style="text-indent:25px">噴油嘴：噴油嘴其實(shí)就是個(gè)簡(jiǎn)單的電磁閥,當(dāng)電磁線圈通電時(shí)，產(chǎn)生吸力，針閥被吸起，打開噴孔，燃油經(jīng)針閥頭部的軸針與噴孔之間的環(huán)形間隙高速噴出，形成霧狀，利于燃燒充分。噴油嘴本身是一個(gè)常閉閥，當(dāng)ECU下達(dá)噴油指令時(shí)，其電壓訊號(hào)會(huì)使電流流經(jīng)噴油嘴內(nèi)的線圈，產(chǎn)生磁場(chǎng)來把閥針吸起，讓閥門開啟好使油料能自噴油孔噴出。噴射供油的較大優(yōu)點(diǎn)就是燃油供給之控制十分精確，讓引擎在任何狀態(tài)下都能有正確的空燃比，不光讓引擎保持運(yùn)轉(zhuǎn)順暢，其廢氣也能合乎環(huán)保法規(guī)的規(guī)范。4升汽油機(jī)采用鋁合金缸體，取得了十分明顯的輕量化效果。</p><div

style="text-indent:25px">油分分離器設(shè)計(jì)理念：1、重力沉降法：氣流在分離器內(nèi)的流動(dòng)過程中只要作用于液滴上重力大于氣流作用于液滴上的阻力，液滴就會(huì)從氣相中沉降出來。只能除去直徑為100微米以上的液滴，保證不了分離效果，必須與其它分離方法配合同時(shí)應(yīng)用才能得以保證，主要適用于沉降段。2、離心分離法：當(dāng)液體改變流向時(shí)，密度較大的液滴具有較大的慣性，就會(huì)與器壁相撞，使液滴從氣流中分離出來，這就是離心分離，主要適用于初分離段。3、碰撞分離法：氣流通過障礙改變流向和速度使氣體中的液滴不斷在障礙面內(nèi)聚結(jié)，由于液滴表面張力的作用形成油膜。氣流在不斷地接觸中，將氣體中的細(xì)油滴，聚結(jié)成大油滴靠重力沉降下來，主要適用于油煙。濟(jì)南汽車配件交易網(wǎng)</p><p
