Effect of different lubricating oil formulas on the adaptability of cGPF aftertreatment

Based on two different components of lubricating oil, this paper analyzes the filtration efficiency, ash accumulation speed, vehicle WLTC emissions, fuel consumption, and CT scan on a National V emission standard engine equipped with a cGPF aftertreatment device. The results show that both oils can ensure that cGPF meets the emission and fuel consumption requirements of National VI emission standard, but oil F accumulates ash quickly before the ash accumulation of 33% in the discharge, which has a significant effect on PN reduction, and oil C accumulates ash faster after the accumulation of 33%. The effect of reducing the PN is accelerated. Oil F is based on a full calcium detergent system, which has a trend of first to slower for the collection efficiency; while oil C is based on a mixed Ca/Mg detergent system, which has a trend of first slowing and then fasting the collection efficiency. The critical point is generally about 33% of accumulated ash. For oil F, less ash is deposited in the front and middle of the cGPF, while more ash tends to deposit towards the outlet. In contrast, cGPF aged with Oil C has a relatively uniform deposition distribution.
Key words: Lubricating oil formula / emission / collection efficiency / accumulated ash / ash distribution
