However, in such a conventional technique, since the battery 8 and the air cleaner 9 in the engine room E are obliquely arranged,
The flow of the air A in the engine room E is bad, and the components in the engine room E cannot be efficiently cooled by the air A. Therefore, it is necessary to take measures to form a rubber component (for example, an engine mount) that is easily affected by heat with a heat-resistant material, which is disadvantageous in terms of cost.

Further, in order to avoid the influence of heat from the engine 1, it is necessary to provide the battery 10 with the cover 10.
This leads to an increase in the number of parts.

Further, since this vehicle is provided with the air conditioning unit 19 for the right-hand drive vehicle on the left side of the vehicle body, it is not possible to apply this structure to the left-hand drive vehicle as it is because of piping. Therefore, it is necessary to prepare separate pipes for the right-hand drive vehicle and the left-hand drive vehicle, resulting in an increase in the number of parts.

The present invention has been made by paying attention to such a conventional technique, and provides an engine room interior structure of an automobile capable of improving the air flow in the engine room and reducing the number of parts. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to FIGS.
It will be described based on. The same parts as those in the prior art are designated by the same reference numerals, and a duplicate description will be omitted. The description will be made in order for each feature of the structure.

Alignment of parts (see FIGS. 1 and 2): In this embodiment, the battery 23 and the air cleaner 24 are aligned in the front-rear direction with the battery 23 and the air cleaner 24 facing straight forward (front facing). Further, air inlets 25 are formed on the left and right sides of the front surface of the vehicle body. Therefore, the flow of the air A guided from the air inlet 25 to the air box 15 is improved, and the rubber-based parts (for example, the engine mount 26 in FIGS. 4 and 5) in the engine room E are more efficiently moved to the air A. Can be cooled to.

Installation of collecting tank (see FIGS. 1 and 4): A collecting tank 27 in which a washer tank portion 27a and a reservoir tank portion 27b are integrated is provided. Since only one part is required, the number of parts can be reduced.

Installation of straightening vanes (see FIGS. 1, 2, 3 and 4)
Ter):

Rectifying function of the rectifying plate: The rectifying plate 2 is provided on the inside of the battery 23 in the vehicle width direction and on the inside of the collecting tank 27 in the vehicle width direction.

An outward bent portion 31 is formed at the lower end of the right flow plate 29, and the bent portion 31 is attached to the upper surface of the side member 30. The flow of the air A is further improved by installing the straightening plates 28 and 29.

Heat-shielding function of straightening vane: Since the left-hand side straightening vane 28 is provided inside the battery 23 in the vehicle width direction, this straightening vane 28 functions as a heat-shielding plate and shuts off engine heat.
Therefore, the cover that covers the battery 23 can be eliminated, and the number of parts can be reduced accordingly.

Component holding function of the straightening vane: The battery 23 is placed on the tray 32, and the left straightening vane 28 holds a battery cable 33 connected to the battery 23 with screws 34. Further, the presence of the rectifying plate 28 can restrict the slack of the battery cable 33 inward. The air duct 35 is held by a bracket 36 attached to the left flow plate 28. The air duct 35 is provided straight along the front-rear direction and does not interfere with the good flow of the air A in the engine room E. Incidentally, 37 is an electrical equipment box, which is attached to the hood ridge 6 with screws 34. The collecting tank 27 is attached to the right flow plate 29 with screws 34. Also,
The bottom of the collecting tank 27 is also screwed onto the hood ridge 6

A harness 41 from the generator is also attached to the right side rectifying plate 29. Since the components such as the harness 41 can be attached to the straightening vane 29 in advance and the components can be attached to the vehicle body together with the straightening vane 29, it is advantageous in terms of workability of attaching the components.

Pipe shielding / cooling mechanism (see FIG. 6): Below the reservoir tank portion 27b of the collecting tank 27, a space S is formed between the hood ridge 6 and the space S. The pipe 38 and the cooler pipe 39 are held by the holder 40. Therefore, these pipes 38,
39 is hidden by the collecting tank 27, and the appearance in the engine room E is improved. Further, the pipes 38, 39 can be cooled by the air flowing in the space S.

Central arrangement of air conditioning unit (see FIG. 1): The air conditioning unit 42 of this embodiment is a blower unit part,
It has a structure in which the cooler unit and the heater unit are integrated. The air conditioning unit 42 is provided in the vehicle interior R at the center position in the vehicle width direction. Therefore, the cooler pipe 39 and the heater hose 43 extend from the center position of the dash panel 14 to the engine room E side, and can be shared by the right-hand drive vehicle and the left-hand drive vehicle. Therefore, it is not necessary to prepare separate pipes for the right-hand drive vehicle and the left-hand drive vehicle, and the number of parts can be reduced.

Inside the air box of the engine control unit
Position (see FIG. 1): The engine control unit 22 is arranged in the air box 15. A harness (not shown) from the engine 1 mounted in the engine room E can be connected to the engine control unit 22 by a connector. Therefore, the complicated wiring work after mounting the engine 1 in the engine room E is not necessary, and the productivity is improved.

Arrangement of the wiper motor in the air box (Fig. 1
Reference): The wiper motor 16 is also arranged in the air box 15. Therefore, as compared with the case where the wiper motor 16 is arranged in the engine room E as in the conventional case, there is more space in the engine room E, and the ABS actuator 17 and the master back 18 can be increased in size. The degree of freedom in layout of parts is also increased.

Assembly of resonators (see FIG. 2): In the air cleaner 24, in addition to the air filter 44 for cleaning air, a resonator 46 is assembled via a partition wall 45. Conventionally, the tubular resonator was extended from the air cleaner 24 to the vicinity of the fuel filter 47. However, in this embodiment, since the resonator 46 is assembled in the air cleaner 24, there is no interference between the fuel filter 47 and other parts, and the fuel filter 47 is eliminated. The mounting reliability of the filter 47 is improved.

Power steering direct connection (see FIG. 7): The power steering pump 48 and the staring gear 49 are directly connected by the high pressure hose 50.
Easy installation and removal of both. Therefore, the power steering pump 48 and the oil tank 13 associated therewith can be easily retrofitted, and the power steering related mounting workability is improved.
