The Influence of an Oil Recycler on Lubrication Oil Quality with Oil Age for a Bus Using in Service Testing

摘要

A method of cleaning lubrication oil on the was investigated using a fine bypass particulate filter followed by an infra red heater, to remove water and light diesel fractions in the oil. Two bypass filter sizes of a 6 and 1 micron were investigated, both filter sizes were effective but the one micron filter had the greatest benefit. This was tested on two nominally identical Euro 2 emissions compliance single decker buses, fitted with Cummins 6 cylinder 8.3 litre turbocharged intercooled engines. Thee vehicles had oil deterioration and emissions Characteristics that were significantly different, in spite of Their similar age and total mileage.
