Factors · COST: This system should have a very low cost. The thermocouple system should have a relatively small cost depending on how exact they need to be. The most expense should come from the monitoring system which is easily available. · TIME OF PRODUCTION: It should not take long to construct this system or add it into the filter construction process. Once optimal placement locations on the filter are found, the process should be almost complete. The machinery is very simple. · COMPLEXITY OF IDEA: This is a VERY simple idea. It is just a comparison of temperature and changes in properties of a system. It is a simple thermodynamics problem. The only complexities arise from analyzing the properties of soot and cordierite. · MASS PRODUCTION CAPABILITY: This system is incredibly easy to produce on a mass scale. Thermocouples and thermocouple monitoring systems are easy to acquire. They should also be easy to integrate into the filter construction process. · SPECIFIC FACTORS: I’m not sure if this idea will work. The specific heat change of the filter due to soot build-up could be immeasurable. Also, it will be difficult to differentiate heat input from the exhaust gases from heat input from other sources.
