Abstract
The invention discloses a high-precision performance tester for a vehicle fuel gas injection valve. The tester comprises a fuel gas injection valve arranged on a gas pipeline, a pressure sensor used for detecting the pressure at the gas inlet of the fuel gas injection valve, a temperature sensor used for detecting the temperature of the fuel gas, a controller used for controlling the fuel gas injection valve, and an electronic weighing device used for weighing the gas injected out of the fuel gas injection valve. The weighing precision of the electronic weighing device is 0.2 cc. According to the technical scheme of the invention, the high-precision performance tester for the vehicle fuel gas injection valve controls the injection operation and the injection time length of the fuel gas injection valve by means of the controller. Meanwhile, the injected gas is weighed by the electronic weighing device. Since the weighing precision of the electronic weighing device is 0.2 cc, the electronic weighing device is high in weighing precision. Therefore, the electronic weighing device is capable of accurately measuring the one-time instantaneous injection amount of the fuel gas injection valve. As a result, the performance test quality of the fuel gas injection valve is greatly improved.

Technical field
The present invention relates to fuel gas injection detection technique field, the single discharge rate particularly to a kind of fuel gas injection valve is examined
Measurement equipment.
Background technology
The inspection of automotive natural gas nozzle performance needs to detect its jet velocity and instantaneous emitted dose, but due to spray
Time of penetrating is short, and emitted dose is little, and traditional gas meter cannot meet the testing conditions of its harshness, certainty of measurement
It is unable to reach requirement.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of vehicle fuel injection valve high precision performance tester, with
The effusion meter solving existing detection automotive natural gas nozzle performance can not meet the skill of instantaneous emitted dose testing requirement
Art problem.
Vehicle fuel injection valve high precision performance tester of the present invention, including the combustion gas being arranged on fuel gas pipeline
Injection valve, the pressure transducer of detection fuel gas injection valve inlet pressure, the temperature of detection fuel gas temperature pass
Sensor, the controller controlling fuel gas injection valve and the gas spraying fuel gas injection valve are weighed
Electronic weighing device, the weighing precision of described electronic weighing device is 0.2cc.
Beneficial effects of the present invention:
Vehicle fuel injection valve high precision performance tester of the present invention, it passes through the controller spray to fuel gas injection valve
Penetrating action and injecting time length is controlled, the gas of ejection is weighed by electronic weighing device, by
Weighing precision in electronic weighing device is 0.2cc, and weighing precision is high, therefore can accurately measure fuel gas injection
The instantaneous discharge rate of single of valve, it is thus possible to the biggest performance detection quality improving fuel gas injection valve.
Accompanying drawing explanation
Fig. 1 is the theory structure schematic diagram of the present embodiment vehicle fuel injection valve high precision performance tester.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As it can be seen, the present embodiment vehicle fuel injection valve high precision performance tester, including being arranged on combustion gas
Fuel gas injection valve 1 on pipeline, the pressure transducer 2 of detection fuel gas injection valve inlet pressure, detection combustion
The temperature sensor 3 of temperature, control the controller 4 of fuel gas injection valve and fuel gas injection valve is sprayed
Gas carry out the electronic weighing device 5 weighed, the weighing precision of described electronic weighing device is 0.2cc.
During work, temperature signal that controller detects according to temperature sensor and the pressure of pressure transducer detection
Force signal control fuel gas injection valve injection initial time and injection duration, and temperature, pressure, with
And measurement result is shown by display device, testing staff can know the parameters of test intuitively
Condition and test result, test operation is simple and convenient.
The present embodiment vehicle fuel injection valve high precision performance tester, the gas of ejection passes through electronic weighing
Putting and weigh, owing to the weighing precision of electronic weighing device is 0.2cc, weighing precision can reach 0.16
Milligram, weighing precision is high, therefore can accurately measure the instantaneous discharge rate of single of fuel gas injection valve, it is thus possible to the biggest
Improve fuel gas injection valve performance detection quality.
Finally illustrate, above example only in order to technical scheme to be described and unrestricted, although
With reference to preferred embodiment, the present invention is described in detail, it will be understood by those within the art that,
Technical scheme can be modified or equivalent, without deviating from technical solution of the present invention
Objective and scope, it all should be contained in the middle of scope of the presently claimed invention.
