BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device for the transformation of internal combustion engines using liquid fuel, into gas, over-pressurised engines.
2. Discussion of the Background
At the present time, only two types of fuel feeding devices for automobile engines are known: carburettors, generally of the float type, and sequential projection injectors. The main drawbacks arising from the projection into the cylinders of liquid fuel pulvesed into more or less fine drops, in collaboration with a certain volume of air, are essentially an incomplete internal combustion of the air-fuel mixture in the cylinders, which causes a fairly rapid soiling of the cylinders, poor yield and increased environmental pollution through the unburned particles in the air-fuel mixture. The soiling of the cylinders rapidly destroys the lubrication features of the engine lubricant because of the particles and soot generated by the unburned fuel. This provokes the premature damaging of the piston rings and skirts of the engine, and that of the crankshaft bearings and the piston rods, in the case of high pressure feeding diesel engines. Very high pressure feeding requires the use of high accuracy pumps, and thus is very expensive, as well as a feeding circuit adapted to resist such pressures. The injection system is also very accurate and expensive and easily liable to go out of adjustment.
In order to overcome such drawbacks, car manufacturers have been researching mechanical, electrical or thermal means which involve, among other features, with a pre-chamber preceding the classical distributor. However, the improvement provided to engines, more generally petrol engines, cannot be carried out on the so called diesel engines, which are provided with high pressure injection devices at 150 bar. The tendency is to further increase the accuracy of the injection, in order to feed each cylinder with exactly the same amount of fuel. This, together with the fact that the means of control are becoming more sophisticated and expensive, causes an increase in the likelihood of breakdown. They have as a drawback the fact that they easily go out of order. Generally, the know devices need continual, expensive maintenance, which is rarely warranted by the users, but is by the professionals in the art, who are equipped with the appropriate tools.
It is to be noted that the problem of automobile pollution, mainly due to heavy fuel consumption, arising from the continuous growth of world-wide automotive park, has become a main concern in all developed countries, and so it will in all the developing countries, where the automotive park is rapidly being extended.
The problems which the invention seeks to overcome are the following: engines, specially the pollution generated by diesel engines in the so-called "heavy weighted" vehicles, but also in marine engines, electrical power generation engines, and so on, by removing the unburned particles,
SUMMARY OF THE INVENTION
The device according to the invention succeeds in the specified goals by providing a novel and simple means for the gasification, at the molecular level, of the air-fuel mixture in a premixing chamber and in a gasification chamber adapted to the intake of each cylinder of internal combustion engines.
It is devised to replace carburettors or injectors in any type of petrol engines and particularly to eliminate pressure feeding in diesel power engines which are the most pollutant, and amongst them, those with which heavy weighed vehicles are furnished, public works engines, marine engines, and so on. The disclosed gasification means transforms classical liquid fuel, internal combustion engines into gas engines.
The auto-ignition pressure inside diesel engines, of about 23 to 24 bar, is thus lowered so as to eliminate the auto-ignition which is needed in a fuel feeding under high pressure. The ignition is obtained by means of a high voltage, electronic ignition facility and the engine is over-pressurised by means of a compressor whic
