Multi fuel co-injection system for internal combustion and turbine engines

摘要

An improved multi-fuel supply and co-injection system and method for powering internal combustion and turbine engines, whereby various combinations of fuels, both liquid and gaseous, may be mixed together and fed into the system, under the real-time control of a microprocessor responding to a variety of sensors and acting on a variety of control devices, all working together in a manner designed to enhance the utilization of the thermal content of the various fuels, and in particular to enhance the combustion efficiency and increase the power output while decreasing the consumption of fuel, calculated both by quantity and by cost and whereby the liquid fuel lubricates the moving parts of the injection system.

主权项

1. A system for multi-fuel injection within an engine from at least two fuel supplies, the engine having an injector including an injector pump, the improvement comprising:
a manifold in fluid communication with and downstream of the at least two fuel supplies wherein fuels from the at least two fuel supplies are mixed to produce a fuel mixture as controlled by a combination flow sensor and a control valve located in-line between each fuel supply and the manifold; and a high-pressure positive displacement pump in fluid communication with and downstream of the manifold and in-line between the manifold and the engine, whereby the fuel mixture is brought to higher pressure before being injected by the injector; wherein: a first fuel is in a liquid state as supplied by a first fuel supply and delivered to the manifold; and a second fuel is in a gaseous state as supplied by a second fuel supply and delivered to the manifold, whereby the fuel mixture is a liquid-gaseous fuel mixture and the positive displacement pump pressurizes the liquid-gaseous fuel mixture prior to injection.
