技術(shù)師專業(yè)介紹SMC氣缸的工作原理,我公司專業(yè)工程師按常規(guī)方式對日本SMC氣缸進(jìn)行產(chǎn)品簡單的原理介紹,發(fā)動(dòng)機(jī)內(nèi)的圓筒形空室,里面有一個(gè)由工作流體的壓力或膨脹力推動(dòng)的活塞,某些特殊型發(fā)動(dòng)機(jī)內(nèi)的類似的、但非圓筒形的部分 發(fā)動(dòng)機(jī)內(nèi)的圓筒形空室,里面有一個(gè)由工作流體的壓力或膨脹力推動(dòng)的活塞,某些特殊型發(fā)動(dòng)機(jī)內(nèi)的類似的、但非圓筒形的部分。一般來說,同等排量情況下,氣門越多,進(jìn)排氣效率越好,就像一個(gè)人跑步,累得氣喘吁吁時(shí),需要張大嘴巴呼吸。傳統(tǒng)的發(fā)動(dòng)機(jī)多是每缸一個(gè)進(jìn)氣門和一個(gè)排氣門,這種二氣門配氣機(jī)構(gòu)相對比較簡單,制造成本低,維修起來也相對容易。對于輸出功率要求不太高的普通發(fā)動(dòng)機(jī)來說,兩氣門就能獲得較為滿意的發(fā)動(dòng)機(jī)輸出功率與扭矩性能排量較大、功率較大的發(fā)動(dòng)機(jī)要采用多氣門技術(shù)。
日本SMC氣缸zui簡單的多氣門技術(shù)是三氣門結(jié)構(gòu),即在一進(jìn)一排的二氣門結(jié)構(gòu)基礎(chǔ)上再加上一個(gè)進(jìn)氣門。近年來,世界各大汽車公司新開發(fā)的轎車大多采用四氣門結(jié)構(gòu)。四氣門配氣機(jī)構(gòu)中,每個(gè)氣缸各有兩個(gè)進(jìn)氣門和兩個(gè)排氣門。四氣門結(jié)構(gòu)能大幅度提高發(fā)動(dòng)機(jī)的吸氣、排氣效率,新款轎車大都采用四氣門技術(shù)。當(dāng)然,大眾汽車多采用五氣門技術(shù),如老款捷達(dá)王的20V發(fā)動(dòng)機(jī),寶來1.8T發(fā)動(dòng)機(jī)也是五氣門。不過,達(dá)到或超過六氣門不僅使配氣結(jié)構(gòu)過于復(fù)雜,還會(huì)導(dǎo)致發(fā)動(dòng)機(jī)壽命縮短,氣門開啟的空間簾區(qū)(氣門的圓周和氣門的升程)也較小,效率下降。因此,四氣門技術(shù)目前使用zui為普遍。需要指出的是,汽缸和氣門數(shù)可以作為判斷發(fā)動(dòng)機(jī)優(yōu)劣的標(biāo)準(zhǔn)之一,但不是*標(biāo)準(zhǔn)。比如,寶馬公司的直列4缸2.0升發(fā)動(dòng)機(jī),由于其*的可變氣門技術(shù),在功率和扭矩輸出上絲毫不遜于普通的6缸機(jī),這也是寶馬318轎車動(dòng)力性*的原因。奔馳公司長期采用每缸3氣門技術(shù),也達(dá)到了很好的功率、扭矩和環(huán)保水平。此外,配備渦輪增壓技術(shù)后,寶來1.8T4缸機(jī)的功率和扭矩也能達(dá)到普通6缸機(jī)的水平。
