Concept Generation

           This change will result in a variance of current. If the current is know that properly coincides with the filter being empty as well as full of particulates, it can then be directly determined how much sot has accumulated in the filter.

           A small voltage source will need to be installed directly where the soot is to be colleted. Several outputs of electrical wiring can run from strategically placed areas within the filter.  These will travel directly into an ammeter that will directly measure the current of the “electrical system” that has been created.

Specifications

· Able to accommodate a 9 inch by 13 inch filter

· Ammeter must reside far enough away from the system as to not cause measurement error due to high temperatures.

· Voltage must be applied directly to cordierite filter

Factors

· COST: The tools needed to construct system, including  the wiring, are relatively inexpensive

· TIME OF PRODUCTION: The time it will take to manufacture one product would be about two days.

· COMPLEXITY OF IDEA: The design itself is uncomplicated

· MASS PRODUCTION CAPABILITY: The ease of mass production is directly related to the complexity of design. Manufacturing could be integrated into standard auto assembly.

· SPECIFIC FACTORS:  Heat sensitive system, Vibration sensitive system
