Problems solved by technology

The ambient temperature around the carbon tank is high, which will reduce the adsorption efficiency of the carbon tank to fuel vapor, and the nozzle of the carbon tank to the atmosphere is also near the engine compartment. Once the carbon tank fails, the fuel will overflow, posing a safety hazard
[0003] In order to improve safety, the carbon canister is placed in the fuel tank in the models represented by Toyota, and the carbon canister is integrated with the fuel pump. However, the integrated structure is complex and the manufacturing cost is high. If parts need to be replaced, the fuel tank needs to be disassembled and replaced. It is necessary to replace the oil pump and carbon tank assembly at the same time, which is inconvenient and expensive to maintain

Embodiment Construction

[0021] The present invention will be further described below in conjunction with drawings and embodiments.

[0022] like figure 1 , figure 2 , image 3 , Figure 7 As shown, the carbon tank 3 is arranged in the middle of the rear of the car, and is located below the body floor 4 , and the carbon tank 3 is located in the upwardly recessed groove of the body floor 4 . The carbon canister 3 is arranged horizontally and horizontally, and a platform 3a is arranged on the top surface of the canister 3 housing. Two draw-in slots 3b are arranged on the platform 3a in a left-right symmetrical manner, and between the two draw-in slots 3b There is a boss 3c, which is wedge-shaped.

[0023] like figure 2 , image 3 , Figure 4 As shown, the carbon tank 3 is connected to the vehicle body floor 4 through a bracket, and the bracket is composed of two major parts, a positioning bracket 1 and a positioning plate 2 . Wherein, the positioning bracket 1 is a "T"-shaped sheet structure, ...

Abstract

The invention discloses an installation structure for a carbon canister of a sedan. The structure comprises the carbon canister (3), wherein the carbon canister (3) is arranged at the middle position of the rear part of the sedan, is positioned below a body floor (4), is horizontally arranged and is connected with the body floor (4) through a bracket. By the structure, the oil vapor adsorption efficiency of the carbon canister can be effectively improved, the potential safety hazard is reduced, and the carbon canister is firmly installed, convenient to detach and quickly maintained and replaced.

Description

technical field [0001] The invention belongs to the technical field of cars, and in particular relates to a carbon canister installation structure on a car. Background technique [0002] The car fuel evaporation control system is an indispensable and important part of the car in order to reduce environmental pollution and reduce fuel consumption, and is being paid more and more attention by car manufacturers. As an important part of the fuel evaporation control system, the carbon canister is mostly installed vertically, so it can only be installed in the engine room or near the front longitudinal beam. The ambient temperature around the carbon canister is high, which will reduce the adsorption efficiency of the carbon canister to fuel vapor, and the nozzle of the canister to the atmosphere is also near the engine compartment. Once the canister fails, the fuel will overflow, posing a safety hazard. [0003] In order to improve safety, the carbon canister is placed in the fue...
