Pawiri pamwamba camshaft: kufotokoza

Mawu amenewo omwe aliyense adawamvapo kale ndi camshaft yotchuka yapawiri. Mawu omwe amadziwikanso kuti "ma valve 16" koma omwe anthu ambiri (ndipo zili bwino) sadziwa kwenikweni tanthauzo lake ... Choncho tiyeni tiyende pang'ono pa dongosolo la shaft. Ndi mbiri ya cam kuti muthe chikhalidwe chagalimoto yanu.

Camshaft?

Mu kasinthasintha kasinthasintha ndi crankshaft (malumikizidwe amachitika ndi kugawa), camshaft imagwira ntchito ngati mavavu olowera (kumene mpweya + mafuta amalowa) ndi ma valve otulutsa (kumene mpweya umapita).

Apa pali injini ndi

chimodzi chokha

camshaft

Apa tikuwona pafupi ndi makamera omwe amakankhira ma valve pansi, kuchititsa kutsegula m'chipinda choyaka moto (mwina pakumwa kapena kutulutsa).

Mwachitsanzo, pa injini ya 4-cylinder in-line (zonse zomwe zimagwira ntchito ku France) camshaft imodzi ndi yokwanira kulamulira ma valve awiri pa silinda.

Nthawi zambiri, injini "zachikale" zimagwiritsa ntchito pulley imodzi yokha (LIGHT green). Pano pa injini ya Mazda iyi, tikutha kuona kuti pali awiri. Izi zikuwonetsa kuti ma camshaft awiriwa ali ndi makanema.

Kuchokera kumbali ina iyi (kuyenda kumanzere) tikhoza kuwona mwachidule chimodzi mwazo два camshafts (mu pinki).

Chachiwiri sichikuwoneka

chifukwa "yadulidwa" kuti muwone mkati mwa injini (ngakhale mutha kuwona dzenje lomwe likulowamo, yang'anani). Chobiriwira chakuda ndi crankshaft, buluu ndi imodzi mwa mavavu, ndipo chofiira ndi chingwe cha nthawi. Zindikirani kuti timangowona ma valve otulutsa mpweya pano chifukwa ena onse adachotsedwa chifukwa chofanana ndi camshaft yachiwiri.

Pawiri? Kodi ubwino wake ndi wotani?

Mudzamvetsetsa kuti camshaft iwiri imakhala ndi ziwiri m'malo mwa imodzi. Ndipo nayi maubwino aukadaulo awa:

• Pali ma valve ambiri, omwe amalola injini kupuma bwino.
• Zimango zamtunduwu ndizoyeneranso kuthamanga kwambiri, zomwe ndi zabwino kwa injini zogwira ntchito kwambiri (makamaka mafuta amafuta, chifukwa mafuta amadzimadzi samafika ma rpms apamwamba).
• Kukonzekera kumeneku kumapangitsa kupanga injini kukhala kosavuta kwa mainjiniya (kapangidwe kagawidwe, malo opangira ma spark plugs, ndi zina zambiri, chifukwa m'malo mokhala pamwamba pakati, imodzi mbali iliyonse)

Ambiri, mapasa kutsinde injini adzakhala 4 mavavu pa yamphamvu (nthawi zambiri awiri, mwachitsanzo 8 mavavu pa masilindala 4, chifukwa 4 X 2 = 8 ...), koma izi si zofunika.

Koma samalani! V6 kapena V8 yokhala ndi ma camshaft awiri samatengedwa ngati camshaft yapawiri. Kuti muchite izi, payenera kukhala masilindala awiri pamzere uliwonse wa masilinda.
