Abstract
In order to reduce vehicle carbon emissions, the Chinese government is drafting new fuel consumption limits standard for heavy commercial vehicles. The standard will adopt new test method, which will have an impact on the results of vehicle fuel consumption. This paper compares the differences between C-WTVC and CHTC, and theoretically evaluates the impact of vehicle fuel consumption. In addition, the impact is empirically analyzed through the actual vehicle test. It is found that the heavy truck switching from C-WTVC to CHTC-HT will increase the fuel consumption by 0.2%-7.6%, and there is a positive correlation between vehicle fuel consumption and gross vehicle weight (GVW). Among them, the increase of fuel consumption is more obvious in the low speed and high speed parts of the test cycle. In order to achieve fuel consumption compliance, enterprises need to focus on low-speed and high-speed fuel consumption performance.
