Pengaruh Penambahan Zat Aditif terhadap Konsumsi Bahan Bakar pada Motor Bakar Bensin Suzuki 4-tak Dohc (16 Hp)

The level of motorized vehicle use is increasing every year and will lead to high fuel consumption. Then a vehicle that has good performance and minimum fuel consumption is needed. The government introduced a new fuel, pertalite, which has better fuel quality than premium. Additive substances are ingredients that are added to motorized fuel which are useful for increasing engine performance ranging from durability, acceleration to engine power. The purpose of this test is to find out how much fuel is used when testing braking, how much fueling has been mixed with additives when braking loads occur, analyzing the reduction of fuel mixed with additives and without additives mixed. So that the resulting fuel composition without using additives reaches max torque 5,488 Joules, power 2010.4 Watts, and mass flow rate 0,000082 kg / s with fuel consumption 0,4 l /hr, from substanceless testing additives and using the most maximal additives with a time of 120 seconds, 7000 rpm and a load of 2 kg, a comparison of the reduced use of fuel is 0.06 l / h. The fuel composition using additives reaches max torque 5.488 Joules, power 2010.4 Watts, and mass flow rate 0.000071 kg / s with fuelconsumption 0.36 l / hr. Testing with additives as a mixture of fuels in certain compositions can improve engine efficiency which has a low mass flow rate, but is proportional to the torque and power produced. Based on the testing and analysis that has been done, the best mixture composition for pertalite is 1: 1
