“…The challenges posed to chemical characterization of the PM is best understood after first summarizing the numerous differences of next generation diesels as compared to conventional diesels. Zelenka, Egert, and Cartellieri (2000) discuss the general approach to "clean diesel" technology in terms of three major steps: (a) hardware changes to the engine, (b) incorporation of a DPF, and (c) NO x reduction. To this we can add a fourth component, namely changes to fuel and lubricant composition.…”

The reduction of particulate emissions from diesel engines is of major interest, considering the strict emission standards posed by the legislation worldwide. Although the technology of particulate filters has been under development for more than 20 years, considerable technological challenges remain regarding effectiveness and durability. The emergence of the continuous regenerating trap (CRT) in conjunction with the availability of low-sulfur diesel fuel represents a promising solution, especially for heavy-duty engines. In the present paper, a modeling approach for the combined catalyst and diesel particulate filter system is presented. The model is used to understand the main behavior trends of the oxidation catalyst and the NO 2 regenerated trap individually and as a system. Illustrative model applications are also presented for the case of a modern heavy-duty engine and operating conditions corresponding to the European testing procedures. Although the model is based on global reaction schemes, it is useful in explaining the parameters affecting the CRT system behavior in the real world. Such engineering models are expected to support the selection and design of CRT systems, minimizing the testing effort.

“…1 The particulate filter technology is also considered the most promising solution toward attaining the emission standards of heavy-duty vehicles. [2][3][4][5] Filter regeneration, i.e., the process of soot removal from the filter to avoid excessive backpressure buildup, can be accomplished by thermal soot oxidation by the exhaust gas oxygen. This reaction occurs with noticeable rates at temperatures above 500-550 °C, which are rarely met under typical operating conditions.…”

The diesel particulate filters (DPFs) technology has impressively advanced especially during the last years, driven by the interest in the reduction of automobile particulate emissions. This paper is concerned with the effect of NO 2 as an active oxidation agent in the regeneration process of the soot accumulated in the particulate filter. Experiments at realistic conditions using a diesel engine equipped with a standard oxidation catalyst and a particulate filter are carried out at a wide range of operating conditions. These results are used to validate an already available mathematical model of the NO 2 -assisted regeneration phenomena in the particulate filter. The combined use of experimental and modeling results provides interesting conclusions regarding the significance and the chemistry of the reaction of soot with NO 2 . The advantages and drawbacks of such an approach compared to standard laboratory synthetic gas studies are discussed. The agreement between experimental and simulation results in terms of engineering interest (rate of soot accumulation or depletion) is quite satisfactory and indicates that such a type of model could be a promising design tool.
