ABSTRACT:
A fuel injection timing control system for an internal combustion engine into which fuel is intermittently injected, includes a closed-loop fuel injection timing control system, a first device, fluidly-driven, for varying the fuel injection timing, and a second device for adjustably determining the response time and the stability of the closed-loop control system. The first device constitutes a part of the closed-loop control system. The second device constitutes another part of the closed-loop control system. Sensed is a condition of the working fluid for the first device which can influence the response time and the stability of the closed-loop control system. The second device is adjusted in accordance with the sensed working fluid condition so as to reduce the influence of the working fluid condition on the response time and the stability of the closed-loop control system.
