Madaxa Silinder

Madaxa Sylinder Flathead
Bal qiyaas in aad dib ugu soo noqonayso wakhtiyadii hore ee baabuurta. Ford Model T, oo ah astaanta adduunka baabuurta, ayaa leh madax dhululubo ah oo fidsan. Noocan madaxa dhululubada waxaa lagu gartaa fududaantiisa iyo, sida magacu muujinayo, naqshad siman. Matoorka fidsan dhexdiisa, waxa aad ogaan doontaa in faashaduhu ay ku yaalliin qaybta matoorka iyada oo ka soo horjeeda madaxa dhululubada, taas oo keentay naqshad toos ah.

Madaxa Dabaqaha ee Valve (OHV).
Markii ay baabuurtu noqdeen kuwo aad u casrisan oo ay dalbadeen koror koronto iyo hufnaan, madaxa galka sare (OHV) ee dhululubada ayaa u soo baxay sidii ciyaar{0}} beddele. Naqshadaynta OHV, valves-yadu waxay si toos ah u taagan yihiin meel ka sarreysa dhululubada, gudaha madaxa dhululubada. Habayntani waxa ay awood u siinaysaa in si fiican loo xakameeyo wakhtiga waalka iyo hawlgalka, taas oo u horseedaysa hufnaanta matoorka iyo hufnaanta shidaalka oo la xoojiyay.

Madaxa Dabaqaha ee Camshaft (OHC)
Si loo helo hufnaan iyo waxqabad ka sii weyn, injineeradu waxay soo bandhigeen madaxa camshaft (OHC) ee dhululubada. Si ka duwan sida naqshadaha OHV, madaxyada dhululubada OHC waxay dejiyaan kamarad kaamirada madaxa dhululubada lafteeda, iyaga oo si toos ah u shaqaynaya valves. Habayntani waxa ay ogolanaysaa in la xakameeyo waalka saxda ah iyo wakhtiga, taas oo keenaysa in mishiinku si fudud u shaqeeyo iyo hufnaanta shidaalka oo la hagaajiyo.

Hemispherical (Hemi) Madaxa Dabaqaha
Erayga Hemi waxa uu la mid noqday matoorada waxqabadka sare-, taas oo ay ugu mahad naqayso matoorada geesiga ah ee Hemi ee uu soo saaray Chrysler. Madaxda Hemi cylinder waxay leeyihiin qaab hemispherical oo kala duwan, oo leh alwaaxyo xagal taagan, oo u eeg kala bar{2}}.

Madaxa Baasaboorkii Valve
Iyadoo madaxa dhululubada rotary valve uusan u badnayn sida noocyada kale, waxaa mudan in la xuso habka gaarka ah ee loo maareeyo socodka hawada. Naqshadeynta waalka rotary, halkii ay ka ahaan lahaayeen valves poppet dhaqameed, valves rotary ayaa loo isticmaalaa si loo xakameeyo qaadashada iyo gaaska qiiqa. Furayaashani waxay u wareegaan inay furaan oo xidhaan dekedaha, iyaga oo xakameynaya socodka hawada iyo qulqulka qiiqa.

Multi- Madaxa Baasilaha Valve
Iyada oo la raadinayo in wiish kasta oo koronto ah laga tuujiyo matoorka, injineeradu waxay u jeesteen naqshada madaxa silsilada badan ee - Si ka duwan sida labada dhaqameed ee - nashqadaha waalka, kuwa badan{3}} madaxyada dhululubada waalka ah waxay ka kooban yihiin saddex, afar, ama xataa shan valves per cylinder, taasoo ku xidhan qaabaynta.

Pentroof Sylinder Head
Madaxa dhululubada pentroof ayaa magaciisa ka helay qaabkiisa, kaas oo u eg saqafka kore ee guriga. Nashqadan waxaa badanaa lagu arkaa khadka -afar{2}} matoorada dhululubo, halkaasoo boosku xadidan yahay. Naqshadeynta pentroof waxay u oggolaaneysaa naqshad is haysta oo haddana hufan ee valfadaha iyo dhinbiyadaha.

Madaxa Dabaqadda Sare ee Camshaft (DOHC)
Iyada oo laga duulayo faa'iidooyinka naqshadda OHC, madaxa labajibbaara ee camshaft (DOHC) ee dhululubada wuxuu qaadaa saxnaanta iyo waxqabadka heerka xiga. Qaabaynta DOHC, waxaad ka heli doontaa laba kamarado, oo mid u go'ay inuu xakameeyo valves qaadashada iyo kan kale oo keligii mas'uul ka ah maaraynta valves qiiqa. Kaamirooyinkaani waxay u shaqeeyaan si madax banaan, iyagoo u oggolaanaya kontoroolka waalka saxda ah iyo hagaajinta waqtiga. Tani waxay u oggolaaneysaa xitaa waqti sax ah oo waalka iyo xakamaynta.
