Evolution for Diesel Fuel Injection System - The New World by Ultra High Pressure Injection


Diesel engine management systems are increasingly becoming more and more complex, large-sized and expensive to meet stringent emissions regulations. The purpose of this development is to explore the way to build a simple and low-cost engine management system while maximizing the benefits of diesel engines. In order to achieve the purpose, the authors blended "Power" and "Smart". "Power" is the injection system which offers extremely high pressure 250 - 300 MPa. "Smart" is the world's first closed-loop control system which automatically corrects injection characteristics using pressure signals obtained from the injector built-in pressure sensor (i-ART: intelligent Accuracy Refinement Technology). It enabled the authors to create all-time high added value.クリーンディーゼル普及に貢献するため,エンジンからのエミッションをできるだけ下げて後処理システムを簡素にしトータルコストを低減することを開発方針とした.その実現のために,超高圧噴射の「力」と世界初の噴射特性のフィードバック制御による「知恵」との融合によりこれまでにない高付加価値を提供するものである.
