According to statistics, since 2000, the fuel consumed by engine-driven vehicles has occupied 50 percent of the country's total diesel consumption and one third of the total gasoline consumption. Meanwhile, in China's big metropolises, more than 80 percent of the carbon monoxide, 40 percent of the nitrous oxide, and 20 to 30 percent of the particulate matter, are from motor vehicles.

To improve the efficiency of China's internal combustion engines, the country's authorities have designed several standards and regulations to reduce the pollutants. Since 2007, all kinds of vehicles all over the country have begun using fuel that meets the China III emission standards. In March 2008, Beijing took the lead in implementing new China IV emission standards. Responding to the trend, new engines have been developed to meet the new, more stringent emission standards.
