Abstract
Engine tests were conducted to determine the effects of various full flow and by-pass lube oil filter combinations on diesel engine wear. The filter performance was determined by measuring the wear of piston rings, main and rod bearings in a Cummins NTC-335, after contaminating the lube system with a known amount of AC Fine Dust to accelerate wear.
The results of these tests prove:
-
1.
It is possible to dramatically reduce the size of the by-pass filter through the use of stacked discs filter technology.
-
2.
No sacrifice of engine protection or filter life is necessary.
-
3.
By-pass filters extend engine life through improved filtration and reduced wear providing the lowest total cost to the engine user.
