Technology based on ZnO nanomaterials in vehicle fuel systems called Nano Fuel System that reduces fuel consumption and minimize exhaust emissions was studied in the present work. The fuel before entering the fuel chamber was conditioned at certain temperature and pressurized. So that the fuel can be fogged up to reach nano size. The research was expected to produce engine performance with reduced exhaust emissions and more fuel economy. The model was a heated fuel tank that serves to convert liquid fuel into a gas phase. It was conducted by heating fuel at temperatures of 25, 50, 75, and 100 oC as well as in pressure conditions of 1, 3, 5, and 7 bar. Initial preparation of the test equipment includes injector test bench and tune-up the engine, while test equipment in the form of emissions test and acceleration test was carried out as a parameter to determine the success rate of the experiment. CO levels decreased as the average fuel temperature rose by 7% at 3 bar pressure and 25.45 % at 5 bar pressures. This indicates that the presence of a heated fuel tank will increase combustion process so that fuel consumption will be more efficient. The levels of carbon dioxide emissions produced indicate that they are below the standard limits of CO2 emissions. The well-installed heated fuel tank worked well as it was seen at the lowest HC level drop at 100 0C with a 3000rpm spin of 6.23 %. This indicates fuel consumption is increasingly efficient.
