Abstract

Dual fuel engine adalah salah satu solusi untuk mengurangi angka pengeluaran polusi udara yang disebabkan penggunaan bahan bakar diesel, dan menjadi tempat penerapan gas alam sebagai bahan bakar campuran. penambahan Mask pada air intake valve pada mesin dual-fuel engine Mesin Yanmar TF 85 MH Direct Engine yang bertujuan untuk membuat aliran udara menjadi tumble. Dan upaya meningkatkan performa mesin akibat penambahan mask. Yang pertama dilakukan adalah mengambil data dari mesin yaitu ukuran-ukuran valve, ruang bakar, dan lainya. Kemudian melakukan permodelan valve mask 3D menggunakan Autodek Inventor. Setelah permodelan dilakukanlah simulasi permodelan menggunakan CFD Ansys Fluent, untuk simulasi dilakukan dengan adanya variable jumlah mask pada valve sebanyak 3 dan 6 mask. Dan untuk valve lift sebesar 3mm dan 4mm. Hasil dari simulasi yang dilakukan dapat disimpulkan bahwa penambahan mask membuat intensitas turbulensinya meningkat. Dan penambahan jumlah mask sebanyak 6 buah adalah jumlah mask yang terbaik pada simulasi ini dengan itensitas turbulensi lebih tinggi dibandingkan dengan 3 mask. Dimana intensitas turbulensi mempengaruhi aliran turbulen yang terbentuk pada ruang bakar. ==================================================================================================== Dual fuel engine is one solution to reduce the amount of air pollution expenditure caused by the use of diesel fuel, and become the place of application of natural gas as mixed fuel. addition of Mask on intake valve water on dual-fuel engine Yanmar TF 85 MH Direct Injection Engine that aims to make airflow become tumble. And efforts to improve engine performance due to the addition of mask. The first to do is to retrieve data from the machine that is the valve sizes, combustion chamber, and others. Then do a 3D valve mask modeling using Autodek Inventor. After modeling the model simulation was done using CFD Ansys Fluent, for the simulation done by the variable number of mask on the valve of 3 and 6 mask. And for valve lifts of 3mm and 4mm. The result of the simulation can be concluded that the addition of mask makes the turbulence intensity increase. And the addition of 6 masks is the best mask number in this research with higher turbulence itensity compared to the amount of mask 3. where turbulence intensity influence turbulent flow which formed in combustion chamber.
