Izimoto ezinezinjini ze-SR18DE

Izinjini ze-SR zibandakanya izinjini ezine-cylinder ezine-stroke ezine-displacement engu-1.6, 1.8 no-2 litre. Zazisekelwe ku-aluminium cylinder block kanye nekhanda le-cylinder, futhi ama-manifolds ayenziwe ngensimbi. Lawa mayunithi kagesi ahlome izimoto ezisezingeni eliphakathi nezincane zakwaNissan. Ngaphezu kwalokho, amanye ama-motor ayefakwe i-turbine. Uchungechunge lwenjini ye-SR luthathe indawo yolayini we-CA.

Japanese SR18DE amandla iyunithi "Nissan" - 1,8-litre injini, ukukhiqizwa eyaqala emuva ngo-1989 futhi yaqhubeka kwaze kwaba ngu-2001. Uzisungule njengemoto ehlala isikhathi eside ngaphandle kwamaphutha abalulekile nezifo.

Umlando wenjini ye-Nissan SR18DE

Isizinda samandla se-SR18DE esivela kwaNissan sakhiqizwa ngesikhathi esifanayo nazo zonke izinjini ezithandwayo ezingama-20 litre SR1,6 kanye nenjini yezemidlalo engu-16-litre SR18VE. I-SR1,8DE ibekwe njengenjini ethule futhi eyongayo eshintshwayo engu-XNUMX litres.

Isisekelo sephrojekthi yakhe kwakuyinjini ye-SR20 enamalitha amabili enezinguquko ezithile ngendlela yama-pistons amancane nama-valve okuphuza nawokukhipha. Abathuthukisi baphinde bashintsha ama-camshafts, ngaleyo ndlela bashintsha isigaba kanye nemingcele yokuphakamisa. Ngaphezu kwalokho, iyunithi yokulawula entsha ibhekene nakho konke ukusebenza kwenjini, kodwa ngaphandle kwalokho kuseyi-SR20DE efanayo, i-1,8-litre kuphela.

Ukuze uthole ireferensi! Ngaphezu kwenjini ye-SR18DE, eyayihlukaniswa nesistimu yomjovo we-fuel distributive, enye injini engu-1,8-litre SR18Di yakhiqizwa, kodwa ngomjovo owodwa futhi, ngokufanele, i-cylinder head ehlukile (HC)!

Njengenguqulo yayo yangaphambilini enamalitha amabili, i-SR18DE ifakwe ama-hydraulic lifters, okuvumela ukuthi ukhohlwe ukulungisa ama-valve. I-camshaft yomshini wokusabalalisa igesi ine-chain drive (Timing Chain), yona ngokwayo iyisistimu enokwethenjelwa kakhulu engahlala ngaphezu kwe-200 km. Isithombe esingezansi sibonisa i-ignition distributor (isabalalisi) SR18DE: Injini ye-Nissan SR18DE

Unyaka wokugcina ukukhiqizwa kwale njini ngu-2001. Ngawo lowo nyaka, kwethulwa isamukeli se-SR18DE - iyunithi yamandla entsha nesezingeni eliphezulu ye-QG18DE.

Ukuze uthole ireferensi! Iyunithi yamandla ye-SR18DE ifakwe i-MPI (Multi-Point Injection) isistimu yomjovo kaphethiloli wamaphoyinti amaningi, okuyinto evamile kumamodeli enjini yokuqala. Kodwa-ke, kakade ezinguqulweni zakamuva zenjini, i-GDI entsha (i-Gasoline Direct Injection) ifakwe isistimu yomjovo kaphethiloli oqondile, onganikezi uphethiloli endaweni eningi yokuthatha, kodwa ngqo ekamelweni elivuthayo!

Ukucaciswa kwenjini SR18DE

Wonke amapharamitha wezobuchwepheshe abaluleke kakhulu ale yunithi yamandla avezwa etafuleni elingezansi:

Izici zokusebenza kwenjini ye-SR18DE

Izinjini zomugqa we-SR, kufaka phakathi i-SR18DE, zihlukaniswa ngokuthembeka nokuqina kwazo. Naphezu kweqiniso lokuthi abanakho ukushiyeka emhlabeni jikelele, ngezinye izikhathi kuba nokungenzi lutho okuntantayo, okubonisa isilawuli sejubane esihlulekile.

I-XX ingalungiswa ngokufaka isilawuli esikhundleni. Isivinini senjini entantayo singabonisa nokusetshenziswa kukaphethiloli wekhwalithi ephansi. Ngaphezu kwalokho, ukwahlulela ukubuyekezwa abanikazi balo injini, ukungasebenzi kahle kwenzwa yokugeleza komoya (DMRV) ngezikhathi ezithile.

Ngokuvamile, insiza ye-gas distribution mechanism (GRM) ingamakhilomitha angaba ngu-300 XNUMX, emva kwalokho uchungechunge lwezikhathi lungahle luhlehle. Lesi yisibonakaliso sokuqala sokuthi yeluliwe futhi idinga ukushintshwa.

Okubalulekile! Kubaluleke kakhulu ukuqapha njalo izinga likawoyela wenjini enjinini. Ngempela, ngesikhathi sokulamba kukawoyela, lonke iqembu le-piston libhekene nokuguga okukhulayo, okuhlanganisa amajenali wenduku eyinhloko kanye nokuxhuma kanye nama-crankshaft liners!

Isithombe esingezansi sibonisa izici zendlela yokusabalalisa igesi: Injini ye-Nissan SR18DE

Ngisho neqiniso lokuthi i-SR18DE inezinga eliphezulu lokuthembeka aliwaphikisi amanye amaphutha atholakala kuzo zonke izinjini. Isibonelo, injini engeke iqale noma iqale kabi lapho kubanda ingabonisa ipulaki yenhlansi enephutha noma iphampu yesibaseli engakhiqizi ukucindezela okulungile. Kubaluleke kakhulu ukuqapha umbuso wokushisa wenjini, ongaphazanyiswa ngenxa yokungasebenzi kahle kwe-thermostat, engavuli umbuthano omkhulu wokujikeleza okupholile.

Ukuze uthole ireferensi! Ngaphezu kwezinkinga zenjini ye-SR18DE, kukhona nezinkinga nge-othomathikhi - imvamisa amagiya avele anyamalale, okuholela ekulungisweni noma esikhundleni sayo yonke i-gearbox. Okubalulekile kula mayunithi amabili ukuthi ayabambana, okungukuthi, injini kanye ne-automatic transmission ilungiswa ngemicamelo ekhethekile, eyodwa ebamba injini no-gearbox wesibili. Ukuze ususe i-gearbox ezenzakalelayo, kuyadingeka ukufaka i-fulcrum eyengeziwe ngaphansi kwe-motor!

Ukushisa ngokweqile kwenjini kungaphazamisa ubuqotho be-pistons nama-cylinder liners, kanye nokushayela i-GCB, okuzoholela ekunciphiseni kokucindezela injini noma ngisho nokushintshwa kwekhanda le-cylinder. Ngokuqondene nesistimu yokupholisa, kunconywa ukuthi kushintshwe iphampu (ipompo yamanzi) kanye nokushintshwa kwedrayivu yesikhathi. Abanye abanikazi bezimoto ezinezinjini ze-SR18DE bakhononda ngokwanda kokudlidliza kwenjini. Lapha, ukukhwezwa kwenjini, osekugugile futhi kwaphelelwa amandla, kungase kube necala.

Ukuze uthole ireferensi! Izinga lokushisa lokuvula i-thermostat liyahlukahluka kusuka ku-88 kuya ku-92 degrees. Ngakho-ke, uma injini ingene kumodi yayo yokusebenza, futhi i-coolant isajikeleza embuthanweni omncane (ngaphandle kokungena kurediyetha), lokhu kubonisa i-thermostat eminyene!

Ngezansi kunomdwebo wendawo yezinto eziyinhloko zenjini: i-thermostat, i-starter, izindawo zokufaka i-ICE relay, njalonjalo. Injini ye-Nissan SR18DE

Iyunithi yamandla ye-SR18DE ingashunwa, nakuba lokhu kuzokwandisa amandla ayo kancane. Kulula kakhulu ukushintshanisa ku-SR20DET/SR20VE futhi kakade kuyinguqulo eyisisekelo, ukuphuma kwamandla kuzoba ngu-200 hp. I-SR20DET ngemuva kokuthi i-boost ikhiqize i-300 hp.
