Fuel injection device for controlling electromagnetic valve of four-cylinder diesel engine of vehicle, has reading process termination determination unit determining whether control unit terminates implementation of reading injection

摘要

The device has a deviation evaluation unit i.e. electronic control unit (40), for evaluating deviation of actual injection quantity based on actual injection quantity of each reading injection that is estimated by an injection quantity estimation unit. A reading process termination determination unit determines whether the electronic control unit terminates the implementation of reading injection based on the deviation that is evaluated by the deviation evaluation unit and target accuracy of the deviation.
