Abstract
THE principal engine modifications needed to prevent and remove the crankcase oil diluents responsible for the deposition and wear experienced in light-duty operation are reported to be:
-
1.
Maintenance of sufficiently high cylinder-wall temperatures.
-
2.
More adequate control of oil sump temperatures.
-
3.
Satisfactory piston-ring blowby control.
-
4.
More efficient oil filtration systems.
Modifications to normal commercial gasolines are said to have relatively little effect in reducing such deposition and wear.
As far as motor oils are concerned, the authors feel that future work should be along the lines of increasing still further the capacity of the oil both for holding in suspension the insoluble products derived from the fuel as well as for neutralizing the acidic materials formed from the products of combustion.
