涡轮增压器不能满足柴油机全工况运行的需要，使部分负荷扭矩不足，热负荷增大。

Turbocharger engine can not meet all the needs of the operational state, resulting in the part-load torque inadequate and heat load increases.

输送皂角泵内有设计合理的泄油和回油槽，是齿轮在工作中承受的扭矩力最小，因此轴承负荷小，磨损小，泵效率高。

Pump is the drainage and back into the groove of reasonable design, is a gear in the work under the minimum torque force, so the bearing load is small, wear small, pump with high efficiency.
