Control method for dual injector of engine

A method for controlling a plurality of injectors installed in a cylinder of an engine for supplying fuel to the cylinder, the cylinder requiring an amount of fuel to be injected by the injectors, the method comprising:

• determining whether an electrical failure has occurred in any injector of the plurality of injectors;
• and
• entering a fail-safe mode when an electrical failure has occurred in one of the plurality of injectors,
• wherein in the fail-safe mode fuel supply is cut off to the injector that has experienced an electrical failure, and an amount of fuel injected into the cylinder by a normally operating injector is increased, and
• wherein entering the fail-safe mode further comprises:
• determining the cause of the electrical failure;
• and
• depending on the cause of the electrical failure, deciding whether to cut off the fuel supply to the injector that has experienced an electrical failure and to perform injection control for that injector.
