I-camshaft engaphezulu ephindwe kabili: incazelo

Leyo nkulumo wonke umuntu ake wayizwa ngaphambili iyi-camshaft engaphezulu ephindwe kabili edumile. Inkulumo eyaziwa nangokuthi "ama-valve angu-16" kodwa abantu abaningi (futhi kulungile) abangazi ngempela ukuthi isho ukuthini... Ngakho-ke ake sithathe uhambo oluncane lwalesi simiso se-shaft. Ngomlando we-cam ukuze wenze isiko lemoto yakho.

I-Camshaft?

Lapho uzungezisa ngokuhambisana ne-crankshaft (ukuvumelanisa kwenziwa ngokusatshalaliswa), i-camshaft isebenza njengama-valve okungenisa (lapho kungena khona umoya + uphethiloli) kanye nama-valve okukhipha (lapho amagesi aya khona).

Nansi injini nge

eyodwa kuphela

camshaft

Lapha sibona eduze kwamakhamera aphushela ama-valve phansi, abangele ukuvuleka ekamelweni elivuthayo (kungaba ekungeneni noma ekukhishweni).

Isibonelo, ngenjini engu-4-cylinder in-line (iningi kakhulu yonke into esebenza eFrance), i-camshaft eyodwa yanele ukulawula ama-valve amabili isilinda.

Ngokuvamile, izinjini "zakudala" zisebenzisa i-pulley eyodwa kuphela (Light green). Lapha kule njini yakwaMazda, siyabona ukuthi zimbili. Lokhu kubonisa ukuthi ama-camshafts amabili ayagqwayiza.

Kusukela kule enye i-engeli (ukunyakaza ukuya kwesobunxele) singabona kafushane enye ye два ama-camshafts (epinki).

Eyesibili ayibonakali

ngoba "isikiwe" ukuze ukwazi ukubona ingaphakathi lenjini (noma kunjalo ungabona imbobo engena kuyo, bheka). Okuluhlaza okumnyama yi-crankshaft, okuluhlaza okwesibhakabhaka kungenye yamavalvu, futhi okubomvu uchungechunge lwesikhathi. Qaphela ukuthi sibona kuphela ama-valve okukhipha amanzi lapha ngoba amanye akhishwe ngesizathu esifanayo nesesibili se-camshaft.

Kukabili? Yiziphi izinzuzo?

Uzoqonda ukuthi i-camshaft ephindwe kabili inamabili esikhundleni seyodwa. Futhi nazi izinzuzo zalesi sixazululo sobuchwepheshe:

• Kukhona ama-valve amaningi, okwenza injini iphefumule kangcono.
• Lolu hlobo lwemishini lufaneleka kangcono isivinini esikhulu, esilungele izinjini ezisebenza kakhulu (ikakhulukazi uphethiloli, ngoba uphethiloli owuketshezi awufinyeleli kuma-rpms aphezulu).
• Leli lungiselelo lenza ukwakheka kwenjini kube lula konjiniyela (umklamo wokusabalalisa, isikhala samapulagi amakhulu ezinhlansi, njll., ngoba esikhundleni sokuba phezulu phakathi, eyodwa ohlangothini ngalunye)

Ngokuvamile, i-twin shaft injini izoba nama-valve angu-4 nge-cylinder ngayinye (imvamisa amabili, okungukuthi ama-valve angu-8 ngamasilinda angu-4, ngoba 4 X 2 = 8 ...), kodwa lokhu akudingekile.

Kodwa qaphela! I-V6 noma i-V8 enama-camshaft amabili ayithathwa njenge-double overhead camshaft. Ukuze wenze lokhu, kufanele kube namasilinda amabili emgqeni ngamunye wamasilinda.
