ELECTRONICALLY CONTROLLED DIESEL ENGINE

摘要

Disclosed is an arrangement for preventing abrupt increase in fuel injection quantity from that before acceleration without previously measuring correlation of the number of revolutions of an engine, boost pressure, smoke limit fuel injection quantity, and the like.  An acceleration determination section (64) determines whether to finish acceleration control based on the difference between a target number of revolutions of an engine (Nset) and an actual number of revolutions of an engine (Ne).  When acceleration determination section (64) determines that low speed zone acceleration conditions are satisfied, a third upper limit injection quantity calculation section (73) constituting an upper limit injection quantity calculation section (65) sets an initial upper limit injection quantity (Q0) to the larger one of the injection quantity at the time of the determination or an upper injection quantity set for the actual number of revolutions of an engine (Ne) at the time of the determination, and returns the injection quantity to a normal upper limit according to the time elapsed until the acceleration determination section (64) determines that low speed zone acceleration release conditions are satisfied.
