Abstract
Official abstract text for this publication.
During a catalyst rapid warm-up at a time of a cold start of an engine, a fuel is injected by a required injection quantity through a multi-stage injection consisting of a fuel injection by a full lift injection during an intake stroke and a fuel injection by a partial lift injection during a compression stroke. In a case where a deterioration of a combustion state is confirmed, a correction for increasing the required injection quantity, which is to enrich an air-fuel ratio, is performed. At a time of the enriching quantity increase, a sum of injection quantities of the multi-stage injection is increased by the amount of the correction for increasing the required injection quantity without the injection quantity and an injection timing of the fuel injection by the partial lift injection being changed from a base time.
First claim
Opening claim text (preview).
What is claimed is: 1 . A control device for an engine, the engine including a fuel injection valve and the fuel injection valve having a valve body, the control device comprising an electronic control unit configured to: calculate a required injection quantity in accordance with an operation state of the engine; control the fuel injection valve such that a fuel is injected by the required injection quantity; and increase a sum of injection quantities of a multi-stage injec…
