Abstract
The invention discloses a gas distribution device for an intake system of an internal-combustion engine. The gas distribution device comprises a distribution cavity and an intake interface connected to one end of the distribution cavity, and is characterized in that: the distribution cavity is connected with a plurality of gas outlet interfaces; each gas outlet connection pipe is connected with an intake manifold gas passage interface through a gas conveying pipe respectively; and the number of the gas outlet interfaces is equal to that of the intake manifold gas passage interfaces. Through the gas distribution device, the idea of directly distributing gas to be distributed to each gas passage of an intake manifold is realized by additionally arranging a device, the influence of air flow in a resonant cavity of the intake manifold on gas distribution is eliminated and uniform gas distribution is realized.
Description
Technical field
The present invention relates to internal combustion engine component, be specifically related to a kind of gas distributing device of induction system of internal combustion engine.
Background technique
Induction system of internal combustion engine usually needs in test portion gas is assigned to each air flue of intake manifold equably, realizes accurately test.Common way is the resonant cavity that the gas that needs distribute is directly charged into intake manifold at present, by air the natural inflow characteristic of gas to be allocated according to intake manifold is assigned in each air flue through resonant cavity, but the problem that exists is: because intake manifold intra resonant cavity air-flow complexity, there are numerous air-flow whirlpools in the part, can make air by resonant cavity in the process of intake manifold air flue motion, because of the phenomenon of each air flue air inlet inequality appears in the resistance of air-flow vortex arising, and then cause the situation of gas maldistribution to be allocated to occur.And when the air inlet amount changed, changing also can appear in the gas flow characteristic of intra resonant cavity, and change appears in the distribution of air-flow whirlpool simultaneously, can't effectively improve the uniformity that gas distributes by the design of eliminating the air-flow whirlpool.Therefore, how to eliminate the interior air flows of intake manifold resonant cavity, realize that uniform gas distributes, and with the accuracy of proof test, then becomes the new problem that people face the influence that gas distributes.
Summary of the invention
The gas distributing device that the purpose of this invention is to provide a kind of induction system of internal combustion engine, it can directly be assigned to gas to be allocated in each air flue of intake manifold equably, eliminate the interior air flows of intake manifold resonant cavity to the influence that gas distributes, guarantee that induction system of internal combustion engine carries out the accuracy of air inlet test.
The gas distributing device of a kind of induction system of internal combustion engine of the present invention, comprise a distribution chamber, be connected the intake interface of distribution chamber one end, it is characterized in that: distribution chamber is connected with a plurality of interfaces of giving vent to anger, each outgoing gas connection tube is connected with an intake manifold air flue interface by a gas dispatch tube respectively, and the quantity of the interface of giving vent to anger equates with intake manifold air flue quantity.
The gas distributing device of described a kind of induction system of internal combustion engine, its described distribution chamber and intake interface and each intake interface are an integral body.
The gas distributing device of described a kind of induction system of internal combustion engine, its described distribution chamber and first interface, second interface, the 3rd interface and the 4th interface of giving vent to anger of giving vent to anger of giving vent to anger of giving vent to anger is connected; First interface of giving vent to anger is connected with the first intake manifold air flue interface by the first gas dispatch tube; Second interface of giving vent to anger is connected with the second intake manifold air flue interface by the second gas dispatch tube; The 3rd interface of giving vent to anger is connected with the 3rd intake manifold air flue interface by the 3rd gas dispatch tube; The 4th interface of giving vent to anger is connected with the 4th intake manifold air flue interface by the 4th gas dispatch tube.
The gas distributing device of described a kind of induction system of internal combustion engine, its described first gas dispatch tube, the second gas dispatch tube, the 3rd gas dispatch tube and the 4th gas dispatch tube are rubber pipe.
Working principle is: gas to be allocated enters the distribution chamber from intake interface, after the gaseous diffusion, be communicated with each intake manifold air flue interface through respectively give vent to anger interface and gas dispatch tube, gas be assigned in each intake manifold air flue equably, thereby finish the gas assigning process.Internal-combustion engine is when aspirating stroke, because IO Intake Valve Opens and descent of piston can form forward pressure reduction between air inlet tube and each intake manifold air flue interface, makes gas to be allocated utilize this pressure reduction to enter the intake manifold air flue.
Beneficial effect of the present invention: the present invention has realized gas to be allocated directly is assigned to the conception of each air flue of intake manifold in the mode of add-on device, has eliminated that air flows has realized that to the influence that gas distributes uniform gas distributes in the intake manifold resonant cavity.
