Definitions

  • the present invention relates to an exhaust outlet system which is adapted to discharge exhaust gas flow of an internal combustion engine and which comprises exhaust gas dilution and distribution components.
  • an exhaust system enables discharge of exhaust gases resulting from a controlled combustion taking place in the engine of a vehicle.
  • Diesel engines differ from ignition petrol engines in that fuel is compressed and ignited with high temperature.
  • there are dangerous chemical components such as nitrogen oxides (NO x ), carbon monoxide and hydrocarbons in diesel exhaust gas.
  • the main function of the exhaust system is to reduce noise level to a desired acceptable level and to lower the CO, (NO x ) and hydrocarbon component ratios to allowable limits. Therefore, in order to fulfill the above mentioned functions, it is very important to enable the exhaust system to have an adequate performance.
  • the exhaust gas outlet pipe structurally constitutes the outer part of the exhaust system through which the exhaust gases are discharged to the outer environment after the emission is reduced. Temperature of the free exhaust gas is extremely important in order to prevent the released gases having high temperature from harming the outer environment and causing a fire. Furthermore, it should also be noted that animals and humans can be affected by these gases. Another risk that needs to be taken into consideration for the structural parts of the vehicle around the exhaust system is that these parts that are near the exhaust system may burn or melt at high temperatures. In the case that burning or melting does not occur, there is a possibility that the parts cause security problems by expanding uncontrollably due to the rapid air wave coming from the exhaust outlet.
  • the present invention is devised on the basis of the fact that improving the exhaust outlet structure in order to provide a more effective and reliable exhaust gas dilution and distribution device continues to be a necessity.
  • the exhaust dilution and distribution device of the present invention protects the vehicle parts surrounding the exhaust dilution and distribution device while it also aims to eliminate the safety risks that may arise due to flying of various objects such as hay, debris or wooden pieces or smaller particles located on the ground or road.
  • the speed of the exhaust gases released from the exhaust tail pipe may have the impact of raising dust to an extent of restricting visibility of a driver of a rear vehicle in the traffic.
  • the present invention enables the exhaust gas to be discharged to the atmosphere in a more reliable manner by means of communication with a wider and more effective discharge plane.
  • the present invention enables to prevent undesired particle scattering by diverting the exhaust gas at a specific angle by means of its special grille structure whose vanes are designed at specific angles.
  • the main objective of the present invention is to provide an exhaust dilution and distribution device which is structurally improved to prevent any harm in the outer environment caused by the dust or other particles which are rapidly moved from the ground by the exhaust gas flow to unpredictable places.
  • Another objective of the present invention is to protect the vehicle parts surrounding the exhaust dilution and distribution device while also eliminating the safety risks that may arise due to flying of various objects such as hay, debris or wooden pieces or smaller particles located on the ground or road.
  • a further objective of the present invention is to ensure that the speed of the exhaust gases released from the exhaust tail pipe do not have the impact of raising dust to an extent of restricting visibility of a driver of a rear vehicle in the traffic.
  • Another objective of the present invention is to enable the exhaust gas to be discharged to the atmosphere in a more reliable manner by means of communication with a wider and more effective discharge plane.
  • a further objective of the present invention is to enable preventing undesired particle scattering by diverting the exhaust gas at a specific angle by means of its special grille structure whose vanes are designed at specific angles.
  • the present invention relates to an exhaust dilution and distribution device (11) for a combustion engine, wherein the said exhaust dilution and distribution device (11) comprises, as will be described below in detail, an inner pipe (18) in the form of an exhaust passage component which is in flow communication with the combustion engine components going to an outlet housing (15).
  • the combusted gas is received via the cylindrical inner pipe (18), which generally extends longitudinally, and transferred to the outlet housing (15).
  • the two components i.e. the said inner pipe (18) and the said outlet housing (15) form an air flow connection so as to establish a flow connection therebetween via a connecting member (25), they contribute to the decrease in the exhaust gas flow rate as will be described in detail later, and again as will be described below, flow orientation parallel to the ground is established by means of an exhaust grille (12).
  • the diametrical ratios of the outlet housing (15) inlet and the inner pipe (18) are determined preferably as 0.9, and a structure wherein the cylindrical forms are engaged to each other is configured.
  • the discharged exhaust gas is allowed to interact with free air flow and the exhaust gas flow is adequately blended with free air and the gas flow is effectively directed towards a single outlet plane (14).
  • the semi closed form of the outlet housing (15) reaches the outlet plane (14) which extends parallel to the ground.
  • the closed volume of the outlet housing (15) effectively transmits the exhaust gas to the outlet plane (14) of the housing.
  • the outlet housing (15) comprises a first lobe (19) and a second lobe (20), and each of the lobes comprises a first lobe and a second lobe opening (21, 22) respectively.
  • the outlet opening formed by the first lobe and second lobe openings (21, 22) enables the exhaust gas to leave the system directly towards the ground and with a decreased flow rate.
  • the air, whose flow rate is decreased by means of the first lobe and second lobe openings (21, 22) is directed parallel to the ground by means of the exhaust grille (12). Below is described in detail how the said exhaust grille (12) fulfills the mentioned function.
  • the closed structure of the outlet housing (15) extends between the inlet and outlet plane (14). Therefore, the outlet housing (15) is adapted such that it will communicate with the longitudinal axis of the inner pipe (18) and that it will extend along the surface normal of the outlet housing (14) perpendicular to the longitudinal axis of the inner pipe (18).
  • the outlet plane (14) is perpendicular to the inlet plane of the outlet housing (15). While the first and second lobes (19, 20) are separated by a diverting part (24) protruding inwards and expanding downwards, the outlet housing (15), in a general manner, structurally expands towards the outlet plane (14).
  • the diverting part (24) seen in Figure 1 is configured to directly receive thereon the gas flows coming to the inner pipe (18) via the inlet pipe, and by means of the asymmetry of the first and the second lobes (19, 20) relative to each other, it enables to form discrete swirls and reduces the flow rate of the discharged gas.
  • the outlet housing (15) is designed to include tangent walls (23) which receive the exhaust flow coming directly from the top and which create swirls by directing the gases tangentially by means of the asymmetrical form of the first and the second lobes (19, 20).
  • the exhaust gas hits the tangent walls (23) of the first and the second lobes (19, 20), and orientation of the gas mass flow in an asymmetrical manner causes formation of a higher pressure flow region along the tangent wall (23) of the first lobe (19) whose projective diameter is bigger than that of the second lobe (20).
  • Momentum of the exhaust gas flow is used by dividing the exhaust gas flow in order to improve mixing process and to reduce the flow rate of the discharged gas; and by creating asymmetrical separated swirling areas at the side of the tangent walls (23) of the first and the second lobes (19, 20).
  • the exhaust grille (12) installation can be carried out by two different ways, namely by direct welding and by mounting with the help of grille fixing screws (16).
  • the grille vanes (13) can be designed to receive the incoming flow accurately instead of being designed as being disposed at equal intervals.
  • the flow is received accurately thereby leaving the system more parallel to the ground.
  • An example of the flow reception form of the angle ⁇ is given in Figure 3 .
  • the angle between the flow coming direction and a plane parallel to the outlet plane (14) is defined as the vane flow reception angle ( ⁇ ), and ⁇ is less than 82 degrees.
  • the flow received by the said coming angle is directed by the grille vane (13) such that it will have a trailing angle ( ⁇ ) parallel to the ground.
  • the guides wherein the surface perpendicular to the coming flow is as low as possible, perform guidance with less loss compared to the ones which receive the flow perpendicularly inhibiting the flow.
  • An example to the flow separation phenomena is given in Figure 3 .
  • an exhaust grille (12), an outlet housing (15) and a heat shield (26) can be seen.
  • the said heat shield (26) is disposed on a dirty part pipe which is one of the air intake components of passenger vehicles.
  • the grille fixing slots (17) placed on the heat shield (26) the exhaust grille (12) can be fixed to the slots by using grille fixing screws ((16).
  • the grille vanes (13) in the first lobe (19) and the grille vanes (13) in the second lobe (20) transfer the incoming exhaust gas to directions opposite to each other.
  • the sectional profile of the said grille vanes (13) can be in an arc form having a radius of curvature as shown in Figure 4 , it can also be in the form of linear segments having a plurality of levels. In a structure having a plurality of segments, the angle of each consecutive segment relative to a plane parallel to the said outlet plane (14) will decrease respectively.
  • the number of leveled linear segments in the section of the said grille vane (13) can be preferably three.
  • Figure 7 shows at least one grille vane with at least one pair of segments.
  • the grille vanes (13), which remain within the outlet plane (14) sections located at the projection of both of the lobes in accordance with the asymmetrical lobe structure, are symmetric according to an imaginary line separating the two lobes on the outlet plane (14).
  • curvature centers of the grille vanes (13) in each lobe are at opposite sides. This situation points out to the asymmetrical structure wherein the exhaust grille (12) is designed to discharge exhaust gas parallel to the ground.
  • this enables to discharge the exhaust gas, which is released from between the vanes to the atmosphere at a specific trailing angle, parallel to the ground however with an asymmetrical flow rate, i.e. in a manner wherein its power is dissipated.
  • the present invention is an exhaust dilution and distribution device (11) for an internal combustion engine and the exhaust dilution and distribution device (11) comprises an exhaust grille (12) which enables the exhaust gases to flow parallel to the ground via an outlet housing (15) which directs and transfers the exhaust gases resulting from combustion towards an outlet plane (14).

  • Another embodiment of the present invention comprises a diverting part (24) which extends between the said first and second lobe (19, 20) towards the outlet plane (14) and which is configured to decrease the flow rate of the exhaust gas by creating asymmetrical separate swirls of the divided exhaust gas flow within the first and second lobes (19, 20).
  • Another embodiment of the present invention comprises tangent walls (23) of the first and second lobes (19, 20) to which the exhaust gas hits and which produce a tangent and asymmetrical high pressure area within the first lobe (19) by mass flow.
