Description

A urea SCR system was combined with a DPF system to reduce NOx and PM in a 4L turbocharged with intercooler diesel engine. Urea injection control logic was developed for various low temperature and high temperature transient operations. Significant reductions in NOx were realized in JE05 and WHTC modes by adopting the urea injection control. It has been shown that NOx can be reduced by 95%, achieving the challenge target value of NOx in JE05 mode.
