Diesel Engine Performance Improvement by Closed-loop Injection System

噴射系クローズドループシステムを用いたディーゼルエンジンの性能向上

The needs for precise combustion control are continuously growing now to realize a higher level compatibility between attractive performance (e.g.higher heat efficiency, higher torque, etc.) and environmental protection requirement. To control combustion, i.e. to design heat release rate, the authors consider that following 3 factors are important, i) design freedom, ii) compensation, and iii) robustness. They developed intelligent Accuracy Refinement Technology (i-ART) to accomplish these factors for injection rate control. It is the world’s first system that realizes closed-loop fuel injection control by direct detection of the injection pressure using a pressure sensor built-in to the injector. In this paper, the importance of injection rate feedback technology to achieve precise combustion control is discussed.ディーゼルの魅力である高い熱効率や大トルクを最大限に引き出す技術として世界初の噴射系クローズドループシステムを開発した．本システムにより燃料噴射をこれまで以上に緻密に制御し，生涯にわたり補償できる．更にインジェクタ内圧力を連続的に捉え燃料性状を検出することもできる．これらの開発状況について報告する．
