Effect of MHD Principles on the Performance of a 4-Stroke Petrol Engine

An experimental study of the effect of Magnetic Fluid Conditioner on the performance of Four Stroke Petrol Engine was conducted. A 4 cylinder, 4 stroke automotive petrol engine made by premier automobile was used. Experimental results obtained from the engine fitted with magnetic fluid conditioner were compared with the same engine without using magnetic fluid conditioner. It is observed that the abovementioned engine with magnetic fluid conditioner produces reduced percentage of CO to an extent of 16.87% whereas HC is reduced to an extent of 46.08%, Brake Specific Fuel Consumption (B.S.F.C.) is reduced to an extent of 3%, and the Brake Thermal efficiency increases to an extent of 3.5%. It has been also found that, the magnetic fluid conditioning system has caused an increase of % of CO in the exhaust fumes immediately after the installation of it, and after a period of 40 hrs. running the CO(%) has come down. The amount of HC i.e. the unburnt fuel has been reduced subsequently which indicates an improvement of the combustion efficiency. Similarly, Brake Thermal Efficiency increases and Brake specific fuel consumption decreases. It is therefore concluded that judicious application of the magnetic fluid conditioner to petrol engine could be an useful means for improving engine performance and fuel economy and also for ‘abating’ pollution'.
