A Diesel Particulate Regeneration System Using a Copper Fuel Additive 930131

An earlier study (SAE Paper 920364) documented the ability of a Copper-based fuel additive to initiate regeneration of a particulate trap without external heat sources.Work performed with Southeastern Pennsylvania Transit Authority on diesel particulate filter systems for a 6V-92TA mechanical engine has been expanded to include 6V-92TA electronic, MAN and Caterpillar engines as well as an increased number of 6V-92TA mechanical engines. Both cordierite wall flow and fibre filter systems are currently being evaluated for performance and durability in field service.This paper outlines performance of the system which uses a copper-based fuel additive to induce regeneration along with emission reductions and health effects data. Additional data on compatibility of the copper fuel additive with typical commercial diesel fuels and lubricants is also presented. Specific details are given on the reliability of the system, mileage accumulated and problems encountered during revenue-service operation.
