Injini ye-Nissan SR20De

Injini ye-Nissan SR20De imele umndeni omkhulu wamayunithi wamandla kaphethiloli wenkampani yaseJapan, ehlanganiswe nenkomba ye-SR. Umthamo walezi zinjini wawusukela ku-1,6 kuya ku-2 amalitha.

Isici esiyinhloko sezobuchwepheshe salezi zinjini yikhanda le-aluminium cylinder kanye nensimbi, empeleni, i-cylinder block. Lezi zinjini ezivuthayo zangaphakathi (ICE) zakhiqizwa kusukela ngo-1989 kuya ku-2007.

Izinombolo ekumaka kweyunithi yamandla zibonisa usayizi wenjini. Okungukuthi, uma uhlobo injini SR18Di, ivolumu yayo - 1,8 amalitha. Ngakho-ke, ngenjini ye-SR20De, ukususwa kwenjini kulingana namalitha amabili.

Izinjini zochungechunge lwe-SR kanye, ikakhulukazi, izinjini zamalitha amabili zalolu chungechunge, zifakwe ohlwini olukhulu kakhulu lwezimoto zabagibeli ezikhiqizwa yi-Nissan eminyakeni engu-90 "zero".

Umlando wenjini ye-Nissan SR20De

Phakathi kwawo wonke amayunithi wamandla ochungechungeni lwe-SR, i-SR20De idume kakhulu, futhi umuntu angase athi edumile ezweni lakithi. Lawa ma-motor afakwe kwimodeli yesizukulwane sesishiyagalombili ye-Nissan Bluebird, eyangeniswa ngenkuthalo, okokuqala e-USSR, bese eya eRussia, ngabathengisi abampunga noma ama-distillers.

Ngaphambi kokufika kwalezi zinjini, emkhakheni we-2-litre power units, amaJapane akhiqiza i-CA20. Le njini yayinzima impela, ngokwesisindo, ngoba ibhulokhi nekhanda layo kwakunensimbi ewukhonkolo. Ngo-1989, ukukhanya, i-aluminium SR20s yafakwa kuma-Bluebirds, okwaba nomthelela omuhle kuzo zombili izici eziguqukayo zezimoto nokusebenza kahle kwazo. Futhi, ngenxa yomnotho nokusebenza okuphezulu, lezi zinjini ezivuthayo zangaphakathi zine-injector enamaphuzu amaningi nama-valve amane isilinda.

Kusukela ekuqaleni kokukhiqiza, ikhava ye-valve ebomvu yafakwa kulawa mayunithi amandla. Ngenxa yalokhu, izinjini zithole igama elithi SR20DE Red top High port. Lawa ma-ICE ema kulayini wokuhlanganisa kwaze kwaba ngu-1994, lapho athathelwa indawo izinjini ze-SR20DE Black top Low port.

Kusukela kumanduleli walo, ngaphezu kwesembozo se-valve emnyama, le yunithi yamandla yahlukaniswa iziteshi ezintsha zokungena zekhanda le-cylinder (ikhanda le-cylinder). I-camshaft entsha engu-240/240 (eyandulelayo yayine-camshaft engu-248/240) kanye nesistimu yokukhipha umoya entsha enamapayipi angu-38mm (imbobo ye-SR20DE Red top High yayinamapayipi angu-45mm). Le injini yema emgqeni womhlangano kuze kube ngu-2000, nakuba ingekho esimweni esingashintshiwe, ngo-1995, injini entsha yavela ku-238/240 camshaft.

Ngo-2000, imbobo ye-SR20DE Black top Low yathathelwa indawo yi-rocker ICE ethuthukisiwe ye-SR20DE. Izici eziyinhloko zale yunithi yamandla bekungama-roller rocker kanye neziphethu zokubuya kwamavalvu amasha. Ezinye izinguquko okufanele ziqashelwe ama-pistons ashintshwe kancane, i-crankshaft elula kanye nenani elifushanisiwe lokuthatha. Lokhu kuguqulwa bekusenziwa kuze kube ngu-2002. Ngemuva kwalokho, izinjini zasemkhathini ze-SR20DE zanqanyulwa. Nokho, izinguqulo ze-turbocharged zale njini ziqhubekile nokukhiqizwa futhi umlando wazo uzoxoxwa ngakho ngezansi.

Umlando wezinjini ze-SR20DET ezine-turbocharged

Cishe kanyekanye nenjini eshisekelayo ngokwemvelo, kwavela inguqulo yayo ene-turbocharged, enegama elithi SR20DET. Inguqulo yokuqala, ngokufanisa nenjini efisa ngokwemvelo, yayibizwa ngokuthi i-SR20DET Red top. Le ICE yakhiqizwa, njengenguqulo yayo yomoya, kwaze kwaba ngu-1994.

Le moto yayine-Garrett T25G turbine, ekhiqize ingcindezi ye-0,5 bar. Lokhu kuphoqa kwenze kwaba nokwenzeka ukuthuthukisa amandla angu-205 hp. ngo-6000 rpm. I-torque yenjini evuthayo yangaphakathi ingu-274 Nm ku-4000 rpm.

Ukuze usindise impilo yenjini, isilinganiso sokucindezela sancipha saba ngu-8,5 futhi izinduku zokuxhuma zaqiniswa.

Ngokuhambisana nale yunithi yamandla, ngo-1990 kwavela inguqulo yayo enamandla nakakhulu, enamandla angu-230 hp. ku-6400 rpm kanye ne-torque engu-280 Nm ku-4800 rpm. Ihluke kokwandulelayo nge-turbine ehlukile ye-Garrett T28, ekhiqize ingcindezi ye-0,72 bar. Futhi, ngaphezu kwalokhu, izinguquko ezilandelayo zenziwa kuyunithi yamandla. Uthole i-camshaft ehlukile engu-248/248, amanye ama-injection kaphethiloli anamandla angama-440 cm³ / min, amanye ama-nozzles kawoyela, i-crankshaft, izinduku zokuxhuma namabhawodi ekhanda lesilinda aqiniswa.

Njengenguqulo ye-atmospheric, isizukulwane esilandelayo saleyunithi yamandla savela ngo-1994. Uthole igama elithi Nissan SR20DET Black top. Ngaphezu kwekhava yevalvu emnyama, eyaba wuphawu lwale njini, iphinde yaba ne-lambda probe entsha namapiston. Ngaphezu kwalokho, iziteshi zokungena neziphumayo zashintshwa, kanye nesethingi yekhompyutha esebhodini yashintshwa.

Inguqulo ehluke kancane, enamandla kakhulu yale njini yakhululwa imoto yezemidlalo ye-Nissan S14 Silvia. Le moto yayinenjini engu-220 hp. ku-6000 rpm kanye ne-torque engu-275 Nm ku-4800 rpm.

Kodwa-ke, inguqulo ethuthuke kakhulu yeyunithi yamandla yafakwa esizukulwaneni esilandelayo, isizukulwane sesikhombisa uSylvia, esasiphethe inkomba ye-S15. Injini kule moto yayine-turbo ye-Garrett T28BB ene-intercooler eyenza ingcindezi engu-0,8 bar. Ngaphezu kwalokho, yayifakwe i-mono nozzle enamandla angu-480 cm³ / min. Ngemva kwalesi simanjemanje, injini evuthayo yangaphakathi yakha amandla angu-250 hp. ku-6400 rpm futhi ibe ne-torque engu-300 Nm ku-4800 rpm.

Ezinye izinguqulo ezimbili ze-SR20DET bezikwinqola yesiteshi i-Nissan Avenir eyaziwa kancane. Kulo mshini, amandla amabili, amayunithi amabili-litre anamandla angu-205 no-230 hp athuthukiswa kanyekanye. Lawa ma-motor aqanjwa ngokuthi i-Nissan SR20DET Silver top. Imininingwane eyinhloko ehlukanisayo yalezi ziyunithi kwakuyisembozo se-valve empunga.

Nokho, inguqulo enamandla kunazo zonke injini "Nissan SR20" ifakiwe, kakade ekhulwini lama-21, eyaziwa kakhulu "Nissan X-Trail GT" crossover. Yiqiniso, le nguqulo ye-crossover ayizange ithengiswe ngokusemthethweni eRussia.

Ngakho-ke, le nguqulo yayibizwa nge-SR20VET futhi yafakwa esizukulwaneni sokuqala se-X-Trails emakethe yaseJapane. Le nguqulo, njengesizukulwane sokuqala se-crossover, yakhiqizwa kusukela ngo-2001 kuya ku-2007. Le ICE ithuthukise amandla angu-280 hp. ku-6400 rpm futhi ibe ne-torque engu-315 Nm ku-3200 rpm. Ezicini zokuklama zale yunithi yamandla, kufanelekile ukuqaphela ama-camshafts angu-212/248 kanye ne-Garrett T28 turbine, ene-boost pressure ye-0,6 bar.

Ekuphetheni indaba yomlando wenjini ye-Nissan SR20De, kufanele kushiwo ukuthi isiye yaba yinto evamile kakhulu phakathi kwawo wonke uchungechunge lwe-SR.

Ukuthembeka kwezimoto

Ngokwehlukana, kufanele kushiwo mayelana nomthombo walesi motor, njengoba iningi lamayunithi amandla angaleso sikhathi, akhiqizwa ezweni eliphuma ilanga, cishe phakade. Iqembu labo le-piston, kalula, lihamba amakhilomitha ayingxenye yesigidi noma ngaphezulu. Ngamanye amazwi, lezi zinjini ezivuthayo zangaphakathi zinomthombo omude kakhulu kunomthombo wemizimba yezimoto ezifakwe kuzo.

Ezinkingeni ezingathí sina kakhulu kulawa mayunithi amandla, ukwehluleka ngaphambi kwesikhathi kwesilawuli sesivinini esingenzi lutho kanye nenzwa yokugeleza komoya omningi kuyaphawulwa. Lezi zinkinga zivela ikakhulukazi ngenxa yezinga eliphansi likaphethiloli ezweni lakithi.

Yebo, ngaphezu kokuthembeka okukhethekile kweqembu le-piston, inzuzo yalezi zithuthuthu ukungabikho kwebhande kumshini wokushayela isikhathi. Lawa ma-motor ane-camshaft chain drive, kanti iketango lona linomthombo ongamakhilomitha angama-250 - 300.

Hlobo luni lwamafutha lokuthela

Njengazo zonke izinjini ze-corporation, i-Nissan SR20 ayinaso kakhulu uwoyela osetshenzisiwe. Amafutha alandelayo e-API angasetshenziswa kule injini:

• I-5W-20
• I-5W-30
• I-5W-40
• I-5W-50
• I-10W-30
• I-10W-40
• I-10W-50
• I-10W-60
• I-15W-40
• I-15W-50
• I-20W-20

Ngokuqondene nomkhiqizi kawoyela, inkampani yaseJapane incoma ukusebenzisa amafutha ayo. Futhi kunengqondo kakhulu ukuzisebenzisa. Iqiniso liwukuthi amafutha e-Nissan awatholakali ukudayiswa mahhala, atholakala kuphela kubathengisi abasemthethweni benkampani futhi ukusetshenziswa kwabo kuqinisekisa ukuthi uzogcwalisa uwoyela wangempela ngempela, ukumaka okuhambisana nokuqukethwe kwawo ku-canister.

Nokho, mayelana nolwazi oluku-canister, ke:

• Strong Save X - igama lamafutha;
• 5W-30 - ngezigaba zayo ngokuvumelana API;
• SN - idijithi yokuqala kulokhu kumaka ikhombisa ukuthi la mafutha engezaziphi izinjini;

1. I-S - ibonisa ukuthi lokhu kungamafutha ezinjini zikaphethiloli;
2. C - ngodizili;
3. I-N - ibonisa isikhathi sokuthuthukiswa kwamafutha. Lapho uhlamvu luqhubeka lusuka kuhlamvu lokuqala "A", yilapho luba lwesimanje. Isibonelo, amafutha "N" avela kamuva kunamafutha anohlamvu "M".

Uhlu lwezimoto lapho le njini ifakwe khona

Injini ye-Nissan SR20De yayingenye yezingxenye zamandla ezivame kakhulu zenhlangano yaseJapane. Ifakwe ohlwini olude lwamamodeli:

• Nissan Almera;
