"Liquid Fuel Consumption Limits for Light Commercial Vehicles" implemented in February 2008
Starting February 1, 2008, China will implement national fuel consumption limits for light commercial vehicles. This new standard introduces a two-tiered approach to reduce fuel consumption by approximately 10% across the industry. The "Limit of Fuel Consumption for Light Commercial Vehicles" (GB 20997-2007) was officially released by the National Standards Committee on July 19, 2007. It marks the first mandatory national regulation aimed at controlling fuel usage in this vehicle category.
According to Jin Y, the lead drafter and chief engineer from the China Automotive Research Center, the standard applies to vehicles with a total design mass under 3,500 kg, typically accommodating 9 to 12 passengers. These vehicles are also used for cargo transportation. The two-stage fuel limit is set based on different engine displacements and maximum design masses. Starting from February 1, 2008, newly certified models and their variants must meet the second stage requirements. By January 1, 2009, all previously certified models must comply with the first phase, and by 2011, all applicable vehicles must meet the second stage standards.
The standard sets separate fuel consumption limits for both gasoline and diesel-powered vehicles. For example, light commercial vehicles with a maximum design mass between 2,000 and 2,500 kg, using gasoline with a displacement of 1.5 liters or less, are limited to 9 liters per 100 km in the first phase, and 8.1 liters in the second. In total, the standard includes 33 groups and 66 specific fuel consumption limits.
China's light commercial vehicles have significant potential for fuel efficiency improvements. To develop this standard, the China Automotive Technology and Research Center conducted extensive research, including evaluating the fuel consumption system, surveying domestic fuel use, and analyzing statistical data. The findings indicate that the first phase is relatively lenient, with most current models already meeting the requirements. The second phase tightens the limits by 5% to 10% compared to the first.
This standard plays a crucial role in supporting the Energy Conservation Law. Its implementation is vital for advancing national energy-saving initiatives, promoting technological improvements in vehicle energy efficiency, and strengthening China’s automotive energy standards framework. Overall, it represents a key step forward in the country’s efforts to reduce emissions and improve environmental sustainability.
