Description
Technical field
The present invention relates to a kind of car engine machine technology, especially a kind of high-position air inlet pipe with secondary draining.
Background technique
At present, engine air inlet tube is motor desired gas passage, and air is removed airborne water droplet by suction tude, avoids motor because of the air water droplet detonation to occur too much, thereby motor is played a protective role.Especially travelling in heavy rain or stopping water inlet very easily occurs too much in the flame-out situation, and motor is damaged.The suction tude drainage pattern that at present domestic and international auto vendor generally adopts mainly is that design eddy flow impeller unit or electronics butterfly valve etc. add mechanism and reach drainage effect by the increase filter screen.Although these methods can effectively reduce the water inlet of motor, complex production process, cost is higher, the resource cost amount is larger.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of high-position air inlet pipe with secondary draining is provided, and this suction tude need not any peripheral hardware mechanism can realize the drainage effect identical with adding peripheral hardware mechanism, has simplified production procedure, reduce cost of production, saved resource.
For achieving the above object, the present invention adopts following technical proposals:
A kind of high-position air inlet pipe with secondary draining, the suction tude middle part offers suction port on the side, the suction port place is provided with grid, the suction port bottom has the first row mouth of a river that communicates with the external world, vertically be provided with the first aqueous vapor separating plate in the suction tude relative with suction port, the side of the first aqueous vapor separating plate closely links to each other with the suction tude inwall respectively with the base, and upper side and suction tude inwall have the space; The first aqueous vapor separating plate bottom, and the suction tude inwall relative with its position is provided with the second aqueous vapor separating plate that oblique lower camber extends; The top of the second aqueous vapor separating plate closely links to each other with the suction tude inwall respectively with side, and is gapped between bottom and the corresponding suction tude inwall; The second aqueous vapor separating plate bottom margin below is provided with the second row mouth of a river that communicates with the external world, other the 3rd aqueous vapor separating plate that extends obliquely that is provided with in the second row mouth of a river, the bottom of the 3rd aqueous vapor separating plate links to each other with edge, the second row mouth of a river, and side closely links to each other with the suction tude inwall; The suction tude bottom is connected with air filter; Described first, second, third aqueous vapor separating plate becomes S shape gas-entered passageway with the suction tude interior separation.
Described grid is by the intake grill place of rivet in suction tude.
The bottom of described the first aqueous vapor separating plate is curved, the top of the first aqueous vapor separating plate is to the suction tude inwall bending corresponding with it, and the transverse cutting area that forms between this place's first aqueous vapor separating plate and the suction tude inwall is more than or equal to 20% of air filter cross-section of pipeline area.
Form a low wide and up narrow intake grill passage between described the first aqueous vapor separating plate and the suction tude inwall.
Described the 3rd aqueous vapor separating plate is curved, and the part of the longitudinal projection of second, third aqueous vapor separating plate coincides.
In order not allow the water droplet that enters suction tude directly enter air filter, intake grill of the present invention is opened in the side, middle part of whole suction tude, and the outside is added with grid, with the intake grill place of rivet in suction tude.The intake grill bottom has the first row mouth of a river, and the intake grill passage is low wide and up narrow, forms the water droplet windage, can effectively stop water droplet to enter the opposite side tube chamber, and the water droplet more than 95% is hindered at the first row mouth of a river.Air flue is upwards by changing another downward tube chamber over to behind 1 180 ° the turning, this tube chamber bottom is offered the second row mouth of a river and is reached obliquely air flue, gas moves upward along air flue obliquely in tube chamber, be inhaled on a small quantity the water droplet of tube chamber, then fall under gravity into the second row mouth of a river, again turning back after gas makes progress enters air filter by connection mouth downwards.By twice filtration, just unnecessary water droplet is kept off fully in the outside like this, guaranteed the safety of motor.
In order to increase the effect of for the first time draining, the reduced cross-sectional area of the peak that the mixing wastewater with air fluid is climbed, but be not less than the air filter pipeline section long-pending 20%, under the prerequisite that guarantees system wind resistance, widen the ratio of suction port sectional area and this place's sectional area, cause the air pressure difference at two sections place to strengthen, than a lot of slowly at the peak place, the resistance of air at suction port place will be less than the peak place at the suction port place for air velocity, the suffered suction of suction port water droplet is less, falls easily.
The suction port sectional area should be done greatly as far as possible, but be subjected to the restriction of body dimensions, opening can't be accomplished infinity, so still having a small amount of raindrop can be inhaled into, therefore need to further stop the more raindrop of minor diameter with the 3rd aqueous vapor separating plate, so before the fluid of mixing wastewater with air enters into air filter, be provided with for the second time air-water separation passage in the suction tude bottom, allow the larger water droplet of inertia collide on the air intake pipe inwall, flow into the second row mouth of a river, be discharged to the outside, gas then enters another tube chamber along passage obliquely.
In addition, air intake filter screen (being grid) is designed in the side, and in order to reduce windage, the opening of filter screen is also done greatly as far as possible, reduce air to the shearing force of raindrop.
By above twice drainage procedure, the water droplet in the gas substantially all keeps off in the air filter outside.The present invention did simulation at truck.In the motor experiment of drenching with rain under the state of operation continuously, according to 6m
3The super extra torrential rain amount of/3min, the inflow of air filter only has 2ml, has reached usage requirement fully.
The present invention take Air Flow as foundation, structurally is optimized design to suction tude on the basis of mechanics principle, need not any peripheral hardware mechanism and can realize the drainage effect identical with adding peripheral hardware mechanism thereby reach.The present invention has simplified production procedure, has reduced cost of production, has saved social resources, thereby can form good social benefit.
