Design and development of fuel consumption meter on motorcycle based on injector pulse width using arduino uno microcontroller

Motorcycles equipped with fuel injection systems commonly utilize dashboard indicators to ascertain the amount of fuel remaining, resulting in riders having an imprecise understanding of fuel consumption. As a result, motorcyclists may find it difficult to evaluate fuel use during specific time periods. In order to tackle this issue, the researcher develops a digital gadget that employs a microcontroller to regulate performance. The device exhibits fuel usage data in relation to injector pulse width. Moreover, the device can also function as an educational tool for vocational high school students to acquire knowledge about the operation of EFI motorcycle fuel systems. This study employs a research and development methodology, with a specific focus on a 2021 Honda Beat FI motorbike that was tested in the Automotive Engineering Vehicle Testing Workshop at Universitas Negeri Padang. The analysis of experimental data during idle rotations at 20, 40, and 60 seconds reveals average percentage errors of 2%, 1.73%, and 11.76% correspondingly. This leads to an overall device error rate of 4.74% throughout all test situations. The data was obtained through a comparison between the measurement data from the device and the actual measurement data. The error rate signifies the device's precise measurement of fuel usage in real-world situations.
