Abstract
Experiments are carried out with the diesel particulate filter and oxidation catalyst embedded in the active-flow configurations on a single cylinder diesel engine. The combined use of various active flow control schemes are identified to be capable of shifting the exhaust gas temperature, flow rate, and oxygen concentration to favorable windows for filtration, conversion, and regeneration processes. Empirical and theoretical investigations are performed with a transient one-dimensional single channel aftertreatment model developed in FORTRAN and MATLAB. The influence of the supplemental energy distribution along the length of aftertreatment device is evaluated. The theoretical analysis indicates that the active-flow control schemes have fundamental advantages in optimizing the converter thermal management including reduction in supplemental heating, increase in thermal recuperation, and improving overheating protection. This concept is further investigated by developing an energy efficiency analysis that highlights the influences of gas flow, heat transfer, chemical reaction, and substrate properties on the aftertreatment performance.
