    Abstract: A dual fuel engine utilizes a compression ignited pilot injection of liquid diesel fuel to ignite a mixture of gaseous fuel and air in each engine cylinder. The gaseous fuel is injected at a relatively low pressure directly into the engine cylinder from a fuel injector. The liquid diesel fuel is injected directly into the engine cylinder from the same fuel injector. In-cylinder dynamic gas blending during the compression stroke can reduce potential hydrocarbon slip that could occur when unburned fuel resides in crevice volumes within the engine cylinder.

    Abstract: A system includes a main engine operating on gaseous fuel from a tank. An auxiliary engine operates using gaseous fuel vented from the tank. A first exhaust passage receives a first stream of exhaust gas from the main engine. A second exhaust passage receives exhaust gas from the auxiliary engine, which passes through an ammonia-producing catalyst. A third exhaust passage is fluidly connected to the first and second exhaust passages and routes exhaust gas through a NOx reducing catalyst. The system operates such that a mass flow of ammonia generated by the ammonia-producing catalyst substantially matches a total mass flow of NOx gas in the third exhaust passage that is treated within the ammonia-producing catalyst.

    Abstract: A fuel injector includes an injector body and a valve stack within the injector body that includes a valve seat plate. The valve seat plate includes a pressure control passage for controlling fuel injection, and a valve seat positioned fluidly between the pressure control passage and a low-pressure drain. The valve seat plate includes a pressure-limiting annular groove that extends circumferentially around the valve seat and axially inward from a side of the valve seat plate where the valve seat is located. The groove enables deformation in response to pressure differences across the valve seat plate in a manner that limits stress concentrations.
