Description
Technical field
The utility model relates to a kind of Fuelinjection nozzle of natural gas engine.
Background technique
The fuel metering device of current domestic natural gas motor has pressure to regulate and Timing control mode two kinds, namely pressure regulable control mode regulates the gaseous-pressure after measuring apparatus by controlling injection valve aperture size, and then adjustment of combustion gas flow, namely Timing control mode carrys out adjustment of combustion gas flow by the opening time of control valve.Because gas flow during employing Timing control mode is subject to the impact of gaseous-pressure and temperature, not only integrated nozzle is needed in injection valve, also to measure gaseous-pressure and the temperature of injection valve inlet, and the mode such as the how general employing welding of Timing type injection valve at present and casting, there is cost high, low precision, installs inconvenient problem.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Fuelinjection nozzle new for natural gas engine, and combined by machined part, cost is low, and precision is high, easy to use.
The technical solution of the utility model is, a kind of Fuelinjection nozzle of natural gas engine, comprise upper valve body, lower valve body, temperature and pressure transmitter, nozzle, air input joint, spacer, air outlet adapter, fixing bolt, electric interfaces, nozzle is between upper valve body and lower valve body, the bottom of upper valve body and the top of lower valve body are equipped with nozzle mounting hole, nozzle is arranged in the nozzle mounting hole of upper valve body and lower valve body, nozzle mounting hole respectively with upper valve body inner chamber runner and lower body cavity runner through, upper valve body and lower valve body are fixed connection by fixing bolt, two valve body spacings are determined by spacer between upper valve body and lower valve body, temperature and pressure transmitter and air input joint are installed on lower valve body, air outlet adapter is installed on upper valve body, electric interfaces is positioned on nozzle.
The natural gas engine Fuelinjection nozzle that the utility model proposes, adopts the manufacture of machine machining process, avoids different engine gas traffic demand and adopts the modes such as welding and casting, save multiple kinds of molds expense, low cost of manufacture, controls fuel spraymeter accuracy of measurement high, easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 2.
In figure, 1 is upper valve body, and 2 is nozzle, and 3 is temperature and pressure transmitter, and 4 is lower valve body, 5 is air input joint, and 6 is spacer, and 7 is fixing bolt, and 8 is air outlet adapter, 9 is electric interfaces, and 10 is nozzle mounting hole, and 11 is upper valve body inner chamber runner, and 12 is lower body cavity runner.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, 2, shown in 3, a kind of Fuelinjection nozzle of natural gas engine, comprise upper valve body 1, lower valve body 4, temperature and pressure transmitter 3, nozzle 2, air input joint 5, spacer 6, fixing bolt 7, air outlet adapter 8, electric interfaces 9, upper valve body 1 and lower valve body 4 are made up of aluminum alloy machinery processing method, the bottom of upper valve body 1 and the top of lower valve body 4 are equipped with 4 nozzle mounting holes 10, 4 nozzles 2 are arranged in the nozzle mounting hole 10 of upper valve body 1 and lower valve body 4, nozzle mounting hole 10 respectively with upper valve body inner chamber runner 11 and lower body cavity runner 12 through, upper valve body 1 and lower valve body 4 are fixed connection by two fixing bolts 7, two valve body spacings are determined by spacer 6 between upper valve body 1 and lower valve body 4, temperature and pressure transmitter 3 and air input joint 5 are installed on lower valve body 4, air outlet adapter 8 is installed on upper valve body 1, electric interfaces 9 is positioned on nozzle 2, nozzle 2 space between each other is 22-36mm, determine that upper and lower valve body spacing is 20-45mm by spacer 6, upper and lower valve body is furnished with altogether the nozzle mounting hole that 8 diameters are 6-10mm, for installing 4 nozzles.
When natural gas engine adopts Timing mode to control gas flow, rock gas is full of lower body cavity runner 12 by air input joint 5, gas pressure in the lower valve body 4 of fuel gas temperature pressure transducer 3 measurement and temperature, opening time under certain gas flow needed for nozzle 2 is calculated by reading gas pressure and thermometer by control unit of engine (ECU), then control unit of engine (ECU) is by the opening time of electric interfaces 9 Control Nozzle 2 of nozzle 2, thus make the rock gas of certain flow enter upper valve body inner chamber runner 11, realize natural gas flow measuring and the control of injection valve, final rock gas flows out injection valve by air outlet adapter 8.
The natural gas engine Fuelinjection nozzle that the utility model proposes, adopt and formed by machined part Combination of Methods, avoid different engine gas traffic demand and adopt the modes such as welding and casting, save multiple kinds of molds expense, low cost of manufacture, control fuel spraymeter accuracy of measurement high, easy for installation.
