Abstract: A vehicle system (100) includes a conversion catalyst (116), a temperature sensor (156), an indication device (142), and an exhaust gas aftertreatment system controller (132). The conversion catalyst (116) is configured to receive exhaust gas. The temperature sensor (156) is configured to sense a conversion catalyst temperature of the conversion catalyst (116). The indication device (142) is operable between a static state and an impure fuel alarm state. The exhaust gas aftertreatment system controller (132) is configured to receive the conversion catalyst temperature from the temperature sensor (156). The exhaust gas aftertreatment system controller (132) is also configured to compare the conversion catalyst temperature to a conversion catalyst temperature lower threshold. The exhaust gas aftertreatment system controller (132) is also configured to compare the conversion catalyst temperature to a conversion catalyst temperature upper threshold.

Abstract: A simplified method of manufacturing a catalyst for soot combustion includes the synthesis of a catalyst composition. A substrate is prepared for receipt of the composition and a sol solution is created utilizing the composition synthesized. Finally, a catalytic coating is applied to the substrate, through use of the sol solution. The catalyst composition may be any suitable composition including a K2O, CaO, SiO2 (KCS-1) silcate catalyst, and the substrate may be a wire mesh, such as for example, a commercial metallic wire mesh. The application of the coating to the substrate, may be performed through any suitable coating process including, for example, a sol-gel dipping process, spraying, painting, etc.
