Abstract:
An apparatus for the active control of the combustion rate of an air and fuel mixture in a combustion chamber of an internal combustion engine, including:a stationary flame speed control member having an external surface extending into the combustion chamber and defining at least a portion of the wall of the combustion chamber adjacent to a portion of the combustion chamber where control of the flame speed of a combustion event in the combustion chamber is desired; a means for modulating the temperature of the external surface of said flame speed control member; and a control means for controlling said means for modulating the temperature of the external surface of said flame speed control member in response to sensing at least one operating parameter of the internal combustion engine; wherein the external surface of said flame speed control member extending into the combustion chamber is a protuberant surface having a surface passageway in fluid communication with said means for controllably modulating the temperature of the external surface of said flame speed control member.
