In the past, the engine break-in period was very important to the overall
life and durability or the engine.
The break-in period required has changed over the years with improved piston
ring materials and designs.
The break-in period now (5-10 hours) is short in comparison with that
of engines of the past.
Aluminum cylinder bore engine piston rings break-in faster than those
used on cast iron cylinder bores.
以前磨合期比較長,現在磨合期合比較短(5-10小時),鋁合金汽缸磨合較快
不過要不要大操...老外也在戰,目前沒結論,但有共通點
1.不要急拉轉,有的說1500rpm就好,有的說至少4500rpm
但兩方都同意不要一下就大油門拉轉,緩緩拉上去
2.現在汽車生產製程跟材料的改變使得磨合期程序也有變化
3.的確有磨合期這種東西,有些要求高的磨合完還要再重新鎖緊
4.到底要怎麼磨合還是沒定論,各車種各組件磨合程序也不一樣
