Abstract
Official abstract text for this publication.
A control device for direct injection gasoline engines includes a fuel injection control part (engine control device) composed to control a fuel injection aspect of an injector. The fuel injection control part changes an injection mode of the injector by changing the lift amount of the injector and the injection interval of the fuel respectively. The fuel injection control part switches between a first injection mode, which includes multiple times of the fuel injection with the small lift amount of the injector and the small interval of the fuel injection, and a second injection mode, which includes multiple times of the fuel injection with the bigger lift amount of the injector and the larger interval of the fuel injection than those of the first injection mode, according to an operating state of the engine body.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control device for a direct injection gasoline engine comprising: an engine body having a cylinder; and an injector for injecting fuel including at least gasoline into the cylinder and being configured so that the larger a lift amount of the injector is, the larger a fuel injection opening area of the injector becomes; the control device comprising: a fuel injection control part executed on a microprocessor and configured to control the injector…
