对GK1G -C型机车运用过程中出现冒黑烟严重的现象进行了分析。通过计算 ,得出该型机车原配的 2 0GJ 0 0EA型增压器与 12V190BJ6 型柴油机性能不匹配的结论 ,提出重新选配J170型涡轮增压器的解决措施。措施落实后 ,效果显著。
The phenomenon of severe black smoke in GK1G-C locomotives was analyzed. Through the calculation, it is concluded that the performance of 20GJ 0 0EA turbocharger and 12V190BJ6 diesel engine of the original locomotive are not matched, and the resolvent of re-matching J170 turbocharger is proposed. After the implementation of the measures, the effect is remarkable.
