Exhaust gas recycling device, control method and turbocharging system

Abstract

The invention provides an air leakage recycling and reusing device, a control method and a turbocharging system, and belongs to the technical field of air leakage reusing. The air leakage recycling and reusing device comprises an air storage unit and a control unit, and a pressure sensor is arranged on the air storage unit; the gas storage unit is connected with a first pipeline and a second pipeline, the gas storage unit is communicated with the gas leakage pipe through the first pipeline, and the gas storage unit is communicated with the intercooler gas outlet pipe through the second pipeline; the control unit comprises a first control valve and a second control valve, the first control valve is electrically connected with the pressure sensor and controls the air leakage pipe to communicate with the first pipeline or the air filter air outlet pipe according to the pressure value of the pressure sensor; the second control valve is arranged on the second pipeline and controls opening and closing of the second pipeline according to the working state of the engine. According to the leaked gas recycling device provided by the invention, when the engine receives oil, pressure gas can be prevented from being directly discharged into the air outlet pipe of the air filter, and when the engine is refueled, the pressure gas in the original leaked gas is reasonably utilized.

Description

technical field [0001] The invention belongs to the technical field of exhaust gas recycling, and more particularly, relates to a leakage gas recovery and reuse device, a control method and a turbocharging system. Background technique [0002] With the continuous development of the automobile industry and the continuous improvement of people's living standards, automobiles have spread all over the streets and alleys. The air intake system on the automobile is equivalent to the human respiratory system, providing sufficient clean gas for the engine and increasing the power of the vehicle. Existing vehicles are matched with turbocharged engines, and the pressure is increased by compressing the gas through the supercharger, so as to give the engine more clean gas full of oxygen content, so as to improve the power performance. [0003] However, the engine does not need a lot of gas when the oil is collected. At this time, the supercharger is still working, and the pressure in th...
