  • Air-fuel ratio sensor 16 is mounted to a relatively downstream portion of downstream exhaust pipe 9 and located along partition wall 10 so as to partially project into both of passages 11 and 12 through cutout 18 formed in partition wall 10.

  • partition wall 10 extends over an entire axial length of downstream exhaust pipe 9.
  • Partition wall 10 includes a communication portion fluidly communicating passages 11 and 12 with each other.

  • the communication portion is in the form of inclined slit 21 that is located on an upstream side of air-fuel ratio sensor 16.
  • Slit 21 extends in the width direction of partition wall 10, namely, in a left-and-right direction in FIG.
  • slit 21 has one end 21A positioned on the one side of partition wall 10 in the width direction and the other end 21B positioned on an opposed side of partition wall 10 in the width direction.

  • One end 21A is located on a downstream side relative to the other end 21B.
  • slit 21 has a uniform width in a direction perpendicular to the width direction of partition wall 10. Slit 21 can be suitably modified such that the width is varied between the upstream side and the downstream side in order to adjust pressure distribution. Further, slit 21 can be in the form of a plurality of slits.
  • downstream exhaust pipe 9 has a generally circular shape in section.
  • Partition wall 10 is disposed within downstream exhaust pipe 9 so as to contain the central axis of downstream exhaust pipe 9.
  • Partition wall 10 divides the exhaust path within downstream exhaust pipe 9 into passages 11 and 12 each having a generally semicircular-shaped section.
  • the downstream ends of two branches 5 and 8 connected with engine cylinders #1 and #4 that have non-continuous order of ignition are connected with the upstream end of downstream exhaust pipe 9 so as to be communicated with quarter-circular regions A and B, respectively, which cooperate to form the semicircular-shaped section of passage 11.
  • Quarter-circular regions A and B are thus in fluid communication with engine cylinders #1 and #4 via branches 5 and 8, respectively.
  • One end 21A of slit 21 is located near the middle of a portion of partition wall 10 which extends between regions B and D in the width direction thereof.

  • FIGS. 5A and 5B there is explained a stream of the exhaust gas discharged from engine cylinder #1 into passage 11 of downstream exhaust pipe 9 and then flowing into passage 12 through slit 21.
  • FIG. 5A shows the stream of the exhaust gas discharged from engine cylinder #1 and flowing into passage 11.
  • FIG. 5B shows the stream of the exhaust gas flowing from passage 11 into passage 12 via slit 21.
  • a part of the exhaust gas passing through region A of passage 11 is caused to flow into passage 12 via slit 21 as shown in FIG. 5B.
  • the part of the exhaust gas flows along the inclined periphery of slit 21.
  • the part of the exhaust gas then enters into passage 12 and flows toward air-fuel ratio sensor 16 in a dispersed state as shown in FIG. 5B.
  • slit 21 forms a certain low-pressure portion. Since slit 21 is inclined such that the downstream side of slit 21 is closer to air-fuel ratio sensor 16, namely, the low-pressure portion on the downstream side is more offset toward air-fuel ratio sensor 16 than that on the upstream side, the stream of the exhaust gas flowing in region A is caused to divert to region B disposed close to air-fuel ratio sensor 16, in a dispersed state as shown in FIG. 5A. Thus, the amount of the exhaust gas emitted from engine cylinder #1 and coming into contact with air-fuel ratio sensor 16 is increased. As a result, air-fuel ratio sensor 16 can detect the exhaust gas emitted from engine cylinder #1 with an increased accuracy.
  • a stream of the exhaust gas discharged from engine cylinder #2 into passage 12 of downstream exhaust pipe 9 and then flowing into passage 11 via slit 21 is symmetric with respect to the above-explained stream of the exhaust gas discharged from engine cylinder #1 into passage 11.
  • the exhaust gas emitted from engine cylinder #2 flows into region C of passage 12 via branch 6.
  • passage 11 has a lower pressure caused immediately after the exhaust gas emitted from engine cylinder #1 passes through passage 11. Therefore, a part of the exhaust gas passing through region C of passage 12 is caused to flow into passage 11 via slit 21.
  • the part of the exhaust gas is caused to flow toward air-fuel ratio sensor 16 in a dispersed state.
  • slit 21 forms the low-pressure portion, the stream of the exhaust gas flowing in region C is caused to divert to region D disposed close to air-fuel ratio sensor 16, in a dispersed state. Further, a part of the exhaust gas discharged from engine cylinder #4 into region B of passage 11 is caused to disperse into passage 12 via slit 21. A part of the exhaust gas discharged from engine cylinder #3 into region D of passage 12 is caused to disperse into passage 11 via slit 21.
  • FIGS. 6A and 6B there is shown the stream of the exhaust gas flowing toward catalytic converter 3 and impinging on ceramic monolithic carrier 3A.
  • FIG. 6A illustrates the stream of the exhaust gas which is caused when partition wall 10 without slit 21 is used.
  • FIG. 6B illustrates the stream of the exhaust gas which is caused when partition wall 10 with slit 21 is used.
  • the exhaust gas emitted from engine cylinders #1 and #4 passes through only passage 11.
  • the exhaust gas flows from passage 11 toward catalytic converter 3 via diffuser 14 and is diffused at a portion of diffuser 14 which is disposed on the side of passage 11.
  • exhaust manifold 2 of the present invention can prevent interference of the exhaust gases emitted from four cylinders #1 to #4. Further, the exhaust gas flowing in downstream exhaust pipe 9 can be detected with an enhanced accuracy by single air-fuel ratio sensor 16. Specifically, in a case where inclined slit 21 is formed in partition wall 10, the exhaust gases flowing from branches 5 and 6 positioned away from air-fuel ratio sensor 16 are caused to flow and deflect toward air-fuel ratio sensor 16. This can enhance the accuracy of detecting the exhaust gas in downstream exhaust pipe 9 by means of air-fuel ratio sensor 16. Further, the exhaust gas can be widely diffused from downstream exhaust pipe 9 toward catalytic converter 3. This prevents the exhaust gas from impinging on only a part of the inlet portion of catalytic converter 3. Thus, exhaust manifold 2 of the present invention can achieve homogeneous impingement of the exhaust gas on a wide area of carrier 3A of catalytic converter 3.
  • FIG. 7 a second embodiment of exhaust manifold 2 of the present invention is explained.
  • the second embodiment differs in that the partition wall has a plurality of holes from the first embodiment.
  • three holes 22, 23 and 24 are formed in partition wall 110 and act as the communication portion for fluid communication between passages 11 and 12.
  • three holes 22, 23 and 24 have a same diameter.
  • Three holes 22, 23 and 24 are arranged along an inclined line relative to the axial direction of downstream exhaust pipe 9 and the width direction of partition wall 110.
  • Middle hole 23 between holes 22 and 24 is arranged across boundary plane M.
  • Hole 22 is located on a downstream side of middle hole 23 and on the one side of partition wall 110 in the width direction on which air-fuel ratio sensor 16 is arranged.
  • Hole 22 is located in the middle of a portion of partition wall 110 which extends between regions B and D. Hole 22 is open to both of regions B and D. Hole 24 is disposed on an upstream side of middle hole 23 and on the opposite side of partition wall 110 in the width direction. Hole 24 is located in the middle of a portion of partition wall 110 which extends between regions A and C. Hole 24 is open to both of regions A and C. These holes 22, 23 and 24 are so arranged as to act substantially equivalent to slit 21 of partition wall 10 of the first embodiment.
  • the plurality of holes acting as the communication portion are not limited to this invention.
  • the diameter of the holes can be set different from one another by considering pressure distribution. Further, the number of the holes may be not limited to three in this embodiment. A larger number of holes can be arranged in multiple lines.
  • the exhaust manifold of the second embodiment can perform the same effects as explained in the first embodiment.
