5.4. Discussion
6. Topics for discussion
6.1. General comments on HDH work program
HDH-15-08/Rev.1 | Influence of WHVC Compensation Method on Emission Test Results: Revised Since the system output is different between WHTC, the test cycle for conventional vehicles, and WHVC, a compensation method has been proposed.
