Description
Technical field
The present invention relates to gas automotive fuel distributor field, more particularly to a kind of air induction device for automobile.
Background technology
The fuel that natural gas is used for vehicle motor can not only greatly reduce Vehicular exhaust pollution, while above natural gas
With being also to alleviate existing vehicle population rapid growth, environmental aggravation and the short present situation of petroleum resources effectively to arrange
Apply.Oil to gas is just worldwide popularized and promoted, and in China, also there is many buses, taxi even private car
Using natural gas as fuel.
In fuel gas vehicle, electronic controlled gas injection system is essential part, and the quality of its service behaviour is directly influenced
In the utilization rate of combustion gas and the output work of engine, existing cylinder gas burning system, natural gas, which entered after decompression, to be entered into spray rail,
The output end connection cylinder of rail is sprayed, cylinder intermittence is supplied.In the prior art, the spray rail for multi-cylinder typically sets a combustion
Gas inlet end, sets the quantity output end equal with number of cylinders, but combustion gas in pipeline when flowing, due to the internal pressure of leading portion
More than rear end, this allows for being more than the output end output pressure away from inlet end close to the output end output pressure of inlet end, made
Power distribution into each cylinder is uneven, and the uniformity of vehicle power output is influenceed in a short time, is run for a long time with such a operating mode
The uneven wear of cylinder will be developed into；The form of existing cylinder is more and more simultaneously, and such as new is provided with the complete of balancing frame
Aluminium three-cylinder engine, higher requirement is proposed to the flexibility that spray rail is installed.
The content of the invention
When being flowed for above-mentioned existing combustion gas in pipeline, because the internal pressure of leading portion is more than rear end, this allows for close
The output end output pressure of inlet end is more than the output end output pressure away from inlet end, causes the power of each cylinder to distribute not
Uniformly, the uniformity that influence vehicle power is exported in a short time, the uneven mill of cylinder will be developed into for a long time by being run with such a operating mode
Damage, and existing cylinder form it is more and more the problem of, the invention provides a kind of air induction device for automobile.
To solve the above problems, a kind of air induction device for automobile that the present invention is provided solves to ask by following technical essential
Topic：A kind of air induction device for automobile, including distribution cavity, the distribution cavity are the seal cavity surrounded by box body and cover plate, described point
With being connected with air inlet and multiple gas outlets, in addition to the quantity control unit equal with gas outlet quantity, the distribution cavity on chamber
Shape be centrosymmetric, be symmetrical set between the gas outlet relative to air inlet；
A connection flexible pipe is respectively connected with the gas outlet, the other end of the connection flexible pipe is respectively connected with isolating valve,
Fluid flow passageway is provided with body, the cut-off valve body, connection flexible pipe is connected on the arrival end of fluid flow passageway, described
Control unit corresponds the circulation status for controlling each bar fluid flow passageway with cut-off valve body.
Specifically, the air inlet set is used for the output end for connecting gas source, i.e. pressure-reducing valve, the gas outlet of setting is used for
Connection cylinder, i.e. source of the gas is entered in distribution cavity after the air inlet entrance present invention, and each outlet is uniformly entered by distribution cavity
Mouthful, then into cut-off valve body, being controlled to separate the fluid flow passageway circulation status of valve body by control unit, to realize to vapour
The periodic breaks supply of cylinder.In the present invention, be centrosymmetric using the shape of distribution cavity, between gas outlet relative to air inlet
Symmetrical set-up mode, is easy to implement flow resistance that air-flow flow to each gas outlet by air inlet quite, is easy to implement each
The uniform power output for waiting uninterrupted exhaust, being so easy to implement each cylinder of gas outlet.
In this structure, the structure type that the control unit of setting is separated with box body or cover plate, it is intended to be easy to use smaller box
Body and cover plate combination body, by taking existing household small-size vehicle as an example, the box body of such a structure type can be even more small using DN40
The structure of pipe one end welding end socket is made, or using monoblock cast into the less structure of diameter, and existing control unit is more
Using magnetic valve, above separate form not only eliminates single electromagnetism valve events to other magnetic valves or box body or lid upper connecting tube
Influence, can directly will cut-off valve body installation while for existing because the engine that the obtained cylinder structure of technological innovation differs
