Document Type and Number:

WIPO Patent Application WO/2017/047248

Kind Code:

A1

Abstract:

The objective of the present invention is to form a highly uniform air-fuel mixture not influenced by the engine rotational frequency. Therefore, the present invention is a fuel injection control device equipped with air cylinders, a first injector arranged in the upper part of the air cylinders in the axial direction and the center part in the radial direction, an intake valve arranged in the upper part of the air cylinders in the axial direction and the outside of the first fuel injection device in the radial direction, and a second injector that supplies fuel from the upper part of the air cylinders in the axial direction and the outside of at least the intake valve in the radial direction, said fuel injection control device being characterized in that, when the rotational frequency of the engine is high, the ratio of the amount of fuel supplied by the first injector to the amount supplied by the second injector is controlled so as to be greater than when the rotational frequency of the engine is low.
