Utilization of magnetic instrument is one effort to improve the performance and reduce exhaust emission produced by Otto engine. The experiments are done by varying the engine speed and variation of magnetic instrument mounting distance to the inlet valve when entering the combustion chamber. A magnetic instrument is installed in the intake manifold, before heading into the combustion chamber. The experimental results show that it is found that there is an increase in thermal efficiency and decreasing of fuel consumption when the engine uses 2500 gauss magnetic instrument ranging from 5.99 to 22.02%. The emissions of exhaust gas produced also reduced for CO and HC levels about 6-20%.
