New Filtration Systems for the Control of Exhaust Emissions from Light-Duty Diesel Engines 920365

The paper includes the design, installation and testing of two different diesel particulate filter systems for light-duty diesel engines. The systems were installed on mining vehicles at Kidd Creek Mine in Timmins, Ontario, Canada.The first system utilizes a newly developed pleated-media filtration element. The filter must be cleaned off-board or replaced with a new unit after a duty cycle.The second system applies a ceramic wall-flow monolith. The filter is catalyzed and self-regenerates during high temperature operation periods.Each system includes a diesel catalytic converter which diminishes both the gaseous emissions and the odour of diesel exhaust.Advantages and limitations of the applied technologies are compared in the paper. The results of the performance tests, both bench and harsh underground operations, are discussed.
