Concept
The idea behind this design is to use the exhaust flow rate to our advantage. For example at different engine rpm’s the exhaust flow rate will change. The goal is to calculate the amount of force the exhaust exerts at different engine speeds. The actual mechanism that goes onto the exhaust pipe is a simple filter with an attachment that bolts to it then slides into the exhaust pipe allowing it to slide in one direction at least a half-inch. Allowing the filter and attachment to slide allows the exhaust to push the filter, where on the other side is a device that will measure the amount of force exerted by the flow rate. Now when the filter starts to become clogged with soot the exhaust gases will create more of a force on the filter when trying to pass through it causing the filter slide more against the measuring device. The goal is to find a relation between the forces that the exhaust exerts without a filter and then with a filter and find a relation to how much soot is in the filter.
Specifications · 9 in by 13 in cylindrical filter · Aluminum flat plate that bolts to bottom of filter · Pressure sensitive measuring device that attaches to top of filter · Hollow cylinder that slides into specified exhaust pipe diameter and attaches to aluminum flat plate.
