Hydrocarbon injector deflector assembly for diesel exhaust system

A hydrocarbon injector deflector assembly for a diesel exhaust system of a vehicle having an exhaust flow, the assembly comprising:

• an exhaust column;
• a hydrocarbon injector disposed to and in fluid communication with the exhaust column, the hydrocarbon injector configured to introduce hydrocarbons to be mixed with the exhaust flow;
• a mixer disposed within the exhaust column downstream from the hydrocarbon injector, the mixer configured to mix hydrocarbon and exhaust flow and distribute them uniformly;
• and
• a diesel particulate filter disposed downstream from the mixer, the diesel particulate filter being connect to and in fluid communication with the exhaust column;
• a hydrocarbon injector deflector comprising:
• a base plate disposed in the exhaust column between the hydrocarbon injector and the mixer, the base plate having a first end linearly extending to a second end to define a first side and a second side, the base plate being arcuately formed such that the first side extends arcuately to the second side, the base plate being disposed adjacent the hydrocarbon injector, the first end being disposed upstream relative to the second end;
• a frame connected to the second end of the base plate and extending therefrom at a first angle, the frame having an opening formed therethrough, the window defining an outer wall having an inner side of the frame;
• and
• a tab extending from the inner side of the frame at a second angle.

A vehicle having a diesel exhaust system with a hydrocarbon injector deflector assembly for exhaust flow, the vehicle comprising:

• a chassis;
• a body supported by the chassis, the body including a motor compartment and an occupant zone;
• and
• a diesel exhaust system comprising:
• an exhaust column;
• a hydrocarbon injector disposed to and in fluid communication with the exhaust column, the hydrocarbon injector configured to introduce hydrocarbons to be mixed with the exhaust flow;
• a mixer disposed within the exhaust column downstream from the hydrocarbon injector, the mixer configured to distribute exhaust flow;
• and
• a diesel oxidation catalyst and a diesel particulate filter disposed downstream from the mixer, the diesel oxidation catalyst and diesel particulate filter being connect to and in fluid communication with the exhaust column;
• a hydrocarbon injector deflector comprising:
• a base plate disposed in the exhaust column between the hydrocarbon injector and the mixer, the base plate having a first end linearly extending to a second end to define a first side and a second side, the base plate being arcuately formed such that the first side extends arcuately to the second side, the base plate being disposed adjacent the hydrocarbon injector, the first end being disposed upstream relative to the second end;
• a frame connected to the second end of the base plate and extending therefrom at a first angle, the frame having an opening formed therethrough, the window defining an outer wall having an inner side of the frame;
• and
• a tab extending from the inner side of the frame at a second angle.
