Abstract
- A DeNO<subscript>x</subscript> demonstration system for a diesel engine used in construction machineries and mobile cranes was setup. In preliminary experiments various extruded and coated SCR catalysts were evaluated with and without oxidizing pre-catalyst. The data from stationary tests with two selected catalysts were used to establish various model-based control algorithms for the optimum dosage of urea in the ESC and ETC. A NO<subscript>x</subscript> conversion of >93% at <10 ppm average ammonia slip could be achieved at a converter-to-swept volume ratio of <2.0. [ABSTRACT FROM AUTHOR]
