Abstract

The invention discloses an air filter for an oil-saving vehicle, relating to the technical field of air filters in locomotives. The air filter mainly comprises a main filtering core, an auxiliary filtering core, a top cover and a bottom cover, wherein main parts of the main filtering core and the auxiliary filtering core comprise outer nets, filtering paper and inner nets; the diameters of filtering holes of the filtering paper in the main filtering core and the auxiliary filtering core are 55-60 micrometers; the bottom cover is of an integrated structure and is made of elastic combined polyether materials; the surface of the bottom cover is provided with a ring-shaped convex strip; the top cover is also made of elastic combined polyether materials. The air filter disclosed by the invention has the advantages that the air filtering flow is large, the burning efficiency of gasoline is guaranteed, the oil-saving effect is obvious and the whole sealability is good.

Description

The fuel-economizing air filter for vehicle

Technical field

The present invention relates to the locomotive air filter technical field, be specifically related to a kind of fuel-economizing air filter for vehicle.

Background technique

Air-strainer is arranged in engine aspirating system, the assembly that it is comprised of the filter component of one or several clean air.Its Main Function is that filtering will enter objectionable impurities in the air of cylinder, to reduce the premature wear of cylinder, piston, piston ring, valve and valve seat.

Existing air-strainer is by main filter core, auxiliary filter core, top cover and bottom form, the critical piece of main filter core and auxiliary filter core comprises outer net, filter paper and Intranet, the air filter flow of well-known vehicle filter core should be greater than the specified air inflow of adapted motor, but the filter opening aperture on the filter paper surface that filter core is used is 50 microns left and right, aperture is less, although the airborne objectionable impurities of filtering effectively, but the air filter flow is subject to certain restrictions, especially after filter cleaner uses a period of time, actual air filter flow can be lower than the design air filter flow of air-strainer, so just there will be the specified air inflow of the air filter flow of filter core lower than the adapted motor, affect the fuel efficiency of automobile, cause the gasoline partial combustion, and current outer net and Intranet all adopt plastic material to make, moulding skeleton rigidity is poor, grown service time, there will be bending, affect the air filter efficiency of filter core.The bottom of current air-strainer as shown in Figure 1, mostly is split-type structural in addition, is comprised of annular bottom 8 and inner cap 9, and inner cap 9 is made for hard material, and the split-type structural sealing is not good, leakage phenomenon easily occurs after long-term the use.

Summary of the invention

The purpose of this invention is to provide a kind of fuel-economizing air filter for vehicle, the air filter flow existed with the solution prior art hangs down and the poor problem of sealing.

The present invention mainly is comprised of main filter core, auxiliary filter core, top cover and bottom, the critical piece of main filter core and auxiliary filter core comprises outer net, filter paper and Intranet, the filter opening aperture that solves technological scheme that its technical problem adopts and be filter paper in main filter core and auxiliary filter core is 55～60 microns, bottom is the integral type structure, by having flexible combined polyether material, make, the bottom outer surface arranges a ring rib, and top cover is also made by having flexible combined polyether material.

The outer net of above-mentioned main filter core and auxiliary filter core and Intranet are zinc-plated net.

The invention has the beneficial effects as follows:

1, the air filter flow is large.By long-term experiment, put into practice, by the filter opening borehole enlargement to 55 of filter paper～60 microns, when not affecting the air-filtering effect, improved the air filter flow of filter core, guaranteed the perfect combustion of gasoline, bottom employing simultaneously has flexible combined polyether material and makes, along with air suction air-strainer, bottom is shrinkage expansion thereupon, play the effect of similar bellows, improved air inlet efficiency, thereby improved the fuel efficiency of automobile, have very significantly oil-saving effect, but about 1.1～1.3 liters of oil of per 100 km fuel-economizing.

2, good airproof performance.Bottom adopts integral structure, and top cover and bottom all adopt flexible material to make simultaneously, can with the better combination of frame of filter element, improved overall tightness, outer net and Intranet are zinc-plated net simultaneously, have improved the rigidity of frame of filter element.

The accompanying drawing explanation

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the bottom of prior art air-strainer;

Fig. 2 is structural representation of the present invention;

Fig. 3 is schematic top plan view of the present invention;

Fig. 4 is bottom cover structure schematic diagram of the present invention.

1 main filter core, 2 auxiliary filter cores, 3 outer nets, 4 Intranets, 5 top covers, 6 bottoms, 7 filter paper, 8 annular bottoms, 9 inner caps, 10 ring ribs in figure.

Embodiment

As Fig. 2, Fig. 3 and shown in Figure 4, a kind of fuel-economizing air filter for vehicle, mainly by main filter core 1, auxiliary filter core 2, top cover 5 and bottom 6 form, the critical piece of main filter core 1 and auxiliary filter core 2 comprises outer net 3, filter paper 7 and Intranet 4, in main filter core 1 and auxiliary filter core 2, the filter opening aperture of filter paper 7 is 55～60 microns, bottom 6 is the integral type structure, by having flexible combined polyether material, make, bottom 6 outer surfaces arrange a ring rib 10, top cover 5 is also made by having flexible combined polyether material, the outer net 3 of main filter core 1 and auxiliary filter core 2 and Intranet 4 are zinc-plated net.

Claims

1. fuel-economizing air filter for vehicle, mainly by main filter core, auxiliary filter core, top cover and bottom, formed, the critical piece of main filter core and auxiliary filter core comprises outer net, filter paper and Intranet, the filter opening aperture that it is characterized in that filter paper in main filter core and auxiliary filter core is 55～60 microns, bottom is the integral type structure, by having flexible combined polyether material, make, the bottom outer surface arranges a ring rib, and top cover is also made by having flexible combined polyether material.

2. fuel-economizing air filter for vehicle according to claim 1, is characterized in that the outer net of main filter core and auxiliary filter core and Intranet are zinc-plated net.
