摘要
设计和研制YCD4B54柴油机,并针对研制过程中的技术要求、工艺流程,以及存在的技术关键与难点进行系统分析.结果表明:YCD4B54系列柴油机针对性地集成了多种机内处理技术,采用废气涡轮增压与中冷技术,能强化柴油机的动力;采用电控高压共轨燃油喷射系统,能提高喷油速率和燃油雾化水平;采用排气再循环+柴油氧化催化器+颗粒氧化催化器(EGR+DOC+POC)后处理技术方案,能保证柴油机具有良好的动力性和燃料经济性.
In this paper,the YCD4B54 diesel engine are designed and developed,and the technical requirements,process and the exist key technology and difficulty in the development process are analyzed systematically.The results showed that the YCD4B54 series diesel engine is integrated many internal processing technologies,the use of exhaust gas turbocharger and inter-cooled technology can strengthen the power of diesel engine,and the high pressure common rail electric control system can increase the fuel injection rate and fuel atomization level.Adopting the post processing technical scheme of exhaust gas recirculation＋diesel oxidation catalyst＋particulate oxidation catalyst（EGR＋DOC＋POC）,it can ensure the diesel engine has good power performance and fuel economy..
