Four kinds of lubricants with special characteristic parameters were tested on a four-cylinder turbocharged diesel engine.By using DMS500 fast response particle analyzer, experiments were carried out to study the influence of base oil types and ash content of lubricants on number and mass concentration of particle emissions, especially the improvement of particle emission with low-ash PAO lubricants. The results of study show that: engine particle emissions using conventional Class Ⅳ PAO lubricants are lower than using conventional Class Ⅱ CI-4 lubricants, especially under middle and high loads. The low-ash lubricating oil of the above mentioned two types can reduce the total amount of diesel particulate emissions. Compared with other three lubricants, the low-ash PAO lubricant has lower total particle number concentration. The effect of reducing particle mass concentration with low-ash PAO under low load is obvious, and it is slightly higher than that of conventional PAO lubricant under high load. Research suggests that low-ash PAO lubricant has excellent performance in improving overall particulate emissions of diesel engine.
