DT100DL – Dispersancy Tester of In-Service Engine Oils

AD systems product

The dispersancy is the property that allows the oil to suspend and carry away “pollutants” of diverse sources such as soot from combustion, metallic particles from wear, corrosion of mechanical parts, and insoluble products resulting from the ageing of the oil, etc.

Beschrijving

The requirement for on-line machinery and oil condition monitoring is becoming evermore apparent as maintenance costs increase and production capacity and equipment performance are maximized. One of the primary functions of a lubricant is to preserve the cleanliness of a combustion engine’s mechanical parts. The cleanliness of the mechanical parts is facilitated by “detergency” and “dispersancy” (DD) additives in the engine oil.

The dispersancy is the property that allows the oil to suspend and carry away “pollutants” of diverse sources such as soot from combustion, metallic particles from wear, corrosion of mechanical parts, and insoluble products resulting from the ageing of the oil, etc.

The DT100DL operates according to ASTM D7899. The instrument simultaneously measures soot and dispersancy. The results reported are combining soot content and dispersancy performance. This test method could be an alternative to very long and expensive test which is the engine test like DV4TD CEC-L-93-04 where the pistons and rings are rated.
