Problems solved by technology

The amount of gas desorbed by the carbon canister per unit time, that is, the desorption efficiency, determines its working ability in the actual use of the vehicle. At present, due to design limitations, the amount of gas desorbed by the canister is small, and the desorption efficiency needs improvement

Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings to facilitate a clearer understanding of the present invention, but they do not constitute a limitation of the present invention.

[0011] As shown in FIG. 1 , an automobile engine carbon canister desorption device includes a fuel tank 1 and an intake pipe 2, a carbon canister 3 is connected between the fuel tank 1 and the intake pipe 2, and the intake pipe 2 is along the intake air. The direction is connected with an air filter 4, a supercharger 5, an intercooler 6, and a pressure-stabilizing chamber 7. The fuel air inlet 301 of the carbon canister 3 is connected to the fuel tank 1, and the atmosphere of the carbon canister 3 The through-hole 302 is communicated with the pressure-stabilizing chamber 7, the connecting pipeline between the atmospheric through-hole 302 of the carbon canister 3 and the pressure-stabilizing chamber 7 is provided with a first solenoid...

Abstract

The invention discloses an automobile engine charcoal canister desorption device. The automobile engine charcoal canister desorption device comprises a fuel tank and an air-in pipe, wherein a charcoal canister is connected between the fuel tank and the air-in pipe, an air filter, a supercharger, an intercooler and a pressure stabilizing cavity are sequentially connected to the air-in pipe in the air-in direction, a fuel air inlet of the charcoal canister is connected with the fuel tank, an air through hole of the charcoal canister is communicated with the pressure stabilizing cavity, and a desorption opening of the charcoal canister is communicated with the air-in pipe between the supercharger and the air filter. A pressure source and hot air on a super-charged engine are utilized to carry out charcoal canister desorption, a pressure difference in the desorption process is greatly improved, desorption air flow is increased under the condition of same desorption time, and the charcoal canister desorption efficiency is improved. The high air temperature in the pressure stabilizing cavity is favorable to the accomplishment of the fuel steam desorption process in charcoal powder, so that the charcoal canister desorption efficiency is further improved. As air in the pressure stabilizing cavity passes the filter, the service life of the charcoal powder is improved through the utilization of clean air in desorption. The work capability of the charcoal canister on the whole vehicle is improved.

Description

technical field [0001] The invention relates to an automobile steam emission control system, in particular to a carbon canister desorption device of an automobile engine. Background technique [0002] Since gasoline is a volatile liquid, the fuel tank of automobiles is often filled with steam at room temperature. The fuel evaporative emission control system is used to introduce fuel vapor into the engine for combustion to prevent fuel vapor from volatilizing into the atmosphere, causing fuel waste and environmental pollution. In the process, the carbon canister plays an important role. [0003] The carbon canister is generally installed between the fuel tank and the engine. After the engine is turned off, the fuel vapor and fresh air are mixed in the canister and are adsorbed and stored in the activated carbon canister. When the engine is started, it is installed in the activated carbon canister and the intake manifold. The electromagnetic valve between them is opened, the ...
