Abstract

An alignment system includes an optical sensor device that may be inserted into a passage of a body that is located between a fuel injector and a combustion chamber of an engine cylinder. The body is shaped to transmit fuel ejected from a spray hole in a fuel injector into the combustion chamber of the engine cylinder. The system also includes a controller that may examine output of the optical sensor device and determine whether the passage of the body is aligned with the spray hole of the fuel injector based on the output from the optical sensor device. The controller may change a position of one or more of the body or the fuel injector responsive to determining that the passage of the body is not aligned with the spray hole of the fuel injector.
