Abstract
Penggunaan mesin diesel pada masa sekarang semakin banyak dan hal itu berbanding lurus dengan semakin menignkatnya emisi yang dihasilkan. Salah satu alternatif bahan bakar untuk diesel yang dapat mengurangi emisi adalah LPG (Liquified Petroleum Gas). Penggunaan LPG pada meisn diesel dapat dilakukan dengan memosif mesin diesel dan membuat konverter gas khusus untuk memasukkan gas LPG ke ruang bakar dari meisn diesel. Penelitian ini bertujuan untuk mengetahui kadar emisi NOx yang dihasilkan oleh mesin diesel dual fuel LPG – solar berbasis ECU. Penelitian ini dilaksanakan dengan metode eksperimen dimana mesin diatur pada RPM 2000 dengan variabel bebas berupa beban 1000 watt,1500 watt,2000 watt,3000 watt, dan pengaturan bukaan injektor gas pada 3ms,4ms dan 5ms. Hasil yang didapat dari penelitian ini yaitu emisi NOx yang dihasilkan oleh mesin diesel dual fuel LPG-solar lebih kecil dibanding dengan mesin diesel dengan bahan bakar solar saja. Kadar emisi NOx terbesar yang dihasilkan oleh mesin diesel berbahan bakar solar terdapat pada beban 3000 watt yaitu dengan rata rata sebesar 371,274 ppm. Sedangkan untuk kadar NOx terbesar yang dihasilkan oleh mesin diesel dual fuel terjadi pada beban 3000 watt dengan rata rata sebesar 276,686 ppm untuk durasi bukaan injektor 3 ms, 223,411 ppm untuk durasi bukaan injektor 4 ms, dan 274,215 ppm untuk durasi bukaan injektor 5 ms.

The use of diesel engines today is increasing and this is directly proportional to the increasing emissions produced. One alternative fuel for diesel that can reduce emissions is LPG (Liquified Petroleum Gas). The use of LPG in diesel engines can be done by modifying the diesel engine and making a special gas converter to enter LPG gas into the combustion chamber of the diesel engine. This study aims to determine the levels of NOx emissions produced by the ECU-based dual fuel LPG-diesel diesel engine. This research was carried out using an experimental method where the engine was set at 2000 RPM with independent variables in the form of a load of 1000 watts, 1500 watts, 2000 watts, 3000 watts, and setting the gas injector openings at 3ms, 4ms and 5ms. The results obtained from this study are that the NOx emissions produced by the dual fuel LPG-diesel diesel engine are smaller than the diesel engine with diesel fuel alone. The highest levels of NOx emissions produced by diesel engines with diesel fuel are at a load of 3000 watts with an average of 371.274 ppm. Meanwhile, the highest levels of NOx produced by dual fuel diesel engines occur at 3000 watts of load with an average of 276.686 ppm for 3 ms injector opening duration, 223.411 ppm for 4 ms injector opening duration, and 274.215 ppm for 5 ms injector opening duration.
