摘要/Abstract

摘要： 船用低速发动机是远洋船舶推进的首选动力，具有经济性好、可靠性高等优势。本文主要介绍了低速机的技术特点，回顾低速机技术发展的历史，基于当前低速机技术研究的现状，重点分析了不同低速机有害排放物和温室气体减排技术的原理和特点。对于低速柴油机选择催化还原技术是目前最为主流的氮氧化物减排手段；双燃料技术则是当前综合应对氮氧化物（NO_x）、硫氧化物（SO_x）、黑碳以及温室气体减排的最佳选择；零碳和智能技术将是低速机未来的发展方向。

Abstract: Marine low speed engine is the first choice for sea-going ship propulsion power， due to economy and reliability. The technology feature and development process of low speed engine were reviewed. According to current low speed engine technology development status， the principle and feature of several emission and green house gas reduction solutions are analysed. Selective catalytic reduction（SCR） for diesel engine is the most popular solution to reduce NO_x. Dual fuel technology is current best choice for the integrated solution for NO_x， SO_x， black carbon and green house gas reduction. Neutral carbon and smart will be the future development directions of low speed engine.
