Abstract
It is very important for the control of particulate emissions in diesel engines to reduce oil consumption.
In order to control oil consumption in diesel engines, the mechanism by which sliding surface profiles of piston top rings are changed during endurance testing and the effect of the profiles on oil consumption were determined.
The results obtained indicate that oil consumption depends largely upon the ratio of barrel face drop (e) to effective sliding surface width(B) of top ring profiles after endurance testing. The results also indicate that when the e/B is less than 6 /1000, oil consumption increases greatly.
A technique is proposed for reducing oil consumption by controlling the e/B ratio through optimizing the top ring design.
