Ducted fuel injection system alignment device

DWPI Title: Device for aligning ducts in ducted fuel injection system with respect to common fuel injector of direct injection engine, has imaging device capturing image viewing through duct toward outlet of fuel injector, and centering structure aligning portion of imaging device with central axis of duct
Abstract: An alignment device for a ducted fuel injection system comprising a mounting block removably attachable to a duct of the ducted fuel injection system. The mounting block can include a passageway extending therethrough. The passageway can align with the duct when the mounting block is attached to the duct. The alignment device further comprises an imaging device configured to capture an image viewing through the duct toward an outlet of a fuel injector. A portion of the imaging device can extend in the passageway. The alignment device additionally comprises a centering structure configured to align a portion of the imaging device with a central axis of the duct. The image captured by the imaging device can be configured for use aligning a position of an outlet of a fuel injector with respect to a position of the duct.
Use: Device for aligning ducts in a ducted fuel injection system with respect to a common fuel injector of a direct injection engine.
Advantage: The device enables simultaneous, cost-effective, dramatic attenuation of both soot through ducted fuel injection and nitrogen oxide through dilution to break long-standing soot/nitrogen oxide trade-off for diesel engines. The device is fully compatible with current commercial diesel fuel and synergistic with oxygenated renewable fuels, so that larger reductions of soot and net carbon emissions can be achieved when duct-fuel injection and renewable fuels are used together, and cost of the system can be reduced. The device aligns a portion of the imaging device with a central axis of the duct, so that the image captured by the camera can be configured for use aligning a position of an outlet of a fuel injector with respect to the position of a position
Novelty: The device (100) has a mounting block (104) removably attachable to a duct (118) of a ducted fuel injection system (102) and including a passageway (124). The passageway aligns with the duct when the mounting block is attached to the duct. An imaging device (106) captures an image viewing through the duct toward an outlet of a fuel injector (116). A portion of the imaging device extends into the passageway. A centering structure (108) aligns the portion of the imaging device with a central axis of the duct, where the image captured by the imaging device is used to align a position of the outlet of the fuel injector with respect to a position of the duct.
