Title:
FUEL INJECTION CONTROL DEVICE AND PRESSURE ACCUMULATION TYPE FUEL INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/125371
Kind Code:
A1
Abstract:
Provided are a fuel injection control device and a pressure accumulation type fuel injection device such that an actual fuel injection amount is controlled to a target fuel injection amount without extending the injection time to an amount not less than the injection time based on a base injector. The fuel injection control device is equipped with a target injection amount computing means for computing the target fuel injection amount; a target rail pressure computing means for computing a target pressure in a common rail; a rail pressure detection means for detecting the pressure in the common rail; a rail pressure control means for controlling the pressure in the common rail; a memory means for storing basic injection amount map information prepared using the base injector; a correction means for correcting the target pressure or the control amount by the rail pressure control means, on the basis of the difference between the injection rate characteristics of the base injector and the injection rate characteristics of the injector; and an injector control means for obtaining energization time on the basis of the basic injection amount map information, and executing injector drive control.
