Current situation and development trend of automobile diesel standards in China.

This paper describes the evolution course of automotive diesel standards in China, and briefly analyzes the current situation, then summarizes the development trend of their seven important technical indexes, finally analyzes the reasons of their continuous improvement. Automotive diesel standards have been developing straight forward the direction of clean oil. Compared with EU, USA and Japan, automotive diesel standards relatively lag behind others in China, so it is imperative to improve the quality of the product. The heavy and inferior properties of the crude oil process, the low production capacity of installations, and the lack of competitive catalysts have limited the upgrading of diesel quality in China. Based on the above reasons, a new automotive diesel standard will be prospected, namely formulating automotive diesel standard in line with China's national conditions, giving appropriate financial subsidies to refineries, supervising the implementation of automotive diesel fuel in China, developing and popularizing the core technology of diesel production.
