Abstract
Abstract The aim of this study is to investigate the effect of the magnetized fuel on the perfor-mance of spark ignition engine. The engine performance was observed by examining the engine brake power (BP) , thermal efficiency , specific fuel consumption (SFC) and exhaust emissions .The fuel is subjected to a magnetic field which is placed to fuel supply line to magnetize the fuel before admitted to the engine cylinder. Two types of magnetic coils were adopted in this study, the first one with 1000 Gauss and the second with 2000 Gauss. Experimental tests were conducted at a speed of 2000 rpm , compression ratio 8 , wide open throttle (WOT) and ignition timing was set between 50 and 300 BTDC . The results show a significant improvements in engine performance, the thermal efficiency and engine power increased by (4 %) and (3.3 %) respectively when a magnetic coil of 1000 Gauss is used, and a reduction in the specific fuel consumption by (12.8 %) was achieved. However, when the magnetic coil of 2000 Gauss is used the brake power is increased nearly by (16.4 %) , thermal efficiency showed an improvement nearly by (7.6 %) , while the specific fuel consumption is decreased by (21.3 %) with respect with no magnetic field case . The exhaust gas emissions show a reduction nearly by (80 %) of CO and by (44 %) of HC when the magnetic coil of 1000 Gauss is used. A further reduction nearly by (90 %) of CO and by (58 %) of HC is obtained when the magnetic coil of 2000 Gauss is used .
