PERFORMANCE OF SPARK IGNITION ENGINE UNDER THE INFLUENCE OF MAGNETIC FIELD

The present study investigates the effect of magnetic field on the performance of Single Cylinder Four Stroke Spark Ignition engine. The study concentrates on the effect of magnetic field the engine performance parameters such as fuel consumption, break thermal efficiency and exhaust emissions and on fuel properties like density and calorific value. The magnetic field is applied along the fuel line immediately beforecarburetor. The magnetic field is applied with the help of strong permanent magnets of strength 5000 gauss. The experiments are conducted at different engine loading conditions. The exhaust gas emissions such as CO, CO2, HC and NOX are measured by using an exhaust gas analyser. With the application of magnetic field the percentage reduction in fuel consumption is about 12 %, the percentage reduction in HC and CO is about27% and 11 % respectively. The NOx level in engine increases with the application of magnetic field. The percentage increase in NOx is about 19%. The effect of magnetic field on percentage increase of CO2 emissions from SI engine is about 7 %.
