In order to study the feasibility of the low load cycle (LLC) condition applied to China’s heavy-duty trucks, this paper selects a China Ⅵ heavy-duty trucks with 100% load to study the pollutant emission and driving condition characteristics of LLC, C-WTVC and CHTC-HT on chassis dynamometer. Vehicle specific power (VSP) is adopted as analysis method. The results show that the emission of pollutants (NOX, PN, CO2) under LLC cycle is higher than that under C-WTVC and CHTC-HT. the NOx emission and PN emission of the LLC are about 1 order of magnitude and 3 orders of magnitude higher than those under C-WTVC and CHTC-HT respectively. Compared with C-WTVC and CHTC-HT, CO2 emission of the LLC has the highest total emission performance, while the average emission rate of each VSP interval has the lowest performance, about 3.7g/s.
Key words: Low Load Cycle / Emission characteristic / VSP
