  • Patent number: 10464652
    Abstract: An exhaust system for a marine exhaust system includes two riser conduits, each being connected to a Y-pipe at an outlet end. An inner tube of each riser conduit directs exhaust gases through a catalytic converter assembly and into the Y-pipe. An outer tube surrounds each inner tube to define a cooling liquid passage between the inner and outer tubes to direct cooling liquid into one of the inlets of the Y-pipe. A bellows couples one of the riser conduits to one of the inlets of the Y-pipe. Each bellows surrounds one of the inlets of the Y-pipe and one of the riser conduits. To minimize reversion, the inner tube of each of the riser conduits extends into one of the bellows further than the outer tube of the respective riser conduit.

    Abstract: The present invention provides an automotive exhaust system that removes harmful contaminants from engine exhaust and thus reduces air pollution, presents a number of distinct and significant benefits and advantages. Foremost, the Green Muffler subjects engine exhaust gases to a two-stage cleansing and purification process, first scrubbing the gases in a recirculating air-and-water bath; and then combining the remnant gases with an air-freshening chemical before release to the atmosphere. The Green Muffler, then, serves to lower a vehicle's carbon-dioxide and carbon-monoxide emissions and thereby reduces the level of air pollution and atmospheric warming due to car exhaust. Further, the Green Muffler reduces the temperature of vehicle exhaust, another plus for the planet.

  • Publication number: 20100186387
    Abstract: A method of affecting soot particulate size in an internal combustion engine exhaust by selectively providing a phosphorous based additive to the engine during combustion. Soot particulate size can be increased or decreased depending on the particular additive provided. Also disclosed in a conditioning effect experienced by using a phosphorous based additive for a period of time. A conditioned engine can also have its exhaust properties affected during the life of its conditioned state. Manipulating particle size during engine operation can employ an oligomeric phosphorous compound. Engine conditioning can employ a monomeric phosphorous containing compound, an oligomeric phosphorous containing compound, a polymeric phosphorous containing compound, or combinations thereof.

  • Publication number: 20100101222
    Abstract: The present invention relates to a device for introducing a liquid into a gas flow, more preferably for an exhaust system of an internal combustion engine. The device includes a chamber, an injection device and a channel. The channel with a circumferential region of an inlet section protrudes into the chamber and there on an inner side facing the gas flow has a surface. Said surface is arranged offset to the inside with respect to a channel profile. The proposed design results in improved evaporation of the liquid introduced into the gas flow.

  • Publication number: 20100071351
    Abstract: An exhaust emission control system, which comprises control means 8 operable, in response to satisfaction of a given stop condition, to automatically stop an engine, and subsequently, in response to satisfaction of a given restart condition, to automatically restart the automatically stopped engine, a flow passage 6 adapted for an aqueous urea solution for reducing nitrogen oxides contained in exhaust gas of the engine, and supply/recovery means 7 adapted to drive a pump 10 to supply an aqueous urea solution to the flow passage and recover an aqueous urea solution from the flow passage. The control means is operable, when the engine is forcibly stopped by turning off an ignition switch, to instruct the supply/recovery means 7 to recover an aqueous urea solution from the flow passage 6, and, when automatically stopping the engine in response to satisfaction of the given stop condition, to prohibit the supply/recovery means 7 from recovering an aqueous urea solution from the flow passage 6.

  • Publication number: 20100058748
    Abstract: A method to dislodge an adherent residue in an EGR cooler, the EGR cooler installed in an engine. The method comprises flowing an exhaust gas through an adherent-residue bearing surface of the EGR cooler when a temperature of the adherent-residue bearing surface is below a dewpoint temperature of the exhaust gas, enabling water vapor from the exhaust gas to condense on the adherent-residue bearing surface, heating the adherent-residue bearing surface to above the dewpoint temperature of the exhaust gas, and enabling condensed water on the adherent-residue bearing surface to evaporate. Other embodiments provide a method to recirculate an exhaust gas from an exhaust port of an engine to an intake of the engine via an EGR cooler, and a related EGR system.
