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.

Abstract: Various methods and systems are provided for a drain system for an EGR system of an engine system. In one example, the drain system includes a connector fluidly coupled to each of an intake system, an exhaust system, and a fluid collector, where the connector is positioned vertically below an intake manifold of the intake system and an exhaust passage of the exhaust system and vertically above the fluid collector with respect to a surface on which an engine sits.

Abstract: A method and system for detecting fugitive fueling arising from a pressure-lubricated air inlet system component, such as a turbocharger, within an internal combustion engine includes monitoring lubricating oil pressure within at least one location within the lubrication circuit of the engine and comparing the monitored oil pressure with the failure range contained within a component failure template. If the monitored oil pressure lies within the failure range of the component failure template, remedial action will be taken to mitigate engine damage caused by oil entering engine cylinders from the failed component.
