Preliminary Experiment
The preliminary experiments consist of finding properties of materials that are helpful to the operation of the main experiment. These properties are: the specific heat capacity of diesel soot (specifically the kind of soot expected from Cummins engines); and the specific heat capacity of the Diesel Particulate Filter that Cummins utilizes. The diesel soot specific heat capacity may be listed in various scientific journals or Society of Automotive Engineers (SAE) reports. The other more company specific property values can be found through simple experiments involving measuring the temperature response of the substance in the presence of an energy (heat) stream. Once these values are obtained, it will be possible to proceed with the main experimental research. Main Experiment
A decent deal of extensive experimental research needs to be performed in order to change this suggestion from a theory to a concrete solution. The experimental test setup should include a filter (in can) hooked up to a controlled simulated exhaust system. Temperature measurement devices should be placed directly upstream and downstream of the filter in the exhaust system. Temperature measurement devices should also be placed on the interior as well as the exterior of the filter. The temperature measurement devices should be placed in a grid setup around and inside the filter so as to attain longitudinal and latitudinal temperature measurements. This should account for geometry based heating of the filter. Following is a sample diagram of a simplified filter (no channels) with a possible grid setup for temperature measurement device locations. The web circular grid on the front surface of the cylinder should be duplicated more than once moving lengthwise down the filter.
