High Efficiency and Clean Diesel Combustion Using Double Premixed Ignition (Second Report) - Influences of Environmental Variation and Fuel Cetane Quality on New Concept Combustion

二段着火予混合燃焼を活用した高効率クリーンディーゼル燃焼（第2報）

Combustion robustness of the new concept combustion named D-SPIA was investigated for ambient temperature, engine coolant temperature and fuel cetane quality. Through these tests, the authors found out that heat release rate of the D-SPIA could be maintained at a desired crank angle by control of air-fuel ratio and/or injection timing based on changes in the environmental conditions and stability of the D-SPIA was maintained even when using of a low cetane index fuel. Finally, they tested a prototype engine using the D-SPIA and verified that it had a potential to meet Euro6 regulation without any DeNOₓ after-treatment and fuel penalty.新コンセプトのD-SPIA燃焼の外気温度、冷却水温および燃料性状変化の影響を調査した。その結果、環境変化に対して、空燃比と噴射時期の制御で対応できることが確認でき、低セタン指数燃料でも安定した燃焼を維持可能であることも分かった。また、NEDC(New European Driving Cycle)の評価を行った結果、NOₓ 後処理なし･燃費悪化なしでEuro6規制値を満足するポテンシャルがあることを確認した。
