Abstract

PURPOSE:To determine the volume of a canister to be enough size to satisfy a demand, and to protect the canister against a stone hopping during running. CONSTITUTION:In an automobile where an engine 4 and a transmission 5 are mutually connected, and a braking booster 6 is arrangedly provided near them, a section enclosed by a distributer 12 protruded in an engine side part, the transmission 5 and the braking booster 6 is arrangedly provided with a canister 13, which is attached to a dash panel 3. Since the canister 13 is hitherto arrangeclly provided in a place having large possibility to turn into a dead space, its volume can be determined to be enough size to satisfy a demand, and since enclosed by various equipment, it can be protected against a stone hopping during running.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a canister used for absorbing gasoline vapor in an automobile.

[0002]

2. Description of the Related Art In automobiles, a canister is used so that gasoline, which is a fuel, evaporates from a fuel tank or a carburetor so that the gasoline is not diffused into the atmosphere. This canister is usually provided inside the engine room. This will be described with reference to the drawings.

In FIG. 3, reference numeral 1 is a front body line of an automobile, and the inside is an engine room 2. Reference numeral 3 is a dash panel that partitions the engine room 2 and a vehicle compartment (not shown). An engine 4 and a transmission 5 are provided so as to be coupled to each other inside the engine room 2, and a brake booster 6 is disposed in the vicinity thereof. The engine 4 is supported laterally with respect to the vehicle body. Reference numeral 7 is a cylinder head, 8 is an intake manifold, and 9 is an exhaust manifold.

The engine 4 and the transmission 5 coupled to the engine 4 are located substantially in the center of the engine room 2, a radiator 10 is provided in front of the engine room 2, and the brake booster 6 is provided on the rear side of the transmission 5 side. The master cylinder 11 is located. Reference numeral 12 is a distributor that projects laterally from the body of the engine 4, and 13 is a canister that is attached to the dash panel 3 with a bracket 14.

In the conventional arrangement having such a structure, the canister 13 is located at a position surrounded by the main body of the brake booster 6 and the master cylinder 11, and the transmission 5 is located further below. Will be received.

[0006]

By the way, in recent automobiles, the engine room and the like are narrowed in spite of having a large passenger compartment, so that a comfortable riding space can be obtained without increasing the overall length of the vehicle body. . Due to the design, the height of the engine room is getting lower. On the other hand, from the viewpoint of ensuring the health of residents near the road and protecting the environment, the wind hits automobiles strongly, and regulations on not only the components of exhaust gas but also the components and amount of vaporized gas from fuel tanks have been tightened. Therefore, a large canister will be used, but there is a limit in that because the engine room is becoming smaller as described above.

Therefore, it is necessary to devise a place for arranging the canister. The present invention has been made in view of this point. Canister mounting structure, especially bracket shape,
As a prior art regarding the configuration, there is one described in Japanese Utility Model Laid-Open No. 63-28029, but this technology is different from the present invention, and since the canister is attached to the frame of the truck, the purpose of the present invention is Not along.

[0008]

As a means for solving the above-mentioned problems, the present invention provides a vehicle in which an engine and a transmission are combined and a brake booster is arranged in the vicinity of the engine and a side portion of the engine. A canister is disposed in a portion surrounded by the projected distributor, the transmission, and the brake booster, and the canister is attached to a vehicle body side member.

[0009]

With this structure, the portion surrounded by the distributor protruding toward the engine side, the transmission, and the brake booster often becomes a dead space. Therefore, by arranging the canister there, Therefore, the volume of the canister can be made necessary and sufficient. Further, since the canister is surrounded by the distributor, the transmission and the brake booster, the canister can be protected from flying stones and the like during traveling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 is the front body line of the car, and the inside is the engine room 2. Reference numeral 3 is a dash panel that partitions the engine room 2 and a vehicle compartment (not shown). An engine 4 and a transmission 5 are provided so as to be coupled to each other inside the engine room 2, and a brake booster 6 is disposed in the vicinity thereof. Engine 4
Is supported horizontally with respect to the vehicle body. Reference numeral 7 is a cylinder head, 8 is an intake manifold, and 9 is an exhaust manifold.

The engine 4 and the transmission 5 coupled to the engine 4 are located substantially in the center of the engine room 2, a radiator 10 is provided in front of the engine room 2, and the brake booster 6 described above is provided on the rear transmission 5 side. The master cylinder 11 is located. Reference numeral 12 is a distributor that projects laterally from the body of the engine 4.

A canister 13 is arranged in a portion surrounded by the distributor 12, the transmission 5, and the brake booster 6 which are projected to the side of the engine.
The canister 13 is attached to the dash panel 3 which is a vehicle body side member by a bracket 14. Illustration of pipes from the fuel tank and the carburetor (not shown) to the canister is omitted.

Even in the present invention having such a canister mounting structure, the function originally possessed by the canister is no different from the conventional one. However, because the canister is placed in a place that was apt to become a dead space in the past, it is possible to make the size sufficiently large and to stably absorb gasoline vapor over a long period of time. You will be able to

[0014]

Since the present invention has the canister mounting structure configured as described above, the portion surrounded by the distributor protruding toward the engine side, the transmission and the brake booster becomes a dead space. Since it is often the case, by arranging the canister here, the volume of the canister can be made necessary and sufficient. Further, since the canister is surrounded by the distributor, the transmission and the brake booster, the canister can be protected from flying stones and the like during traveling.
