  • In this research, engine OM 364 LA, made in IDEM Co. was studied. Engine emissions include CO, NOx and UHC were tested using ISIRI 6764 standard (ECE-R49) and ESC test cycle. The test cycle consisted of 13 steady states in the different range of rpm and loads (25 to 100 %). the goal was experimentally study on the effects of injection retard on NOx emissions and engine performance. The results indi-cated a 65% reduction in NOx emissions but at the cost of a 14% reduction in engine power. Although the overall results indicate a drop in performance and a reduction in engine thermal efficiency due to injection retard but in contrast, there is a significant improvement and reduc-tion of NOx emission.
