Abstract
A method and arrangement of supplying a supplementary fuel (8) to a compression ignition internal combustion engine wherein an air supply (3) to the engine is first caused to pass through a natural vortex creator (1), and a supply of supplementary fuel (8) to the engine is supplied into a low pressure area the natural vortex (1) which provides a substantially constant ratio of supplementary fuel to main fuel through varying load conditions.
Claims7
A method of supplying a fuel supply to a compression ignition internal combustion engine which includes having an air supply to the engine first caused to pass through a natural vortex creator, and effecting a supply of supplementary fuel to the engine by introducing supplementary fuel into a low pressure area within a central area of any natural vortex being created by the vortex creator.
A compression ignition engine including in its supply a natural vortex creator, a conduit connecting an outlet of the vortex creator with an air inlet of the engine, a conduit connecting a source of supplementary fuel with the vortex creator so as to have an outlet of the said conduit communicating with a low pressure center of a vortex.
A compression ignition internal combustion engine including at least one piston within a cylinder, a main fuel injector to effect injection of fuel into each respective cylinder, means to effect a change in quantity of main fuel being injected into the cylinder in response to change in load applied to the engine, a conduit connecting an outlet of a natural vortex creator with an air inlet of the cylinder of the engine, a conduit connecting a source of supplementary fuel with the vortex creator with its outlet communicating with a low pressure center of the vortex creator.
A compression ignition internal combustion engine including at least one piston within a cylinder, a main fuel injector to effect injection of fuel into each respective cylinder, means to effect a change in quantity of main fuel being injected into the cylinder in response to change in load applied to the engine, a conduit connecting an outlet of a natural vortex creator with an air inlet of the cylinder of the engine, a conduit connecting a source of supplementary fuel in gaseous form with the vortex creator with its outlet communicating with a low pressure center of the vortex creator, means connecting a source of the supplementary fuel as a liquid to a low pressure area of a second natural vortex creator which is arranged to effect a natrual vortex with air being drawn through it by the cylinder, a conduit connecting an outlet of the second natural vortex creator to a low pressure area of the first said natural vortex creator.
