Fuel injection control device for a spark ignition engine with a fuel injector for injecting fuel directly into the cylinder

摘要

A fuel injection control device for a spark ignition engine with a fuel injector for injecting fuel directly into the cylinder is disclosed. The device comprises a determination mechanism for determining that the temperature of the injection hole of the injector is higher than a predetermined temperature. A controller controls the fuel injection such that a required amount of fuel is injected after the fuel pressure is dropped when the determination mechanism determines that the temperature of the injection hole of the injector is higher than the predetermined temperature.
