ABCON AS manufactures teflon based lube oil additives for the maritime industry
ABCON MARINE+ products are designed to reduce operating expenses of machinery by decreased wear and tear and reduced friction
In the ideal world lube oil keeps two mechanical parts from contact, but not until the velocity is high enough
Reynold’s Law applies
Conventional lube oil products have their limitsConventional lube oil products have their limits
From Pounder’s Marine Diesel Engines and GasTurbines (page 122): A typical surface finish for the cylinder liner
of a modern engine in service is around 0.5 my, while the oil film thickness of three times this value (1.5 my) - required to prevent asperety contact - may not be established until some distance down the stroke from top dead centre. The conditions for adhesive wear are therefore present at around top dead centre.
Wear metals in used lube oil show the degree of nonperformance
Micro surface picture
Before: roughness depth 0,5 μm
After: ABCON teflon particles fill the grooves -> less metal contact
4,500 tdw supply vessel Auxillary engine Cummins NTA855 G3 Added 3% ABCON-DIESEL ENGINE+ to
crankcase oil
In other words –Due to reduced blowby the oil change intervals were increased from 477 h to 780 h
and still be below TAN 14.7
