To achieve the future emissions regulations with low particulate and Nox levels, both the engine combustion system and the fuel injection equipment will have to be improved. For the fuel injection ...

We have investigated the fundamental characteristics of unit injectors and pump-line-nozzle systems theoretically by a graphical analysis of characteristic lines. We have confirmed the higher ...

燃料は、供給ポンプ（1）によって燃料タンクのピックアップチューブ（2）を通り、エンジン電子制御ユニット（EECU）冷却コイル（3）を通り、そして燃料フィルターハウジング（4）。燃料フィルターハウジングには、プレフィルター（5）と水分離器（6）が ...

Abstract: Two diesel engines with electronically controlled unit injector were employed to investigate the number emissions and size distributions of the exhaust particles. One engine meets the ...

Abstract: The present work describes the development and partial validation of a mathematical model of a hydraulically actuated electronically controlled unit injector (HEUI). The HEUI analyses ...
