  • the present invention relates to an exhaust dilution and dispersion device (11) for an internal combustion engine of a vehicle, said exhaust dilution and dispersion device (11) comprising an inner pipe (12) in the form of an exhaust passage component in flow communication with the combustion engine components leading to an outlet enclosure (IS) as will be described hereinafter.
  • the combustion exhaust is received and directed to the outlet enclosure (IS) through the inner pipe (12) generally in the form of a longitudinally extending tubular element.
  • the inner pipe (12) and the inlet of the outlet enclosure (IS) proximate the inner pipe (12) are adapted to be connected with at least one dilution gap (18) effecting air intake into the system.
  • the inner pipe (12) and said outlet enclosure (IS) communicate with each other by means of a connection element (13) joining the two components while creating air intake gaps substantially contributing to the temperature drop of the exhaust gas streams as will be explained in more detail hereinafter.
  • said inner pipe (12) and the inlet of said outlet enclosure (IS) are configured as cylindrical bodies cooperatively fitted to each other with a diametric ratio being specified as 0.9.
  • a semi-closed gas stream processing chamber is created in the manner that the closed volume increases surface area of metal-gas contact so that enhanced heal transfer is ensured. It is to be noted that gas discharge is appropriately delayed to allow the exhaust gas to interact with free stream air thanks to the structural performance of the outlet enclosure (IS), by which gas flow is directed to a singular outlet plane (14).
  • the outlet enclosure (IS) of the invention has a semi-closed structure leading to the outlet plane (14) that is oriented to extend parallel to the ground. In other words, the exhaust gases mixed with the atmospheric air is discharged in the manner to be directly facing the road surface the vehicle moves.
  • the closed volume of the outlet enclosure (IS) efficiently directs the exhaust gases to the outlet plane (14) of the outlet enclosure (IS) exit.
  • the outlet enclosure (15) has a first lobe (19) and a second lobe (20), each of the lobes respectively having a first lobe and second lobe openings (21, 22).
  • the exit opening formed by the first lobe and second lobe openings (21, 22) provides that the exhaust flow leaves the system directly facing the ground and in a sufficiently cooled state.
  • the closed structure of the outlet enclosure (15) is formed between the inlet and the outlet plane (14) thereof. Therefore the outlet enclosure (15) is adapted to extend along the longitudinal axis of the inner pipe (12) and the surface normal of the outlet plane (14) perpendicular to the longitudinal axis of the inner pipe (12). In other words, the outlet plane (14) is perpendicular to the plane of the inlet of the outlet enclosure (15).
  • the outlet enclosure (15) structurally expands in the direction of the outlet plane (14) while the first and second lobes (19, 20) are separated by an inwardly projecting and downwardly expanding deflection portion (24). As can be seen in Fig.
  • the outlet enclosure (15) as well as the deflection portion (24) is in the form of an arc- shaped extension.
  • the deflection portion (24) is structured to directly face and receive gas streams coming from the inlet pipe (12) through the upstream pipe (17) in the manner that, due to the asymmetry of the first and second lobes (19, 20) with respect to each other, separate vortices are created as demonstrated in Fig. 6.
  • the outlet enclosure (15) is structured to have tangential walls (23) which directly receive the upstream hot exhaust gas flow, which is tangentially guided to create vortices due to the asymmetric configuration of the first and second lobes (19, 20).
  • the upstream hot exhaust gas hits the tangential walls (23) of the first and second lobes (19, 20) in the manner that bulk flow of the gas is asymmetrically guided to create a higher pressure area along the tangential wall (23) of the first lobe (19) whose projected diameter is greater than that of the second lobe (20) (Fig. 5).
  • the surface pressure distribution graph of the tangential walls (23) of the first and second lobes (19, 20) is seen in Fig. 7. Accordingly, the momentum of the exhaust gas flow is utilized to enhance the mixing process by dividing the exhaust gas flow and creating asymmetrically separated vortex regions as defined by the tangential walls (23) of the first and second lobes (19, 20).
  • separated vortex regions provide the atmospheric air to be taken into the outlet enclosure (15) to be effectively mixed with the hot exhaust gas within the closed volume of the outlet enclosure (IS).
  • an enhanced vortex flow is generated, which in turn creates secondary vortices to entrain fresh air from outside the outlet enclosure (15).
  • the eccentricity of the first lobe (19) with respect to the longitudinal axis of the inner pipe (12) on the plane along the longitudinal axis of the same in parallel with the outlet plane (14) of the exhaust diluting and dispersing device (11) provides that the bulk flow of the gas is asymmetrically guided to create a higher pressure area along the tangential wall (23) of the first lobe (19).
  • the eccentricity of the first lobe (19) with respect to the longitudinal axis of the inner pipe (12) can be also defined in that the diameter of the inner pipe (12) on the plane along the longitudinal axis of the inner pipe (12) in parallel with the outlet plane (14) of the exhaust diluting and dispersing device (11) (from a section parallel to the ground) is determined to be equal to the diameter of the first lobe (19) on that plane (Fig. 9). Further, the eccentricity of the first lobe (19) with respect to the longitudinal axis of the inner pipe (12) is defined as 0.8 times the radius of the first lobe (19) on that plane (Fig. 9).
  • the exhaust dilution and dispersion device (11) in accordance with the present invention is mounted to be situated along a longitudinal edge of the vehicle such that the first lobe (19) is configured to be near the longitudinally front side of the vehicle.
  • This is advantageous in that the exhaust gas transferred from the front of the vehicle to the exhaust dilution and dispersion device (11) via the upstream pipe (17) is largely discharged from a more frontal side compared to the second lobe (20) whereby the bulk flow of the exhaust gas being sufficiently cooled thanks to the cooling effect of the secondary vortices created by the first lobe's (19) structural configuration as well as thanks to the effect of the air taken through the dilution gaps (18), even has more time and space to further cool down as it passes along under the second lobe (20).
  • the structure of the outlet enclosure (15) widening as it closes to the ground provides a wider exit area as diameters of both lobes get larger towards their ends.
  • the first lobe opening (21) as well as the second lobe opening (22) has larger diameters compared to their initial upper parts. As vortex mechanisms are asymmetrical in terms of the gas stream volume, gas discharge from the second lobe opening (22) is less dense in volume compared to the first lobe opening's (21) performance.
  • Fig. 3 demonstrates an alternative connection element (13) between an inner pipe (12) and an outlet enclosure (15), such a connection element (13) having a plurality of peripherally distributed radially equally-spaced wings.
  • the air flowing through the dilution gaps (18) allows atmospheric air to be drawn into the system. It is worthy of note that this gas flow regulating mechanism does not involve a venturi geometry.
