An injection/mixing device for improving the mixing of fuel and air in a petrol driven internal combustion engine. The device is fitted in the engine inlet manifold close to the fuel inlet from a carburettor or fuel injector and uses a vortex generator. The vortex generator is in the form of an array of lenticular, conical or deltoid disks located in the fuel/air flow and which serve to disperse the impinging fuel droplets and mix the fuel and air. The effect of the device is preferably enhanced by allowing the vortex generator to rotate or spin about its axis. This rotation is achieved by means of a turbine associated with the disks or by means of an external motor. The device may also be connected to a vacuum relief valve to attenuate the level of the depression in the intake manifold under certain conditions. The vacuum relief valve may be integral or separate from the device.
A device for mixing combustion gases in an internal combustion engine having an intake manifold with a flow axis comprising a vortex generator disposed in the intake manifold, said vortex generator comprising a circular disk having a disk axis and a generally aerofoil shape in a chordwise cross-section parallel to the disk axis, said disk being disposed in the intake manifold such that the disk axis is substantially perpendicular to the flow axis and to the flow of combustion gases over the disk.
A device for mixing combustion gases in an internal combustion engine having an intake manifold with a flow axis comprising a vortex generator disposed in the intake manifold, said vortex generator comprising a solid disk having a circular periphery and a disk axis, said disk comprising a truncated conical disk having an aerofoil shape in a chordwise cross-section and being disposed in the intake manifold such that the disk axis is substantially normal to the flow axis.
A device for mixing combustion gases in an internal combustion engine having an intake manifold with a flow axis comprising a vortex generator disposed in the intake manifold, said vortex generator comprising a solid disk having a circular periphery and a disk axis, said disk comprising an equi-convex lens, a bi-convex concave/convex lens and being disposed in the intake manifold such that the disk axis is substantially normal to the flow axis.
A device for mixing combustion gases in an internal combustion engine having an intake manifold with a flow axis comprising a vortex generator disposed in the intake manifold, said vortex generator comprising a solid disk having a circular periphery and a disk axis and being disposed in the intake manifold such that the disk axis is substantially normal to the flow axis, said intake manifold having a sidewall, said disk being mounted on a shaft extending through the sidewall of the intake manifold, said shaft being rotatably supported on said intake manifold and means connected to said shaft for rotating the same.
