Abstract

Apparatus for adding an air-liquid mixture to the air or fuel-air charge for an internal combustion engine comprising a conduit (5) open to atmosphere at one end and connected to the engine intake at the other end such that vacuum in the intake manifold (6) causes an air stream to flow through the conduit (5). An adjustable valve (3) meters a flow of liquid from a reservoir (1) to an outlet in the conduit such that the air flow past the outlet causes the issuing liquid to break up and mix with the air stream. A valve (4) responsive to manifold vacuum is arranged in the conduit (5) to regulate the flow of air-liquid mixture to the engine intake such that the flow is increased with increasing engine load.

Description

AIR FUEL INJECTION DEVICE
A unit for adding a controlled and variable quantity of water and air to the inlet manifold of an internal combustion engine in order to reduce consumption of the main fuel used to power the motor whether such fuel be petrol, diesel oil, gas or other.
This unit can also be used to add to the motor a controlled quantity of an alternative fuel, added in conjunction with, or instead of, water, together with air, In such a case the unit is performing the function of a secondary carbur ettor,
The system comprises a water bag (ref, fig. (1) on diagram) or joined water bags, connected by a narrow" apperture pipe (2) to an adjustable valve (3), which allows regulation of the flow of water, or other fuel, to enable fine tuning to suit a particular size or type of motor or climatic conditions. This valve (3) also allows entry of air into the system in such a way that it causes the water to break down into fine particles.
This valve is connected to a self-ad usting metering device ( ) which automatically regulates the flow of water air mist to the motor. This automatic metering valve which is connected by a pipe (5) to any existing vacuum line entering at or near the centre of the inlet manifold (6) (for example the sump scavenger vacuum line or the power brake vacuum line) or directly to the inlet manifold, allows the water air mixture to be sucked into the inlet manifold in the desired quantities.
On entering the inlet manifold, the water is broken- down even further into a fog like mist, which has the effect of leaning the main fuel air mixture. The automatic metering valve is operated by vacuum through a pipe (7) connected to the vacuum line (8) running between the carbur ettor and the automatic advance and retard mechanism (9). In the case of a diesel engine the vacuum to operate the valve is obtained from any suitable source connected at or near the centre of the inlet manifold.
This automatic metering valve is designed so that, in the case of a motor employing a carbur ettor system,, when there is no vacuum applied to the diaphragm control (10) the valve (11)" closes, thus allowing no water air mixture to enter the inlet manifold. As the work load on the motor increases so the vacuum increases and the valve opens to allow water air mist to be sucked through the connecting pipe into the inlet manifold.
In the case of motors which do not use a carbur ettor type system the metering valve operates in reverse so that as the vacuum increases the valve closes giving the same result of allowing most water air mixture to enter the inlet manifold when there Is maximum load on the motor.

Claims

The Claims defining the invention are as follows:
1. An air fuel injection device for an internal combustion engine comprising a valve body, an inlet in said body to allow the intake of air and a secondary fuel supplied to the inlet from a storage container, an outlet from said body connected to the inlet manifold of the engine and a valve interposed between said inlet and outlet which opens when the engine is under load.
