US Army Workshop on Engine Lubrication (3th), 13-14 April 1988
Abstract
The general introduction to the session had been written in advance by Professor Dowson. When giving his verbal presentation he placed particular emphasis on three areas. He felt that early studies had given too much attention to the main bearings, to the almost complete exclusion of the piston rings and valve train assembly. Recent studies had shown that over half the friction losses came from these and that they deserved a proportional amount of effort. It was possible to both measure and calculate the oil film thicknesses in these components. It should thus be possible to model their working in future engine designs. Secondly he said that he wished to emphasize the importance of parametric investigations and gave some examples. It was more important to know the way in which the friction or oil film thickness changed rather than trying to calculate the absolute values. Finally he put in a plea for more information to be got out of routine engine tests. He cited the example of piston ring profiles being taken before and after testing as an example of the type of things he had in mind.
