Abstract: Systems, devices, and methods are provided for improving fuel distribution in gas fired reciprocating internal combustion engines (RICE) that use direct inject fuel gas injector systems. The systems, methods, and devices facilitate directing fuel flow into a combustion chamber of the engine, which can create a more homogenous fuel/air mixture, resulting in more efficient combustion and a reduction in NOx, volatile organic compounds (VOCs), and carbon monoxide (CO), emissions.
