2 is configured to be supplied to the carburetor 7 of the engine 5 a via the duct 4.

Therefore, the air passing through the air cleaner device 2 of the present invention is sent to the engine after cooling the inside of the luggage compartment, and the inside of the luggage compartment is always cooled by fresh air. Become.

Further, the duct 4 for supplying air from the air cleaner device 2 of the present invention to the engine 5a is provided so as to pass through the rear floor partition panel 6 that partitions the engine room 5 and the trunk room 1, or other However, in that case, the duct 4 is piped in a state in which the trunk room can be hermetically sealed and the dust in the engine room is not affected. It is necessary.

Under the above-mentioned conditions, the place where the air cleaner device 2 of the present invention is installed is preferably a dead space in the trunk room 1 as shown in the figure. For that purpose, the trunk room as shown in FIG. It is preferable to provide it inside the quarter panel 8 on the side of 1 and on the rear floor side 9 at the end of the floor 10 and the space formed by the panel 8.

This portion is a dead space inside the luggage compartment 1, and is usually a place where other devices and members are not housed, and a relatively large space can be secured. Since it is also a place, for example, when the air cleaner device 2 of the type shown in the drawing is installed vertically, it does not interfere with the luggage and spare parts accommodated in the trunk room 1. Even if a large, high-performance device as shown in FIG. 4 is used as the air cleaner device 2, even if it reduces the space in the trunk room to a small extent, the effect thereof is very small. .

(Effect of the Invention) Since the air cleaner device of the present invention has the above-mentioned configuration, it is possible to effectively use the space in the engine room and also to make the engine room compact. The installation place in the luggage compartment is also a place that is not simply used as a dead space in a conventionally used automobile, and the space is effectively used. Furthermore, since the air cleaner is inside the luggage compartment, the air passing through the air cleaner exchanges heat to cool the inside of the luggage compartment and then is sent out to the engine, so the interior of the luggage compartment is always cooled by fresh air. As a result, the disadvantage of the mid-ship engine car that the trunk room becomes hot can be solved.

Further, in the conventional automobile, since the air cleaner device is provided at a position very close to the engine, the vibration of the engine is directly transmitted to the air cleaner device, and its resonance often causes noise. By adopting the device of the invention, it becomes possible to reduce the noise of the vehicle.

Further, since the air cleaner device of the present invention is provided at a position distant from the engine, dust and oil splash caused by the operation of the engine are prevented from being applied, thereby preventing the air cleaner device from being contaminated, Since it is not affected by such vibrations, its sealability is improved, and in addition to this, maintenance can be facilitated and its manufacturing cost can be reduced.
