摘　　要：针对柴油机目前广泛应用的3种燃油喷射系统(电控单体泵系统、电控泵喷嘴系统、共轨燃油喷射系统)进行分析,从专利申请趋势、技术发展趋势、区域分布、主要竞争机构以及在农用发动机中的应用等角度探讨其竞争态势。结果表明,电控单体泵、电控泵喷嘴系统整体技术已趋于稳定,目前技术发明主要布局在系统零部件或新材料研发等外围专利上,共轨燃油喷射系统技术已趋于成熟,德国和日本在相关技术领域处于绝对领先地位,我国在该领域的研究与开发尚处于起步阶段。Based on patent analysis into 3 kinds of diesel engine fuel injection system（ electronically controlled unit pump system,electric control unit injector system,common rail fuel injection system）,the competitive situation of these systems were investigated from 5 aspects,including patent application trend,technology development trend,regional distribution,rival agencies and applications in agricultural machinery engine. It was shown that the development of electronically controlled unit pump system and electric control unit injector system tended to be stable,with new technical inventions laying out in system components and new materials. Common rail fuel injection system related technologies were going to be mature. Germany and Japan hold absolutely leading positions in this field,while the research and development of China in this field was still in its infancy.
