Abstract

Transportasi yang marak digunakan di indonesia adalah kendaraan berupa motor dan mobil, sekaligus pula ikut meningkatnya ketergantungan akan konsumsi bahan bakar minyak (BBM). Salah satu sumber energi yang bersifat renewable yang dapat dimanfaatkan adalah etanol yang asalnya dari tumbuhan jagung, gandum, dan yang lainnya. Uap etanol di gunakan untuk penambahan bahan bakar minyak untuk membantu kinerja mesin motor. Dalam penelitian ini saya menggunakan uap etanol sebagai campuran bahan bakar motor dan menguapkan etanol tersebut dengan suhu 400C dan di campur 3 jenis bahan bakar premium pertalite dan pertamax. Temperatur uap etanol pada penggunaan bahan bakar minyak terhadap performa dan efisiensi sepeda motor 4 langkah dengan menggunakan variasi temperatur sebesar 400C, cara kinerja uap etanol dengan bukaan full dimasukan melalui intake manifold. Setelah melakukan pengujian didapatlah hasil bahwa daya terbaik didapatkan dari tambahan uap etanol dari 3 jenis bahan bakar tersebut. Performa mesin sepeda motor yang diujikan sehingga mampu meningkatkan tenaga motor dari horsepower 28,6 menjadi 29,1 dan torque dari 29,56 menjadi 29,70 untuk bahan bakar premium, dan pertalite hp30,9 menjadi 31,0 dan torque dari 31.46 menjadi 32,12 pertamax juga meningkat dengan suhu pemanas dari horsepower 30,8 menjadi 31,0 dan torque dari 31.50 menjadi 31,76.

Abstract

Everyone uses transportation as a means of getting to different locations. There are three categories for the actual modes of transportation: air, sea, and land. People typically use ground transportation, such buses, cars, and bicycles, for daily errands and commutes to the office since these modes of transportation are more convenient and quick to use. The electric bicycle is one of the vehicles that is currently being developed. The development of electric bicycles is necessary since they are simple and comparatively inexpensive to produce. Naturally, an electric bicycle needs a motor to propel it. A DC motor needs a voltage that enters the field coil in the same direction in order to generate mechanical energy. Electromotive force is produced by the armature coil while magnetic force is produced by the field coil. When the armature coil current interacts with the magnetic field, it produces the torque (T) that powers the motor. A DC motor has windings, and the quantity of windings in the motor can change its torque and output. The author of this study employs a DC motor, and alterations are planned to the windings through both an increase and a decrease in winding count. The objective is to ascertain how a 250W electric motor's torque and power are affected by the number of windings. According to the study's findings, the torque and power obtained at the start of the standard winding test were 0.55 and 5.7, respectively, when the RPM reached 100.4. When the rpm hits 77.8, adding coils results in a torque of 0.55 and a power of 4. When the rpm reaches 131.3 and the torque is 5.5, the power is 7.5 after the coils are reduced. Thus, the rpm and power generated decrease with the number of windings. Both the resulting rpm and the power released are inversely proportional to the reduced winding.
