The effect of magnetic rotor variations on motorcycle 4-step injection modification on engine performance as a potential application of bioethanol
Keywords:
Combustion engine, Bioethanol, Variations in fuel mixtureAbstract
Various innovations in technology continue to be developed to improve engine performance and optimize the combustion process in the combustion chamber. Perfect combustion can improve the performance of the engine, while also maximizing the ignition system by modifying the pulser magnetic pickup to increase the spark from the spark plug in the combustion chamber, so that the air and fuel mixture burns more efficiently and the combustion is more complete. This research aims to explore the effect of variations in the magnetic rotor on a 4-stroke injection motorbike on engine performance, especially in the application of bioethanol fuel. The rotors used in this research include standard rotors that have been issued by the manufacturer of the vehicle, and the use of rotors that are modified by increasing the length of the mold by 2 mm, and the rotor is shortened by 2 mm. The experimental method used in this research, and the results show that a fuel mixture with 30% Pertamax and 70% ethanol produces a torque of 8.15 N.m and can produce a power of 5.9 kW, which is produced by treating the rotor. In this research, torque and power increased better than using standard rotors.
