Ducted fuel injection system alignment device

An alignment device for a ducted fuel injection system, the alignment device comprising:

• a mounting block removably attachable to a duct of the ducted fuel injection system, wherein the mounting block includes a passageway extending therethrough, wherein the passageway aligns with the duct when the mounting block is attached to the duct;
• a camera with a lens and/or an image relaying system attached thereto configured to capture an image viewing through the duct toward an outlet of a fuel injector, wherein a portion of the lens and/or image relaying system extends into the passageway;
• and
• a hollow cylinder removably insertable into an interior of the duct, wherein an outer diameter of the hollow cylinder is sized based on an inner diameter of the duct, wherein an inner diameter of the hollow cylinder is sized based on a dimension of the lens and/or image relaying system, wherein the hollow cylinder is configured to align the portion of the lens and/or image relaying system with a central axis of the duct,
• wherein the image captured by the camera is used to align a position of the outlet of the fuel injector with respect to a position of the duct.
