Matoorka Farogelinta vs. Matoorka Aan Faragelinta Lahayn: Matooradayda ma garaaceen bistoonada?¶

Su'aasha kaliya ee ugu muhiimsan makaaniknimada ka dib suunka waqtiga ama silsiladaha waqtiga ayaa ah in injiinkaagu yahay ** Engineer Faragelin *** ama ** Matoor Aan Farogelin (Free-Running) Matoorka ***:

1. Sida uu u shaqeeyo "Interference Engine" (>80% Baabuurta Casriga ah iyo 100% Matoorada Naaftada)¶

Si loo gaaro waxtarka shidaalka sare, saamiga cadaadiska sare, iyo heerarka qiiqa adag, ku dhawaad dhammaan afarta-dhululubo ee casriga ah, V6, V8, iyo **dhammaan matoorada naaftada *** waxaa loo qaabeeyey sida ** matoorada faragelinta *: - Hawlgalka caadiga ah, tuubada qaadashada ayaa hoos u fureysa xagga sare ee dhululubada inta uu piston-ku hoos u socdo, oo wuxuu xiraa millise seconds ka hor inta uusan pistonku dib ugu laaban ** Xarunta Dhimashada Sare (TDC) ** at ** 50 kacdoonnada ilbiriqsi kasta (3,000 RPM). - Marka suunka wakhtiga ama silsiladu is qabsado, ** kaamarooyinka ayaa isla markiiba joojiya wareegtada ***, taasoo ka tagaysa dhawr qaadasho iyo tubooyinka qiiqa barafoobay ** ballaaran oo furan *** ku dheggan qolalka gubanaya. - Dhanka kale, baabuurka cuslaa weli wuu sii rogmanayaa wadada weyn (ama wiishku wali wuxuu leeyahay firfircooni wareeg ah), oo ku qasbaysa **shaft-ga iyo bistoonada inay sii wadaan kor iyo hoosba daraasiin kacdoono ***. - Gudaha **0.1 ilbiriqsi ee ugu horeysa ee suunka wakhtiga dariiqa wayn, pistons-yada aluminiumka ah ee kor u kacaya waxay si toos ah ugu dhuftaan madaxyada birta furan ee wadada RPM: - ** Xaaladda Faragelinta ugu Fiican ***: Birta khafiifka ah ee afkoda 4 ilaa 16 qaadashada/qalabka daminta waxay ku foorarsadaan xagal 15-ilaa-30-degree ah (luminta dhammaan isku-buuqa si matoorku uusan u ordi karin), halka taajajyada piston-ka aluminiumka qaro weyni ay qabaan nikisyo qurxin qaabaysan oo yar yar. Ka saarida madaxa dhululubada, bedelida shalalka qaloocan iyo hagayaasha, iyo rakibida xirmo waqtiyeed cusub ayaa soo celinaysa mishiinka. - ** Muuqaalka Faragelinta Kiis-kii ugu xumaa ***: Madaxa waalka ayaa gabi ahaanba ka soo booday jirkiisa wuxuuna ku dhacayaa dhululubada, halkaas oo piston-ku uu kor ugu garaacayo sida anvil birta, isagoo dalool ku garaacaya taajka biistoonka aluminium, dildillaacaya gidaarka dhululubada, oo burburinaya dhammaan block engine.

2. Sida uu u shaqeeyo Matoorka "Faragelin La'aan (Free-Running)"¶

** Matoorka aan faragelinta lahayn ***, qolka gubashada si qoto dheer ayaa loo dejiyay (ama taajka piston waxay leeyihiin dhejis qoto dheer oo valve-relief) taas ** xitaa marka waalka uu ku dheggan yahay boqolkiiba 100 ballaaran oo piston uu gaaro meesha ugu sareysa ee istaroogga (Xarunta Dhimashada sare), weli waxaa jira 1 ilaa 3 millimitir oo farqiga hawada u dhexeeya piston: - Marka suunka wakhtigu uu ku dhejiyo mishiinka aan faragelinta lahayn ee 110 km / h (70 mph), matoorku si fudud ayuu u joojinayaa rasaasta oo wuxuu u leexiyaa garabka isagoo leh ** eber waalka gudaha ah ama dhaawaca piston ***. - Marka la jiido dukaan, makaanigu wuxuu ku dhejiyaa suunka cusub ee $50 iyo xirmada kicinta, wuxuu toosiyaa calaamadaha waqtiga, matoorku wuxuu u bilaabmayaa isla markiiba sidii iyadoo aan waxba dhicin.

Tixraaca Degdega ah: Faragelinta vs. Matoorada aan Farogelinta ahayn ee Samaynta¶

Xaqiijinta tillaabo-tallaabo-tallaabo: "Checkka Kaamshaft Koofida Saliidda 5-Labaad"¶

Marka si badbaado leh loo dhigo gadaasha dariiqa ilaalinta ee garabka oo shiduhu leeyahay OFF, waxaad xaqiijin kartaa in suunkaaga wakhtiga ama silsiladaagu uu ku dhacay wax ka yar 30 ilbiriqsi iyada oo aan wax qalab ah la helin:

1. ** Dabool daboolka oo hel Cap Filler Oil Engine *** korka daboolka matoorka (sida badan waxaa lagu calaamadiyaa saliid calaamad ama heerka viscosity sida 5W-30 ama 0W-20).
2. ** Fur fur furka saliidda oo toos toosh taleefankaaga casriga ah ugu iftiimi godka saliidda**:
3. Matoorada kamaradaha badan ee dusha sare ah, waxaad ku arki kartaa bir dhalaalaysa ** camshaft lobe ***, ** cudud dhagax ah **, ama ** silsilad waqti sare ah ** oo toos ah iyada oo loo marayo furitaanka buuxinta saliidda (haddii birtu ay xannibto aragtida, fiiri suunka wakhtiga caagga ah ee daboolka sare ee dhinaca rakaabka ee matoorka si aad u aragto haddii ay la furi karo cidhifka sare).
4. **Haddii Cam Lobe ama Silsilad La Muuqato ***: Rakaab ha fadhiisto kursiga darawalka oo taabo bilawga 0.5 ilbiriqsi kaliya intaad ka daawanayso daloolka buuxinta saliidda (faraha ku hay oo dhar dabacsan):
5. Haddii aad maqasho mootada bilawga ah oo ku wareegaysa shafka hoose (crankshaft)zzzzzz), laakin camshaft lobe ama silsiladda gudaha daloolka buuxinta saliidda waxay ahaanaysaa 100% dhaqdhaqaaq la'aan, suunkaga wakhtiga ama silsiladda wakhtigu waa la xaqiijiyay inuu jabay. Isla markiiba joojiya qulqulka oo wac gaadhi jiidh.

Ka digtoonow suunka "Waqtiga Qoyan" Saliida-Gaajo Cascade (Ford EcoBoost, PSA 1.2 PureTech, VW TDI)¶

Haddii aad kaxayso baabuur ku qalabaysan suunka waqtiga qoyan (Belt-in-Oil) *** - sida ** Ford 1.0L EcoBoost **, ** Ford 2.0L EcoBlue Diesel ***, ** Peugeot / Citroën / DS / Vauxhall / Opel 1.2L / Opel 1.2L / Opel 1.2L PureTechnda V. suunka waqti-gurid la'aanta waxay inta badan ku bilaabataa nalka digniinta khiyaanada ah ka hor inta uusan suunka dhab ahaantii dhicin:

1. ** Sida Suunka Qoyan u Hooseeyo ***: Sababtoo ah suunka wakhtiga caagga ah wuxuu ku dhex jiraa saliidda mishiinka kulul, iyadoo la adeegsanayo qeexida khaldan ee saliidda injiinka ama kordhinta saliidda waxay sababtaa caagga sare ee suunka inuu bararo oo u burburo jajabyo caag madow oo yaryar.
2. ** Iftiinka Cadaadiska Saliidda Cas & Digniinta Lugta Adag ee Biriiga ***: Jeexjeexyada suunka caagga ah waxay hoos ugu dhaadhacaan xagga hoose ee digsiga saliidda iyo ** xiro shaashadda mesh ee tuubada soo qaada bamka saliidda ** (iyo shaashadda bamka vacuum).
3. Maalmo ama daqiiqado ka hor inta suunka qoyan ee qoyan uu dhab ahaantii xajinayo, ** Iftiinka Digniinta Cadaadiska Saliida Matoorka Hoose ee Cas (saliid ayaa calaamadsan karta)** ayaa ku iftiimaysa dashboard-ka ** badhka biriigana wuu noqdaa mid adag *** (sababtoo ah bamka faakuumka gaajaysan ee saliidda ayaa joojiya samaynta faakuumka biriiga).
4. **Haddii aad aragto iftiinka Cadaadiska Saliidda Cas ama aad dareento badd bireega adag ee mishiinka suunka qoyan, jiid oo xidh mishiinka 30 ilbiriqsi gudahood *** - joogsiga ka hor inta suunka qoyan ee saliidda gaajaysan uu dillaacin ilkahiisa waxay ka badbaadinaysaa matoorka burburka musiibada ah ee valve-to-piston.

Lambarada degdega ah ee gobolka iyo borotokoolka wakaalada¶

Sababtoo ah suunka wakhtiga go'ay ama silsiladdu waxay sababtaa isla markiiba, wadarta luminta dhaqdhaqaaqa xawaaraha wadada weyn, ka bixida jidadka tooska ah iyo ka ilaalinta dadka degan shilalka danbe ayaa ah mudnaantaada ugu sareysa:

Su'aalaha soo noqnoqda¶

Muxuu badayga bireega u noqday mid adag isla markaaba matoorku ku dhintay jidka?¶

Bareegyada hadhidarooliga ee gaadhigaagu waxay adeegsadaan caasada xoojisay bireega faakuumka ee ku rakiban darbiga dabka kaas oo ku tiirsan nuugista faakuumka ee mishiinka socodka qaadasho badan (ama bamka faakuumka farsamaysan ee uu wado kamarada) si uu cadaadiska cagahaaga ugu dhufto 3 ilaa 4 jeer. Isla markiiba suunka wakhtigu soo dhaco oo matoorku istaago wareegtadii, faakuum cusub lama soo saarin, taasoo ka dhigaysa kaliya faakuum ku xayiran gudaha qasaca suunka 1 ilaa 2 cadaadis caadi ah. Marka aad riixdo oo aad sii deyso badeelada laba jeer, faakuumkaas kaydsan wuu baxay waana inaad ku riixdaa bistoonka haydarooliga ah ee aan la caawinin oo leh 50 ilaa 75 kiiloogaraam (110 ilaa 165 rodol) oo lug cayriin ah si aad u joojiso baabuurka.

Sideen ku ogaan karaa dhawaaqa bilawga in suunka wakhtigaygu jabay iyo in kale?¶

Samee hal ilbiriqsi oo dhageysi ah oo loo yaqaan "imtixaanka cadence bilowga." Caadi ahaan, marka aad matoorka ku rujiso, mishiinka bilawga ahi waxa uu samaynayaa xamaasad, isaga oo garaaca "uh-uh-uh-uh" dhawaaqa marka uu mid kasta oo soo kacaya piston uu la dagaallamo 150 PSI ee cadaadiska hawada ku xayiran gudaha dhululubada. Marka suunka wakhtiga ama silsiladdu jabo, kaamirooyinka ayaa joojinaya dhaqaaqa waxayna ka tagaan furayaasha furnaadaan, iyaga oo meesha ka saaraya isku-buufinta dhululubada; Natiijo ahaan, mishiinka bilawga ahi wuxuu labanlaab ka dheereeyaa sida caadiga ah oo leh dhawaaq sare, gebi ahaanba siman, dhawaaq koronto la'aan ah ("zzzzzzzz") sida mashiinka dharka ama laydhka korontada.

Haddii mishiinka faragelintaygu uu suunka wakhtiga ku dhufto 100 km/h (60 mph), ma dammaanad qaaday matoorku in la isku geyn doono?¶

Had iyo jeer maaha - halka qaar ka mid ah valves ay dhab ahaantii foorarsan yihiin marka suunka wakhtigu uu ku dhejiyo mashiinka faragelinta ee xawaaraha wadada, dhammaadka hoose ee mishiinka (mashiinka mashiinka, crankshaft, ulaha isku xirka, iyo pistons) ayaa si sax ah u noolaada qiyaastii 60 ilaa 70 boqolkiiba kiisaska la siiyay darawalku si dhakhso ah ayuu u wareegay dhexdhexaad oo ma sii wadin garbaha garabka bilawga ah. Makaanigu waxa uu 15 daqiiqo ku baari karaa dushooda bistoonada isaga oo isticmaalaya kamarad borescope fiber-optic oo la geliyo godadka dhimbiilleyda; Haddi aanu madaxa waalka ka bixin oo daloolin taajka bistoonka, ka saarida madaxa silinada iyo bedelida valves-qaloocan iyo xidhmada suunka wakhtiga ayaa inta badan ka qaalisan bedelida mishiinka oo dhan.

Muxuu suunka wakhtigaygu u jabay inkasta oo gaadhigaygu uu kaliya 55,000 mayl (88,000 km) dul saaran yahay mitirka?¶

Muddada beddelka suunka waxaa had iyo jeer lagu qeexaa masaafada iyo waqtiga labadaba - caadi ahaan 60,000 ilaa 100,000 mayl (95,000 ilaa 160,000 km) AMA 7 ilaa 10 sano, hadba kii soo hormara. Xitaa haddii baabuur lagu wado 5,000 mayl sannadkii, suunka wakhtiga caagga ah ee 12-jirka ah wuxuu maraa kumanaan wareegyo kulayl-kuleyl ah oo kulul iyo ozone oxidation kuwaas oo qallajiya caagga synthetic ilaa ay ilkuhu ka xiiraan, ama dufanka gudaha bamka biyaha ama xajinta xajinta ayaa qallajisa oo qabta jilbaha.

Matoorada leh silsiladaha waqtiyada biraha weligood miyay u jajabaan sida suumanka wakhtiga caagga ah?¶

Haa Inkasta oo silsiladaha wakhtiga birta ahi aanay ka qudhmin da'da sida suumanka caagga ah, waxay ku tiirsan yihiin saliidda mishiinka la cadaadisay si ay u saliideeyaan boqollaal biin bir ah oo yaryar oo ay cadaadis ku saaraan silsiladaha silsiladaha haydarooliga ee ka soo horjeeda hagayaasha silsiladaha caagga ah ee qaloocan. Haddii isbeddellada saliiddu ay aad u dheer yihiin, haddii mishiinka uu ku hooseeyo saliidda, ama haddii silsiladda balaastigga ah ee jajaban ay dillaacdo 100,000 mayl ka dib, silsiladdu way fidsan tahay, kor u kacdaa subaxda qabow, waxay ku booddaa sprockets camshaft, ama waxay si buuxda u dhufataa isla saxan isku mid ah valve-to-piston dhaawaca sida suunka wakhtiga jabay.
