Abstract

To improve the accuracy of ratio control systems for control of air-fuel flow rate in combustors and internal combustion engines, etc., a new ratio control system with a fuel control device directly connected to an air flow metering element is presented in this article. A valve in a bypass air passage is controlled to keep the signal of the air flow metering element in the passage constant. The air flow rate is directly transfered to the stroke of the valve which is connected to a fuel control device. The characteristics of the system in steady and transient conditions was clarified.
