Authors Abstract
Content
The motor-driven centrifuge has been applied for many years on high horsepower, low-speed marine diesels to provide clean, debris-free fuel and to control wear and combustion contaminants in the engine lubricating system. More recent versions, using the pressure of the lube circuit to self-power a high-speed centrifuge turbine, have been widely applied to diesels in heavy-duty trucks, transit buses, electrical gen sets and to construction and mining equipment in North America and Europe.
In order to to explore the function and performance of the pressure-powered oil cleaning centrifuge in actual field installations, three methods of qualitative and quantitative assessment of diesel lube oil contaminants were applied and are reported in this paper:
  1. 1
    Physical chemistry of the solids collected in the centrifuge bowl to objectively identify the various debris constituents in the used diesel lube oil not removed by standard full-flow lube oil filtration.
  2. 2
    Particle counts of the centrifuged solids using specialized electrostatic methods, providing distribution of all contaminants by size.
  3. 3
    Particle counts of used lube oil on centrifuged-equipped diesels by means of the sample re-suspension method.
