Abstract

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 CO₂ working fluid. Three parametric studies were carried to study NO_x production levels under oxy-combustion conditions: changing N₂ concentration, changing O2 concentration while leaving N₂ constant, and investigating different working fluids and compression ratios. It was found that under constant power conditions, NO_x production varies linearly with N₂ concentration. Varying the oxygen concentration significantly altered the NO_x production, though brake mean efficiencies of all cases were similar. CO₂ working fluid produced better power and lower NO_x than EGR working fluid, however, both cases showed that with 3% N₂, current regulatory NO_x levels cannot be attained while maintaining a reasonable COV IMEP.
