Abstract: A hydrocarbon injector deflector for a diesel exhaust system includes a base plate having a first end linearly extending to a second end to define a first side and a second side. The base plate is arcuately formed such that the first side extends arcuately to the second side. The first end is disposed upstream of the exhaust system relative to the second end. The hydrocarbon deflector further includes a frame connected to the second end of the base plate and extends therefrom at a first angle. The frame has an opening formed through the frame. The opening defines an outer wall having an inner side of the frame. The deflector further includes a tab extending from the inner side at a second angle.
