Abstract
A fuel delivery system () comprises a variable displacement pump () for pressurizing fuel. The variable displacement pump has a distinct first pump displacement setting for a first desired mass flow of fuel and a distinct second pump displacement setting for a second desired mass flow of fuel. The variable displacement pump operates in only one of the first and second pump displacement settings. A fuel control () with a metering valve downstream of the variable displacement pump selectively regulates fuel delivery.
