Chinese car signs up for the car that asks to study contented country Ⅳ is discharged to taste a standard with oil, make sure car tail gas is discharged can stabilize reach a nation Ⅳ discharges a standard, orgnaization of scientific research of much home of organization of Beijing committee of science and technology was begun " the clean fuel that contented country Ⅳ discharges a standard and the research that discharge a relation " the job. Through two years much science and technology tackles key problem, the clean car that excogitates car of contented country Ⅳ successfully already to discharge uses steam derv level, the clean car that for our country production car of contented country Ⅳ discharges provided main technique safeguard with steam derv.

This duty is decided gave what Ⅳ discharges to accord with a country " motor gasoline " (DB11 ／ 238-2007) and " the car uses diesel oil " (standard of place of DB11 ／ 239-2007) , began to carry out 2008. Of these two standards make, use car of stimulative Beijing area the promotion of oily character not only, the whole that still will drive domestic car to use oily character upgrades.

Current, the technical capability of the benzine that Chinese petrifaction company and Chinese Petroleum Company already had production to satisfy this quality standard and derv, car of public transportation derv has begun Beijing ahead of schedule use the low sulfur diesel oil that satisfies this standard, obtained favorable environmental protection result.

Of motor gasoline and derv standard carry out, the improvement that will be quality of capital air environment and the success of Beijing green Olympic Games was held 2008 offer necessary science and technology to prop up, the improvement that measures empty to our country temperament and environmental protection construction produce positive effect.
