Abstract
Methods are provided for improving delivery of supercritical fuels via a direct injector. An injector control parameter is adjusted based on one of a fuel pump gain, an injected fuel mass, or a change in pressure in the fuel rail, and the engine operates the injector based on the adjusted parameter. Injector control parameters are only adjusted when fluid is subcritical at the fuel pump and when injector overlap is not present.
