An investigation into the use of fluidic devices as gas fuel injectors for natural gas engines
thesis
posted on 2011-05-24, 14:20 authored by Q. Huang, Rui ChenA novel gas fuel injector system based on
the use of monostable fluidic devices is described in this paper. The proposed system consists of
non-moving-part fluidic devices which are capable
of operating in a Pulse Width Modulated (PWM)
control mode and of handling a large amount of
gas flow for engine operations. The system also
includes an electro-fluidic interface for fluidic
switching and air-gas mixing nozzles for better
mixing quality.
Two prototype fluidic injector units were
produced and their steady-state and dynamic
characteristics were evaluated on a laboratory test
rig. The results were compared with those from
several commercial gas injectors and it was found
that the fluidic injector has a faster dynamic
response and a smaller cycle-cycle variations.
