PURPOSE:To have an operation of a Diesel engine with good efficiency at all times by sensing the time of ignition delay according to the number of revolutions of engine, the injection and period of the fuel and by controlling the starting timing for fuel injection on the basis of the result of sensing. CONSTITUTION:In this fuel injection control device I , an injection pressure controller PC and an injection period controller TC receive a number-of-revolutions information N from a rotation meter TG and a crank angle information CA from a crank angle sensor CAD and determine thereupon the optimum timing and injection pressure in compliance with the injection amount command information q given by a governor belonging to the engine EN. Here a group of patterns are generated by a ignition delay time pattern group generator PG required according to the abve-mentioned number-of-revolutions information N, and this group is sent to an ignition delay time sensor FD, to know the time of ignition delay on the basis of information t, p given from controllers PC, TC. The output therefrom is used to control the injection timing controller T. |
