Abstract
Dalam beberapa tahun terakhir permintaan bahan bakar fosil semakin meningkat, hal ini dapat menyebabkan cadangan bahan bakar fosil semakin menipis. Untuk mengurangi penggunaan bahan bakar fosil diperlukan energi alternatif. Salah satu energi alternatif yang dapat digunakan untuk menggantikan bahan bakar fosil adalah LPG (Liquidfied Petrolium Gas). Penggunaan bahan bakar alternatif LPG pada mesin diesel dilakukan dengan mengkonversi mesin diesel menjadi berbahan bakar ganda. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan dual fuel LPG-Diesel terhadap kinerja mesin meliputi daya, torsi, dan konsumsi bahan bakar. Penelitian dilakukan menggunakan mesin Yanmar TF 85 MH pada putaran engine 2000 RPM dengan variasi pembebanan 1000, 1500, 2000,2500, dan 3000 watt pada bahan bakar diesel, dual fuel dengan variasi bukaan injektor 3 ms, 4 ms, 5 ms dan menggunakan konvensional konverter kit . Berdasarkan hasil penelitian, penggunaan LPG pada sistem dual fuel ini dapat menggantikan konsumsi bahan bakar solar hingga 73% pada percobaan variasi bukaan injektor selama 3ms, 86% pada bukaan injektor selama 4 ms, 93% pada bukaan injektor selama 5ms, dan 82% pada percobaan menggunakan alat konvensional. Pada penggunaan dual fuel terjadi penurunan daya dan torsi rata-rata hingga 1.81% pada bukaan injektor selama 3 ms, 0.94% pada bukaan injektor selama 4 ms, 1.33% pada bukaan injektor selama 5 ms, dan 1,95% ketika menggunakan alat konvensional. Ketika menggunakan dual fuel terjadi penurunan konsumsi bahan bakar spesifik hingga 42% pada bukaan injektor selama 3 ms, 39% pada bukaan injektor selama 4 ms, 44% pada bukaan injektor selama 5 ms, dan 31% ketika menggunakan alat konvensional.

In recent years the demand for fossil fuels has increased, this can cause fossil fuel reserves to be depleted. To reduce the use of fossil fuels, alternative energy is needed. One of the alternative energies that can be used to replace fossil fuels is LPG (Liquid Petroleum Gas). The use of alternative fuels for LPG in diesel engines is done by converting diesel engines into dual fuel. This study aims to determine the effect of using dual fuel LPG-Diesel on engine performance including power, torque, and fuel consumption. The study was conducted using a Yanmar TF 85 MH engine at 2000 RPM engine speed with variations in loading of 1000, 1500, 2000, 2500, and 3000 watts on diesel fuel, dual fuel with variations in injector openings of 3 ms, 4 ms, 5 ms and using a conventional converter. kits. Based on the results of the study, the use of LPG in this dual fuel system can replace diesel fuel consumption up to 73% in the 3ms injector opening variation experiment, 86% in the 4ms injector opening, 93% in the 5ms injector opening, and 82% in the experiment. using conventional tools. When using dual fuel there is a decrease in power and average torque of up to 1.81% at injector opening for 3 ms, 0.94% at injector opening for 4 ms, 1.33% at injector opening for 5 ms, and 1.95% when using conventional tools. When using dual fuel there is a decrease in spesific fuel consumption of up to 42% at the injector opening for 3 ms, 39% at the injector opening for 4 ms, 44% at the injector opening for 5 ms, and 31% when using conventional tools.
