Abstract

Salah satu penyumbang emisi paling banyak di dunia adalah penggunaan mesin diesel. Kebutuhan akan mesin ini semakin tahun semakin menigkat dan secara tidak langsung emisi yang ditimbulkan oleh mesin diesel juga semakin meningkat. Bahan bakar diesel oil (B0) juga meningkat setiap tahun. Salah satu cara untuk mengatasi beberapa masalah tersebut adalah dengan memodifikasi mesin diesel menjadi mesin diesel berbahan ganda. Bahan bakar lainya selain diesel oil (B0) akan menyumbang energi pada saat pembakaran dan hal tersebut akan mengurangi konsumsi penggunaan diesel oil (B0). Karakteristik dalam ruang bakar juga akan dipengaruhi oleh sifat second fuel. Emisi hasil pembakaran akan berkurang jika second fuel yang digunakan secara alami tidak mengandung unsur pembentuk emisi, begitu juga dengan performa dari mesin diesel. Amonia bisa menjadi solusi untuk mengurangi emisi hasil pembakaran dari diesel karena secara unsur kimia tidak mengandung unsur carbon dan dapat mengurangi konsumsi bahan. Penelitian ini bertujuan untuk mengamati perubahan karakteristik mesin diesel setelah penginjeksian ammonia dengan cara penginjeksian pada intake manifold dengan bantuan Elektrical Control Unit sebagai pengatur waktu penginjeksian. Amonia akan diinjeksikan dengan waktu yang beragam berdarsarkan derajat roda gila. Hal tersebut juga bertujuan agar ammonia diinjeksikan bertepatan dengan fase hisap mesin diesel. Penelitian ini menghasilkan kesimpulan bahwa emisi CO2 dan smoke opacity akan menurun sejalan dengan pertambahan jumlah ammoniam tapi NOx meningkat. Pada aspek performa, semakin lama waktu injeksi ammonia maka daya keluaran dan torsi semakin menurun jika dibandingka dengan diesel dengan bakar diesel oil (B0) saja. Namun, Spesific Oil Consumtion semakin baik sejalan dengan lama injeksi ammonia.

One of the world's biggest contributors to emissions is the use of diesel engines. The need for this engine is increasing year by year and indirectly the emissions caused by diesel engines are also increasing. Diesel fuel oil is also increasing every year. One way to overcome some of these problems is to modify diesel engines into dual-material diesel engines. Other fuels other than diesel will contribute energy during combustion and this will reduce the consumption of diesel oil. The characteristics in the combustion chamber will also be affected by the properties of the second fuel. Combustion emissions will be reduced if the second fuel used naturally does not contain emission-forming elements, as well as the performance of diesel engines. Ammonia can be a solution to reduce emissions from diesel combustion because it does not contain carbon and can reduce material consumption. This study aims to observe the changes in the characteristics of diesel engines after ammonia injection by injecting on the intake manifold with the help of the Electronic Control Unit as an injection timer. Ammonia will be injected at various times depending on the degree of the flywheel. It also aims for ammonia to be injected to coincide with the suction phase of diesel engines. This study concluded that CO2 emissions and smoke opacity will decrease in line with the increase in ammonia but NOx increases. In terms of performance, the longer the ammonia injection time, the lower the output power and torque when compared to diesel with diesel fuel alone. However, Specific Oil Consumption gets better in line with the length of ammonia injection.
