Abstract

Penggunaan natural gas pada motor diesel mengakibatkan tidak terjadi pembakaran sempurna karena jumlah udara pembakaran menjadi berkurang sehingga menyebabkan AFR (Air Fuel Ratio) menjadi lebih rendah. Langkah yang dapat dilakukan untuk mengatasi permasalahan tersebut salah satunya dengan melakukan modifikasi pada piston crown. Akan tetapi, modifikasi yang dilakukan tentunya akan berpengaruh terhadap kadar emisi yang dihasilkan sehingga perlu dikaji lebih lanjut. Emisi yang akan dikaji pada penelitian ini antara lain NOx , Unburned Hydrocarbon (UHC), dan Methane Slip. Metode yang digunakan pada penelitian ini adalah eksperimen. Eksperimen dilakukan pada 4 kondisi antara lain piston standar single fuel, piston standar dual fuel, piston modifikasi single fuel, dan piston modifikasi dual fuel. Hasil yang didapat dari eksperimen yang dilakukan adalah piston standar dual fuel mampu menghasilkan emisi NOx dan UHC yang lebih rendah, sedangkan methane slip yang dihasilkan lebih tinggi. ================================================================================================ The utilization of natural gas on diesel engine generate the imperfection result of combustion, since amount of air in combustion chamber had reduced causing the number of air fuel ratio (AFR) getting lower. One of the solution can be taken to reduced the problem above is “Crown Piston Modification”. However, this modification will affect in the emission level generated by the diesel engine. So, it is required to do more observation. This observation will be focused on how much emission level such as NOx, Unburned Hydrocarbon (UHC), and Methane Slip gained in every piston modification. The experiment carried out in 4 type conditions, they are Standard Piston with Single Fuel, Standard Piston with Dual Fuel, Modificated Piston with Single Fuel, and Modificated Piston with Dual Fuel. Based on the experiment data, it can be concluded that the standard piston with dual fuel are able to gain lower level of NOx and UHC, but not in methane slip.
