Integrated powertrain control to meet low CO2 emissions for a hybrid distribution truck with scr-denox system
conference paper
This article presents a cost-based optimization strategy that explicitly deals with the requirements for fuel consumption and emissions. Based on the Integrated Powertrain Control (IPC) approach, the overall powertrain performance is optimized by integrated energy and emission management. The potential of this strategy is demonstrated for a parallel hybrid diesel truck with a Selective Catalytic Reduction (SCR) de-NOx system. New results are presented for a challenging city cycle; although the average power demand is low, IPC is able to keep the SCR catalyst temperature relatively high. With this IPC approach, the CO2-NOx trade-off is optimized in a systematic way. It is demonstrated that CO2 emissions and related operating costs are reduced by 3.5% or 24.9% NOx emission reduction is achieved, depending on the applied IPC calibration. Copyright © 2011 by ASME.
