Definitions

  • the present invention relates to device for mixing and exhausting the burned gas utilized in an internal combustion engine with an external air, and more particularly, to an exhaust gas and air- mixing device operating with the airflow created by an ejector type mixer.
  • a vehicle using an internal combustion engine obtains a driving power through the four-stroke cycle consisting of the intake stroke, the compression stroke, the combustion stroke, and the exhaust stroke.
  • the flow rate of the exhaust gas is so remarkably reduced that a secondary exhaust pressure is generated when the exhaust gas passes through fine holes of a HoneyCom style exhaust gas cleaner, and the exhaust gas is introduced into the muffler to generate a third exhaust pressure when exhaust gas passes through partitions for partitioning the muffler into multiple spaces so that sound is absorbed by the muffler.
  • the muffler Since the exhaust gas is exhausted at a pressure of 3 to 5 kg/cm and at about 600 degrees centigrade during this exhaust process, the muffler is essential.
  • the muffler is designed to have fifteen to twenty times the volume of an engine. Since the exhaust gas cannot be exhausted through the muffler due to air resistance, the torque of the engine is reduced by 5 to 10 percent.
  • Korean Patent Laid-Open No. 2000-56951 proposes an exhaust vessel of a vehicle using an air stream, generated when the vehicle is traveling.
  • a streamline body of the exhaust vessel is coupled with the tail pipe such that there is formed a lower pressure region by air stream rapidly passing through the streamline body and the exhaust gas is rapidly suctioned into the exhaust vessel to help the exhaust of the exhaust gas due to the lower pressure.
  • the conventional exhaust vessel of a vehicle is too large and complex to install the streamline body on the vehicle. Moreover, since it cannot create the air stream when a vehicle is stopped or traveling at a low speed, narrow exhaust passages instead disturbs the exhaust of the exhaust gas. Thus, it is difficult to put the conventional exhaust vessel to practical use.
  • a tail pipe of a main silencer having a vortex generator disclosed in Korean Patent Laid-Open No. 1998-75223, vortex blades are provided in the mid section of the tail pipe to be rotated by the exhaust gas such that the vortex blades are rotated by the exhaust gas to generate the vortex and exhaust the exhaust gas.
  • this structure instead causes resistance and disturbs the stream of the exhaust gas.
  • a pipe is provided to be attached to an end of a tail pipe by screws and a plurality of blades for generating vortex are formed in the inner circumference of the pipe in the radial direction such that the exhaust gas is converted into vortex to improve exhaust efficiency.
  • the structure of forming the exhaust gas into a vortex is not sufficient to rapidly and smoothly exhaust the exhaust gas, its effect being insignificant and only partially helping to form the exhaust vortex in addition to the natural exhaust due to the exhaust pressure, and thus the efficiency is very low.
  • an exhaust gas-discharging device using vortex generating duct is provided in a front pipe of a muffler installed on the exhaust gas path and includes a vane for introducing external air and forming a vortex, and a sub-duct includes a valve of which an opening degree is adjusted in proportion to an opening degree of a throttle valve.
  • the duct through which the external air is introduced is installed in the front pipe of the muffler for eliminating exhaust noise, the exhaust noise escapes to the duct so that noise is louder.
  • the valve is opened widely when accelerating so that the exhaust noise is louder.
  • the exhaust gas is exhausted to the sub-> duct having lower air resistance than that of the inside of the muffler, the introduced air meets resistance so that it is difficult to put the exhaust gas-discharging device to practical use.
  • the present invention is proposed to improve the devices disclosed above.
  • the present invention has been made in view of the above problems and of improving the related devices filed by this applicant of the present invention and their efficiency, and it is an object of the present invention to provide an exhaust gas and external air mixing device of a vehicle in which exhaust gas exhausted through a tail pipe of the muffler generates a jet stream, which leads the air into the ejector, in which the exhaust gases are led out, in such a way that the air is entrained out by the exhaust gases through an ejector effect which the exhaust gases exert on the air.
  • an ejection exhaust system of a vehicle including: first substantially decrease the concentration of CO 2 and HC in exhaust after devise and secondly an exhaust gas-discharging device of a vehicle rapidly exhausting exhaust gas that the valve overlap is prevented and torque of the engine is increased.
  • the exhaust speed of the exhaust gas, discharged through a tail pipe of a muffler through which the exhaust gas is discharged is increased together with the external air being rapidly introduced such that the exhaust gas is rapidly exhausted so that the vehicle is effectively accelerated and the hill climbing ability of the vehicle is also increased.
  • the valve overlap which causes the exhaust gas to be reintroduced into an engine, is prevented and torque of the engine is increased.
  • the structure is simple and strong, the endurance thereof is remarkably increased and it is capable of being applied to a vehicle without a structural change of the conventional muffler so that the compatibility is excellent.
  • it prevents the exhaust gas and pollutants such as carbon from being reintroduced so that a lifespan of the engine is prolonged and various components such as an exhaust gas purifier of the exhaust system are maintained clean and their lifespan is also prolonged.
  • Fig. 1 is a sectional view illustrating an ejection exhaust system of a vehicle as a conventional art filed by this inventor of this application.
  • FIG. 1 shows an alternative embodiment of the arrangement according to the invention, in which the tailpipe 50 connected into the chamber 20.
  • the air baffle element 60 extends through the chamber 20 and, as previously, into the tailpipe 50.
  • the air baffle element 60 in this case projects right through the chamber
  • the air baffle element may obviously be of some design shape other than that described above.
  • the chamber 20 is preferably, but need not necessarily be arranged above some heavily heat-affected component.
  • the inlet to the air baffle element is the part which should be arranged in proximity to such a component.
  • Fig. 1 shows an ejection exhaust system of vehicle according to a basic preferred embodiment of the present invention.

Abstract

La présente invention concerne un système d'échappement entraînant de l'air extérieur dans les gaz d'échappement par le biais d'un effet d'éjection exercé par les gaz d'échappement sur l'air dans la conduite de sortie (30), et pour laisser s'échapper les gaz brûlés d'un tuyau de silencieux arrière (40), à l'aide de la voie de déchargement d'un véhicule, pour améliorer l'efficacité du carburant et le couple moteur du véhicule. Le dispositif est pourvu d'une admission d'air permettant de faire entrer de l'air extérieur dans le système d'échappement et d'entraîner de l'air extérieur dans les gaz d'échappement. L'admission d'air comprend un élément de déflexion d'air (60) qui conduit l'air dans une zone essentiellement centrale dans une conduite de sortie (30) d'où ressortent les gaz d'échappement, de façon à ce que l'air soit entraîné vers la sortie par les gaz d'échappement par l'intermédiaire d'un effet d'éjection exercé par les gaz d'échappement sur l'air contenu dans la conduite de sortie (30).
