|  Centrifugal
force is capable of removing a wide range of particles
extending into the sub-micron range. Analysis of the
dirt collected by a MANN+HUMMEL centrifuge reveals an
ability to remove particles of less than one micron
in size including engine clogging soot: oil films protecting
critical engine components are equally as small. If
not removed contaminant particles in this size range
cause component wear and a consequent reduction of engine
durability.

engine test results to demonstrate
the advantages of a centrifugal by-pass oil

Engine
Test Result 1
2.5 litre direct injection diesel engine with E.G.R.
 The
centrifuge has dramatically reduced the rate of increase
of combustion soot levels within the lubricating oil
to around 50%. Increased soot loading accelerates oil
thickening and contributes to engine component wear.
Controlling the levels extends service intervals and
increases engine durability. |

 Engine
Test Result 2
8 litre diesel engine
As the lube oil becomes loaded with contaminant
the total insolubles level rises and it becomes unserviceable
at a predetermined insolubles level. In the test engine
the maximum total insolubles level was 3%. The test
result shows a by-pass centrifuge controlled total insolubles
at a level below the engine manufacturer's condemnation
limit at more than double the specified oil drain interval. |

 Engine
Test Result 3
8 litre diesel engine
The rate of iron accumulation in the oil
of the engine with a by-pass centrifuge is substantially
lower than an engine operating with just a standard
full flow filter, thus reducing the rate at which engine
components wear out.
