摘 要
柴油机被广泛应用于国民经济各个领域,在人类生活中发挥着极其重要的作用。然而,大量使用柴油机造成的后果是石油资源消耗的急剧增加和环境污染的日益严重,这个矛盾一直困扰着世界各国。
随着现代工业文明的进一步发展和城市机动车数量的日益增多,传统柴油机尾气排放已成为城市空气污染的主要来源。随着人们对环境污染重视程度的提高,世界各国对柴油机排放的限制也日益严格。采用天然气作为代用燃料可以降低排放,同时改善燃料消耗结构,有利于缓解石油危机。我国是一个发展中国家,天然气资源丰富,结合我国国情,使用代用燃料天然气, 具有重要的战略意义。
G)的方式,针对D611 4 型车用增压发动机进行了原机和双燃料发动机的对比实验,实验结果表明, CNG在增压发动机上的掺烧需要遵循一定的掺烧策略才能保证良好的动力性能和实现较低排放。
在实验室大量实验数据的基础上,采用电子控制技术,自行开发设计了
~G双燃料供给系统,G掺烧的控制。论文详细介绍了该双燃料电控系统的研制过程,包括硬件结构、软件模块以及控制方式。
论文最后分析了电控系统的不足和下一步完善需要进行的工作。关键字:G掺烧,双燃料系统,电子控制

Abstract
Diesel engines have been used in many fields and are playing an important role in people’s ,the result of large number of diesels is that the consumption of oil resources is increasing sharply and the environment is being
polluted a contradiction has bothered the world for a long time.
With the development of modem industry culture and more urban vehicles, the emission of diesel engines has been the main contribution to the air pollution in the attention increasingly given to environmental pollution, restriction of diesel engine emission in many countries is ing more and more pressed Natural Gl has been used widely as an alternative fuel to reduce exhaust ’s more,it Can amend the fuel
consumption’S configuration to be favorable to alleviate oil is a
developing country with abundant Natural Gas this alternative fuel
serves widely for China,it may have important strategic significance.
This thesis firstly focuses on the way of G in turbocharged diesel at the automobile diesel engine of the type of D6 1 14,some experiments contrasted the differences in performance between the G
dual fuel engine and the mere diesel result shows也at some suitable
strategies must be followed in the use G in turbocharged diesel engines to
certify the good dynamic performance and low emission.
Based on the the mass experimental data,taking advantag
