FUEL SUPPLY CONTROL DEVICE FOR ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a fuel supply control device of an engine capable of supplying an appropriate amount of fuel during air intake even at a first fuel injection from an injector connected to an intake pipe through a fuel passage.

SOLUTION: The engine is provided with a liquid fuel injector 3 and a gaseous fuel injector 4 connected to the intake pipe 2 via a fuel passage 5, and switches the fuel supplied during air intake between the liquid fuel and gaseous fuel. An electronic control unit 6 increases and corrects the amount of fuel required to fill the fuel passage 5 with the gaseous fuel at the first fuel injection of the gaseous fuel injector 4 after switching from the liquid fuel to the gaseous fuel.
