Having Exhaust Gas Collection And Storage, Or Use As A Pressure Fluid Source Patents (Class 60/281)
  • Patent number: 11874152
    Abstract: A technique facilitates fluid flow measurement by providing a meter able to accurately monitor fluid flow of a liquid even if gas is present in the liquid. The meter may comprise a tubing with an internal flow passage and a wedge or other restriction extending into the internal flow passage. A first port is located upstream of the restriction and a second port is located downstream of the restriction to enable monitoring of a differential pressure across the restriction. The differential pressure can be used to determine the desired flow parameter, e.g. volumetric flow. The system facilitates separation of gas from the liquid and utilizes a gas bypass. The gas bypass routes the separated gas past the restriction, e.g. wedge, before directing the gas back into the fluid flow path.

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.

  • Patent number: 8360035
    Abstract: During starting of an engine that has a circulation path through which argon, used as working gas, is circulated back to a combustion chamber and that uses hydrogen as fuel during operation, oxygen is supplied in such a manner that the oxygen supply ratio is higher than that used during normal operation. Thus, the entirety of hydrogen supplied into the combustion chamber reacts with oxygen and is burned. When the engine is being started, because gas is not turbulent enough, hydrogen and oxygen are likely to be mixed poorly. Therefore, when oxygen is supplied in such a manner that the ratio of oxygen supply amount to the hydrogen supply amount is higher than the theoretical ratio, even if oxygen and hydrogen are not mixed so well, the chance that hydrogen contacts oxygen is increased. As a result, combustion takes place in a more appropriate manner, which improves the engine startability.

  • Publication number: 20120210696
    Abstract: Following a cold start of a hydrocarbon-fueled engine operated in a lean-burn-combustion mode, several seconds and minutes may be required for the exhaust gas stream to heat exhaust treatment devices in the exhaust system and conduit to their effective operating temperatures. The warm-up period may be particularly long for a NOx reduction catalyst (SCR) located downstream in the exhaust flow system. Accordingly, a bed of absorbent material, such as a suitably sized bed of alumina particles, located upstream of the SCR, is used to temporarily absorb water and NOx from a relatively cold exhaust until the exhaust has suitably heated the SCR to its operating temperature. Then, the warmed exhaust will remove the water and NOx from their temporary storage material and carry them to the reduction catalyst.

  • Publication number: 20110237392
    Abstract: A pressure accumulation system for an internal combustion engine can prevent exhaust pressure from excessively increasing when pressurized gas is contained in a pressure accumulation container. A pressure accumulation system is applied for an internal combustion engine provided with an exhaust shut-off valve mounted in an exhaust path. The pressure accumulation system has a pressure accumulation tank into which gas can be introduced from that portion of an exhaust path. The pressure accumulation system also has a sensor for detecting the exhaust pressure, and an EGR valve is controlled based on the detection value from the exhaust gas sensor such that the pressure in that portion of the exhaust path which is on the upstream of the exhaust shut-off valve is limited below a predetermined exhaust gas upper limit value (Pmax) when gas is contained in the pressure accumulation tank.

  • Patent number: 8020373
    Abstract: A method and a system for regenerating an exhaust gas treatment device for an internal combustion engine having at least one cylinder are presented. The system comprises an exhaust gas treatment device, a fuel storage means, a fuel vapor retainer, and an engine control unit adapted to selectively allow fuel vapors from the fuel vapor retainer to reach the engine. The method comprises regenerating an exhaust gas treatment by allowing fuel vapors from the fuel vapor retainer into at least one of the engine cylinders, and inhibiting combustion in at least one of the cylinders into which fuel vapors are to allowed.

  • Patent number: 7992382
    Abstract: A particulate trap system for an internal combustion engine includes a plurality of contiguous porous walls, and a remotely actuated relief valve downstream of said trap for periodically creating a reverse pressure throughout the exhaust system upstream of the relief valve and including said trap. A reversing apparatus periodically creates a reverse pressure drop across a portion of the contiguous porous walls of said trap to dislodge accumulated particulate and cause a portion of the filtered exhaust gas to flow back through said portion of the contiguous porous walls to remove particulate therefrom. A control system actuates the relief valve and the reversing apparatus. In one embodiment the system is utilized on a vehicle and the reversing apparatus includes a relief valve that is also operative as an exhaust brake.

  • Patent number: 7964148
    Abstract: A method and system of providing compressed substantially oxygen-free exhaust gas for industrial purposes including the steps of extracting exhaust gas from a lean burn engine consuming a mixture of natural gas fuel and air, passing the extracted exhaust gas through a cooling step to cause entrained water vapor therein to condense out, separating and disposing of the condensed water, measuring the oxygen content of the exhaust gas, using the measurement to regulate the quantity of natural gas fed into an igniter into which the exhaust gas is also fed so that substantially all of the oxygen in the exhaust gas is consumed by combustion with the natural gas in the igniter to provide at an outlet of the igniter substantially oxygen-free exhaust gas, and compressing the substantially oxygen-free exhaust gas to provide compressed exhaust gas for industrial applications.

  • Publication number: 20100268443
    Abstract: A method for providing fuel to internal combustion engines including fuel activation prior to injection, comprising: 1) dissolving a mixture of gasses providing improved fuel dispersing after fuel injection into a combustion chamber; 2) stimulating dissolved gasses desorption from a unsaturated fuel solution; 3) full control of fuel flows with dissolved gas/gasses to and from injectors. FET technology is based on Henry law (dissolving gasses in the liquids) and Kelvin principle (vapor pressure over droplet surface). A new system for proving fuel to internal combustion engines consists of compact components, allows excluding a complex exhaust gasses recirculation system, can be easily added to existing diesel and gasoline engine fuel supply systems. The method and system were tested with 4 different types of engines.

    Abstract: A second air flow control apparatus disposed between an air inlet port of an engine and an exhaust port includes a body, a base, a moving member, and a gas thread. The body has a cavity, an air inlet and an air outlet, the air inlet and the air outlet being connected through the cavity. The base is fixed in the cavity, having at least an opening for controlling the air flow through the air flowing path. The moving member is pivotably disposed in the cavity or the base by a spring force and having at least a gate and a cover configured for controlling the area of the opening. The gas thread is connected to the moving member and configured for pulling the moving member to generate a processional rotation and a resetting rotation. The rotations are configured for controlling the gate and the cover part to adjust the opening area of the opening so as to precisely control the second air flow.
