Activated carbon tank quick aging detection device and detection method thereof

Abstract

The invention discloses an activated carbon tank quick aging detection device, which comprises a vapor generating unit for generating gasoline vapor; an activated carbon tank, wherein an input end of the activated carbon tank is connected with an output end of the vapor generating unit, one end of the activated carbon tank is provided with an adsorption port and the other end thereof is provided with an exhaust port and a collection device, and the input end thereof is fixedly connected with the exhaust port of the activated carbon tank. The detection method of the detection device comprises the steps of: 1, heating the water in a water storage tank, filling air in an oil tank by an air pump; 2, filling the gasoline vapor of the oil tank in the activated carbon tank; 3, weighing the mass of the activated carbon tank adsorbing the gasoline vapor; 4, blowing air to the activated carbon tank by the air pump; 5, weighing the mass of the activated carbon tank desorbing the gasoline vapor; and 6, repeating the steps 2 to 5 many times until the increased weight of the activated carbon tank becomes steady. The device and the method can control the volume and temperature of the gasoline vapor so that the detection process is closer to actual using condition, and can rapidly detect the steady mass of the activated carbon tank to determine the adsorption and desorption abilities of the activated carbon tank.

Description

technical field [0001] The invention relates to a detection device for an activated carbon tank, in particular to a detection device for rapid aging of an activated carbon tank and a detection method thereof. Background technique [0002] Activated carbon tank refers to a tank filled with activated carbon, which is used to absorb the gasoline vapor escaped from the fuel tank and carburetor when the engine is turned off, and blow out the adsorbed gasoline to burn when the engine is started. The activated carbon canister is a critical component in the ignition system and exhaust system. When the engine is ignited, the gas inhaled into the activated carbon tank is introduced into the engine intake pipe through the carbon tank control valve. The control valve body is determined by the control unit of the EFI system to determine its opening and closing and absorption degree. Activated carbon canisters can greatly reduce air pollution caused by exhaust emissions. [0003] Motorc...

AI Technical Summary

Problems solved by technology

Therefore, the performance of activated carbon canister adsorption and desorption plays a vital role in the emission of exhaust gas, but the detection method for the rapid aging equipment of activated carbon canister adsorption and desorption is not perfect, resulting in the activated carbon of the prior art The stability of the tank is not good
