What is the China V standard for regular diesel?

[VanJoshua]

The China V diesel standard is equivalent to the Euro V standard in the European Union. Below are relevant details about the China V standard: 1. Diesel quality standards: Anti-knock quality, volatility, fluidity, corrosiveness, and stability. 2. Differences between China V and China IV standards: From China IV to China V, the required cetane number increased from 49, 46, and 45 to 51, 49, and 47 respectively, and the cetane index at low temperatures rose from 43 to 46; the sulfur content in diesel decreased from 50ppm to 10ppm. Meanwhile, the China V standard achieves at least 10% and 7% reductions in nitrogen oxide emissions compared to the China IV standard. Emissions of hydrocarbons, carbon monoxide, nitrogen oxides, and particulate matter are all effectively controlled, directly reducing PM2.5 emissions in exhaust gases.
