使用起動型鋰鐵電池對汽油引擎性能影響之研究
Effects of Performance Using the Startup Type Lithium Iron Batteries for Gasoline Engines
摘要
本研究主要是將傳統汽油引擎的鉛酸電池更換為起動型鋰鐵電池，並於汽油噴射引擎中進行試驗，研究過程分成實車性能與馬力試驗機性能試驗兩類，前者進行實車電池負載、點火波形影響與油耗表現實驗，後者於馬力試驗機上依循FTP-75與SFTP SC03兩種模式進行實驗，在控制的實驗條件下，以鉛酸電池之性能表現為基礎，比較鋰鐵電池在不同車速與轉速下，在電池負載、點火波形穩定度與油耗扭力、牽引力及廢氣排放物各種廢氣排放濃度與性能之變化。 研究實驗結果顯示：使用鋰鐵電池，在電池負載充放回充性能上較佳；點火波形穩定度高；實際路跑油耗平均下降2~5%；低轉速下的燃料消耗比率平均下降3.36~4.12%；各種轉速的廢氣排放比率CO降低2.8~20.6%、HC降低35.7~98.4%；NOX降低12.4~35.6%；整體有效馬力效率提高1.27~4.63%、輸出牽引力提高5.64~9.13%。因此於汽油引擎使用鋰鐵電池，除了本身使用壽命延長外，更可使汽油引擎提升節能效果，提高引擎馬力扭力的輸出，並降低排煙汙染物，有效達成節能減碳的目標。
