The design and realization of regulation subsystem for the air-fuel ratio of gas generators

This paper gives an introduction about the design of an intelligent air-fuel ratio regulation subsystem based on DSP for low-caloric gas generators. According to the variation of air-fuel ratio and running speed, the subsystem can regulate the gas and air supply properly and implement the self-adapting tuning of the gas and air supply under different caloric conditions along with the accurate control of the running speed of a generator, thus improving the efficiency of the gas generator. Experimental results showthat the subsystem is of practical value.
