润滑油消耗会对与柴油发电机的发动机排放、性能和维护相关的许多方面产生重大影响。在采用排气后处理的柴油发动机中，润滑油会对后处理系统和部件产生许多负面影响。以下列出了控制润滑油消耗的一些原因。

1、降低柴油发电机维护成本

Reduce maintenance costs
更换柴油发电机的消耗的机油是一项额外的维护项目，会增加发动机的维修成本。在某些情况下，过量的机油消耗会导致机油更换间隔缩短。润滑油消耗也会影响发动机中沉积物的形成速度。

Replacing the oil consumed by the diesel generator is an additional maintenance item that will increase the maintenance cost of the engine. In some cases, excessive oil consumption can result in shortened oil change intervals. Lubricating oilconsumption also affects the rate of deposit formation in the engine.

2、减少排放Emission reduction

润滑油会导致发动机废气排放增加。特别是，润滑油可能是以下物质的重要来源:

Lubricating oil will increase engine exhaust emissions. In particular, lubricants may be an important source of following substances.

1）碳氢化合物和一氧化碳排放，尤其是在小型发动机中。

Hydrocarbon and carbon monoxide emissions, especially in small engines.

2）PM总质量和粒子数排放。

The total mass of PM and particles emitted.

3、降低对后处理系统成本和性能的影响

Reduce the impact on the cost and performance of the post-processing system

润滑油消耗积灰会对柴油微粒过滤器产生重大影响(DPF)。在DPF积累的大部分灰烬是由于发动机消耗的润滑油。保持低润滑油消耗允许:

The ash accumulation of lubricating oil consumption can have a significant impact on the diesel particulate filter (DPF). Most of the ash accumulated in the DPF is due to the lubricating oil consumed by the engine. Keeping lubricating oil consumption low allows.

1）由于较低的积灰率，安装在发动机上的柴油机微粒过滤器较小，

Due to the lower dust accumulation rate, the diesel particulate filter installed on the engine is smaller.

2）较不频繁的再生(和燃料经济性损失)以避免过大的压降，

Less frequent regeneration and fuel economy loss to avoid excessive pressure drop.

3）DPF陶瓷基板的劣化更少。 

DPF ceramic substrates are less degraded.
