In order to realize the rapid development and strategy verification of the two-stroke kerosene aviation engine controller

in combination with the rich software and hardware resources of the MotoTron rapid control prototype development platform

based on the system design requirements of air-assisted direct injection and dual-spark plug ignition

an engine controller for controlling the four-cylinder engine using an eight-cylinder program was developed. The design method of control software based on the rapid control prototype software architecture was analyzed

and the development software

MotoHawk was used to configure the underlying program and build the engine control system. Then

in combination with Matlab/Simulink

the upper control strategy was established to completely develop the whole control system. The cold start bench tests were carried out

during which the speed of the engine was stable

the adjustment processes of the ignition advanced angle

the injection advance angle and the injection pulse width were in accordance with the control strategy. And the air-fuel ratio control was stable

with the error within 10%. The smooth transitions of the engine to normal conditions verified the cold start control strategy. And the fundamental functions of the controller had been realized

showing that the controller design could meet the requirements.
