Insolubles are a build up of combustion related debris and oxidation products. High insolubles will cause lacquer formation on hot surfaces, sticking of piston rings and wear of the cylinder liner and bearing surfaces. The detergent property of the oil will decrease, speeding further deterioration.
Contamination comes mainly from combustion products, fuel ash, carbon and partially oxidised fuel plus a small contribution of oil oxidation products and spent lubricant additive. The major contributor is soot from combustion and this is measured in the insolubles test.
Insolubles constituents include carbon from incomplete combustion of fuel and, to a lesser extent, lubricants, organic polymers from oxidisation of the lube oil and fuel. They also contain sulphates from combustion of fuel sulphur and reaction with TBN additives and wear metals. Metallic fuel ash and airborne grit can also be present, as well as asphaltenes (mainly from engines using residual fuel oil).
Increased oil viscosity will cause:
Insolubles Electronic Cell FG-K25194-KW
The Insolubles Cell works in conjunction with a highly accurate electronic console, which is available with optional software that allows the data to be downloaded from the console to a PC in comma delimited text format. This means that the data stream is separated by commas and is in a standard ASCII format that is readable by standard spreadsheet and data base applications, such as Microsoft Excel and Access.
The Insolubles Test is available as a stand-alone kit, or as part of a comprehensive suite of electronic equipment including cells to test for TBN, Water in Oil and Insolubles.
