Definitions

  • the reductant system 16 may also include a reductant source 54, pump 56, and valve 57.
  • the reductant 19 is drawn from the reductant source 54 via the pump 56 and delivered to an inlet connection 58 on the nozzle 18.
  • the valve 57 or pump 56 may be used to control the delivery of the reductant 1 .
  • a controller and sensors may also be included to control the reductant system 16.
  • the controller and sensors may also control the heat source 30.
  • the controller may also be in communication with an engine control module (ECM) or may be included in the ECM.

  • bend 24 may also include double walls 82 outside of these walls. The double walls 82 provide thermal protection from the exhaus t flow 12.
  • the width and depth of bend 24 may be constant or vary differently.
  • the outlet depth 106 and outlet width 1 03 may substantially match the width or diameter of the straight part 22.
  • a minimum center depth 1 18 represents a central depth of the bend 24 where it is the smallest because of the indentation 84.
  • This minimum center depth 1 1 8 is the depth of the bend 24 along the bend central plane 1 1 2 from the bend inner curve 78 to the maximum bend extension point 1 10.

Abstract

L'invention concerne un système de traitement postcombustion de gaz d'échappement de moteur comprenant un coude acheminant un écoulement de gaz d'échappement dans une direction courbe vers une partie rectiligne. Un gicleur est monté dans le coude pour introduire une pulvérisation d'un fluide ayant un axe de symétrie dans l'écoulement de gaz d'échappement. L'axe de symétrie croise l'écoulement de gaz d'échappement avançant dans la direction courbe au niveau d'un angle de croisement inférieur à 50 degrés.
