Description
Technical Field
The invention belongs to the field of vehicle control, and particularly relates to a control method, a control device, control equipment and a vehicle for a carbon tank electromagnetic valve.
Background
The activated carbon tank is a device which is installed on an automobile and used for reducing air pollution caused by fuel evaporative emission and simultaneously increasing the fuel efficiency of the automobile, and the working principle of the activated carbon tank is as follows: when the engine is shut down, the fuel consumption can cause negative pressure inside the fuel tank due to the tightness of the fuel tank, and gasoline can volatilize oil vapor more easily than under normal pressure under the action of the negative pressure, and finally the gasoline can reach the balance with the atmospheric pressure. Then, along with the diffusion movement of oil gas molecules in the oil tank, a part of the oil gas molecules can diffuse to the activated carbon tank along with an oil vapor pipeline of the oil tank, and the granular activated carbon which is prepared by a special process and is particularly suitable for adsorbing the oil gas molecules can firmly lock the oil gas molecules in the activated carbon tank so as to prevent the oil gas molecules from diffusing to the atmosphere to cause air pollution. When the engine is started, the carbon canister battery valve is opened, so that the exhaust port of the activated carbon canister is opened, and the oil vapor which is locked in the activated carbon canister is sucked into the intake manifold of the engine as fuel along with the suction action of the engine. At this point, the cycle of activated carbon canister operation is completed until the engine is again shut down and the cycle is resumed.
In recent years, the work of our country on environmental protection is more and more important, the standard for the emission of automobile pollutants is more and more strict, and the newly-implemented 'national six' automobile emission standard greatly strengthens the limit value of the automobile pollutants. Under the background, in order to meet the requirement of the limit of the pollutants in the automobile, automobile manufacturers choose to increase the volume of the activated carbon tank. However, as the volume of the activated carbon tank increases, the flow rate of the carbon tank electromagnetic valve also increases correspondingly, so that the seating force of the needle valve of the carbon tank electromagnetic valve is increased when the activated carbon tank is desorbed. When the engine of vehicle is in the idle speed operating mode, can obviously feel in the car because the needle valve of carbon tank solenoid valve sits the noise that produces, and then influence whole car NVH performance.
