Technology assessment of bypass oil filters

The problem of waste disposal is taking on increasingly urgent proportions in our supply-oriented economy.

As disposal without environmental pollution is not usually possible, the trend today is towards the avoidance of waste in the first place. Ultrafine bypass filters can reduce the amount of waste oil requiring disposal. The use of ultrafine oil filters is the subject of considerable controversy, however, with the oil and automobile industries in particular putting up strong objections.

The study documented the technical discussion on the basis of an extensive literature analysis. Operating experiences were analysed by way of a written questionnaire sent to all users of ultrafine bypass filters. It showed that the average oil-change interval increased almost sixfold, with a corresponding reduction in the amount of old oil needing disposal. The literature analysis also showed that wear processes could be considerably reduced and fuel consumption cut marginally as well. However, the effectiveness of the ultrafine filtering process depends to a large extent on the quality of the filters used, the type of vehicle and the operating conditions. For this reason, tests should be carried out on entire fleets so as to enable the technical background to be studied in detail under practical conditions.
