GASEOUS FUEL INJECTION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To enable a gaseous fuel injection control device to be applied for controlling an injection timing of gaseous fuel at an engine showing various layouts.SOLUTION: A gaseous fuel injection control device of this invention comprises: a stage calculating part for calculating a stage that is a period where one cycle of an engine for igniting gaseous fuel is divided for every cycle; and a gaseous fuel injection starting timing calculation part for calculating a stage for starting injection of gaseous fuel and a time ranging from the stage starting to the gaseous fuel injection starting on the basis of a gaseous fuel injection finish timing from a gaseous fuel injection valve toward a cylinder, an engine speed of the engine and a gaseous fuel injection time toward the cylinder.
