Nissan cd20, cd20e, cd20et iyo cd20eti matoorada
Tusmo
Matoorada ay samaysay Nissan ayaa had iyo jeer ahaa kuwo tayadoodu aad u sarrayso, taas oo ka dhigaysa inay caan ku yihiin wadayaasha.
Dabcan, matoorada taxanaha cd20 sidoo kale lagama joojin dareenka. Waxaa intaa dheer, waxaa lagu rakibay noocyo badan oo baabuurta caanka ah.
Sharaxaadda mishiinka
Qaybtan korontadu waxay soo saartay 1990 ilaa 2000. Inta lagu jiro wakhtigan ayaa la casriyeeyay dhowr jeer. Natiijo ahaan, qoys dhan oo matoorada ah oo leh waxqabad la mid ah ayaa u muuqday. Dhammaan matoorada waxaa lagu kala soocaa kalsooni sare oo caddaalad ah, laakiin isla mar ahaantaana waxay qabaan cudurro caadi ah.
Matoorka ayaa hal mar la soo saaray dhowr shirkadood oo qeyb ka ahaa Nissan-ta xilligaasi. Tani waxay suurtogal ka dhigtay in la wanaajiyo habka wax soo saarka matoorada, si dhab ah u wareejinta goobta shirka ee moodooyinka gaarka ah ee baabuurta astaantan. Sidoo kale, qaar ka mid ah ganacsiyada ka baxsan walaaca waxay soo saareen cd20 qandaraas.
Matoor ayaa la abuuray iyadoo isha lagu hayo khadadka cusub ee baabuurta rakaabka ee Nissan ay markaasi soo bandhigtay. Sidaa darteed, injineeradu waxay isku dayeen inay ka dhigaan unugga mid la mid ah intii suurtagal ah. Guud ahaan, way ku guulaysteen.
Технические характеристики
Dhammaan mishiinnada gubashada gudaha ee taxanahan waxay ku shaqeeyaan shidaalka naaftada, siday u kala horreeyaan, waa sida saxda ah xaaladdan oo hubinaysa waxtarka mishiinka. Waxaa sidoo kale mudan in la tixgeliyo in, inkastoo naqshadda guud, dhammaan unugyada awoodda ee ka soo jeeda cd20 ay leeyihiin kala duwanaansho farsamo oo waxoogaa hagaajinaysa mashiinka asalka ah. Xogta guud ee farsamada ayaa laga heli karaa shaxda.

Fadlan ogow in matoorka noocyadiisa kala duwan uu yeelan karo astaamo kala duwan. Tusaale ahaan, sd20 waxaa laga yaabaa inay leedahay qiimeyn koronto oo kala duwan, waxay kuxirantahay goobaha matoorka ee noocyada kala duwan. Isticmaalka shidaalka ayaa sidoo kale laga yaabaa inuu isbedelo.
In kasta oo xaqiiqda ah in hadda mishiinka loo tixgeliyo qayb la isticmaali karo, waxaa fiican in la hubiyo nambarkiisa. Tani waxay ka fogaan doontaa dhibaatooyin badan, gaar ahaan haddii baabuurka ama mishiinka la iibsaday uu yeelan doono rikoor dembi. Waxaa jira saxan ay lambar ku daabacan tahay oo ku hoos jirta manifoldka hortiisa ee block-ka dhululubada, waxaad ka arki kartaa sawirka.
Isku halaynta baabuurta
Tayada matoorada Nissan ayaa guud ahaan la aqoonsan yahay. Habkani maaha mid ka reeban. Celceliska kheyraadka matoorka, kaas oo dammaanad qaadaysa soo saaraha, wuxuu u dhexeeyaa 250-300 kun kiiloomitir. Ficil ahaan, waxaa jira warshado koronto oo si aamusnaan leh u taga 400 kun, isla mar ahaantaana ma qorsheynayaan inay jebiyaan.
Sida caadiga ah, dayactirka ayaa loo baahan yahay marka matoorka aan la daryeelin. Xaaladdan oo kale, dhibaatooyin ayaa soo bixi doona xitaa tayada ugu sareysa iyo kuwa ugu kalsoonida badan.
Dayactirka saxda ah, xirashada dabiiciga ah ayaa ah khatarta ugu weyn waxaana la yareeyn karaa iyadoo la hubinayo in saliidda matoorka la beddelo waqtigeeda.
Maadaama uu yahay matoorka naaftada, sidaas darteed aad ayuu ugu adkaysanayaa culaysyada muddada dheer. Sidaa darteed, mishiinnada taxanahan ayaa u muuqday kuwo aad u faa'iido leh gawaarida saldhigyada, kuwaas oo loo isticmaali jiray in lagu qaado alaabo kala duwan.
Daryeelka
Aynu falanqeyno sifooyinka ugu muhiimsan ee dayactirka mashiinkan. Inta lagu jiro hawlgalka, inkastoo dib u eegis wanaagsan, waxaa laga yaabaa inay lagama maarmaan noqoto in la beddelo qaybo ka mid ah. Tani waa hab caadi ah.
Inta badan, qofku waa inuu wajaho baahida loo qabo beddelka wadista wakhtiga, suunka waxay u adeegaan celcelis ahaan 50-60 kun kiiloomitir. Qiimaha shaqadani waa mid hooseeya, laakiin waxay kaa badbaadin doontaa inaad dib u habeyn ku sameyso mishiinka.
Waa inaad sidoo kale si taxadar leh u eegtaa tayada shidaalka. Bamka duritaanka cd20 uma dulqaadan karo shidaalka wasakhaysan si aad u wanaagsan wuuna fashilmi karaa.
Markaad rakibayso bam cusub, hubi in calaamaduhu iswaafaqayaan. Meel 100000 kiiloomitir ah waxaad u baahan doontaa inaad bedesho bamka shidaalka. Waxa kale oo laga yaabaa inay lagama maarmaan noqoto in si joogto ah loo nadiifiyo sanbabada.
Madaxa ICE wuxuu kaloo keeni karaa dhibaatooyin. Gaskat-ka hoostiisa madaxa dhululubada ee xaaladaha qaarkood ayaa gubi kara, laakiin ma adka in la beddelo. Waxa kale oo laga yaabaa inay lagama maarmaan noqoto in lagu rakibo baaritaanka lambda cd20e, way fiicantahay in la isticmaalo qayb ka mid ah Japan. Wareegga ka-hortagga barafka ayaa sidoo kale laga yaabaa inuu qaso.
Shidaalku kuma qaldami karo cd20eti, naaftada ma laha. Sababta ayaa ah cadaadis hoose ama wareeg waqti ku guuldareystay. Mararka qaarkood way ku filan tahay oo kaliya in la hagaajiyo wakhtiga, waxaa habboon in la hubiyo in giraangiraha piston-ka ay hagaagsan yihiin, haddii ay ku dheggan yihiin, dib u habeyn weyn ayaa loo baahan yahay. Isla mar ahaantaana, cd20et waa lagama maarmaan in la beddelo crankshaft, maadaama aysan jirin cabbir dayactir ah. Xaaladaha qaarkood, way fududahay inaad iibsato mishiinka qandaraaska. Bilawga mishiinka waxaa laga yaabaa inuu saameeyo nidaamka kuleyliyaha hawada.
Matoorkaan waxaa laga yaabaa in uu dhibaato kala kulmo xirmooyinka. Bilawga inta badan wuu ku guuldareystaa, ama halkii bendix si dhakhso ah u daataan, waa ku filan oo kaliya in la beddelo. Mid kale oo ka mid ah lifaaqyada ayaa laga yaabaa inay fashilmaan bamka. Waxaa lagu talinayaa in marka lagu daro qalabka elektarooniga ah, koronto-dhaliye 20-amp cd90 ah lagu rakibo baabuurka.
Fiiro gaar ah waa in la siiyaa gudbinta. Buug-tilmaameedka ayaa sheegaya in qalliin aan sax ahayn uu keeni karo cillad. Xaaladdan oo kale, way fiicantahay inaad iibsato xirmo dhamaystiran oo xirmo ah. Buuggu waxa kale oo uu ku talinayaa in la beddelo saliidaha ku jira gudbinta tooska ah 40 kun kiiloomitir kasta.
Noocee saliid ah oo lagu shubo
Waxaad u baahan tahay inaad fahamto inay muhiim tahay in la doorto saliidda saxda ah. Matooradani waa kuwo aan fasiraad lahayn, sidaas darteed ku dhawaad wax kasta oo sub-synthetic ah iyo saliidaha mootooyinka synthetic ayaa la isticmaali karaa. Tixgeli viscosity, waxaa lagu doortaa iyadoo lagu saleynayo xilliga. U hubso inaad ilaaliso heerka ugu hooseeya ee saliidda lagu daboolay mar kasta.
Waa in la fahamsan yahay in beddel kasta, la rakibo shaandhada cusub ee saliidda. Haddii kale, waxaa jiri doona dhibaato xagga mishiinka.
Maxaa baabuur lagu rakibay
Matoorada waxaa lagu rakibay moodooyinka baabuurta caanka ah, sidoo kale waxaa laga heli karaa ciyaaraha taxanaha MTA. Waxaa markii ugu horreysay lagu arkay Nissan Avenir, kaas oo soo baxayay ilaa May 1990.
Mustaqbalka, mishiinka ayaa lagu rakibay moodooyinka sida Bluebird, Serena, Sunny, Largo, Pulsar. Waxaa intaa dheer, qaar ka mid ah, wax ka beddelka mishiinka ayaa lagu rakibi karaa laba qarni. Maaddaama rajada matoorada ay tahay mid aad u xoog badan, waxaa lagu rakibi karaa gawaarida ganacsiga ee Largo sida midka ugu weyn.
Qaabkii ugu dambeeyay ee cd20et si weyn loogu rakibay wuxuu ahaa jiilkii labaad ee Nissan Avenir. Baabuurtan waxa ay ku rakiban yihiin mishiin la mid ah ilaa April 2000.
