System and method for injecting fuel to an engine
Abstract:
Methods and systems are provided for accounting for a difference between an expected amount of fuel scheduled to be delivered and an actual amount of fuel delivered to an engine cylinder during a fueling event. In one example, a method may include scheduling a direct injection to a cylinder based on an estimated expected amount of fuel injected to the cylinder during an immediately previous injection event. The expected amount of fuel injected during the immediately previous injection event may be a function of an average fuel rail pressure during the immediately previous injection event.
