According to the above technical scheme, the utility model discloses a level filtering of impurity such as rainwater, ice and snow has been realized to the intake pipe shroud, has realized through the air inlet net that great inclusion particle's second grade filters, and the pipeline structure who appears through " V " has realized the tertiary centrifugal filtration to fine particle and dust, simultaneously, realized the quick discharge of debris through the drain that leaks hopper -shaped, dripped the cover through duckbill rubber and prevent the ground debris to get into air intake system. The utility model discloses filter all kinds of debris in the air effectively, improved the purifying effect of admission line to guarantee the quality of admitting air of engine, improved the combustion efficiency of engine, reduced the wearing and tearing of piston and cylinder liner, improved life.
Description
Technical field
This utility model is related to passenger car field, and in particular to a kind of rearmounted car inlet air filter system.
Background technology
At present, car especially bus, mostly adopt rear engine, and rear top is adopted rearmounted engine charge more
Intake method.With the development and the raising of levels of emissions of engine technology, state five and above discharge electromotor are to the pure of air
Cleanliness requires higher.Therefore, with respect to gusset air inlet more be dried, cleaning top intake method, the development in later stage occupy compared with
Many advantages.However, it is many by the way of the ventilation of top straight tube in industry at present, to fine dust and rainwater in air inlet, it is impossible to
Effectively filter, remove.
Utility model content
The purpose of this utility model is to provide a kind of rearmounted car inlet air filter system, this system improves admission line
Filter effect, so as to ensure that the air mass of electromotor, improve the efficiency of combustion of electromotor, reduce piston and cylinder sleeve
Abrasion, improve service life.
For achieving the above object, this utility model employs technical scheme below：Including air inlet pipe, the air inlet pipe it is upper
Side is provided with air inlet shroud lid, and described air inlet shroud lid is fixed on car load vehicle body and leaves gap with bodywork surface, it is described enter
The top of trachea is connected with air inlet grid, and the bottom of air inlet pipe is connected with blow-off pipe.
The bottom of the air inlet pipe forms funnelform sewage draining exit, and described sewage draining exit is connected with blow-off pipe.
The bottom of the blow-off pipe and rubber cover that drips is connected.
Described air inlet pipe is with V-arrangement or U-shaped structure and can produce the pipeline of centrifugal action.
Described air inlet pipe is fixed on car load vehicle body, and the top of air inlet pipe is higher by Top Skin at least 20mm.
Described rubber drips cover and drips cover for Duckbill type rubber.
As shown from the above technical solution, this utility model realizes the one of the impurity such as rainwater, ice and snow by air inlet shroud lid
Level is filtered, and by air inlet grid the cascade filtration of larger particles debris is realized, and it is right to be realized by the pipeline configuration of " V " shape
The three-level centrifugal filtration of fine particle and dust；Meanwhile, the quick discharge of debris is realized by funnelform sewage draining exit, pass through
Duckbill type rubber drip cover prevent ground debris enter gas handling system.This utility model has effectively filtered all kinds of miscellaneous in air
Thing, improves the clean-up effect of admission line, so as to ensure that the air mass of electromotor, improves the burning effect of electromotor
Rate, reduces the abrasion of piston and cylinder sleeve, improves service life.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This utility model is described further below in conjunction with the accompanying drawings：
A kind of rearmounted car inlet air filter system as shown in Figure 1, including air inlet pipe 3, the top of air inlet pipe 3 is provided with air inlet
Shroud lid 1, air inlet shroud lid 1 is fixed on car load vehicle body and leaves gap with bodywork surface, and the gap is used to ensure air inflow；
The top of air inlet pipe 3 is connected with air inlet grid 2, and the barrel hole size on grid 2 can as needed carry out selection adjustment；Air inlet pipe
3 bottom is connected with blow-off pipe 4.
Further, the bottom of air inlet pipe 3 forms funnelform sewage draining exit 31, and sewage draining exit 31 is connected with blow-off pipe 4.
Further, the bottom of the blow-off pipe 4 and rubber cover 5 that drips is connected.Further, rubber drips cover 5 for duckbilled
Type rubber drips cover.In vehicle traveling, the rubber of the Duckbill type cover that drips can be effectively isolated water smoke, sandstone that ground flies up etc., protect
The drying of card air inlet and cleaning.
Further, air inlet pipe 3 is with V-arrangement or U-shaped structure and can produce the pipeline of centrifugal action.Specifically, i.e.,
Bypass has pipeline in air inlet pipe 3, and pipeline and the air inlet pipe of bypass form the structure of V-arrangement or U-shaped, to produce operating on centrifugal force.
This utility model is preferably v-shaped structure, easily manufactured, low cost.
Further, air inlet pipe 3 is fixed on car load vehicle body, and the top of air inlet pipe 3 is higher by Top Skin at least 20mm.
Operation principle of the present utility model and the course of work are as follows：
After engine start, vacuum is formed in the outlet of air inlet pipe 3, extraneous air and debris are inhaled into gas handling system, pass through
Air inlet shroud lid 1 filters the impurity such as rainwater, ice and snow, stone, filters larger by the closeer air inlet grid 2 of air inlet pipe top eyelet
The debris such as leaveves, the scraps of paper of granule, air is entered after air inlet pipe 3, and in the " V " shape corner of air inlet pipe, density ratio air is big
Tiny drops of water, dust granule etc. can be fallen in the sewage draining exit of the lower hopper shape of air inlet pipe 3, and by blowdown due to centrifugal action
Pipe 4 is discharged outside car；Meanwhile, centrifugal action can be such that micro-air goes out from sewage draining exit due to inertia, it is to avoid the backflow of dust；Vehicle
In traveling, the rubber of the Duckbill type cover that drips can be effectively isolated water smoke, sandstone that ground flies up etc., it is ensured that the drying of air inlet and clear
It is clean.
In sum, this utility model realizes the single filter of the impurity such as rainwater, ice and snow by air inlet shroud lid, passes through
Air inlet grid realizes the cascade filtration of larger particles debris, realized to fine particle by the pipeline configuration of " V " shape and
The three-level centrifugal filtration of dust；Meanwhile, the quick discharge of debris is realized by funnelform sewage draining exit, by Duckbill type rubber
The cover that drips prevents ground debris from entering gas handling system.This utility model has effectively filtered all kinds of debris in air, improves
The clean-up effect of admission line, so as to ensure that the air mass of electromotor, improves the efficiency of combustion of electromotor, reduces work
The abrasion of plug and cylinder sleeve, improves service life.
Embodiment described above is only that preferred implementation of the present utility model is described, not to this practicality
New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of this utility model claims determination
In the range of.
