In-use compliance evaluation for vehicles focuses on the emission limit standards of vehicles operating within the warranty period of emission reduction devices. In the case of heavy-duty vehicles, the in-service conformity(ISC) test is implemented by applying the portable emission measurement systems(PEMS) to the in-use compliance evaluation. In this study, the domestic RDE-HDV route was improved by reflecting the regulations proposed for the actual driving emissions evaluation of ultra-heavy-duty vehicles in Korea. Additionally, RDE-HDV tests were conducted with ultra-heavy-duty vehicles. As a result, in the developed RDE-HDV route, the averaged NOx emissions were sufficiently reflected in low-load engine operating conditions, including an engine power ratio of less than 20 %. Therefore, the emission characteristics of ultra-heavy duty vehicles were appropriately evaluated for the test trip consisting of urban, rural, and motorway driving parts. |
