The effects of cyclic loads on the BSFC and NOx emissions of a CI engine are investigated. Compared to static loads, the largest deviations are 6.7% and 9.1%, respectively. For the quasi-steady estimations, the largest errors are 2.9% and 4.3%, respectively. The effects primarily depend on the average load level. The quasi-steady estimations show good results except for a low load with high frequency.
