Abstract
A cylinder head of an engine has a body, at least one recirculation chamber, and a flow control system. The body defines at least one orifice, and the recirculation chamber is in fluid communication with the at least one orifice. The flow control system has an inlet flow position and an outlet flow position. A method of operating an engine having at least one recirculation chamber and at least one combustion chamber containing a pressurized fluid includes transferring a portion of the pressurized fluid from the at least one combustion chamber to the at least one recirculation chamber when the pressurized fluid reaches a first predetermined pressure value. The method also includes transferring the portion of the pressurized fluid from the at least one recirculation chamber to the at least one combustion chamber when the pressurized fluid in the at least one combustion chamber reaches a second predetermined pressure value.
