Document Type and Number:
Japanese Patent JP2910557
Kind Code:
B2
Abstract:
PURPOSE:To execute high precise supercharging pressure control processing prevented from the occurrence of hunting, in a fuel injection control device for a diesel engine which has both a means to control a supercharging pressure and a means to control a fuel infection timing. CONSTITUTION:A fuel injection control device for a diesel engine with a supercharger comprises a supercharger A2; a fuel injection means A3 to forcibly feed fuel to a diesel engine A1 to effect injection of fuel; a supercharging pressure control means A4 to control a supercharging pressure so that a supercharging pressure of intake air boosted by the supercharger A2 is adjusted to a given target supercharging pressure set according to the operation state of the diesel engine A1; and a fuel injection timing control means A5 to control a fuel injection timing so that a fuel injection timing is adjusted to a given target injection timing set according to the operation state of the diesel engine A1. Further, a supercharging pressure correction means A6 is provided to correct a supercharging correction amount of the supercharging pressure control means A4 according to a correction value being a target fuel injection timing and an actual fuel injection timing so as to execute control of a fuel injection timing.
