Abstract
The invention discloses an engine air intake prefiltering method and system. The system is used for improving the cleanliness of engine air intake and comprises a prefiltering tube, a rotational flow fan, an air outlet pipe and a support in the engine air intake direction. High-speed airflow entering the engine air intake pushes the rotational flow fan to rotate to generate rotating airflow, water, dust and impurities with the densities larger than the density of air are discharged along an interlayer between the inner wall of the prefiltering tube and the outer wall of the air outlet pipe under the centrifugal effect of the high-speed rotating airflow, and clean air enters the engine air intake system through the air outlet pipe.
Description
Technical field
The present invention relates to automotive engine air intake system technical field, be specifically related to a kind of engine charge pre-flock method and system.
Background technique
The effect of the gas handling system of automobile provides clean, dry, that temperature is suitable air to carry out burning to reduce engine scuffing to greatest extent and keeping best engine performance to motor.Therefore require that gas handling system has very high filtering efficiency, the dust in removing air and moisture.
Commercial car operating conditions is severe, traditional Design of Inlet is for preventing automobile in the course of the work, dust in air and moisture enter into gas handling system, engine inlets suction port becomes 90 degree or inverse relationship towards with the direction of travel of automobile, in order to dedusting, the object that dewaters in inlet structure originally, the pressure refluence effect of venetian blind (or whirl hole) and manger board causes intake resistance large, enter the impurity after gas handling system not easily to discharge, affect the working life of filter core, increase later stage manual maintenance cost high and also can affect the travelling comfort of occupant.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of engine charge pre-flock method and system, in order to improve the turbidity test of engine charge.
Technological scheme of the present invention:
A kind of pre-filtering method of engine charge, pre-filtering is carried out at engine intake place, along engine charge direction, one section of pre-chimney filter is being set, in pre-chimney filter, settle one has at least the eddy flow of 2 rotation blades to fan, after the eddy flow fan of rotation blade airflow direction, steam outlet pipe is being installed, described steam outlet pipe is coaxial with pre-chimney filter, and steam outlet pipe is positioned at one end of pre-chimney filter inside and pre-chimney filter forms interlayer; The high velocity air that entered by engine charge promotes eddy flow fan and rotates and produce swirling eddy, and density is greater than the impurity such as the moisture of air density and dust and discharges along described interlayer, and middle clean air enters engine aspirating system by steam outlet pipe.
A kind of engine charge pre-flock system, comprise pre-chimney filter, eddy flow fan, steam outlet pipe, support, described pre-chimney filter is a segment pipe, and axial position is therein equipped with eddy flow fan, and eddy flow fan has 2 rotation blades at least; After the eddy flow fan of rotation blade airflow direction, steam outlet pipe is being housed, steam outlet pipe is fixed on on the same axis of pre-chimney filter by support, one end of steam outlet pipe is positioned at the inside of pre-chimney filter, and the other end access engine aspirating system, described support is between pre-chimney filter and steam outlet pipe.
Beneficial effect of the present invention:
The present invention just increases a kind of pre-flock device in gas handling system front end, relative to traditional engine charge pipeline structure, have the following advantages: most moisture and dust can be made directly to discharge along the interlayer of pre-chimney filter under the effect of eddy flow fan, dedusting, water removal effect are good, convenient later maintenance, and air power noise can not be produced because wind direction sharply changes formation airflow breakaway.
