FUEL SUPPLY CONTROL DEVICE AND CONTROL METHOD FOR ENGINE

摘要

In an engine that includes a liquid fuel injector (3) and a gaseous fuel injector (4) connected to an intake pipe (2) via a fuel passage (5) and that switches fuel supplied into intake air between liquid fuel and gaseous fuel, an electronic control unit (6) increases fuel in an amount required to fill the fuel passage (5) with gaseous fuel at the time of initial fuel injection from the gaseous fuel injector (4) after switching from liquid fuel to gaseous fuel.
