METHOD FOR CONTROLLING FUEL INJECTION FOR A DUAL FUEL ENGINE

摘要

A fuel injection system including injectors for two different fuels is disclosed. In one example, fuel injection is adjusted to compensate for changes in engine intake air amount. Combustion stability during transient conditions may be improved.

1. An engine operating method, comprising:
during a transition where EGR changes greater than a threshold:
increasing an amount of a first fuel with a first reactivity injected to a cylinder in response to an engine intake oxygen concentration error; anddecreasing an amount of a second fuel with a second reactivity injected to the cylinder in response to the engine intake oxygen concentration error; andcompression igniting the first and second fuels in the cylinder.
