Electronically controlled fuel injection system for a diesel engine

摘要

A fuel injection control apparatus reduces an error in the fuel injection amount when a prediction correction is preformed. A target closing time and a target opening time of a spill valve (23) are corrected based on a difference in rotational speed of an associated diesel engine (2) between a current cycle and a previous cycle. The prediction correction for the opening time of the spill valve (23) is performed only when it is determined that the prediction correction for the target closing time of the spill valve has been performed in the same cycle.
