The invention discloses an automobile fuel evaporation pollution control device in the technical field of automobile fuel pollution. The device comprises a connecting pipe with an external thread, a first screw plug, a first air pressure sensor, a reaction barrel and a micro electromagnetic valve. The first screw plug is screwed at the top end of the connecting pipe. The device is connected with an existing automobile fuel tank threaded opening through the external thread on the connecting pipe, and an automobile power supply supplies power to the whole device. The first air pressure sensor and a second air pressure sensor detect air pressure inside and outside a fuel tank. Data comparison is carried out through a processor and a comparison unit. If the internal air pressure and the external air pressure are different, a micro motor and the micro electromagnetic valve are started, and reversely-installed fan blades suck air to enable the internal air pressure and the external air pressure to be the same. Evaporated gasoline is filtered through an activated carbon layer, and pollution is reduced. The device is not provided with a run-through air pressure balance channel, direct diffusion of the evaporated gasoline into the atmosphere is reduced, and the operation is convenient.
Description
technical field [0001] The invention relates to the technical field of automobile fuel pollution, in particular to an automobile fuel evaporation pollution control device. Background technique [0002] With the improvement of people's living standards, the number of gasoline vehicles has increased significantly. At the same time, the environmental pollution caused by exhaust gas from vehicles has become more and more serious, so that it has become the main source of pollution in cities, causing adverse effects on the natural climate and ecological environment of the earth. When the fuel tank is designed, a balance valve or a vent hole is designed on the fuel tank cap to ventilate. When the internal pressure is low, the outside air will be replenished. Because of high temperature or turbulence, when the internal pressure is high, the air will be discharged outside. Maintain the pressure inside the fuel tank within a certain range, so that the oil pump can discharge oil smoot...
