· Controlling the dilution ratio · Controlling the dilution solution temperature Mass Measurement System: Includes a calculation computer and a pressure monitor behind the filter · Must be capable of comparing the pressure of exhaust gas entering the filter (from dilution probe) to the pressure of exhaust gas exiting the filter · These inputs go into the system and are compared to a clean filter to determine how much soot is in the filter.
Factors · COST: The cost of this system may be relatively high due to the moderately complicated nature of the dilution system. The dilution probes must monitor a lot of factors and adjust its operation automatically · Time of Production: The time of production for this concept is primarily in the development stage. Once the concept is secured and perfected the production should not take long with dedicated machinery. It will be even quicker with the purchase of previously constructed dilution probes. · Complexity of Idea: The complicated nature of this idea falls primarily into the dilution. It will take a small amount of experimenting to determine the correct formula to input into the computer system so the dilution ratio adjusts to engine conditions correctly. · Mass Production Capability: Once the design is specified and perfected this machinery should be easily duplicated on a mass level. The computer system for this structure should be adaptable to any exhaust system it is placed on and not require any personalization. · Specific Factors: Currently there is little technology available for controlled dilution. The probes must be fabricated almost from the ground up.
