23 Exhaust temperature control EP95108164.5 1995-05-29 EP0759501A1 1997-02-26 Pfefferle, William C.

An emissions control system for rich-burn internal combustion engines, said control system comprising:

  • a. a reaction chamber for oxidation of exhaust gas fuel values,
  • b. passive means to utilize reaction chamber effluent flow energy to mix cooling air into reaction chamber effluent to lower the temperature of said effluent.
  • c. flame arrestor means to prevent ignition of flammable fuel-air mixtures external to the engine.

An emissions control system for rich-burn internal combustion engines, includes a reaction chamber (7) for thermal oxidation of exhaust gas fuel values. A passive means (5, 4) utilizes exhaust flow energy (2) for induction of air into engine exhaust gas, and a duct (3) transfers the exhaust gas together with the inducted air into the reaction chamber (7) for thermal oxidation. To achieve a high degree of efficiency the thermal oxidation is facilitated by thorough mixing of air and exhaust gas by recirculation means (9) to insure gas phase thermal reaction.

A vehicular exhaust resonator features an exhaust inlet conduit which narrows down in a manner such as to define a venturi effect region. Air entrainment apertures in the housing of the resonator provide fluid communication between outside cooling air and an air inlet chamber in the resonator. A further air inlet aperture in an outlet conduit section of the resonator is in fluid communication with the air inlet chamber. Due to the venturi effect inside the inlet conduit, a pressure drop is created to pull air from the outside into the air inlet chamber and then into an outlet conduit of the resonator for mixing with the exhaust gas to provide cooling thereof.

차량용 배기가스 공명기는 벤츄리 효과 영역과 같은 수단에서 좁아지는 배기가스 유입도관을 특징으로 한다. 공명기 내에 공기 유입구는 외부 냉각 공기와 공명기 내의 공기 유입 챔버 사이에서 유체소통을 제공한다. 공명기의 배출 도관 구획에서 추가의 공기 유입구는 공기 유입 챔버와 유체가 통한다. 유입 도관의 벤츄리 효과 때문에, 압력하강이 발생하여 외부로부터 공기 유입챔버로, 그러고 나서 공명기의 배출 도관으로 공기가 끌어들여지며, 배기가스와 혼합되어 냉각에 제공된다.
