摘要： A method for deposit mitigation in a gaseous fuel injector that introduces a gaseous fuel through a gaseous fuel orifice directly into a combustion chamber of an internal combustion engine includes at least one of a) reducing the ago length of the gaseous fuel orifice by substantially between 10% to 50% of a previous length of a previous gaseous fuel orifice showing deposit accumulation above a predetermined threshold; b) providing the gaseous fuel orifice with an inwardly and substantially linearly tapering profile; c) determining deposit mitigation is needed; and performing at least one of the following deposit mitigation techniques i) increasing gaseous fuel injection pressure wherein deposit accumulation is reduced during fuel injection; and ii) decreasing gaseous fuel temperature wherein a rate of deposit accumulation is reduced; and d) injecting compressed air through the gaseous fuel orifice during shutdown of the internal combustion engine; whereby torque loss in the internal combustion engine due to deposit accumulation in the gaseous fuel orifice is reduced below a predetermined value.

摘要： A power generating assembly including an internal combustion engine and a combustion gas supply connected to the internal combustion engine in order to supply combustion gas. The combustion gas supply has an at least double-walled line at least in the region of the internal combustion engine, the line having an inner line volume for combustion gas and an outer line volume. The outer line volume is fluidically connected to an inert gas supply. The power generating assembly also includes a combustion gas pressure adjusting device that adjusts a combustion gas pressure in the inner line volume, and an inert gas pressure adjusting device that adjusts an inert gas pressure in the outer line volume. The combustion gas pressure adjusting device and the inert gas pressure adjusting device select the inert gas pressure and the combustion gas pressure such that the inert gas pressure is higher than the combustion gas pressure.

摘要： The system heats glycol water using steam generated by a boiler and heating LNG using the glycol water, thereby increasing efficiently the LNG to temperature required for an engine. In addition, the system senses LNG flowing to a glycol tank using a pressure sensor, etc. when the LNG flows to the glycol tank due to pressure difference between a fuel supplying line and a glycol circulation line generated according as a heat exchanger is broken down, and outputs the flowed LNG to the outside. As a result, the glycol circulation line may be returned to original state and stability of the system may be enhanced.

摘要： A fuel injector assembly is adapted to inject a compressed fuel into a combustion chamber of an internal combustion engine. The compressed fuel is stored in a fuel storage tank at a fuel storage pressure and delivered to the fuel injector assembly through a fuel supply line at a fuel supply pressure. The fuel supply pressure is lower than the fuel storage pressure. The fuel injector assembly includes a fuel injector and an adapter valve. The fuel injector injects the compressed gas fuel. The adapter valve is positioned between the fuel injector and the combustion chamber. The adapter valve allows the compressed gas fuel injected by the fuel injector to be discharged from an outlet of the adapter valve into the combustion chamber in an injection direction while preventing blowback gas entering the outlet from passing through the adapter valve in an ingress direction opposite the injection direction.

摘要： A method of controlling a fuel injector is provided. Engine speed is monitored. Engine torque output is monitored. It is determined if the engine speed is within one of a plurality of predefined engine speed ranges. It is determined if the engine torque output is within one of a plurality of predefined engine torque output ranges. One of a plurality of injector coking factors is assigned based on the determined predefined engine speed range and the determined predefined engine torque output range. A total injector coking factor is calculated based upon total operating time within each of the plurality of injector coking factors. A duration of a fuel injection is increased based upon the calculated total injector coking factor.
