| 抄録（英） | Plug-in hybrid electric vehicles (PHEVs) can effectively reduce fuel consumption and CO2 emissions, but the pollutant emission characteristics and engine operating conditions during high-power cold starts (HPCSs) are seldom reported. To fill this research gap, a blended PHEV was tested during worldwide light-duty test procedure (WLTC) and a new cycle was developed. The results in WLTC test indicated that two HPCSs occurred under charge depleting (CD) mode, while a convention cold start occurred under charge-sustaining (CS) mode. The particle number (PN) and NOx emissions during the HPCS were both higher than those of the conventional cold-start, but the CO and HC emissions were lower. The difference in emission characteristic of two kinds of cold starts was caused by the difference in engine operating conditions. During HPCSs, the engine speed and load increased dramatically to high level under the low temperature of coolant or three-way catalytic converter (TWC), while the engine idled for ~1 minute and then the engine speed and load increased slowly during the conventional cold start. The results in the developed cycle indicated that the PN emissions during HPCSs increased first and then decreased with the increasing coolant temperature. The PN emissions increased by 16% when the coolant temperature rose from ~20 ℃ to ~30 ℃, and the PN emissions decreases by 72% when the coolant temperature rose from~20 ℃ to ~60 ℃. 翻訳 |
