Injection rate controller for internal combustion engine

摘要

By closing or opening an SPV (electromagnetic valve for metering) (2) at a position advanced from cam lift start only by an amount of a pre-stroke value based on a timer position error between a target timer position or an actual timer position just before the switching control and an actual timer position at the time of a shift from the non-pilot injection control to the pilot injection control, a retard angle state at the injection timing is eliminated. By closing or opening the SPV (2) at a position delayed from cam lift start only by an amount of a pre-stroke value in accordance with a timer position error between a target timer position and an actual timer position after the switching control at the time of shift from the pilot injection control to the non-pilot injection control, a retard angle state at the injection timing is eliminated. <IMAGE>
