This study investigates nitric oxide (NO
x
) production in a spark-ignited, internal combustion piston engine under oxy-combustion conditions. An engine has been modified for oxycombustion operation, using either EGR or CO
2
working fluid. Three parametric studies were carried to study NO
x
production levels under oxy-combustion conditions: changing N
2
concentration, changing O2 concentration while leaving N
2
constant, and investigating different working fluids and compression ratios. It was found that under constant power conditions, NO
x
production varies linearly with N
2
concentration. Varying the oxygen concentration significantly altered the NO
x
production, though brake mean efficiencies of all cases were similar. CO
2
working fluid produced better power and lower NO
x
than EGR working fluid, however, both cases showed that with 3% N
2
, current regulatory NO
x
levels cannot be attained while maintaining a reasonable COV IMEP.
