Abstract: A mixing device for introducing gaseous fuel into an intake airflow of an engine, the mixing device including an inlet, an outlet, an intake passage extending between the inlet and the outlet, an annular channel, and a plurality of fuel supply manifolds, each coupled to a main gaseous fuel inlet of the mixing device, and a separate plurality of gaseous fuel injectors coupled to each one of the plurality of fuel supply manifolds to receive gaseous fuel from the corresponding fuel supply manifold. The annular channel is configured to receive gaseous fuel injected from all of the separate pluralities of gaseous fuel injectors. The mixing device includes a diffuser, the diffuser arranged to receive gaseous fuel from the annular channel and operable to diffuse gaseous fuel from the annular channel into the intake airflow.

Abstract: A mixing device for introducing gaseous fuel and recirculated exhaust gas into an intake passage of an engine, the mixing device including a body, an annular channel, the body defining a fuel inlet opening, and a plurality of gaseous fuel injectors fluidly coupled to the fuel inlet opening such that gaseous fuel from the plurality of gaseous fuel injectors is conveyed into the annular channel through the fuel inlet opening. The mixing device further includes a diffuser at a position of the annular channel to diffuse gaseous fuel from the annular channel into the intake airflow in the intake passage, an exhaust gas recirculation (EGR) inlet opening defined by the body and in fluid communication with the intake passage, and an exhaust gas recirculation supply pipe coupled to the EGR inlet opening and configured to direct recirculated exhaust gas from the engine into the intake passage.

Abstract: A method for equipping an engine with a mixing device for introducing gaseous fuel into an intake passage of the engine comprising the steps of providing a body through which the intake passage extends, wherein an annular channel encircles the intake passage, providing a fuel inlet manifold with injector receiving ports, each injector receiving port configured to receive a discharge end of a fuel injector, with each injector receiving port in fluid communication with the annular channel, and providing a fuel supply manifold including fuel injector ports, wherein each fuel injector port is configured to receive an upstream end of a fuel injector. The method further includes blocking at least one injector receiving port such that fluid communication through the injector receiving port is prevented, removably coupling fuel injectors between the fuel supply manifold and the unblocked injector receiving ports, and providing the mixing device to the engine.

Abstract: A novel method and system for an LCR engine, herein referred to as a Dynamic Intelligent Routing Engine (DIRE) is disclosed that optimizes in real time the routing of data on a communication network. The method and system includes novel hardware architecture and software where routing queries from telecommunication switching equipment is sent to the DIRE. The DIRE responds to the queries by providing an optimized list of termination vendors. The DIRE provides real time or near real time solutions by addressing issues pertaining to mixed and fixed costs routes, control margins, weighted routing parameters, quality routing and other selected information that may affect routing costs.
