Research on Matching of Main Engine and Turbocharger on Sail-Assisted Ship

摘要

To research the matching of main engine and turbocharger on sail-assisted ship, a 76000 deadweight tonnage cargo ship with 5S60MC main engine and TCA66 turbocharger was selected. The simulation model of working process of the engine was established, with AVL BOOST software, and verified by bench test results. Then, the model was used to analyze the matching of main engine and turbocharger, at constant speed mode of the main engine and constant speed mode of the ship. The results show that, the matching of main engine and turbocharger is acceptable, on the selected sail-assisted ship. However, special attentions should be paid to the turbocharger when the engine load is above 85.6% of the rated power at constant speed mode of the ship, to avoid surge of the comnressor.
