不好意思,不懂車子原理...
已經爬文也搜尋過網路資料
還是想請教基本觀念,關於轉速&扭力的問題
=== 定義 ===
馬力: 引擎總輸出功率(kW or ps)
扭力: 活塞運動的出力矩, 驅動力矩(kg*m)
轉速: 活塞推動曲軸的轉速(rpm)
(先只探討引擎,不考慮齒比造成輪胎的扭力與轉速改變)
=== 問題 ===
(1) 轉速初期(低轉速時)會受扭力影響嗎?
我的想法是活塞扭力越大,帶動曲軸越快旋轉一圈,所以轉速快
這樣有錯嗎?
(2) 那轉速後期(高轉速時)不受扭力影響? 是受點火次數影響?
但這樣又跟問題(1)矛盾?
(3) 如果問題(1)是對的,
"車子起步時靠大扭力帶動轉速,才有大馬力加速"
這敘述是對的嗎?
(4) 怎麼解釋扭力與轉速的關係?
一般而言,轉速低~中~高, 扭力上升~飽和~下降
有查到高轉速扭力下降原因 (1)凸輪軸限制?! (2)燃燒效率下降?!
總結來說,搞不懂轉速被什麼影響,也不懂扭力與轉速的關係(雞與蛋?!)
謝謝大大的解惑...很低端的問題..
