Turbo Charge

Dalam pengoperasian kapal diperlukan keselamatan sesuai peraturan internasional dan peraturan nasional mengenai kelayakan kapal. Penelitian ini mengkaji tentang penyebab kerusakan pada permesinan di kapal UB. Istana Laut dan upaya yang dilakukan oleh personil kapal untuk memenuhi standar keselamatan kapal. Metode yang digunakan dalam penelitian ini adalah deskriptif kualitatif. Dari hasil penelitian diperoleh kesimpulan bahwa kerusakan yang terjadi pada permesinan kapal di kapal UB. Istana Laut disebabkan oleh bocornya bagian kanan mesin utama pada turbo charge dan indikator lampu emergensi pada mesin penyuplai daya tidak bekerja saat di test. Upaya yang dilakukan oleh personil kapal untuk memenuhi standar keselamatan adalah melakukan perawatan secara periodik menurut waktu kalender untuk penanganan longgarnya selang pemadam kebakaran dan membuat matrix daftar peralatan yang memiliki masa expired untuk penangannya baterai EPIRB dan HRU yang telah expired

Marine Diesel

The constant pressure turbo-charge system has now been increasingly adopted for marine diesel engines because of its higher thermal efficiency in the range of higher mean effective pressure. However, it seems that there has been no paper published on the exhaust gas pulsation of this sytem. In this study, a gas flow model of the constant pressure turbo-charged diesel engines was assumed as a basic and fundamental one, and an investigation was made of it. As a result, some characteristics of the exhaust gas pulsation of this system have been clarified and a mathematical simulation system has been established. It must be emphasized that the filling and emptying method which neglects wave propagation cannot simulate the pulsation, although it can simulate the average exhaust gas pressure and temperature of this system.

The noise of the engine and torsional vibration of the engine’s shafting is been tested. The engine is a direct injection turbo charge inter-cooling four cylinders one. In the testing, the original pulley and three different torsional vibration dampers are compared.The result shows that it can reduce the vibration of the shafting, triangular belt, the accessory, and can reduce 1 to 2 decibel of the engine’s sound power level by using the torsional vibration damper.

System Layout

Turbocharger has been widely implemented for internal combustion engine to increase an engine's power output and reduce fuel consumption. However, its operating temperature would rise to 340°C when engine stalls. This higher temperature may results in bearing wear, run-out, and stick, due to oil coking and insufficient lubrication. In order to overcome these problems, this paper employs Electric Water Pump (EWP) to supply cool liquid to turbocharger actively when the engine stalls. The system layout, operating timing, and duration of EWP are investigated for obtaining optimal performance. The primarily experimental results show that the proposed layout and control strategy have a lower temperature of 100°C than the conventional temperature 225°C.
