will address natural gas engine emissions and efficiency improvements by developing a natural gas specific combustion design utilizing optimized in-cylinder charge motion and cooled exhaust gas recirculation (EGR). This research will enable development of mono-fuel natural gas internal combustion engine technology. Cummins Inc.

Advanced combustion modes for internal combustion engines have drawn much attention from researchers due to their com- bination of advantages relative to traditional spark-ignition (SI) and compression-ignition (CI) engines. . In the experiments, the researchers used a 425 cm 3 single-cylinder engine based on a GM/Isuzu 1.7
