A Gasoline Vapor Purification Device Using Magnetic Induction Drive

Abstract

The invention relates to a gasoline steam purifying device applying magnetic induction transmission. The device comprises a volute, a magnetic impeller and a shell; a stator and a motor are mounted in the shell in sequence from top to bottom; a rotating shaft of the motor is connected with the stator; the upper end of the shell is sealed through a separation plate; the volute is mounted at the upper end of the separation plate; a cavity is formed in the lower end of the volute; a magnetic impeller coaxial with the stator is rotationally mounted in the cavity; the cavity is vertically provided with an intake port opposite to the upper position of the center of the magnetic impeller; and an exhaust port is formed in the side wall of the cavity in the tangential direction of the magnetic impeller. The device controls the motor to rotate to drive the magnetic impeller to rotate so as to form a difference pressure; and oil steam is filled in an intake manifold to prevent from exhausting into air to realize the requirement of emission reduction.

Description

technical field [0001] The invention relates to the technical field of purification devices, in particular to a gasoline vapor purification device using magnetic induction drive. Background technique [0002] As there are more and more cars with turbochargers on the market, the negative pressure of the turbocharged intake manifold is lower than that of the naturally aspirated intake manifold, and the oil vapor collected by the carbon canister cannot be directly sucked into the intake manifold, so that the carbon After the tank collects oil vapor, it cannot be discharged, and the oil vapor cannot be fully utilized, resulting in waste of resources. If the carbon tank is full of oil vapor and cannot be discharged, it will be dangerous. In addition, my country will implement the National VI emission standard for engines in 2019, requiring gasoline Less volatile emissions. In order to solve the above problems, a device that sucks oil vapor from the carbon canister to the intake ma...
