通过这些改进降低了燃油消耗率，并且能够燃烧高粘度重油，改善了低负荷性能，提高了主要零件的使用寿命。
After improvement, the fuel consumption has been reduced, the performance at low load and the life of main parts have been improved, furthermore, the high viscosity heavy fuel can be used.
由于低负荷操作，可以预先知道引起油头、燃烧室、增压器、透平的脏堵，检查周期须缩短，维修保养周期须更新，汽缸油供给率须调整。
Due to low load operation, the inspection intervals shall be shortened, the maintenance intervals shall be reviewed, and the feed rate of Cyl .
试验结果表明，在各负荷下EGR率最大值为15.4%：燃烧过程缸内压力的最大值和缸内平均温度的最高值均有所降低；
Test results show that, the maximum of EGR rate is 15.4%; Compared with original data, the maximum of in-cylinder pressure and average temperature all drop a little.
