| Abstract | ||
| The present work deals with the effect of the magnetic field on the performance of (spark ignition engine). Thermal efficiency, brake specific fuel consumption (bsfc) and exhaust emissions were measured for Iraqi gasoline which has octane number of (83). The fuel was subjected to a magnetic field of (1000 and 2000 Gauss), respectively. The magnetic field was placed on fuel supply line to magnetize the fuel before admitting it to the carburetor. Mercedis Benz SI engine, 4 strokes, and 4 cylinders were used in this study under engine speed ranging between (2000 to 3500 rpm) at maximum load. A reduction in fuel consumption up to (2.19%) and (5.488%), brake thermal efficiency rose by about (4.7%) and (13.5%), for one and two magnets, respectively. The exhaust gas emissions showed a reduction in CO nearly by (3.7%) and (6.9%), CO2 up to (3.43%) and (9.2%). However the exhaust temperature increased up to (1.7%) and (3.65%) for the two magnets values, respectively. | ||
