Abstract

Seiring dengan perkembangan didunia maritim, permintaan akan kebutuhan kapal dengan performa yang sesuai semakin meningkat. Pada saat ini kapal dengan ukuran 30 tonasse sedang ramai dibahas. Peningkatan performa dapat dilakukan dari berbagai aspek, salah satunya dengan menggunakan turbocharger. Langkah pertama yang dilakukan adalah mengumpulkan spesifikasi data dari marine diesel engine tersebut. Prediksi performa mesin dilakukan dengan pemodelan rancangan mesin yang berbasis simulasi. Simulasi mencakup seluruh bagian mesin mulai dari dimensi, aliran udara masuk-keluar, bahan bakar, sistem injeksi, dsb. Prediksi performa mesin dilakukan dengan menggunakan tiga turbocharger dengan spesifikasi berbeda. Dalam menjalankan simulasi dibuat beberapa kasus berdasarkan putaran mesin 800 hingga 2200 RPM. Simulasi dengan software dilakukan untuk menghasilkan karakteristik dari performa mesin seperti torsi, daya, konsumsi bahan bakar, tekanan, dsb. Turbocharger yang digunakan pada simulasi yaitu GT2052-3, GT2052-1, dan GT1241. Brake power tertinggi dihasilkan oleh mesin dengan penggunaan turbocharger GT2052-3 menghasilkan daya sebesar 129.824 HP dengan efisiensi kompresor 61.4%. Brake power pada penggunaan turbocharger GT2052-1 menghasilkan daya sebesar 125.549 HP dengan efisiensi kompresor 73.9%. Brake power pada penggunaan GT1241 menghasilkan daya 71.172 HP dengan efisiensi kompresor 47.4%. ========================================================================================================== Along with the developments of the maritime world, ship demand with the appropriate performance increase. At this time the ship with the size of 30 GT being crowded discussed. The way to improved it performance can be done from various aspects, one of it is by installed a turbocharger. The first step taken was to collect data specifications of the marine diesel engine. Performance predictions obtained by modeling the engine in simuation software. Simulation covers the entire engine from the dimensions, air flow in-out, fuel injection systems, etc. Engine performance predictions is done by installation of three turbocharger with different specifications. The simulation process was made into several cases based on the engine rotation 800, 1000, 1200, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2200 RPM. Simulation by software is made to obtained the characteristics of engine performance such as torque, power, fuel consumption, pressure, etc. Turbochargers used in the simulation are GT2052-3, GT2052-1, and GT1241. Highest brake power generated by the engine installed with GT2052-3 turbocharger is 129.824 HP with 61.4% compressor efficiency. Brake power engine installed with GT2052-1 turbocharger generated power for 125.549 HP with 73.9% compressor efficiency. Brake power engine installed with GT1241 generated power for 71.172 HP with 47.4% compressor efficiency.
