Definitions

  • the present invention relates to an insertable device for creating a vortex in a vehicle inlet or exhaust pipe, in order to enhance vehicle performance, e.g., to boost power and save fuel.
  • a number of insertable devices are known that are used to provide mixing to liquid and/or gases including, inter alia, US 830 268, which is designed to improve the circulation in heating systems, US 1 345 791, US 1 584 046, and US 1 868 902.
  • US 830 268 which is designed to improve the circulation in heating systems
  • US 1 115 699, US 1 182 954 and US 1 396 054 that teaches that the mixing device can be formed from a single strip of cut and formed metal.
  • the devices include flanges or are made from materials that have proven inferior when applied to internal combustion engines.
  • Present-day large vehicles, like tractors, diesel trucks and diesel locomotive consume large amounts of fuel. Any savings in fuel will add up to a large amount of savings in operating cost over the lifetime of the vehicle.
  • the inventor of the present invention has found that by designing the fuel saver device to ensure that the gas rotates through the intake or exhaust, the flow enters intake efficiently.
  • the invention is directed to an insertable device in which a strip of stainless steel is cut and bent into a cylindrical shape that is capable of being inserted into a vehicle inlet or exhaust pipe and that improves the vehicle performance during normal operation of the vehicle.
  • the types of vehicles which can benefit by this device include large tractors, diesel locomotives, outboard boat motors and lawnmowers, including both turbo-boosted and carburetted vehicles.
  • Still another object of the invention is to provide a method of using the above device.
  • Fig. 1 shows a fuel saver 10 according to the present invention showing its cylindrical shape.
  • the structure is made from a single strip of Grade 304 or 316 stainless steel with a thickness of 25 mil for large trucks or 10 mil for other automotive vehicles.
  • Tabs 18 extend from the remaining skirt 16 of the cylindrical structure 10. Each tab 18 is bent diagonally along folds 12 to produce dog-ears 14 that are oriented in an upward direction from the page.
  • the starting strip of stainless steel preferably Grade 304 or 316, and preferably 10 mil or 25 mil in thickness, depending upon application, is initially cut along cut lines 20 to form square-shaped tabs 18 that extend from the skirt 16, as shown in Fig. 3.
  • the strip is shaped and joined at the ends to form a cylinder, and the tabs 18 are bent radially inward in overlapping fashion to form the fuel saver 10.
  • the reason for using either Grade 304 or 316 rather than carbon steel is to avoid stress fractures that may occur because of vehicle and engine vibration.
  • the fuel saver 10 can be fabricated in two possible configurations: a clockwise or a counter-clockwise vortex-producing configuration.
  • the fuel saver 10 For turbo-boosted vehicles, i.e., vehicles including turbo-fans in the inlet and/or the exhaust, the fuel saver 10 creates a vortex that rotates in the same direction as the direction of rotation of the nearest turbo-fan. For non-turbo-boosted vehicles, the fuel saver 10 preferably creates a clockwise vortex, when viewed in the downstream direction.
  • the resulting cylindrical device is placed either inside the vehicle intake line leading to the intake manifold, upstream or downstream of the turbo fan, or inside the exhaust line in an orientation that ensures that the resulting vortex rotation produced by the gases moving through the device is the same as the rotation of the nearest turbo fan.
  • the fuel saver 10 causes intake air to swirl, causing better atomization of fuel in the intake manifold, thereby providing more complete combustion of the air-fuel mixture and increased fuel economy and, in the case of turbo-assisted engines, assists the turbo fan for more power through the complete range of engine speed (i.e., rpm).
  • placement of the device in the intake or fuel-injected engines placement of the device in the intake ensures improved air flow into the combustion chamber.
  • the tabs are offset from the skirt by substantially 45° as this has been observed to provide a measurable increase in fuel economy across a range of engines. It has also been observed that for low-speed engines, such as diesel engines, an increased tab offset tends to provide greater fuel efficiency. Also, for highspeed engines, it has been found that a tab offset of less that 45° has been found to provide improved fuel efficiency. It will be readily apparent to those skilled in the art that the appropriate tab offset angle can be determined by trial and error, with the fuel efficiency, or power output, being monitored as different tab offset angles are used.
  • Some turbo-assisted vehicles are equipped with at least two turbo fans, one placed in the inlet to the engine and another in the outlet, the two axles of the turbo fans being connected directly to each other with a shaft and, in some cases, with additional intervening gears.
  • the resulting inlet-outlet turbo fans have opposite rotations. Therefore, the correct device (i.e., clockwise or counter-clockwise) to use in the inlet or outlet of these vehicles must be selected accordingly as discussed above.
  • the modified vehicle may also include more than one device for greater efficiency, e.g., a device can be installed both before and after each turbo fan for a total of 4 devices.
