外媒分析小排氣量渦輪與大排氣量自然進氣引擎可靠性

外媒《Carbuzz》針對小排氣量渦輪引擎與大排氣量自然進氣引擎進行可靠性分析,發現小排氣量渦輪投訴數據明顯較多。

Quick Look

外媒《Carbuzz》分析指出,由於承受更高工作壓力與零件較多,小排氣量渦輪引擎的投訴數據與故障機率明顯高於大排氣量自然進氣引擎。

Why It Matters

全球車市近年普遍採取 Downsizing 策略,以小排氣量渦輪引擎取代大排氣量自然進氣引擎。

如今全球車市普遍都採取 Downsizing 策略,以小排氣量渦輪引擎取代過往大排氣量自然進氣引擎,但《Carbuzz》近期針對兩種引擎進行可靠性分析,發現兩者在機械結構與工作環境上存在明顯差異,而事實上小排氣量渦輪的投訴數據明顯比較多。

小排氣量渦輪更高機率出現問題。

大排氣量自然進氣引擎耐用度更佳。

根據《Carbuzz》的分析,小排氣量渦輪引擎要做到媲美大排氣量引擎的動力輸出,主要是利用排出的廢氣推動渦輪,透過壓縮機將更多空氣注入燃燒室,讓燃燒室得以噴入更多燃油並產生更大動力,而一具 1.5 升渦輪引擎需要承受更高燃燒壓力與熱負荷,才能媲美一般 2.0 升或 2.5 升自然進氣引擎動力。

同時《Carbuzz》點出,小排氣量渦輪的活塞、連桿、汽缸壁、冷卻系統都要承受更高的工作壓力,同時渦輪系統還意味著有渦輪本體、軸承、進氣管路等更多相應零件,當零件越多也就意味著會出問題的環節越多,因此普遍大排氣量自然進氣引擎都更為耐用。

不過這不意味著小排氣量渦輪就一定容易壞,主要還是取決於多方面因素,包括原廠是否從一開始就為引擎設定高負荷的活塞、連桿、汽缸與冷卻系統,若是後來純粹追求高輸出的設定在耐久性上勢必較弱。

另外渦輪引擎更依賴機油進行潤滑散熱,因此機油品質、正確黏度與更換週期都更為重要,長期延遲更換勢必會增加受損風險,另外駕駛的使用方式也須注意,若在引擎尚未達到正常工作溫度時經常暴力駕駛也會增加零件磨損。
