| Summary: | 碩士 === 國立高雄應用科技大學 === 電機工程系博碩士班 === 105 === In this study, a marine diesel engine of optimum operating conditions for superior engine performance and lower emission is researched. The experimental results showed that the lowest fuel oil consumption rate is occurred at 100% engine load. The corresponding scavenging pressure, engine speed, fuel-injection timing, engine torque, and brake horse power (BHP) under such engine operating conditions were 195.6 g/kW-hr, 0.22 MPa, 800 rpm, 20.8°, 8787.01 N-m, and 9815.2 HP, respectively. The engine operating parameters were adequately adjusted based on the results of both experimental analysis and model simulation in order to acquire superior engine performance and efficiency. The results could be provided a valuable reference for marine engine industry to improve the main engine performance and low emissions of air pullouts.
