Abstract
A dual fuel engine system, such as for diesel and natural gas operation, includes a control system having an electronic control unit structured to vary a stored control valve for a fuel delivery parameter, responsive to engine power output. The engine power output can be determined by in-cylinder pressure monitoring during a liquid fuel mode. The stored control value can be a dynamically updated value in an engine fueling map.
