Abstract
The present invention provides an air dust remover without a filtering core of an internal-combustion engine, which is a dry-type, straight-line and reverse suction type air dust remover. The air dust remover adopts the principle that a strong air flow generated when air flows discharges particular fly ash in the air flow by blocking and separating the air flow under the action of centrifugal force. Simultaneously, transverse dust exhausting wind force is added on the lateral face of a rotary air flow by a speed adjustable dust exhausting fan to lead micro fly ash which rotates in the middle of the air flow to be blown. The air dust remover can be directly matched with an internal combustion engine, and can also be matched with an air filter of the original vehicle to further improve air inlet quality. Compared with the prior art, the air dust remover has the advantages of economy, application and good dust removing effect, is suitable for internal combustion engines which are configured on any mechanical device, is also suitable for any region and any working environment, ensures the air inlet quality of the internal combustion engines, extends the service life of the internal combustion engines, improves the service performance of the internal combustion engines, and reduces the use cost of the internal combustion engines.
