University, Jhunjhunu, Rajasthan (India) 2D. P. Bhosale College, Koregaon, M. S. (India) Abstract窶年umber of experiments in which influence of magnetic field with 1000 Gauss to 9000 Gauss intensity on working of Internal Combustion engine and exhaust emission is studied are considered for analysis. For this analytical study the experiments performed with both diesel and petrol engine are considered. Performance study of engine includes reduction in fuel consumption while the exhaust emission study includes reduction in CO, HC and other pollutants. The results show significant reduction in fuel consumption. Key words: Influence, Gauss, C. I. Engine, S. I. Engine, Analytical Study, Fuel Consumption I. INTRODUCTION Due to increase in number of vehicles over the years, the pollutants from exhaust are affecting environment badly. When fuel petrol or diesel burns in the combustion chamber, many polluting gases and particles are discharged in the environment. The discharge includes carbon monoxide, hydrocarbons and oxides of nitrogen, carbon dioxide and fine particles. These components in exhaust emission can penetrate into the human respiratory tract and cause respiratory infections and diseases like lung cancer and some cardiovascular diseases. The Government has introduced strict policy to decrease pollution from motor vehicles by improving engine and fuel formulation. Although technology improvements have reduced vehicle emissions there is still cause for concern because the number of vehicles on road continues to increase, urban development has increased the demand for vehicles and vehicles are main contributor to greenhouse gases. Along with the problem of environmental pollution the increased number of vehicles is creating the problem of fuel consumption. The increased number of vehicles is consuming stocks of fuel very rapidly. Hence it is the need of the day to reduce consumption of fuel and reduce the environmental pollution by reducing pollutants from exhaust emission of vehicles. Use of magnetic field for treatment of fuel before its combustion is the wonderful way to reduce both exhaust emission and fuel consumption. Liquid fuels such as petrol and diesel used for internal combustion engine do combust when they are vaporized and mixed with air [1].But due to the stable structure of fuel sufficient air cant mix with it. Hence incomplete combustion of fuel takes place. As a result fuel consumption of engine increases so also hydrocarbons present in the fuel are not burnt properly and come out through exhaust gases. This increases the pollution of environment. Theoretically the exhaust of engine should contain carbon dioxide, water vapor and nitrogen from air. But practically the exhaust of engine contains carbon monoxide, hydrocarbons, oxides of nitrogen and carbon dioxide. Practically fuel is never completely combusted. Therefore incompletely oxidized carbon in the form of HC and CO is deposited on the walls of combustion chamber.
Hydrocarbon fuel molecules treated with magnetic field tend to de-cluster, creating smaller particles leading to better combustion [1]. Magnetic fuel treatment works on the principle of interaction of magnetic field with fuel molecules to increase mixing of oxygen with fuel [1]. Liquid fuel consists of mixture of chemical compounds of carbon and hydrogen atoms in the form of a definite structure. Highly stable structure of fuel does not allow oxygen atoms to penetrate into the interior during air-fuel mixing process. Therefore incomplete combustion of fuel takes place. [2]. Hydrogen occurs in two isomeric forms Para and Ortho. In the Para form spin state of one atom relative to other is in opposite direction, while in the Ortho form spin state of one atom relative to other is in the same direction. Normally the fuel occurs in Para form but magnetic treatment of fuel changes it into ortho form. [3].When a strong magnetic is applied to fuel, hydrocarbon change their orientation and it changes from Para form to Ortho form [1]. In Ortho form considerable reduction in inter-molecular forces takes place causing increase in space between hydrogen. Due to the magnetic treatment of fuel interaction of fuel with oxygen increases and there is complete combustion of fuel in the chamber [4].
Fig. 1: Schematic view of Para and Ortho states of Hydrogen interacting with oxygen [4] Magnetic treatment of fuel tends hydrocarbon molecules to de-cluster giving increased surface for fueloxygen reaction leading to improved combustion. Thus when fuel is magnetized bonding between hydrocarbon and oxygen becomes stronger which gives rise to proper burning of fuel-air mixture in the combustion chamber and engine power gets increased. Therefore fuel consumption of engine gets reduced and emission of carbon particles, carbon monoxide and hydrocarbons and other pollutants also gets reduced. [1]. II. INFLUENCE OF MAGNETIC FIELD ON FUEL CONSUMPTION Effect of magnetic field on fuel consumption has been proved by number of experiments involving different fuels such as gasoline and diesel, different engines such as spark ignition and compression ignition, different magnets such as Ferrite based and Neodymium-Iron-Boron based magnets with different field intensities. A. R. A. Habbo et al [5] found reduction in fuel consumption of petrol by 12.8 % with a magnetic field intensity 1000 G and reduction of 21.3 % with a magnetic field of intensity 2000 G for single
