市售汽油清净剂清净性能模拟评价分析

Simulated evaluation of cleaning character of gasoline detergents

在汽油清净剂清净性模拟试验机上,采用国家标准GB19592—2004附录B中所规定的汽油机进气阀沉积物模拟试验方法,对常见的市售汽油清净剂进行了清净性模拟试验研究。实验结果表明:市售汽油清净剂质量良莠不齐,已做的100种清净剂中,有效清净剂仅占26%左右。

The gasoline engine intake valve deposit （IVD） experiment was processed on the simulated test apparatus which estimated the cleaning character of gasoline detergent by using the method of GB 19592--2004 appendix B. All the experiment samples of gasoline detergent were sold from the market. The experiment results show that the performance of the samples were very different. Only 26% in the 100samples were effective.
