[Detailed description of the invention] [Field of industrial application] This invention relates to an internal combustion engine auxiliary equipment cover, and in particular, covers the auxiliary equipment attached to the internal combustion engine by using a part of the bulkhead that partitions the engine room and the passenger compartment. The present invention relates to a protective internal combustion engine auxiliary equipment cover.

[Conventional technology]

In an automobile using an internal combustion engine as a driving source, an engine compartment 4 and a vehicle compartment 6 provided in a vehicle body 2 are separated by a partition wall 8, as shown in FIGS. Third
As shown in the figure, the internal combustion engine 10 in the engine room 4 includes:
An auxiliary machine, such as a generator 14, is attached by first and second supports 16 and 18. This generator 1
4 is surrounded by a protective cover 32. That is, the protective cover 32 has one end fixed to the first support 16 and the other end fixed to the generator 14.
is extended to the lower surface side of the generator 14 to surround it, and prevents rainwater and muddy water (indicated by a two-dot chain line) from below the vehicle body 2 from scattering toward the generator 14 side. Also,
As shown in FIG. 4, the generator 14 is attached to the upper part of the internal combustion engine 10 by first and second supports 16 and 18, and the protective cover is omitted. That is, the generator 14 is arranged at a high location where rainwater and muddy water (indicated by a two-dot chain line) from below the vehicle body 2 do not reach.
Further, a structure in which a cover is attached to a part of an internal combustion engine is disclosed in, for example, Japanese Utility Model Publication No. 57-52329. The structure described in this publication includes a cover that forms a timing belt chamber, a cold air introduction hole and a hot air exhaust hole are formed in this cover, and the hot air exhaust hole and the air inlet of the alternator are communicated through a pipe. , which prevents heating of the timing belt and extends the service life of the timing belt.

[Problem that the invention attempts to solve]

However, in the structure shown in FIG. 3, it is necessary to separately provide the protective cover 32, which has the disadvantage of increasing the number of parts, complicating the configuration, increasing the number of assembly steps, and increasing the cost. . Moreover, since the generator 14 is needlessly surrounded by the protective cover 32, the cooling effect of the generator 14 itself cannot be expected, and the function of the generator 14 is deteriorated due to heating, resulting in a shortened service life. There is an inconvenience that this happens. Furthermore, since the protective cover 32 is installed between the generator 14 and the partition wall 8, the generator 14 and the partition wall 8
Since it is necessary to form a predetermined space between them, the space occupied by the engine room 4 becomes larger, resulting in a larger size, and the cabin 6 cannot be made larger.
There was an inconvenience that the vehicle body space could not be used effectively.

In addition, in the structure shown in FIG. 4, since the generator 14 is mounted on the upper part of the internal combustion engine 2, the overall height increases, and as mentioned above, the space occupied by the engine room 4 increases, resulting in a larger vehicle. Due to factors such as the inability to make the chamber 6 large, there is an inconvenience in that the vehicle body space cannot be used effectively, and there is also an inconvenience in that the function of the generator 14 is likely to deteriorate due to high-temperature engine heat from the internal combustion engine 2. .

[Purpose of invention]

Therefore, the purpose of this invention was to eliminate the above-mentioned disadvantages and to reduce the number of parts and simplify the configuration by using part of the bulkhead that separates the engine room and the passenger compartment as a member to prevent contamination of the auxiliary equipment. At the same time, it is an object of the present invention to realize an internal combustion engine auxiliary equipment cover that can reduce assembly man-hours, reduce the space occupied in the engine room, and maintain the functions of the auxiliary equipment well.

[Means for solving problems]

In order to achieve this purpose, this invention provides an auxiliary machine attached to an internal combustion engine close to a partition wall that partitions an engine room and a vehicle compartment, and extends the partition wall to the lower surface side of the auxiliary machine, and A part of the auxiliary machine is used as a contamination prevention member.

[Effect]

According to the configuration of this invention, rainwater and muddy water from below the vehicle body are blocked by the anti-fouling member using a part of the partition wall, thereby preventing the function of the auxiliary equipment from deteriorating due to fouling. Further, since there is no need to separately provide a protective cover for the auxiliary equipment, the number of parts is reduced, the configuration is simplified, and the number of assembly steps is reduced. Furthermore, since the auxiliary equipment is not surrounded as would be the case with a protective cover, the auxiliary equipment itself receives a cooling effect, preventing the functionality of the auxiliary equipment from deteriorating due to heat damage, and extending the service life of the auxiliary equipment. Lengthen. Furthermore, the space occupied by the engine room is reduced to make the engine room more compact, and the cabin space is enlarged, thereby making effective use of the vehicle body space.

[Example of idea]

Embodiments of this invention will be described in detail and specifically below based on the drawings.

Figures 1 and 2 show an embodiment of this invention. In the figure, 2 is a vehicle body, 4 is an engine room, and 6 is a vehicle compartment. The engine room 4 and the vehicle compartment 6 are separated by a partition wall 8. Further, the engine room 4 accommodates an internal combustion engine 10 and has an upper portion covered by a front board 12.

The internal combustion engine 10 is attached with, for example, a generator 14, which is an auxiliary machine of the internal combustion engine 10. That is, the generator 14 is disposed on the side surface of the central portion of the internal combustion engine 10 on the side of the partition wall 8 with a slight spacing therebetween, and the upper part is supported by the first supporter 16 and the lower part is supported by the second supporter 18. It is supported. Further, a predetermined small distance C is formed between the outer circumferential surface 14a of the generator 14 and the outer portion 8a of the partition wall 8. That is, this distance C is a predetermined distance that can prevent the generator 14 from colliding with the partition wall 8 even if the generator 14 vibrates, and also prevents the generator 14 from colliding with the partition wall 8 during installation and removal work or maintenance inspection work. The minimum distance is ensured.

The partition wall 8 connects the generator 14 from the outer part 8a.
The generator 14 is located on the lower surface side of the engine, that is, on the internal combustion engine 10 side.
The generator 14 is curvedly extended along the outer surface shape of the generator 14.
It has a protruding top portion 8b at a position substantially directly below.
Further, a stain prevention portion 8c is formed on the partition wall 8 so as to be continuous with the protruding top portion 8b. This stain prevention part 8c is
This prevents rainwater and muddy water from below the vehicle body 2 from scattering toward the generator 14 side, and is configured to bounce rainwater and muddy water (indicated by a two-dot chain line) and flow it away below the vehicle body 2.

The operation of this embodiment will be explained below.

Rainwater and muddy water coming from below the vehicle body 2 collides with the stain prevention portion 8c of the partition wall 8, bounces off, and flows away below the vehicle body 2 again. This allows rainwater and muddy water to flow into the generator 1.
Since the generator 14 is not scattered to the 4 side, the generator 14 is prevented from being contaminated by rainwater or muddy water, and the function of the generator 14 is maintained well. In addition, a conventional generator 14
Since the generator 14 is not surrounded as in the case where a protective cover is provided, the generator 14 itself receives a cooling effect and is arranged at a certain distance from the internal combustion engine 10. Therefore, it is possible to prevent the functionality of the generator 14 from deteriorating due to self-heating of the generator 14 or heat damage from engine heat, and the service life of the generator 14 can be extended.

Further, the partition wall 8 and the stain prevention member can be shared,
Since there is no need to separately provide a protective cover for the generator 14, the number of parts can be reduced, the configuration can be simplified, the number of assembly steps can be reduced, and the cost can be reduced. Furthermore, by eliminating the need for a protective cover for the generator 14 and arranging the generator 14 close to the bulkhead 8, the space occupied by the engine room 4 is reduced and the engine room 4 is made more compact. The vehicle body space can be effectively utilized by increasing the size of the chamber 6.

In this embodiment, the anti-fouling portion 8c is formed to protect the generator 14, but the anti-fouling portion may also be formed on the partition wall to protect other auxiliary equipment such as exhaust purification equipment and pumps. It is possible.

[Effect of idea]

As is clear from the above detailed explanation, according to this invention, a part of the bulkhead that partitions the engine room and the vehicle compartment is used as a contamination prevention member for the auxiliary equipment, so that the bulkhead and the contamination prevention member can be used in common. Since there is no need to separately provide a protective cover for the machine, the number of parts can be reduced, the configuration can be simplified, the number of assembly steps can be reduced, and the cost can be reduced. In addition, since the auxiliary equipment is not needlessly surrounded as would be the case with a protective cover, the auxiliary equipment itself receives a cooling effect, preventing the functionality of the auxiliary equipment from deteriorating due to heat damage, and preventing the use of the auxiliary equipment. Can extend lifespan. Furthermore, the engine room can be made more compact by reducing the space occupied by the engine room, and the vehicle body space can be effectively utilized by increasing the cabin space.
