Claims24
A Diesel Particulate Filter (DPF) assembly configured to be incorporated into the exhaust gas stream of a diesel engine, said DPF assembly comprising:
- one or more pneumatically porous ceramic filter panels;
- support mechanical components attached to said one or more panels so as to form a filter core;
- and
- a DPF assembly comprised of one or more housing mechanical components that create one or more upstream cavities and a downstream cavity pneumatically connected by said one or more porous ceramic filter panels.
A method for creating filter panels for a Diesel Particulate Filter (DPF) assembly, said method comprising:
- crushing mineral fibers;
- creating a composite powder comprised of Silicon Oxide (SiO2), Aluminum Oxide (Al2O3), Diboron Trioxide (B2O3) and Sodium Super Oxide (NaO2);
- creating a filter mix by mixing said mineral fibers with a said composite powder;
- placing said mixture in a mold and sintering said mixture for at least 30 minutes at a temperature of at least 1200° C.;
- gradually lowering the mixture temperature to 700° C. during at least 10 minutes;
- and
- allowing the molded product to cool to ambient temperature.
