The system comprises a turbine (11) located within a housing (12) which is attached to the rear end of an alternator (3). The shaft of the alternator (3), which is driven by the fan belt from crank shaft of the internal combustion engine, is coupled to a gear (16) which in turn rotates a gear (31) fixed to the shaft (13) of the turbine (11). The turbine housing (12) has an air inlet (10) open to the atmosphere and an outlet (19) which connects to the combustion chambers of the engine.

Description

TURBO-CHARGING APPARATUS FOR INTERNAL COMBUSTION ENGINES
The present invention relates to motor vehicle internal combustion engines, and in particular, to a turbine which is used to increase the output power of the engine.
BACKGROUND ART
There are known methods of super charging internal combustion engines in which a turbine is usually driven from a shaft connected to the engine whereby the turbine pressur¬ izes the air input into the combustion chamber of the engine thereby increasing the power output for the given combustion ratio of the engine. The turbine is generally operated by a pulley taken off the crank shaft of the engine.
Another method of increasing the performance of an internal combustion engine is to use turbo charging. Using this method, the turbine is driven by the pressure of the expanding exhaust gases of the engine which in turn forces fresh air into the combustion chamber of the engine or, alternatively the exhaust gases can be reapplied to the engine so as to the unused fuel.
In the turbo charging of internal combustion engines, the extra power output is basically being generated by using the waste products of the engine.
OBJECT OF THE INVENTION
It is an object of the present invention to provide a turbine which is used to increase the power output of an internal combustion engine.
DISCLOSURE OF THE INVENTION
According to one aspect of the present invention there is disclosed a turbine system for use with an internal combustion engine of a motor vehicle, said system comprising a turbine which is driven by a sprocket drive connected to the shaft of an electrical alternator which is driven by a fan belt connected from the crank shaft of said engine, wherein said turbine is rotated at approximately six times that of the alternator shaft and said turbine compresses an air supply to be fed into said engine.
BRIEF DESCRIPTION OF THE DRAWINGS One embodiment of the present invention will now be described with reference to the drawings in which Fig. 1 is a perspective view of a turbine and alternator system of the preferred embodiment; and
Fig. 2 is an exploded view of the system of Fig. 1. BEST MODE OF CARRYING OUT THE INVENTION
The turbine system 1 of the preferred embodiment comprises a turbine 2 and an alternator 3. The alternator
3 has a shaft 4 on which the armature (not illustrated) is located. At one end 6 of the alternator 3 a pulley 7 is located, with a fan 5. The pulley 7 is bolted to the shaft
4 by a bolt 8.
The alternator 3 has a flange 21 with screwed holes 22 through which bolts (not illustrated) mount the alter¬ nator 3 into position adjacent the internal combustion engine (not illustrated) . The flange 21 is secured to the body 25 of the alternator 3 by four bolts 23 which extend through holes 24 in the alternator body 25.
At the other end 9 of the alternator 3 the turbine 2 is connected via the four bolts 24 which screw into screwed holes 26 located at the end of the turbine 2. The turbine 2 comprises an air inlet 10^ a turbine fan 11 which is locatable within a housing 12. The fan 11 has a shaft 13 which has a thread 30 with gears 31 at the end of the shaft 13 opposite the air inlet 10. Bearings 11 allow rotational movement of the shaft 13. A sprocket drive 16 is connected to a further shaft 17 which is aligned and coupled through a coupling 18 to the shaft 4 of the alternator 3.
The housing 12 in the turbine 2 has an air outlet 19 which is connectable to carbureter (not illustrated) or fuel injection system of an internal combustion engine.
The sprocket drive 16 has a ratio of approximately 6:1. This means that if the engine revs to 5,000 RPM, the turbine 2 will turn at 90,000 RPM.
In operation, the turbine system 1 operates such that the compressed air from the turbine 2 is fed into the combustion chamber of the engine (not illustrated) via the carbureter or fuel injection system. The advantages of the present invention include the fact that the turbine is operable off the alternator shaft and that the unit will not overheat as it is not operated off the exhaust gases of the engine.
The turbine system 1 of the preferred embodiment can be altered in order that it fits all makes of engines. The housing 12 has six different positions whereby the housing 12 can be rotated in order to have a configuration to fit different engines, such as diesel or normally aspirated.
It is also possible to restrict the top and bottom end performance (i.e. pressure at idle speed and maximum revolutions of engine) by changing the gear ratio of the sprocket drive and also by adjusting the size of the pulley 7 on the alternator 3 which is rotated by the fan belt of the engine.
If it is required to change the top end pressure or performance of the turbine it is possible to adapt the size or change the size of the inlet 10 of the turbine.
The sprocket drive 16 and gears 31 are lubricated by either using a splash feeder fed from a reservoir (not illustrated) or by using the engine oil from the sump of the engine.
INDUSTRIAL APPLICATION It has been found that in operation the turbo-charging system of the present invention can obtain 30% reduction in the amount of fuel that is required for running a motor vehicle which uses the turbine constantly. It has also been found that the production of carbon monoxide is greatly- reduced as the extra pressurized air injected into the combustion chamber assists the utilisation of all the fuel during the combustion cycle. Tests have shown that th_ polluting expellents of the engine are reduced by about 50%.
Due to the simplicity of the construction of the turbine system of the preffered embodiment it is therefore a simple and inexpensive system to provide better performance with better fuel economy for a standard engine of a motor vehicle. It is possible that the system can be installed by the non-skilled.
The foregoing describes only one embodiment of the present invention, and modifications obvious to those skilled in the art can be made thereto without departing - from the scope of the present invention.
For example, the turbine system does not have to be driven by the alternator shaft but can be operated by use of a hydraulically driven pump or by another pulley system not using the alternator fan belt and pulley.
