最近,北京宣布对汽柴油标号进行调整,将目前标号90号、93号、97号的汽油将修改为89号、92号、95号,此次调整对车主有何影响?这主要是从环保角度考虑,降低车用汽油的硫含量标准,由1000克汽油中含硫量为50毫克降低为10毫克。这样汽油中硫含量比原标准减少5倍,意味着排放的硫化物含量浓度降低5倍,PM2.5浓度也随之变低。 Recently, Beijing announced that it will make adjustments to its gasoline and diesel oil labels. At present, the numbers 90, 93 and 97 of gasoline will be revised to No. 89, No. 92 and No. 95. What is the impact of this adjustment on the owners? This is mainly from environmental protection From the perspective of reducing the sulfur content of motor gasoline, the amount of sulfur in 1000 g of gasoline is reduced from 50 mg to 10 mg. This sulfur content in gasoline than the original standard to reduce 5 times, which means that the concentration of sulfide emissions reduced 5 times, PM2.5 concentration also will be lower.
