Abstract

Ketersediaan bahan bakar fosil untuk pengoperasian motor diesel kini semakin berkurang. Disamping itu, permasalahan lingkungan terkait global warming, salah satunya tentang polusi udara sangat mengkhawatirkan. Penggunaan minyak kelapa sawit sebagai bahan bakar dapat menjadi salah satu jalan keluar berkurangnya ketersediaan bahan bakar fosil untuk pengoperasian mesin diesel. Penggunaan biodiesel minyak kelapa sawit memiliki kadar emisi NOx yang cukup tinggi. Penambahan air pada bahan bakar dapat memberikan jawaban untuk mengurangi emisi NOx hasil pembakaran mesin diesel. Penelitian ini membahas pemanfaatan minyak kelapa sawit (Crude Palm Oil) dan penambahan air dalam bahan bakar. Pengujian dilakukan dengan cara eksperimen menggunakan beberapa variasi bahan bakar. Variabel bahan bakar emulsi yang digunakan adalah bahan bakar emulsi 10% & 15 %. Analisa yang dilakukan meliputi peforma, hasil proses pembakaran serta emisi NOx bahan bakar emulsi. Dari hasil pengujian performa pada mesin diesel, penggunaan bahan bakar emulsi 10% dan emulsi 15% menghasilkan peforma lebih rendah dari bahan bakar B20 kelapa sawit maupun Dexlite, nilai SFOC kedua bahan bakar tersebut 377,3 gr/kWh dan 410,4 gr/kWh. Dari hasil pengujian proses pembakaran, didapatkan bahan bakar emulsi 10% dan 15% mempunyai ignition delay yang lebih lama pada combustion pressure peak yang lebih rendah daripada bahan bakar B20 dan Dexlite. Emisi bahan bakar emulsi 10% dan emulsi 15% memiliki NOx sebesar 2,6 gr/kWh dan 2,5 gr/kWh pada putaran 2200RPM dan beban 100%. ===================================================================================================== The availability of fossil fuels for the operation of diesel engine is now diminishing. The environmental issues related to global warming, one of them about air pollution is very worrying. The use of palm oil as a fuel can be one way out the reduced availability of fossil fuels for the operation of diesel engines. The use of palm oil biodiesel has high levels of NOx emissions. The addition of water to the fuel can provide an answer to reduce the NOx emissions of diesel engine. This study discusses the utilization of crude palm oil and the addition of water in fuel. This experiment using several variations of fuel. The emulsion fuel variables used are DWE 10% & 15%. The analyzes include performance, combustion process and NOx emissions. From the results of performance testing on diesel engines, the use of DWE 10% and 15% resulted in lower performance than B20 palm oil and Dexlite, the value of SFOC both fuel is 377.3 gr / kWh and 410.4 gr / kWh . From the combustion test results, DWE 10% and 15% has a longer ignition delay in combustion pressure peak which is lower than B20 and Dexlite fuel. DWE 10% and 15% have NOx of 2.6 g / kWh and 2.5 g / kWh at 2200 RPM at 100% Load.
