Abstract

Based on a TGDI vehicle that would be upgraded to meet China Ⅵ emission standard, the real driving emission tests with and without GPF were conducted through the portable emission measurement system to study the influence of GPF on real driving emission. The results show that GPF can effectively filter PN emission, especially at low speed and high load engine operating conditions. PN emission can reduce by two orders of magnitude and PN capture efficiency is more than 99%. For TGDI vehicles, GPF can reduce PN emission of real driving total emission by over 95%. Therefore, GPF is the key aftertreatment device for this type of vehicle to meet China Ⅵ emission test. During the upgrading process from China Ⅴ to China Ⅵ, the only upgrading of GPF may cause the deterioration of other pollutants such as NO_x emission. For this vehicle, GPF affects the catalyst temperature during the real driving emission test and hence NO_x emission of total process increases.
