Description
Technical Field
The invention relates to the technical field of carbon tanks, in particular to a carbon tank assembly, a supporting piece, a tank body and a method for improving injection molding indent of the tank body.
Background
The canister is typically mounted between the gasoline tank and the engine. Because gasoline is a volatile liquid, the fuel tank is often full of vapour at normal atmospheric temperature, and this can increase the inside pressure of fuel tank, will produce certain danger when pressure reachs a definite value, and people set up the carbon tank again in view of fuel economy and environmental protection, and the carbon tank is inside to be filled by the very strong active carbon of adsorptivity, and unnecessary fuel steam is no longer discharged to the atmosphere in the fuel tank, but introduces the active carbon tank. The role of the evaporative emission control system is to introduce vapors into the combustion and prevent evaporation into the atmosphere. An important part of this process is the canister storage.
Because the activated carbon has the adsorption function, when the automobile runs or is shut down, gasoline vapor in the fuel tank enters the upper part of the activated carbon tank through the pipeline, and fresh air enters the activated carbon tank from the lower part of the activated carbon tank. After the engine is shut down, gasoline vapor and fresh air are mixed in the tank and stored in the activated carbon tank, after the engine is started, an electromagnetic valve of the fuel evaporation and purification device arranged between the activated carbon tank and the intake manifold is opened, and the gasoline vapor in the activated carbon tank is sucked into the intake manifold to participate in combustion, so that the aims of saving fuel and protecting the environment are fulfilled.
However, the carbon tank body is easy to deform inwards during injection molding, so that the rejection rate is high, the production efficiency is low, normal production and use are affected, and generally, the investment on an injection mold and an injection molding process needs to be increased to improve the deformation condition, so that the research and development investment cost is high.
