摘要
以即将制定的《摩托车和轻便摩托车排气可见污染物限值及测量方法》标准中的限值为依据,用急加速法对我国新生产摩托车和在用摩托车的排烟进行部分抽样检测,结果表明,四冲程摩托车的排烟通过率为100%。对二冲程摩托车而言,采用自带润滑油以及自行润滑模式,无论是新生产摩托车还是在用摩托车其排烟通过率均在10%以下。若采用低烟油且混合比为50∶1时,则通过率可达60%以上。
According to the limits from the standard which will be set - Limits and Measurement Methods for Smoke Emissions from Mopeds and Motorcycles, motorcycle samples were tested in our country, with the method of test for exhaust smoke under snap - acceleration conditions for motorcycles. The results show that all of the four - stroke motorcycles can pass the test. As for two - stroke motorcycles, if the lubricating mode is not changed and oil is not special low smoke two - stroke oil, both the new motorcycles and the used ones, the pass ratio is less than 10%. If low smoke two - stroke oil is introduced, and the fuel - oil ratio is 50：1, more than 60% motorcycles can pass the test.
