氣門挺桿簡介

氣門挺桿。氣門挺桿的作用如下：

1、為了保證氣門關閉嚴密，會在氣門桿端與氣門驅動件之間留有適當的間隙，稱為氣門間隙；

2、若氣門間隙調整不當就會使發動機運行不正常的，過大會影響氣門的開啟量，氣門升程減少引起進氣不足，排氣不徹底，過小會引起氣門關閉不嚴引起漏氣，造成動力下降；

3、所以為了避免氣門間隙調整不當引起的麻煩，一般高速發動機上都會使用可自行調整氣門間隙的液力挺桿。

寶馬530Li簡介

寶馬530LI是寶馬5系的車型之一，寶馬530LI作為華晨寶馬5系的加長版，可以說在外觀上完全繼承了寶馬5系的所有基因。
張揚的鷹眼大燈是它最吸引人的地方，全身上下鋼勁有力的線條從視覺上就讓人有駕馭它的沖動。加長后修長的車身看上去更加莊重了一些，增加了一絲公務用車的穩重感。
