Design and assembly structure of an automobile carbon canister

Abstract

A car canister design and assembly structure, which includes a body hub bag, a carbon canister, and an engine intake manifold. The car body wheel hub bag is provided with a carbon canister mounting bracket, the carbon canister is provided with a carbon canister mounting support, and the carbon canister is plugged in. Between the body wheel hub package and the engine intake manifold, it is fixed on the carbon canister mounting bracket and fixed with the carbon canister mounting support. The carbon canister is at the same height as the body wheel hub package and is located inside the longitudinal beam. This layout structure effectively solves the problem that the carbon tank is submerged by oil due to the low height of the carbon tank, and ensures the service life and working capacity of the carbon tank. Due to the high layout of the carbon tank, the layout structure is far from the front and rear of the vehicle, and the edge of the vehicle is far away , can effectively prevent the carbon canister from being hit by splashes. The arrangement structure adopts plug-in installation, and the assembly process is simple; the arrangement of the carbon tank and the engine compartment, and the airtightness inspection process of the fuel system are simple. The air vent of the carbon tank is capped to prevent the air vent of the carbon tank from being blocked by dust and debris.

Description

technical field [0001] The invention relates to an automobile chassis system, in particular to a design and assembly structure of an automobile carbon canister. Background technique [0002] In order to meet the evaporative emission requirements of fuel, existing cars are generally designed with carbon canisters, which are assembled on the entire vehicle and connected to the fuel tank and the engine through pipelines. In order to minimize the fuel vapor pipeline, the carbon canister is generally arranged near the fuel tank or the engine. In order to prevent liquid fuel from entering the carbon tank, the carbon tank is generally arranged higher than the fuel tank. [0003] For cars with a central engine and a vertical fuel tank, the carbon canister is generally arranged on the floor or the longitudinal beam between the fuel tank and the engine at present, but the floor height is too low during the development of new models, and the carbon canister cannot be arranged; and To...

AI Technical Summary

Problems solved by technology

Since the engine of the existing model is placed in the middle, the fuel tank is placed vertically, and the distance from the rear suspension and the spare tire is far away, the layout scheme provided by the above patents is not suitable.
