摘要

In this study, a procedure was applied for the performance of real-time emissions measurement at engine transient tests. The measurement of gaseous emissions from raw exhaust was done according to the standard ISO16183:2002 and the particulate mass emission was determined by an alternative method based on the measurement of smoke opacity and hydrocarbon emission during the transient test for further conversion to particulate mass. The method for calculating particle mass was validated by comparison with experimental data obtained by application of the standard gravimetric method.
