Lubricating oil consumption will have a significant impact on many aspects related to engine emissions, performance, and maintenance of diesel generators. In diesel engines that use exhaust post-treatment, lubricating oil can have many negative effects on the post-treatment system and components. Here are some reasons for controlling lubricant consumption:

1. Reduce maintenance costs of diesel generators

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 lead to shortened oil change intervals, and lubricating oil consumption can also affect the rate of sediment formation in the engine.

2. Reduce emissions

Lubricating oil can cause an increase in engine exhaust emissions. Especially lubricating oil may be an important source of the following substances:

1) Emissions of hydrocarbons and carbon monoxide, especially in small engines.

2) PM total mass and particle number emissions.

3. Reduce the impact on the cost and performance of post-processing systems

The consumption of lubricating oil and the accumulation of dust can have a significant impact on diesel particulate filters (DPF). Most of the accumulated ash in DPF is due to the lubricating oil consumed by the engine, and maintaining low lubricating oil consumption allows for:

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

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

3) The degradation of DPF ceramic substrates is less.
