Simulation and Experiment on Engine Performance and BSFC for Two-Stage and Sequential Turbo Diesel

高過給・多量EGR の二段シーケンシャル過給ディーゼル機関のシミュレーションと実験

The two-stage and sequential turbocharging strategy was proposed in order to achieve both higher torque at low engine speed, and better fuel consumption at low and high engine speeds. According to results of simulation and engine experiments, the improvement in fuel consumption was obtained at both low and high engine speeds by using this turbocharging strategy. On the other hand, although fuel consumption at low engine speed was further improved by using low-pressure-loop EGR, fuel consumption at high engine speed was deteriorated because of the seriously increased exhaust back pressure.高過給・多量ＥＧＲのディーゼル機関で広範囲な運転領域をクリ－ン化してきた．また単段過給に高圧段過給機を追加した２段過給で低速域の空気量を増加させた．2段過給機関を実験し、低速と高速域の過給特性を調べ、機関燃費率の改善から走行燃費を向上させた．
