Title:
燃料噴射制御装置
Document Type and Number:
Japanese Patent JP5333464
Kind Code:
B2
Abstract:
The fuel injection control device has an asymptote-calculator, which calculates a decreasing asymptote by approximation of a decreasing curve course of a pressure curve course, and calculates an increasing curve course of the pressure curve course during pressure curve course. The decreasing curve course drops-out in a degradation period, in which the detected pressure is reduced corresponding to an increase of injection rate and the increasing curve course increases during an increasing period, in which the detected pressure is increased corresponding to a decline of injection rate.
