The emission characteristics were compared by two different emission test cycles for heavy-duty diesel engines. One is ECE R-49 test cycle and the other is ESC. In order to investigate the performance of both test cycles, a heavy-duty diesel engine for a city bus was used with and without after-treatment device. Smoke opacity was also measured to observe the instantaneous smoke value for both test cycles. It was found that more gas emissions produced in ECE R-49 test cycle while more PM created in ESC test cycle without DPF. Smoke opacity was proportional to the engine power and had higher values in the ESC test cycle.
