An oil/solvent mix was prepared by using CAT DEO 15W40 and filtered kerosene in a 50/50 mix. After mixing well, and de-aeration in an ultrasonic bath, the solution was particle counted using a LaserNet Fines C instrument to establish a baseline.
A solution to wash the particles into a clean sample bottle was made from 50/50 15W40 CAT DEO and filtered kerosene. The particles were removed by pushing the particles into a 50-ml graduated cylinder with a Teflon spatula. A glass funnel was used to capture the particles. The walls of the filter canister were washed with the oil/solvent mix, as well as the sides of the funnel. The cylinder was brought up to a final volume of 50-ml that contained the particles and the oil/solvent mix. After mixing and de-aeration, the sample was particle counted on the LaserNet Fines.
After particle counting, it was observed that there was a small amount of large particles that had settled on the bottom of the sample bottle. These particles were likely not counted in the analysis because of their size and rapid settling to the bottom of the container.
8-Cylinder Diesel Engine Captured Particle Analysis
11.3 million particles captured between 4µm and 21µm in one hour.
Fewer Particles in Oil = Higher Reliability + Longer Life
This test determined the absolute number of particles that passed through a new oil filter on a newly remanufactured engine. A FilterMag CT4.9 on each filter was used to capture these particles and hold them against the inside wall of the oil filter. This occurred during the second hour of operation on a dynamometer.
The FilterMag CT4.9s captured over 5.67 million particles between four and 21µm in diameter. This happened in one hour of operation on only one filter. Assuming both filters caught the same levels, the total count conservatively exceeds 11.3 million particles.
Equipment: 8-cylinder diesel engine
Filtration: Two spin-on filters rated at 25µm
FilterMags: CT4.9s snapped onto the outside of each filter
Run Time: One hour after FilterMag installation
Proven in the Field
16-Cylinder Diesel Engine Case Studies
75% average reduction in engine oil contamination
Twenty haul trucks with 16-cylinder diesel engines were engaged in a FilterMag Engine Oil Case Study.
Two FilterMag CT4.9 were installed on each of the engine’s four oil filters on twenty trucks.
Results: 75% reduction in engine oil contamination ≥4µm. Reductions were over and above existing centrifugal oil filtration.
12-Cylinder Diesel Engine Oil Lubrication Case Studies
94% and 49% Reduction in Oil Contamination
Two Blast Hole Drills with 12-cylinder diesel engines were engaged in a FilterMag Engine Oil Case Study.
Two FilterMag CT4.9 were installed on each of the engine’s three oil filters on twenty trucks.
Results: 94% and 49% reduction in engine oil contamination ≥4µm.
8-Cylinder Loader Diesel Engine
$97,500 Expected Savings per Loader
• 70% reduction of particles ≥4 µm results in an expected 60% increase in engine life.
• $97,500 per loader cost savings expected from reduced expenses and extended life.
Tug Boat Diesel Engine
76% Reduction in Oil Contamination with FilterMag
Marine Diesel Engine Test Results
At 513 hours of operation, an oil sample was taken. Then the oil and all six engine oil filters were changed, and two FilterMag CT4.9s were installed on each filter.
The oil and filters were changed 105 hours later, and the filters visually inspected. Testing determined that the ≥4µm particle count was reduced by 76%.
