The smallest indicated specific NOx emission value is obtained with no hydrogen and with 11% H2 and 17% H2
content, a significant increase in NOx formation is observed. At 30% H2 and 42% H2 contents, the increase in
NOx formation is measured as 226.14% and 305.75%,respectively. Formation of NOx is associated with the incylindrical
temperature rise, oxygen concentration and reaction duration
