Abstract:
A method for an engine with first and second injectors in a cylinder provides different fuel injection compensation upon reaching minimum pulsewidths of the first and second injectors. When the first injector reaches its minimum pulsewidth, the first injector is disabled. However, when the second injector reaches its minimum pulsewidth, the second injector is maintained active and injection from the first injector is decreased. In this way, sufficient injection from the second injector is maintained in either situation.
