Alternatively, still further, the fan may be eliminated from combustion chamber, and a fuel injection manifold and accelerator plate system may be disposed at {TAIL ~ an axial position} within the combustion chamber so as to effectively provide uniform injection and distribution of the fuel into the combustion chamber, as well as {HEAD ~ the formation} of turbulent conditions within the combustion chamber so as to ensure and maximize the mixing of the air and fuel components and the propagation of multiple flame fronts or jets within the combustion chamber
