Wykorzystanie pola magnetycznego do wzbogacenia powietrza tlenem

Artykuł przedstawia ideę oraz badanie wstępne dotyczące wzbogacania powietrza w tlen z wykorzystaniem pola magnetycznego. Powietrze jest mieszaniną gazów, poszczególne gazy mają różną podatność magnetyczną. Różne właściwości magnetyczne gazów, dają możliwość rozdzielenia ich przy użyciu silnego pola i dużego gradientu pola magnetycznego. Silną niejednorodność pola magnetycznego można wytworzyć za pomocą membran o odpowiednich właściwościach. Efektem przepływu powietrza przez membranę może być powietrze wzbogacone w tlen lub też czysty tlen.

The article presents the idea and preliminary investigations on air enrichment with oxygen using a magnetic field. Air is a mixture of gases, the different gases have different magnetic susceptibility. Due to different magnetic properties of gases, the possibility is rendered to separate them by using strong magnetic fields and high magnetic gradient field. The strong heterogeneity of the magnetic field can be prepared using membranes with appropriate properties. The effect of an air flow through the membrane may be the oxygen-enriched air or the pure oxygen.

The works carried out on combustion engine improvement are focused on increase of their efficiency, effective power, mass decrease, limiting of fuel consumption and reduction of toxicity and quantity of unwanted components of exhaust gases. The aim of these attempts is to satisfy the more and more rigorous regulations concerning environment protection. The basic method of power increase of engines concurrent with improvement of their characteristics lies in increase of a charge dose supplied to the cylinder. There are some ways to achieve this aim. One of this methods lies in increase of the coefficient of filling by growth of air density in the cylinder, another one is application of alternative fuels containing bigger amounts of oxygen compounds. There is still another method of increased oxygen dose as application of nitrogen suboxide N2O. The method up till now not used consists is supply of fuel air mixture enriched in oxygen. This permits to increase the engine power at concurrent decrease in emission of toxic components in exhaust gases. An evident positive of this method is the possibility of its application in automobile vehicles without lowering their traditional properties. Realization of this problem requires application of one of the two technologies of atmospheric oxygen separation. The first of these methods is oxygen separation by use of molecular sieves. This method is known as PSA method (Pressure Swing Adsorption). The other one makes use of oxygen separation from air by mines of membrane processes. There exists also a number of modifications of methods that base on molecular sieves – one of them being the ATF method ( Advanced Technology Fractionator) patented in the USA in 2004. All these methods are used to obtain oxygen applied in industrial processes. Apparatus used for medical purpose as well as the system know as OBOGS (On-Board Oxygen Generating) applied among others in aircraft F-16 for supply of pilot’s oxygen mask are an exception. In connection with the elaborated solution a patent application was made by the chief of the project consisting in adaptation of the ATF method to traction conditions. The carried investigations aim at checking the possibilities of engine power increase limit and influence of this increase on its mechanical and heat resistance and on exhaust gases toxicity. The results of these investigations will influence economical profitability of application of this method in the feeding system of automobile vehicles.
