Abstract: With the rapid development of China's automobile industry, the vehicles population continues to rise, of which the total number of heavy-duty commercial vehicles with a long annual mileage have brought more prominent energy shortage and environmental pollution problems. By combing and analyzing the fuel consumption limit standard of heavy-duty commercial vehicles issued by the state, it can be found that China's fuel consumption measurement method is gradually tightened, and the fuel consumption limit is getting lower and lower. At this stage, there is still a gap with the advanced level of foreign countries, and it is expected that the next stage will reach the international leading level. With the increasingly strict fuel consumption limits of heavy-duty commercial vehicles, this will accelerate the transformation and upgrading of the heavy-duty commercial vehicle industry, improve the fuel economy of heavy-duty commercial vehicles, alleviate fuel supply contradictions, reduce exhaust emissions, improve the atmospheric environment, and promote the sustainable development of the heavy-duty commercial vehicle industry.
