In the present work, in order to improve performance characteristics such as power output and reduce fuel consumption in spark ignition engines and engines used in the aerospace industry, combined gasoline fuels with dimethyl ether and iron oxide nano catalysts that can be synthesized at lower prices than other catalysts , Has been studied in a gasoline spark ignition engine. In order to achieve the steady state in the experimental stages, the temperature of the water and engine oil before each test of the EF7 spark ignition engine at engine speed of 2800 rpm is about 10 to 15 minutes to reach the various parts of the engine. The tests are carried out at full load conditions and engine speed rpm 2800 and between torques 0 to N.m 100. The output power and fuel consumption of the engine, with the combination of gasoline with 10% of the dimethyl ether, increased by 22.5% and 28.28% respectively, and in the case of gasoline in combination with 10% of dimethyl ethyl and 10ppm of iron oxide nano additive, lead to output power 19.44% increased and fuel consumption 19.5% reduced. in the case of gasoline in combination with 10% of dimethyl ether and 20ppm nano additive of iron oxide lead to output power 13.93% increased and fuel consumption 11.08% reduced, compared to the base fuel gasoline. emissions have also been reduced by combined fuel with iron oxide nano catalysts.
