Abstract

The performance of motorized vehicles that are more than five years old tends to decline. Today, fuel manufacturers are very diverse, even though they have the same octane rating. Each fuel certainly has different characteristics. The need for testing to determine the performance and consumption of the motor. This study aims to determine the effect of Pertamax, Shell Super, AKRA92 fuel with 92 octane on performance and efficiency, especially on automatic motorcycles Honda Beat FI 110cc in 2013. Fuel. From the dynotest results, the torque and power produced by the AKRA92 are 13.15Nm and 12.72HP, then Pertamax 11.51Nm and 11.91HP, the last is Shell Super 10Nm and 11.72HP. Meanwhile, from the test results of fuel consumption efficiency per 250 ml, namely AKRA 92 10.37km then Pertamax 9.95km and lastly Shell Super 9.64km. Of the three fuels, the most efficient in fuel consumption is AKRA92. Fuel that has high performance will automatically have a more complete combustion. If the resulting combustion is complete, the energy produced will be greater with the same amount of fuel. This is what causes the fuel that has high performance automatically fuel consumption will be low.

Abstract

The purpose of this study was to determine the value of the pump capacity at each suction pipe replacement and to determine the power value caused by the effect of replacing the suction pipe. In this research, there are several stages starting with the installation of a pump, measuring the flow of water, measuring the voltage and measuring the current of the water pump. Fluid flow rate is the volume rate or the volume of fluid flowing per unit time. How to measure the power of a single phase electric motor, which requires a tool called a clammeter where this tool can be used to measure the value of current and voltage. From the results of measuring the current and voltage values, the formula P = V x I, P = motor power value, V = voltage value and I = current value. The results showed that the maximum pump work on the replacement of the suction pipe with a size of 2 ½ inches with a power value of 212,2 watts, a pump capacity flow rate of 0,135 liters/second and a friction head of 0,000057368
