Abstract
A vehicle engine intake system with a fan-ejected dust removal device comprises an intake pipe. The gas outlet end of the intake pipe is fixedly connected with a bellows. The outlet end of the bellows is connected with the gas inlet end of an air filter through a transition bend. A pre-filter is disposed at a gas inlet of the intake pipe. The bottom of the pre-filter is provided with an ash outlet which is hermetically connected with an inlet of a one-way flow divider. A first outlet of the one-way flow divider is hermetically connected with a joint, and the other end of the joint is hermetically connected with a gas inlet of a direct-current fan. A gas outlet of the direct-current fan is a dust removal hole. A one-way valve core is disposed in the one-way flow divider. Opening direction of the one-way valve core is the same as intake direction of the direct-current fan. The one-way valve core is used for controlling opening and closing of a connecting pipeline for the one-way flow divider and the direct-current fan. The vehicle engine intake system allows for automatic dust removal of the pre-filter so that filtering effect of the pre-filter is improved and the service life of the air filter is prolonged, and is simple in structure and easy to arrange.
