Abstract
Marine diesel digunakan sebagai marine propulsion engine
mempunyai operasi yang khusus. Dalam pengoperasiannya faktor
medan, faktor cuaca, faktor tahanan kapal yang berbeda serta
aturan Marpol makin diperketat merupakan penyebab operasi
motor. Untuk itu memerlukan desain motor yang dapat mengatasi
permasalahan ini. Penggunaan Wide Operating Speed Range
(WOSR) merupakan salah satu alternatif untuk menyelesaikan
permasalahan tersebut. Prinsip kerja WOSR dengan pengaturan
injection timing yang tepat untuk menghasilkan daya yang besar
dan emisi yang rendah. Untuk mempelajari digunakan power
prediction secara simulasi. Dengan menggunakan data-data motor
sebenarnya sebagai input data simulasi maka diperoleh kinerja
motor yang diinginkan. Hasil penelitian ini didapatkan daya yang
mirip pada putaran 1600 rpm – 1800 rpm. Pada putaran 1600 rpm
menunjukkan daya sebesar 746,4 kW, torsi 4458,23 Nm dan Bsfc
505,0717 g/Kwh. Pada 1700 rpm menunjukkan daya sebesar
746,85 kW, torsi sebesar 4195,22 Nm dan Bsfc 547,3883 g/kWh.
Serta pada 1800 rpm menunjukkan daya sebesar 746,68 kW, torsi
3961,25 Nm dan Bsfc 587,0963 g/kWh.
==============================================================================================
A marine diesel engine used as marine propulsion has a specific
operation. In its operation, there are various fields, weathers, and
ship’s resistances. Moreover, MARPOL rules about exhaust gas
were being tightened. Based on the afore mentioned case, it
requires a design of engine that can resolve these problems, one
of the alternatives is by applying Wide Operating Speed Range
(WOSR). The working principle of WOSR is setting the injection
timing properly to produce large power and low emissions. In this
thesis, power prediction simulation was used. By using the actual
data of engine cycle as an input of simulation data, engine
performance was obtained as expected. From this research, the
powers obtained were similar at speed 1600 rpm – 1800 rpm. At
1600 rpm, it indicated power of 746.4 kW, torque of 4458.23 Nm,
and BSFC of 505.0717 g / Kwh. At 1700 rpm, it indicated power
of 746.85 kW, torque of 4195.22 Nm, and BSFC of 547.3883 g /
kWh. Furthermore, at 1800 rpm, it indicated power of 746.68 kW,
torque of 3961.25 Nm, and BSFC of 587.0963 g / kWh.
