Abstract
Keinginan untuk membuat emisi mesin diesel lebih ramah lingkungan memacu banyak penemuan salah satunya menggunakan bahan bakar dual fuel, proses pencampuran bahan bakar gas dan udara sangat mempengaruhi emisi mesin diesel, salah satu cara mengontrol proses pencampuran bahan bakar gas dan udara ialah dengan mengatur geometri lubang diameter injektor. Tujuan penelitian ini adalah dengan mengubah geometri injektor bahan bakar gas kemudian diteliti bagaimana proses pencampuran bahan bakar gas dengan udara, dan bagaimana efeknya terhadap emisinya. Penilitan ini berbasis simulasi menggunakan Solidwork flow simulation 2016 untuk melihat proses pencampuranya dan software GT-Power 7.4 untuk mengetahui emisi NOx, CO, dan HC. Hasil yang diperoleh dari penelitian ini dengan menggunakan variasi diameter injektor 1.0 mm mampu mengurangi emisi NOx sebesar 14,3% dibanding injektor dengan diameter 3.0, 2.5, 2.0, 1.5. pada injektor dengan diameter 2,5 mm menghasilkan emisi HC dan CO paling rendah dibanding injektor lainya dengan presantase pengurangan sebesar 6% untuk HC dan 7,73% untuk CO.

The desire to make diesel engine emissions more environmentally friendly spurs many discoveries, one of which is using dual fuel diesel engine, the process of mixing gas and air fuels greatly influences diesel engine emissions, one way to control the process of mixing gas and air fuels is to set the geometry of diameter injector. The purpose of this study is to change the geometry of the gas fuel injector and then examine how the process of mixing fuel with air, and how it effects the emission. This research is based on simulation using Solidwork flow simulation 2016 to see the mixing process and GT-Power 7.4 software to determine NOx, CO, and HC emissions. The results obtained from this study using a 1.0 mm variation diameters injector were able to reduce NOx emissions 14,3% compared to injectors with diameters 3.0, 2.5, 2.0, 1.5 mm. on injectors with a diameter of 2,5 mm produce the lowest HC and CO emissions compared to other injectors with reduced presantase of 6% for HC and 7,73% for CO.
