ANALYSIS OF THE EFFECT OF ADDING ECO RACING ON PERTAMAX FUEL ON THE PERFORMANCE OF 2 STOCK MOTOR ENGINES

The technology of saving and reducing air pollution on motorized vehicles with fuel originating from petroleum continues to be researched. Fuel savings occur due to the depletion of petroleum supplies so that humans find technology to streamline engine performance, research is also carried out to find alternatives or add additives to motor vehicles. Materials that were not previously considered as additional fuel were tested and assessed for their feasibility as saving substances and reducing air pollution in vehicle exhaust emissions. Eco racing is one of the appropriate fuels to be used as an additive to vehicle fuel. The purpose of this study is to determine the changes in power and torque on the engine after using. Pertamax and Eco Racing. Specific fuel consumption produced by fuel. Pertamax and Eco Racing blends Pertamax and eco racing fuels. Based on the results of the tests that have been carried out, it can be concluded that.The phenomenon obtained from this test is that the power and torque produced are greater using pure Pertamax fuel, namely at 4000 rpm to 4200 rpm rotation, producing 8.6 kW of power, after 4200 rpm the power generated decreases at 4400 rpm. with the resulting power of 8.3 kW, then in the next round, namely at 5400 to 5600 rpm the power generated increases by 9 kW.
