An exhaust system includes an electrically conductive shell defining an exhaust pathway. The shell includes a tapered portion that tapers inward toward a longitudinal axis of the shell to define a narrowing region of the exhaust pathway. The exhaust system further includes an ionization assembly and an electrical subsystem that applies an electrical potential difference between the shell and at least a portion of the ionization assembly located within the exhaust pathway. The ionization assembly includes a support arm located within the exhaust pathway that extends into the narrowing region of the exhaust pathway. The ionization assembly further includes a plurality of electrically conductive discs mounted on and supported by the support arm. The ionization assembly is electrically insulated from the shell by an electrically insulating support structure.

Methods and systems are provided for a soot sensor. In one example, a method diverting exhaust gas from a main exhaust passage to a second exhaust passage comprising a soot sensor with a rotatable component configurable to capture soot.

A Diesel Particulate Filter (DPF) assembly configured to be incorporated in the exhaust gas stream, the DPF assembly comprising: Quartz/Composite ceramic mixture disposed as filter elements, mechanical support components and optional electrical soot removal solutions including electrical, di-electrical and microwave solutions.

The present utility model belongs to the field of accessories and equipment destined to the automotive market and/or other equipment that require combustive engines, and more particularly it refers to a metallic device that conducts the whirling air to a vortex, Fibonacci's physical law, in addition to regulating the molecules energetically, resulting in higher pressure and lower flow of air intake into the engine, the present solution is extremely important for the engine market, because with this solution, it is possible to improve the fuel burning, reduce the pollutant gases eliminated through the vehicle/machine exhaust pipe, reduce the consumption of fuel, increase the service life of the engine (cooling), regulate the air molecules, increase the engine power by the positive air and make a fixed barrier of the air reducing reflux.

A pollutant filtering assembly for filtering pollutants from vehicle exhaust includes a tube that has a diameter which is sufficient to facilitate the tube to be inserted into an exhaust pipe of a vehicle. A sleeve extends around the tube to facilitate the exhaust pipe to extend between the tube and the sleeve. A handle is pivotally coupled to the tube for inserting the tube into the exhaust pipe. A filtering cartridge is insertable into the tube. The filtering cartridge has a plurality of filtering elements that is each comprised of a unique pollutant filtering material with respect to each other. Moreover, each of the filtering elements can filter pollutants from exhaust of the vehicle.

An internal combustion engine exhaust modification system for transforming exhaust emissions from an internal combustion engine into modified exhaust emissions. The exhaust modification system include a housing extending between inlet and outlet ends thereof. The housing has a first cross-sectional area at a first location that is downstream from the inlet end and a second cross-sectional area at a second location that is downstream from the first location. The second cross-sectional area is larger than the first cross-sectional area. The system also includes an impeller rotatably mounted in the housing, and a filter subassembly. The filter subassembly removes part of particulate matter and liquid droplets in the exhaust emissions to transform the exhaust emissions into modified exhaust emissions.

An exhaust tailpipe/emissions filter employs a reusable/replaceable insert and is configured to slide into and/or onto the exhaust tailpipe of the automobile to reduce air pollution.
