Title:
An engine fuel injection control device
Document Type and Number:
Japanese Patent JP5928380
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To correct deviation of a fuel injection amount due to pulsation of a fuel injection pressure.SOLUTION: A correction item is set on at least one of attenuation vibration model type amplitude, attenuation coefficient, frequency and phase relating to a variation characteristic of an injection deviation amount applied as the reference on which a pulsation waveform of a fuel injection pressure generated by pre-injection is reflected, and the correction item is changed according to the variation of injecting conditions of a combustion cycle to determine the variation characteristic of the injection deviation amount, and to correct a post-injection amount on the basis of the variation characteristic.
