In order to solve the problem of cold start fuel flow control of an aero-piston engine fueled by kerosene

a fuel film compensation model based on fuel film theory was presented

and a discrete control algorithm running on microcontroller was given.What's more

a fuel flow control model for cold start which was based on fuel film compensation was simulated on Matlab/Simulink platform.The simulation result shows this control model can ensure sufficient kerosene flowing into the cylinder.Finally

the prototype burning kerosene experiments were performed

which shows that without changing fuel feeding and ignition system

the cold start capability of kerosene engine has been improved by cold start fuel flow control.
