Abstract：To automatically detect the sealing performance of gas injection component assembly in natural gas engine,an automatic testing platform for gas injection component assembly has been developed.The main functions and testing parameters of the testing platform are clarified,the hardware acquisition board circuit modules,including power supply circuit,nozzle drive circuit,communication circuit,and signal acquisition circuit is designed,the software system of the testing platform is developed based on Lab VIEW,the monitoring interface is designed using a multi-threading and C++mixed programming methods,and practical application verification is carried out in a gas injection component production workshop.The actual application results show that the automatic testing platform can effectively test the sealing performance of multiple gas injection components with different numbers of nozzles,quickly and intuitively display the testing process,real-time collect information during nozzle testing,and judge the working status of each nozzle and sensor.The automatic testing platform has excellent practicality and reliability,improves the production efficiency of gas component assemblies,and reduces the product costs.
