This invention relates to a novel device for compressing and injecting gaseous fuel from a variable pressure gaseous fuel supply into a fuel receiving apparatus. More particularly, this invention relates to an intensifier-injector which compresses and injects gaseous fuel from a variable pressure source into the cylinder of a positive displacement engine. An intensifier-injector for gaseous fuels in internal combustion engines comprising means which utilizes the compressed gas from the chamber of the internal combustion engine or compressed fluid or gas from an external compressor to drive an intensifier means which raises the pressure of fuel gas supplied to the internal combustion engine for rapid late-cycle injection into the cylinder of the internal combustion engine.
A method of supply gaseous fuel directly into a combustion chamber of an internal combustion engine which comprises utilizing mechanical means to drive a pressure intensifier means which compresses the gaseous fuel to an injection pressure which is sufficient to exceed a pressure in the combustion chamber, thereby enabling the gaseous fuel to be rapidly injected into the combustion chamber, wherein a single injector is used for injecting fuel gas and liquid pilot fuel into the combustion chamber and wherein the injection of the fuel gas is conducted at a sufficiently high velocity to atomize the liquid pilot fuel injected with the fuel gas.
An intensifier-injector for fuel gas and entrained liquid pilot fuel used in combination with an internal combustion engine having a cylinder chamber, which intensifier-injector comprises:
An apparatus for transporting, controlling, mixing and introducing a liquid pilot fuel and a gaseous principal fuel into a combustion chamber of an internal combustion engine comprising means for atomizing the liquid pilot fuel by gas-blast atomization thereof by the gaseous principal fuel.
