In-cylinder charging system for fuel delivery systems and methods

摘要

An air charging system includes a valve providing access to an engine cylinder, an accumulator coupled in flow communication with the valve, and a controller operable to open and close the valve until a threshold pressure condition is reached in the accumulator. Compressed gases stored in the accumulator are used in a fuel delivery system to prepare a charge of fuel that is delivered to an engine.
