Abstract

NOx one of the exhaust emissions is harmful to human health. Many methods can reduce NOx emission, one of them is water in fuel emulsion. By using experiment, research has been conducted in surfactant selection. The results of experiment show 4 surfactant, which is best used to the diesel engine is tween 80 and span 80. This experiment needs some water contents variation emulsifier with 10%, 15%, and 20%. In this different variation of water is very influential on performance and NOx emissions. Using water fuel emulsion of 10% in SFOC can increase 216,2 g/Kwh or 11.6% compared to Pertamina Dex of fuel. However, the water used in fuel emulsion of 15% and 20% in SFOC increased to compare 10% emulsion. The effect of water use in fuel emulsion can reduce NOx emission. Water in fuel emulsion can be decreased to 0.216 g/Kwh or 50.5%. Generally, the emission level of a diesel engine that has been using water in fuel emulsion can be improved until entering on Tier 3 specification of IMO rules. ================================================================= NOx salah satu emisi gas buang yang berbahaya bagi kesehatan manusia. Banyak metode yang ditawarkan untuk mengurangi emisi NOx salah satunya adalah bahan bakar emulsi air . Dengan menggunakan percobaan, penelitian telah dilakukan pemilihan surfaktan. Hasil percobaan menunjukkan dari 4 surfaktan, yang baik digunakan untuk mesin d iesel yaitu tween 80 dan span 80. Dalam percobaan ini diperlukan beberapa kandungan variasi air untuk pengemulsi terdiri dari 10%, 15%, dan 20%. Dalam variasi air yang berbeda ini san gat berpengaruh terhadap performa dan emisi NOx. Menggunakan emulsi bahan bakar air 10% di SFOC dapat meningkat 216,2 g / Kwh atau 11,6% dibanding bahan bakar Pertamina Dex. Namun, air yang digunakan dalam emulsi bahan bakar 15% dan 20% di SFOC meningkat u ntuk membandingkan emulsi 10%. Pengaruh pada penggunaan bahan bakar emulsi dapat mereduksi emisi NOx . Bahan bakar emulsi dapat menurun hingga 0,216 g / Kwh atau 50,5%. Umumnya, tingkat emisi mesin diesel yang telah menggunakan bahan bakar emulsi dapat diti ngkatkan sampai masuk pada peraturan IMO spesifikasi Tier 3.
