An Experimental Evaluation to Determine the Effect of an Organometallic Fuel Additive on Particulate Trap Regeneration 900920

The regenerative characteristics of a diesel particulate filter have been experimentally examined. The effect of particulate accumulation on system backpressure was of primary interest. To improve particulate regeneration, a copper compound was added to the fuel. The test results demonstrate that copper-containing fuel additives improve the regeneration characteristics of the filter, maintaining system backpressure at an acceptable level. Improved regeneration performance is expected to extend the operating range and life of the filter system. A model describing regeneration characteristics was developed to indicate the benefits of fuel copper concentration in controlling system backpressure.
