【Abstract】Gas nozzle is a key component of gas engine to realize quantitative injection of gas fuel. In order to master the jet flow characteristics of gas nozzle， a flow detection system is designed and built， and the flow parameters of gas nozzle are measured successfully. The experimental results show that the system has high measurement accuracy， fully meets the measurement requirements， and is of high practical value in gas nozzle flow detection， consistency test， state judgment and other aspects.

【Key words】engine; gas nozzle; flow measurement
