Abstract
A novel piezo-fluidic gaseous fuel injector system designed for natural gas engines is described in this paper The system consists mainly of no-moving-part fluidic devices and piezo electro-fluidic interfaces The steady state and dynamic characteristics of the system were tested on a laboratory experimental rig The results show that the system can handle the large gas volume flow rate required by natural gas engines and is capable of operating via pulse width modulation. A few typical commercial solenoid type gas injectors were also tested and the results were compared with those from the piezo-fluidic injector system. It was found that the piezo-fluidic gaseous fuel injector system has faster switching responses and smaller injection cycle-to-cycle variations
