Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
It is noted that the parameters of a fuel metering valve are usually nonlinear, while classical linear analysis methods can be only used to analyze and optimize linear hydraulic control systems, which prevents the usage of linear analysis methods to study the effect of various parameters. In this paper, the flow rate of fuel metering valve is linearized using a flow gain(G), which optimized linkage to reconcile the linearized approach with the implementation of the nonlinear physical design. In particular, the relationship of steady-state flow gain and a shape of the flow orifice, including triangular, rectangular, and circular, are discussed. The result shows that triangular and circular shapes provide an excellent flow orifice compared to rectangular shape in the same of size and operation conditions.
