Izinjini ze-NA20P ne-NA20S Nissan
Okuqukethwe
Kuwo wonke umlando wabo omude, iNissan iklame futhi yethula inqwaba yemikhiqizo yezimoto emigqeni yayo yokuhlanganisa. Imishini yokukhathazeka kanye nezingxenye zayo zithole ukuqashelwa okukhulu kakhulu emhlabeni wonke. Namuhla sizokhuluma ngalokhu kokugcina. Ukunemba kakhudlwana, sizokhuluma ngamayunithi angama-2-litre ochungechunge lwe-NA amelwe yi-NA20P kanye ne-NA20S. Incazelo yawo wonke umehluko phakathi kwalezi zinjini, izici zabo zobuchwepheshe nezici zokusebenza zingatholakala ngezansi.
Umqondo nomlando wokudalwa kwezinjini
Ekuqaleni kwawo-80s ekhulwini elidlule, onjiniyela bakwaNissan babhekana nomsebenzi onzima nowemfanelo. Ingqikithi yayo bekuwukufaka esikhundleni sezinjini ezivuthayo zangaphakathi nezingasasebenzi zochungechunge lwe-Z ngento eqanjwe kabusha futhi engengaphansi kwekhwalithi.
Isixazululo sale nkinga sawela engxenyeni yesibili yama-80s, lapho ngo-1989 izinjini zomugqa we-NA ezibhekwa namuhla zangena ekukhiqizeni kwe-serial. Okulandelayo, ake sikhulume ngabameleli be-2-litre bochungechunge. Injini engu-1,6 litre izobhekwa ngesinye isikhathi.
Ngakho-ke, i-NA20s yenjini iyizimboni zamandla amalitha amabili akhiqizwa yi-Nissan. Ungahlangana nabo ngezinhlobonhlobo ezimbili ezihlukene:
- I-NA20S - injini ye-carburetor kaphethiloli.
- I-NA20P iyunithi yegesi enikwa amandla wuhlelo lomjovo olukhethekile.
Ngaphandle kohlobo lokushajwa kabusha, ukuhluka kwe-NA20s akuhlukile komunye nomunye. Zonke izinjini zochungechunge zenziwe ngesisekelo se-aluminium block kanye nekhanda layo, kanye nokusebenzisa i-camshaft eyodwa. Ngenxa yalo mklamo, kukhona ama-valve angu-4 kuphela kumasilinda angu-2 enjini. Ukupholisa kubo bonke abameleli bochungechunge kuwuketshezi.
Injini ye-NA20S yakhiqizwa kusukela ngo-1989 kuya ku-1999. Le yunithi ifakwe kuma-sedan e-Nissan concern. Yayisetshenziswa kakhulu kumamodeli weCedric kanye neCrew.
I-NA20P ikhiqizwe kusukela ngawo lowo nyaka futhi isenjalo. Umqondo wale njini ube yimpumelelo kangangokuthi usahlome ngesabelomali samamodeli amaJapan amakhulu. Ngokuvamile, igesi NA20 ingatholakala ku-Nissan Truck, Atlas and Caravan.

Amamotho e-NA20 akhiqizwa ngokukhethekile ezinhlobonhlobo zomoya ezinezici ezikhonjiswe etafuleni. Akunakwenzeka ukuthola amanye amasampula e-NA20S kanye ne-NA20P esesimweni sesitoko.
Ukusebenza nokulungiswa
I-Motor "NA" ayiphumelelanga kuphela ku-Nissan mayelana nemali engenayo evela ekuthengisweni kwayo, kodwa futhi nekhwalithi ephezulu kakhulu. Izinjini ezimbili-litre zomugqa azihlukile, ngakho-ke zinempendulo enhle kuphela evela kubo bonke abaxhaphazi babo.
I-NA20S noma i-NA20P ayinawo amaphutha ajwayelekile. Ngokulungiswa okuhlelekile nokufanelekile, amayunithi okukhulunywa ngawo awavamile ukuwohloka futhi ngaphezu kokuhlehlisa izinsiza zawo ezingamakhilomitha angu-300 - 000.
Uma ukuwohloka kwe-NA20 kungenakugwenywa, ungafaka isicelo sokuyikhanda kunoma yisiphi isiteshi sesevisi. Ukulungiswa kwalezi zinjini, njengazo zonke ezinye ezivela kwaNissan, kwenziwa izitolo eziningi zokulungisa izimoto, futhi izinkinga nazo zenzeka njalo.
Umklamo nomqondo ojwayelekile we-NA20S kanye ne-NA20P ulula ngokusesilinganisweni, ngakho-ke "ukubenza baphile" akunzima. Ngekhono elifanele kanye nolwazi oluthile, ungakwazi nokuzilungisa ngokwakho.
Mayelana nokwenziwa kwesimanjemanje kwe-NA20s, kuyenzeka impela. Nokho, akufanelekile ukulungisa lezi zinjini okungenani ngezizathu ezimbili:
- Okokuqala, akusizi ngokwemali. Kuzokwazi ukuphuma kuwo amandla angaphezu kuka-120-130, kodwa izindleko zizoba zibalulekile.
- Okwesibili, insiza izokwehla kakhulu - kuze kufike kumaphesenti angama-50 atholakalayo, okwenza futhi isimanje kube isenzakalo esingasho lutho.
Abashayeli bezimoto abaningi bayakuqonda ukungabi nanjongo kokuthuthukisa i-NA20S ne-NA20P, ngakho-ke isihloko sokuwashuna asithandwa phakathi kwabo. Kaningi, abanikazi balezi motors banesithakazelo ukuthi kungenzeka yini ukushintshwa.
Njengoba umkhuba ubonisa, inketho engcono kakhulu yokuqaliswa kokugcina kungaba ukuthenga injini yedizili yakwaNissan enegama elithi "TD27" noma inguqulo ye-turbo "TD27t". Kuwo wonke amamodeli womkhiqizi, alingana kahle, yiqiniso - ngokufaka esikhundleni se-NA20s.
