The potential of using MCCT to reduce NOx emissions in a light-duty diesel vehicle was investigated in this study, focusing on the WLTC and RDE driving cycles. The MCCT function was activated by calibrating factor maps, and the relationship between electronic control unit signals and NOx emissions was analyzed. Results showed that MCCT could achieve varying degrees of reduction in engine-out and tail-pipe NOx emissions in both the WLTC and RDE cycles.
The potential of a method of transient control of model-based engine charge control (MCCT) is investigated to minimize nitrogen oxide (NOx) emissions of a light-duty diesel vehicle over two driving cycles, the worldwide harmonized light-duty test cycle (WLTC) and real driving emission (RDE) cycle. The MCCT function was switched on by calibrating factor maps corrected for several parameters. In addition, the relationship between electronic control unit signals and nitrogen oxide (NOx) emissions was analyzed under the WLTC and RDE. The engine-out and tail-pipe NOx emissions in the WLTC and RDE could achieve varying degrees of reduction with MCCT.
