Definitions

  • the present invention is related generally to the field of internal combustion engine exhaust gas recirculation (EGR) for emissions improvement. More particularly, the invention provides a mixer for entraining the recirculated exhaust gas in the charge air for the engine for combination with a turbocharger having a compressor wheel with impeller vanes mounted on a side opposite the compressor impeller to act as an EGR pump with a separate diffuser and volute for EGR flow output from the pump and a separate scroll inlet to the EGR pump and a control valve for metering exhaust gas to be recirculated.
  • EGR exhaust gas recirculation
  • EGR is a known method for reducing the NOX emissions in internal combustion engines.
  • an EGR system must overcome the adverse pressure gradient created by a positive pressure gradient across the engine which is typical of modern high efficiency diesel engines in at least a portion of their operating range.
  • Various approaches to implementing EGR have included pumping of a portion of the exhaust gas from the exhaust manifold to the intake manifold. Pumping has been accomplished by introducing the exhaust gas into the compression inlet of a conventional turbocharger or supercharger present on the engine or, alternatively, providing a separate compressor receiving the exhaust gas and pressurizing it to a suitable pressure for insertion into the charge air downstream of the charge air boosting system on the engine.
  • EGR also requires adequate mixing of recirculated exhaust gas with the incoming fresh air charge to avoid performance degradation and to minimize mixing losses to avoid additional fuel consumption penalties. Further, positive control of the recirculated exhaust gas flow is required to assure proper proportions in the charge air mixture supplied to the engine intake manifold under varying operating conditions. Additionally, the components and features of an EGR system must be accommodated within the constraints of limited volume available for allocation in modern engine compartments.
  • a mixer for an EGR system for an internal combustion engine includes a substantially cylindrical body having a charge air inlet and an EGR inlet to a volute circumferentially distributed about the cylindrical body downstream from the charge air inlet.
  • the volute introduces recirculated exhaust gas uniformly about the circumference of the fresh air flow path through a slot to promote both penetration into the core flow stream and a swirl to further mix the flow downstream.
  • a mixed flow outlet is attached to the intake manifold of the engine.
  • the volute slot has a tailored upstream lip of relatively smaller diameter and a downstream lip of relatively larger diameter to produce a three dimensional angle for the EGR flow into the core flow.

  • FIG. 1 shows an internal combustion engine 10 having an intake manifold 12 and an exhaust manifold 14.
  • a turbocharger 16 is provided for charge air boost, receiving intake air for compression by a compressor rotor 18 which provides the pressurized air to a charge air cooler 20 prior to introduction into the intake manifold.
  • the compressor rotor is driven by a shaft 22 connected to a turbine 24 receiving exhaust gas from the exhaust manifold of the engine.
  • Exhaust gas for recirculation is diverted from the flow out of the exhaust manifold through a control valve 26 to an EGR cooler 28.
  • Gas from the EGR cooler is provided to the inlet of an EGR pump which, for the embodiment shown in the drawings, is a compressor rotor 30 mounted to the turbocharger shaft to be driven by the turbine.
  • the pressurized exhaust gas from the EGR pump flows to a mixer 32 which combines the recirculated exhaust flow with the charge air to create a substantially homogenous flow stream for introduction into the intake manifold.

  • the turbine is contained in a cast turbine housing 34 which inco ⁇ orates a radial exhaust gas inlet 36 feeding a bifurcated volute 38, for the embodiment shown in the drawings. Gas flowing through the turbine exits at turbine outlet 40.
  • Shaft 22 is supported by a bearing system including journal bearings 42 separated by spacer 44 and thrust collar 46 with bearing 48 all carried within a center housing 50 which inco ⁇ orates lubrication channels 52.
  • the charge air compressor is contained within a cast compressor housing 54 which provides an air inlet 56, a diffuser 58 and a volute 60 for the compressed charge air.
  • the EGR pump is inco ⁇ orated into the existing rotor group of the turbocharger by adding impeller vanes 62 to the back side of the compressor wheel.
  • a scroll inlet 64 provides exhaust gas for recirculation and a separate diffuser 66 carries the pressurized exhaust gas to a volute 68.
  • the EGR pump inlet, diffuser and volute are inco ⁇ orated in a casting 70 which replaces the conventional compressor back plate for the turbocharger, thereby requiring only a small increase in the length of the rotor group and turbocharger as a whole. Segregation of the charge air flow in the compressor and the recirculated exhaust gas in the EGR pump is maintained by a baffle 72 which is constrained between the compressor housing and EGR pump casting.
  • the EGR pump casting is mounted to the compressor housing using a retaining ring 74 and bolts 76 received in the compressor housing.
  • Pressurized exhaust gas from the EGR pump and pressurized charge air from the turbocharger compressor and charge air cooler are combined in mixer 32 which is shown in detail in FIG. 3.
  • Exhaust gas from the pump is introduced to the mixer through an inlet 78 to a volute 80 circumferentially distributed about the main fresh air flow path entering through inlet 82 from the charge air cooler.

  • Exhaust gas for recirculation is provided to the EGR pump through control valve 26.
  • FIG.s 4 and 5 describe the mechanical configuration and operation of one embodiment of the valve.
  • a proportional electrical solenoid 94 acts on a three-way pneumatic or hydraulic valve 96 with opposing force provided by a piston or diaphragm 97 which is, in turn, acted on by a differential pressure generated by the flow through a separate exhaust gas recirculation valve 98.

  • the three way valve provides supply air from line 104 to an actuator 106 for the EGR valve or vents actuator air through vent 108.
  • the three-way valve When the force of the piston is not sufficient to balance the force of the solenoid, the three-way valve opens to supply air to the actuator, thus increasing the EGR flow from the primary exhaust flow line 110 through the EGR valve into the EGR flow line 112 and thus increasing the differential pressure across the valve, restoring the balance of forces. Conversely, when the force of the piston is greater than the force of the solenoid, the three-way valve opens to vent air from the EGR valve actuator, thus decreasing the EGR flow and the differential pressure across the valve, again restoring the balance of forces. As shown in FIG.
  • the EGR valve actuator for the embodiment shown in the drawings, employs a diaphragm 114 and spring 116 enclosed in a pressure case 118, which position a shaft 120 for controlling valve poppet 122 on seat 124 to meter EGR flow.
  • the three way valve employs a multi port body 126 inco ⁇ orating the supply and vent

Abstract

L'invention concerne un dispositif de mélange (32) pour un système de gaz d'échappement recirculés (EGR) destiné à un moteur à combustion interne (10) qui comprend un corps sensiblement cylindrique présentant une entrée d'air de suralimentation (82) et une entrée EGR (78) en direction d'une volute (80) répartie de manière périphérique le long du corps cylindrique en aval partir de l'entrée d'air de suralimentation (82). La volute (80) introduit les gaz d'échappement recirculés uniformément le long de la périphérie du trajet d'écoulement de l'air frais à travers une fente (84) afin de permettre sa pénétration dans le flux primaire et le tourbillon afin de mélanger l'écoulement en aval. Une sortie d'écoulement mélangé (92) est relié au collecteur d'admission (12) du moteur (10). La fente (84) de la volute présente une lèvre en amont (86) présentant un diamètre relativement plus petit et une lèvre en aval (88) dont le diamètre est relativement plus grand afin de former un angle tridimensionnel pour l'écoulement EGR dans le flux primaire. Une buse convergente (90) se trouvant dans le corps cylindrique en amont de la fente augmente le débit d'air de suralimentation afin d'améliorer le mélange et la pénétration de l'écoulement EGR en provenance de la volute (80). Une buse divergente (91) en aval de la fente permet de réguler par ailleurs le débit et de faire correspondre la vitesse pour l'air de suralimentation mélangé acheminé vers le collecteur d'admission (12) du moteur.
