Abstract

Steam produced in a coil in the engine exhaust manifold or by electrical heating is supplied to the carburettor intake or the intake manifold. The steam quantity may be metered in accordance with engine load or speed and the temperature may be controlled in response to engine operating conditions.

Description

SPECIFICATION Method and Apparatus for Promoting Combustion in Internal Combustion Engines The present invention relates to a method and apparatus for promoting combustion in an internal combustion engine and, thereby, reducing fuel consumption.
The present invention is based on the idea of vapourizing a liquid (other than fuel) and introducing the vapour into the combustion chambers of the engine along with the fuel/air mixture. The liquid is one giving rise to a vapour capable of promoting combustion of the fuel and it may be introduced into the engine, for instance, by introducing the vapour directly into the intake manifold or, in the case where a carburettor is used, into the air intake thereof.
The liquid may be vapourized by heat generated by the engine, for instance, by passing the liquid through a conduit housed within the exhaust manifold of the engine; and such a conduit may be in the form of a coiled tube.
Alternatively, the liquid may be electrically heated, e.g. from the electrical system of the vehicle. The liquid from which the vapour is to be formed may be contained in a reservoir housed in the engine compartment.
The liquid employed may be water, the water being heated to form superheated steam, which is then introduced into the engine.
The amount of vapour fed to the engine may be metered to relate it to the speed and load of the engine; and the temperature of the vapour may likewise be controlled to the optimum for any given operating conditions of the engine.
In an embodiment of the invention, water taken from a container housed within the engine compartment of a petrol driven car employing a carburettor, was ducted to a coiled tube housed within the exhaust manifold of the engine. The water passed into the coiled tube was converted to superheated steam after starting of the engine, and the steam was then ducted either to the air intake of the carburettor or to the intake manifold; the latter being bored to take the end portion of tube by which the steam was ducted from the coiled tube.
It was found on running the vehicle over measured distances and using measured amounts of fuel, that the petrol consumption was some 17% less than it was without the introduction of the steam.
Claims
1. A method of promoting combustion of fuel in an internal combustion engine which comprises vapourizing a liquid (other than fuel) and mixing the vapourperse with the fuel and/or air to be delivered to the combustion chamber or chambers of the engine; the liquid being one whose vapour is capable of promoting combustion of the fuel.

5. A method according to claim 1 or 2, wherein the liquid is electrically heated.
6. A method according to any of the preceding claims, wherein mixing of the liquid vapour with the fuel and/or air is effected by passing the vapour into the inlet manifold of the engine.
7. A method according to any of the preceding claims 1 to 5, for use with an engine comprising a carburettor, wherein-mixing of the liquid vapour with the fuel and/or air is effected by passing the vapour into the carburettor air intake.
8. A method according to any of the preceding claims, wherein the amount of vapour mixed with the fuel and/or air, is metered to relate it to the speed or load of the engine.
9. A method according to any of the preceding claims, wherein the temperature of the vapour is controlled to the optimum for any given operating conditions of the engine.
10. A method according to claim 1, substantially as hereinbefore exemplified.

12. An internal combustion engine according to claim 1 comprising means for storing the liquid, means for delivering it to a heating device to vapourize the liquid and means for feeding the vapour to a location at which it mixes with fuel and/or air.
1 3. An internal combustion engine according to claim 12, wherein said heating device is the exhaust manifold of the engine, and a tube therein receiving the liquid from said delivering means so that the liquid is vapourized in tube by the heat of the exhaust gases; the tube connecting with said feeding means.
14. An internal combustion engine according to claim 12 or 13, wherein said location is the interior of the inlet manifold.
1 5. An internal combustion according to claims 12 or 1 3 employing a carburettor, wherein said location is the air intake of the carburettor.

SPECIFICATION Method and Apparatus for Promoting Combustion in Internal Combustion Engines The present invention relates to a method and apparatus for promoting combustion in an internal combustion engine and, thereby, reducing fuel consumption. The present invention is based on the idea of vapourizing a liquid (other than fuel) and introducing the vapour into the combustion chambers of the engine along with the fuel/air mixture. The liquid is one giving rise to a vapour capable of promoting combustion of the fuel and it may be introduced into the engine, for instance, by introducing the vapour directly into the intake manifold or, in the case where a carburettor is used, into the air intake thereof. The liquid may be vapourized by heat generated by the engine, for instance, by passing the liquid through a conduit housed within the exhaust manifold of the engine; and such a conduit may be in the form of a coiled tube. Alternatively, the liquid may be electrically heated, e.g. from the electrical system of the vehicle. The liquid from which the vapour is to be formed may be contained in a reservoir housed in the engine compartment. The liquid employed may be water, the water being heated to form superheated steam, which is then introduced into the engine. The amount of vapour fed to the engine may be metered to relate it to the speed and load of the engine; and the temperature of the vapour may likewise be controlled to the optimum for any given operating conditions of the engine. In an embodiment of the invention, water taken from a container housed within the engine compartment of a petrol driven car employing a carburettor, was ducted to a coiled tube housed within the exhaust manifold of the engine. The water passed into the coiled tube was converted to superheated steam after starting of the engine, and the steam was then ducted either to the air intake of the carburettor or to the intake manifold; the latter being bored to take the end portion of tube by which the steam was ducted from the coiled tube. It was found on running the vehicle over measured distances and using measured amounts of fuel, that the petrol consumption was some 17% less than it was without the introduction of the steam. Claims
