An internal combustion engine exhaust modification system for transforming exhaust emissions from an internal combustion engine into modified exhaust emissions. The exhaust modification system includes a housing extending between inlet and outlet ends thereof. The system also includes an impeller rotatably mounted in the housing, and a filter subassembly downstream from the impeller. The filter subassembly removes part of particulate matter and liquid droplets in the exhaust emissions to transform the exhaust emissions into modified exhaust emissions. The system includes a conduit extending between an inner end thereof positioned to direct cooler air exiting therefrom into the housing toward the filter subassembly, and an outer end thereof. The system also includes a funnel subassembly having a funnel body for directing the cooler air into the outer end of the conduit.

An exhaust gas cleaning system includes a particle filter device comprising a casing, plural hollow ceramic filter rods arranged at least partly inside a gas passage of the casing, and a gas inlet and gas outlet. The particle filter device guides exhaust gas from the gas inlet, through the gas passage and to the gas outlet. The particle filter device further comprises a perforated plate extending at least partly along the filter rods and partly blocking an exhaust gas flow path from the gas inlet to the gas passage. The perforated plate defines openings allowing exhaust gas to flow into the gas passage. The filter rods are gas permeable to allow exhaust gas to penetrate, during filtration, a respective wall of the filter rods and flow into the filter rods. A respective open upper end of the filter rods communicates with the gas outlet so exhaust gas leaves the casing.

A pillar shaped honeycomb structure includes: an outer peripheral wall; and porous partition walls disposed on an inner side of the outer peripheral wall, the partition walls defining a plurality of cells, each of the cells extending from one end face to other end face to form a flow path, wherein the cells include a plurality of wire pieces made of a magnetic substance, the wire pieces being provided apart from each other via spaces or buffer materials in an extending direction of the cells.

A diesel-electric locomotive includes a diesel emissions reduction unit, including an inlet configured to receive an exhaust stream of a high-speed diesel engine; means for trapping at least a portion of diesel particulate matter contained in the exhaust stream; an aqueous NH.sub.3 dosing system including a dosing controller in communication with an electronic locomotive controller and a nitrogen oxide (“NO.sub.x”) concentration sensor and an ammonia (“NH.sub.3”) concentration sensor, at least one oxidation catalyst panel arranged to isolate the NO.sub.x concentration sensor from NH.sub.3 in the exhaust stream; mixing elements located between the dosing system and the NO.sub.x and NH.sub.3 concentration sensors to mix metered aqueous NH.sub.3 in the exhaust stream; a selective catalyst reactor bed located between the mixing elements and the NO.sub.x and NH.sub.3 concentration sensors; and an exhaust heating system in communication with at least one of the dosing and electronic locomotive controllers.

A method for manufacturing a honeycomb structure, includes: a step of manufacturing a honeycomb formed body to manufacture a non-fired honeycomb formed body having volume of 7 L or more; a drying step of drying the manufactured non-fired honeycomb formed body to obtain a honeycomb dried body; and a firing step of firing the obtained honeycomb dried body to obtain a honeycomb structure. The drying step includes: an induction drying step to obtain a first dried honeycomb formed body by removing 20 to 80% of the entire water that the non-fired honeycomb formed body contained before drying, and a microwave drying step to obtain a honeycomb dried body by removing the residual water. The honeycomb dried body subjected to this microwave drying step is obtained by removing 90% or more of the entire water that the non-fired honeycomb formed body contained before drying.
