Concept The concept of this idea also comes from thermal fluids. Each material has a specific heat that tells how much it will heat up based on how much energy is put into it. The more material there is, the harder an object is to heat up. This concept focuses on the fact that there should be a change in the specific heat of the filter system once it begins collecting soot. The more soot on the filter, the harder it should be to heat. The concept of this idea is to measure the initial specific heat of an empty filter system as well as the specific heat of a “full” filter system. The filter collecting soot should be somewhere between this range. By monitoring the heat of the exhaust gas entering the filter system (energy added to system) and then measuring the temperature response of the filter system, we should be able to locate the position of the filter between the ranges previously mentioned. This should be a direct correlation to the amount of mass in the filter.
Specifications · This concept is mostly research to find properties of the soot accumulating on the filter and the properties of the cordierite filter to determine how the temperature will alter. · Temperature Measuring System · A temperature probe (most likely a sturdy thermocouple system) will be placed in the exhaust system before the filter to measure the amount of heat entering the filter. · A temperature probe system will be placed throughout the filter to monitor how the filter responds to the heat being placed into the filter by the exhaust gas.
