Definitions

  • the present invention relates, in general, to exhaust gas discharge devices for discharging exhaust gas, used in internal-combustion engines for vehicles, and more particularly, to an exhaust gas discharge device for vehicles which is coupled to a tail pipe of a silencer provided in an exhaust gas discharge path of a vehicle and is constructed such that the backflow of exhaust gas is restrained by the flow of air, thus preventing back pressure, and rapidly discharging the exhaust gas, thereby reducing fuel consumption and enhancing the output of the engine.
  • a three-dimensional catalytic device which is a gas purification device
  • the flow speed of exhaust gas is markedly reduced while it passes through the gas purification device, having a honeycomb shape, thus creating secondary back pressure.
  • exhaust gas which is drawn into the silencer
  • multi-stepped partition plates to absorb noise, tertiary back pressure is created.
  • the silencer is essential.
  • the silencer is designed to have a capacity that is fifteen to twenty times larger than the engine displacement.
  • an exhaust gas discharge device for vehicles using the flow of air was proposed in Korean Patent Laid-Open Publication No. 2000-56951.
  • This technique using the flow of air, is constructed such that the streamline-shaped body of the exhaust gas discharge device is coupled to a tail pipe, so that when the vehicle travels, a low pressure region is formed around the exhaust gas discharge device by the flow speed of air that passes along the surface of the streamline-shaped body, so that exhaust gas is sucked out by the lower pressure, thus promoting the discharge of exhaust gas.
  • this technique is disadvantageous in that the streamline-shaped body has a relatively large and complex structure affecting the installation thereof, and, when the vehicle is stopped or travels at a relatively low speed, because rapid air flow cannot be induced, the narrow discharge passage interferes somewhat with the discharge of exhaust gas. Therefore, it is very difficult to use this technique in practice.
  • a vortex generating blade is provided at a medial portion in the tail pipe so as to be rotatable by exhaust gas.
  • This technique is constructed such that the blade is rotated by exhaust gas, thus generating vortexes, thereby promoting the discharge of exhaust gas.
  • the blade serves as a source of some resistance that interferes with the flow of exhaust gas, and thus it cannot be used in practice.
  • an exhaust gas discharging device for vehicles which was proposed in Korean Utility Model Registration No.
  • an exhaust gas discharge device is coupled to a tail pipe using locking bolts, and a plurality of vortex generating blades is radially provided on the circumferential inner surface of the pipe.
  • This exhaust gas discharging device was proposed to achieve an improvement in discharge efficiency.
  • vortexes of fluid partially assist the discharge of exhaust gas, which is naturally discharged by exhaust pressure. As such, the efficiency of the device is very low.
  • a vortex generating duct which includes a vane that draws outside air and generates vortexes, is provided on the front pipe of a silencer, which is provided in an exhaust gas discharge path.
  • the exhaust gas discharging device further includes a sub duct, which has therein a valve that adjusts the degree of opening thereof in proportion to the opening degree of a throttle valve.
  • the device is provided with an air regulating damper, which is operated in conjunction with the throttle valve of the engine, so that there is a disadvantage in that the structure thereof is complex. Because outside air, drawn into the duct, passes through the silencer, foreign substances (dust, sand, etc.), which have been contained in the outside air, are deposited in the silencer, thus deteriorating the performance of the silencer.
  • This technique is constructed such that, when a vehicle travels, outside air is gathered using a flared tube, and is used to increase the exhaust pressure in a tail pipe, thus increasing the flow speed of exhaust gas. That is, outside air is supplied into the flared tube to rapidly discharge exhaust gas outside the exhaust pipe using a phenomenon in which the pressure of air is increased when the air flows through a reduced area.
  • This technique realizes an increase in the flow speed of exhaust gas, thus having advantages of enhancing the output of the engine and reducing fuel consumption.
  • a technique was proposed in Korean Patent Application No. 2004-13721, which was filed by the inventor of the present invention, the technique relating to a structure such that two stationary vanes are formed in a tail pipe by cutting and bending portions of the sidewall of the tail pipe inwards, so that the discharge of exhaust gas is promoted, and outside air, which is drawn backwards when the engine is in the valve overlap state, is discharged outside through the vane, thus increasing the output of the engine.
  • a circulation exhaust gas discharge device was proposed in Korean Utility Model Registration No. 374553, which was filed by the inventor.
  • first and second stationary vanes 1 and 2 are formed in the tail pipe of a silencer of a vehicle by cutting and bending portions of the sidewall of the tail pipe inwards.
  • the first and second stationary vanes are disposed at positions spaced apart from each other by a predetermined distance, and face each other.
  • the circulation exhaust gas discharge device includes a housing 3, which covers the first and second stationary vanes such that the first and second stationary vanes communicate with each other therethrough and are isolated from the atmosphere thereby.
  • this exhaust gas discharge device promotes an increase in the flow speed of exhaust gas at the discharge end of the silencer.
  • the inventor of the present invention proposed the above-mentioned techniques and several other techniques, which pertain to the exhaust gas discharge device .
  • the present invention is provided to improve the functions of the conventional techniques proposed by the inventor.
  • An object of the present invention is to provide an exhaust gas discharge device for vehicles, in which exhaust gas discharged through a tail pipe of a silencer is increased in speed by a venturi phenomenon, and outside air drawn thereby is circulated and discharged, thus accelerating the exhaust speed of exhaust gas, thereby making it possible to discharge the exhaust gas more rapidly.
  • Another object of the present invention is to provide an exhaust gas discharge device for vehicles which is constructed such that exhaust gas can be rapidly discharged, and in addition, some exhaust gas, which flows backwards, can be discharged outside the tail pipe along with outside air, which is circulated and discharged, thus preventing exhaust gas from being drawn back into an engine or forming back pressure, thereby increasing the output of the engine.
  • a further object of the present invention is to provide an exhaust gas discharge device for vehicles which has a solid structure, thus markedly increasing the durability thereof, and can be applied to an existing vehicle without changing the construction of the existing silencer, thus having superior intercompatibility.
  • Yet another object of the present invention is to provide an exhaust gas discharge device for vehicles which markedly reduces the backflow of exhaust gas, thus preventing combustion residue, such as carbon, from being deposited, thus extending the lifetime of the engine, and maintaining the components of the exhaust system, including an expensive gas purification device, clear and in a normal state, thereby extending the lifetime of the components .
  • the present invention provides an exhaust gas discharge device for a vehicle, comprising: an extension pipe fitted over the tail pipe of a silencer of the vehicle, with a venturi passage defined in an exhaust gas inlet end of the extension pipe to increase the flow speed of the exhaust gas; an outside air discharge nozzle extending into the venturi passage; a backflow inlet port provided in an exhaust gas outlet end of the extension pipe to guide the inflow of outside air; and a cover fitted over the extension pipe to define therein a chamber, through which the backflow inlet port communicates with the outside air discharge nozzle, so that the flow speed of exhaust gas is increased at the distal end of an exhaust gas discharge path and the backflow of exhaust gas is prevented, thus enhancing the output of the engine.
  • the exhaust gas discharge device is additionally coupled to the tail pipe of a silencer, through which exhaust gas is discharged outside. Therefore, the present invention can be easily applied to an existing vehicle without changing the construction of the existing exhaust system. Furthermore, exhaust gas is rapidly discharged by a venturi phenomenon, and outside air, which is drawn into a chamber of the exhaust gas discharge device and is circulated and discharged outside the vehicle, prevents the backflow of exhaust gas and thus prevents back pressure, thereby improving exhaust efficiency and enhancing the output of the engine.
  • the present invention is designed such that the structures of the outside air discharge nozzle and the backflow inlet port can be changed, so that design of the chamber for forming a low pressure state therein can be easily conducted.
  • the present invention has a solid structure, thus markedly increasing the durability thereof, and can be applied to an existing vehicle without changing the construction of the existing silencer, thus having superior intercompatibility. Moreover, the present invention markedly reduces the backflow of exhaust gas, thus preventing combustion residue, such as carbon, from being deposited, thus extending the lifetime of the engine, and maintaining components of the exhaust system, including an expensive gas purification device, clear and in a normal state, thereby extending the lifetime of the components.

  • a venturi passage 20, which has a relatively small diameter to thus increase the flow speed of exhaust gas, is defined in an exhaust gas inlet end of the extension pipe.
  • Outside air discharge nozzles 30 extend from a surface, defining the venturi passage 20, towards the center of the venturi passage.
  • Backflow inlet ports 40 through which outside air is drawn, are formed in an exhaust gas outlet end of the extension pipe.
  • the circulation exhaust gas discharge device 100 further includes a cover 50, which is fitted over the extension pipe to define therein a chamber 52, through which the backflow inlet port 40 communicates with the outside air discharge nozzle 30.
  • the present invention may further include a subsidiary venturi passage tube 22, which is provided in the venturi passage 20, and the opposite ends of which are increased in diameter. Furthermore, the present invention may be constructed such that the outside air discharge nozzles 30 extend predetermined lengths into the subsidiary venturi passage tube 22, so that the ends of the nozzles communicate with the subsidiary venturi passage tube 22, and the subsidiary venturi passage tube 22 is supported by the nozzles 30 at the center of the venturi passage 20.

Abstract

La présente invention concerne un dispositif d'évacuation des gaz d'échappement pour des véhicules. Ce dispositif d'évacuation des gaz d'échappement comprend un tuyau de prolongement (10) qui est monté sur un tuyau arrière d'échappement du pot d'échappement d'un véhicule. Un passage venturi (20) ménagé dans une extrémité d'entrée de gaz d'échappement du tuyau de prolongement permet d'augmenter la vitesse d'écoulement des gaz d'échappement. Le dispositif d'évacuation des gaz d'échappement comprend également une buse d'évacuation d'air extérieur (30) qui s'étend dans le passage venturi, un orifice d'entrée de retour (40) qui se trouve dans une extrémité de sortie de gaz d'échappement du tuyau de prolongement et permet de guider l'air extérieur, ainsi qu'un capuchon (50) qui définit dans le dispositif une chambre à travers laquelle l'orifice d'entrée de retour communique avec la buse d'évacuation d'air extérieur. Cette invention permet ainsi de restreindre le retour de gaz d'échappement au moyen du flux d'air extérieur, ce qui empêche une contre-pression et permet une évacuation rapide des gaz d'échappement, améliorant alors le rendement du moteur.
