Zusammenfassung:	PROBLEM TO BE SOLVED: To improve fuel efficiency by quickly estimating the effect of disturbance on a propeller and, based on the estimation, making corrections to governor control. SOLUTION: In this marine engine control system, the deviation between a rotation speed command and the actual measured rotation speed NEof a main shaft 13 or a main engine 12 is input into a PID computation unit 16, and the amount of fuel supplied to the main engine 12 from a fuel injection device 15 is controlled by feedback. The load torque QPon a propeller 14 is detected, and a governor command output from the PID computation unit 16 to the fuel injection device 15 is corrected. COPYRIGHT: (C)2011,JPO&INPIT
