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 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.
