Lubricating oil consumption can have a significant impact on many aspects related to engine emissions, performance and maintenance of diesel generators. In diesel engines that adopt exhaust gas aftertreatment, lubricating oil will have many negative effects on the aftertreatment system and components. The following is a list of some reasons for controlling lubricating oil consumption.
1. Reduce maintenance costs
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. Emission reduction
Lubricating oil will increase engine exhaust emissions. In particular, lubricants may be an important source of following substances.
1) Hydrocarbon and carbon monoxide emissions, especially in small engines.
2) The total mass of PM and particles emitted.
3. Reduce the impact on the cost and performance of the post-processing system
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) Due to the lower dust 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) DPF ceramic substrates are less degraded.
