本文针对特种船在低负荷下主机燃烧工况恶劣的问题进行优化研究，首先对其燃烧工况进行分析并提出定速模式的优化措施，运用数学模型进行验证，之后在该船上进行工程改造将定速装置应用于此船，最后将定速模式下主机的性能参数与该船原模式进行对比，证明定速装置有效地改善了主机的燃烧性能。
This paper is conducting an optimization study on the special ships' serious issue during their main engine's combustion conditions under low load, firstly, I analyzed its combustion conditions and came up with the optimization solution of the constant speed mode, and I utilized the math model to certify the assumptions; then I conducted the engineering reform by applying the constant speed mode devices to those ships; in the end, I made a comparison of the performance parameters between the main engine's new mode and its original mode, I testify that the constant speed mode can effectively improve the combustion performance of the main engine.
