Abstract
This paper discusses the role that lubricant volatility plays in the generation of particulate and other regulated emissions from diesel engines and presents a new technique for continuously controlling oil volatility and thereby reducing visible smoke, particulates, carbon monoxide, and hydrocarbons.
Test results are presented that indicate that a major reduction in particulate emissions can be attained through the elimination, by continuous evaporation, of light lubricating oil fractions. The effects of treatment temperature on regulated emissions are detailed through a series of single cylinder engine tests.
The results of in-service vehicle trials are presented and indicate 40-50% reductions in visible smoke in snap idle tests and reductions in regulated emissions on a number of other test cycles. Monitoring of oil characteristics in the long-term trial indicates that critical oil characteristics are maintained for longer periods than that of control vehicles' oil.
