This paper presents a successful implementation of a hydraulic actuator for dynamically adjusting the advance angle of diesel fuel supply and its implementation of real-time control of the injection timing micro-computer control system. The system is especially suitable for diesel engines operating in variable working conditions and at the same time can be used for on-line control of diesel engine oil supply advance angle performance test. The control device has the advantages of simple structure and good manufacturability. This paper introduces the working principle and design essentials of the system in more detail, and gives the relevant experimental results.
