GPF Filtration Performance under Different Operation Conditions

摘要

GPF filtration performance with different operation conditions were evaluated: 1. Even under RDE, GPF can effectively reduce PN emissions below regulation limit. 2. Higher FE can be obtained by larger volume of GPF: (1) Appropriate GPF volume can be determined based on application. 3. Impact of raw emissions and GPF positions were investigated. 4. No measureable CO_2 emissions impact has been found under NEDC, WLTC and Artemis with GPF.
