Abstract
The utility model discloses a gas engine gas track which is characterized in that a gas track channel is rectangular, gas outlets are arranged under the gas track channel corresponding to cylinders of a gas engine, and each gas outlet and a corresponding electric control gas nozzle are sealed through an O-shaped sealing ring. Each electric control gas nozzle is embedded in a gas inlet manifold of a corresponding cylinder, the gas track channel is provided with a support, and the support is fixedly connected with a gas engine gas inlet pipe through bolts. After gas is decompressed by a reducing valve, the gas does not enter cylinder nozzles directly to be burnt, the gas first enters the gas track channel which has a buffering effect on gas, so that the pressure of the gas entering the nozzles is completely identical, and the flow is even. The gas engine gas track is simple in structure and convenient to manufacture and install. Gas leakage cannot happen easily, and working evenness of the cylinders of the gas engine and the whole engine performance can be remarkably improved.
Description
Technical field
The utility model gas engine accessory, is specifically related to a kind of for the gas rail of stablizing fuel gas injection pressure is provided.
Background technique
In gas engine, after the decompression of natural gas via reduction valve, enter gas rail, the effect of gas rail is that combustion gas is carried out distributing to each cylinder blast nozzle after voltage stabilizing, makes each blast nozzle under identical pressure, carry out work.Therefore the quality of gas rail performance, will directly have influence on uniformity and the overall performance of the each cylinder working of gas engine.While carrying out at present the experiment of blast nozzle pressure uniformity, by gas burning system, producer carries, and this gas rail pressure stabilizing cavity is relatively narrow, installs and needs design in addition to rely on support, has increased complete machine experimental cost.Proposition of the present utility model, can make combustion gas enter cylinder very even.
Summary of the invention
The purpose of this utility model is that a kind of gas-type engine air track of stable jet pressure is provided.
Below in conjunction with accompanying drawing, know-why of the present utility model and structure are described.
Its technological scheme of gas-type engine air track is: gas rail passage is rectangular, and below gas rail passage, each cylinder of corresponding gas engine is equipped with an air outlet, adopts the sealing of O type circle between air outlet and electronic controlled gas injection mouth.Electronic controlled gas injection mouth is embedded in each cylinder intake manifold, and gas rail passage is provided with support, and support is connected and fixed by bolt and gas engine suction tude.
Principle of the present utility model is comparatively simple, combustion gas is not directly to enter nozzle cylinder to burn after reduction valve decompression, but be introduced into gas rail passage, gas rail passage plays the effect of a buffering to combustion gas, the gaseous-pressure that can ensure like this to enter nozzle is identical, and flow is also very even.
Feature of the present utility model and beneficial effect: simple in structure, convenient making and installation, and combustion gas is difficult for revealing.Owing to making adding of gas rail passage, gas inlet pressure is even, flow is consistent, can obviously improve uniformity and the overall performance of the each cylinder working of gas engine.
Brief description of the drawings
Fig. 1 is principle of the present utility model and structural representation.
Fig. 2 is three-dimensional structure diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, structure of the present utility model is further described.
Gas-type engine air track, comprising: gas rail passage, electronic controlled gas injection mouth, support, bolt and O RunddichtringO etc.Its structure is: gas rail passage 1 is rectangular, and below gas rail passage, each cylinder of corresponding gas engine is equipped with an air outlet 2, adopts O type circle 4 to seal between air outlet and electronic controlled gas injection mouth 3.Electronic controlled gas injection mouth is embedded in each cylinder intake manifold, and gas rail passage is provided with support 5, and support is connected and fixed by bolt 6 and gas engine suction tude 7.In order to prevent that connecting suction tude sebific duct comes off and seal combustion gas, the front end of gas rail passage suction port 8 is horn shape.Gas rail passage and suction port, air outlet are integrated foundry goods.
Gas rail channels designs is rectangular, matches with motor global design, has increased the space of pressure stabilizing cavity, reduces combustion gas disturbance in orbit.Combustion gas enters gas rail passage through reduction valve, pneumatic hose, and passage plays the effect of pressure stabilizing cavity, and the combustion gas after voltage stabilizing is distributed to each cylinder blast nozzle by gas rail passage air outlet.Blast nozzle is embedded in each cylinder intake manifold, and gas rail passage is connected and fixed by M10 bolt and gas engine suction tude.Under the effect of bolt impacting force, seal ring, blast nozzle and intake manifold are sealed, without gas leakage.
Claims (2)
1. gas-type engine air track, comprise: gas rail passage, electronic controlled gas injection mouth, support, bolt and O RunddichtringO, it is characterized in that: gas rail passage (1) is rectangular, below gas rail passage, each cylinder of corresponding gas engine is equipped with an air outlet (2), between air outlet and electronic controlled gas injection mouth (3), adopt O type circle (4) sealing, electronic controlled gas injection mouth is embedded in each cylinder intake manifold, gas rail passage is provided with support (5), and bolt for support (6) is connected and fixed with gas engine suction tude (7).
