国内外工业的飞速发展，发动机排放引起的能源和环境污染问题越来越受到人们的关注，双燃料发动机技术在世界各国受到了高度的重视。双燃料发动机即是能使用两种燃料的发动机，双燃料发动机一般除使用汽油、柴油之外，还可以使用替代燃料，当使用替代燃料可以有效降低发动机排放的污染。由于双燃料发动机具备高效率、环保、控制灵活等特点，双燃料发动机技术很快成为LNG船舶的主流方向。本文通过分析对双燃料发动机的结构原理分析和特性研究，柴油-天然气双燃料发动机能够以原柴油机为基础，外挂一套天然气燃料控制系统，使其既可以以单一柴油模式工作，也可以转换成柴油、天然气双燃料掺烧模式工作。与传统柴油发动机作对比，了解船舶双燃料发动机的优势与不足，分析双燃料发动机技术在船舶领域广泛应用的能力。

With the rapid development of domestic industry, there has an increased in the numeber of people paying attention to environmental pollution which caused by engine emission. The technology of double fuel engine has been hignly valued by different countries in the world. Double fuel engine is a kind of engine which can not only use two fuel, but also use alternative fuel, instead of gas and petrol. In addition, one of advantages of using alternative fuel is it could decrease polloution released by engine efficiently. Due to the benefits that the double fuel engine has several characteristic includes hign efficiency, environmental protection, easy to control, this technology becomes LNG board development mainstream direction soon. In this article, it will discuss the original principle of double fuel engine structure and analyse its features. Diesel- gas double fuel is an engine that is based on diesel engine with gas fuel control system, which makes it possible to work both by small bore diesel engine and another operating mode that transfer diesel to gas. What is more, by comparing with traditional diesel engine, it can be known the disadvanges and advantages of double fuel engine better and people can be able to analyse if the technology of double fuel engine can be used widely in the board area.
