Description
Technical field
The present invention relates to gas automotive fuel distributor field, more particularly to a kind of feeder.
Background technology
The fuel that natural gas is used for vehicle motor not only can greatly reduce Vehicular exhaust pollution, above natural gas simultaneously
Be also alleviate existing vehicle population rapid growth, environmental aggravation and petroleum resources shortage present situation effectively arrange
Apply.Oil to gas is just worldwide being popularized and is being promoted, and in China, also has many buses, taxi even private car
With natural gas as fuel.
In fuel gas vehicle, electronic controlled gas injection system is requisite part, and the quality of its service behaviour directly influences
The utilization rate of combustion gas and the output work of electromotor, in existing cylinder gas burning system, natural gas entered in spray rail after entering decompression,
The outfan of spray rail connects cylinder, the intermittent supply to cylinder.In prior art, for spray rail one combustion of general setting of multi-cylinder
Gas inlet end, the setting quantity outfan equal with number of cylinders, but when combustion gas is flowed in pipeline, intrinsic pressure due to leading portion
More than rear end, the outfan output pressure that this allows for close inlet end is more than the outfan output pressure away from inlet end, makes
Become the power maldistribution of each cylinder, the uniformity of impact vehicle power output, is run with this kind of operating mode for a long time in a short time
The uneven wear of cylinder will be developed into.
Content of the invention
When flowing in pipeline for above-mentioned existing combustion gas, due to leading portion intrinsic pressure more than rear end, this allows for close
The outfan output pressure of inlet end is more than the outfan output pressure away from inlet end, causes the power of each cylinder to distribute not
Uniformly, the uniformity of impact vehicle power output in a short time, is run with this kind of operating mode for a long time and will develop into the uneven mill of cylinder
The problem damaged, the invention provides a kind of feeder.
For solving the above problems, a kind of feeder that the present invention provides is by following technical essential come solve problem: one
Plant feeder, including distribution cavity, described distribution cavity is the seal cavity being surrounded by box body and cover plate, described distribution cavity connects
There are air inlet and multiple gas outlet, also include the quantity control unit equal with gas outlet quantity, described control unit and gas outlet one
It is applied to for a pair control each gas outlet circulation status, the shape of described distribution cavity is centrosymmetric, phase between described gas outlet
