Izinjini FB25, FB25V Subaru
Okuqukethwe
I-brand yezimoto i-Subaru evela enkampanini yaseJapane enegama elifanayo yenza ukukhiqizwa kwezimoto zabagibeli, izimoto zezohwebo, izingxenye zomuntu ngamunye kanye nemihlangano yazo, kuhlanganise nezinjini.
Abaklami bahlale bewathuthukisa.
Ngo-2010, umhlaba wathola injini entsha yesibhakela ye-FB25V, kamuva eyashintshwa yaba yi-FB25.
Izici
Kuze kube ngu-2010, i-Subaru ihlomise izimoto zayo ngezinjini ze-EJ eziwu-2 no-2.5 amalitha. Ashintshwe amamotho ohlobo lwe-FB. Amayunithi awo womabili uchungechunge empeleni awahlukani kumingcele yezobuchwepheshe. Abaqambi benze umsebenzi okuhloswe ngawo ukwenza ngcono:
- wona kanye umklamo wesikhungo sikagesi;
- inqubo yokushiswa kwengxube yamafutha;
- izinkomba zezomnotho.
Amamotho ochungechunge lwe-FB athobela izinkambiso nezimfuneko zenani lokukhishwa kwezinto eziyingozi ngokuya nge-Euro-5.
Ezinye izici zesikhungo samandla salolu chungechunge zifaka:
- ukuba khona komshini wokulawula isikhathi se-valve, okuvumela ukwandisa amandla alinganisiwe;
- idrayivu yesikhathi yenziwa ngendlela yeketanga elinamagiya;
- igumbi lomlilo elihlangene;
- ukwanda kokusebenza kwepompo yamafutha;
- isistimu yokupholisa ehlukene ifakiwe.
Design ama-nuances
Ngenxa yezici zokuklama zenjini yesibhakela yochungechunge lwe-FB, onjiniyela bakwazile ukuguqula isikhungo samandla adonsela phansi emotweni kude kakhulu ngangokunokwenzeka. Ngenxa yalokhu, imoto ikwazi ukulawuleka.
Abathuthukisi bahlomise isikhungo samandla sochungechunge lwe-FB ngamasilinda anobubanzi obunyukile. Ama-cast iron liners afakwe ku-cylinder block, eyenziwe nge-aluminium. Ubukhulu bodonga lwazo buyi-3.5mm. Ukuze kuncishiswe ukungqubuzana, injini yayifakwe amapiston aneziketi eziguquliwe.
Isikhungo samandla se-FB 25 sinamakhanda amasilinda amabili, ngalinye linama-camshaft amabili. Ama-injector manje abekwe ngqo ekhanda le-cylinder.
Ngo-2014, uchungechunge lwe-FB25 ICE lwashintshwa. Izinguquko zithinte okulandelayo:
- ubukhulu bezindonga zesilinda buncishiswe ngo-0.3 mm;
- pistons esikhundleni;
- amachweba okungena akhuphuke afinyelela ku-36 mm;
- iyunithi yokulawula isistimu yomjovo entsha ifakiwe.

Inombolo kamazisi yenjini
Inombolo ye-serial yenjini iyinkomba yenjini evuthayo yangaphakathi. Namuhla alikho izinga elilodwa elinganquma indawo yenombolo enjalo.
Kumamodeli e-Subaru, kuvamile ukusebenzisa isihlonzi endaweni yesikhulumi, esenziwa ngomshini ekhoneni elingaphezulu kwesokunxele lodonga olungemuva lwesikhungo samandla. Okusho ukuthi, inombolo yenjini kufanele ibhekwe lapho kuhlangana khona iyunithi ngokwayo nedome yokudlulisela.
Ngaphezu kwalokho, unganquma uhlobo lwenjini evuthayo yangaphakathi ngekhodi ye-VIN. Ifakwa kuma-nameplates afakwe ngaphansi kwe-windshield ohlangothini lomshayeli nangemuva kwe-bulkhead ye-injini ohlangothini lwabagibeli. Uhlobo lwesikhungo sikagesi luhambisana nendawo yesithupha enombolweni enkulu yokuhlonza yemoto.
Izimoto ezinezinjini ze-FB25В kanye ne-FB25
Selokhu kwavela izinjini ze-FB25В ne-FB25, sezifakwe kumamodeli amaningi we-Subaru.
Isikhungo samandla se-FB25В sithole ukusetshenziswa kwaso ku-Subaru Forester, okuhlanganisa ukulungiswa kabusha kwesizukulwane sesi-4.
Lezi zinhlobo zezimoto ezilandelayo zifakwe injini ye-FB25:
- Subaru Exiga;
- I-Subaru Exiga Crossover 7;
- I-Subaru Forester, kusukela esizukulwaneni sesi-5;
- Ifa le-Subaru;
- Ifa le-Subaru B4;
- ISubaru Outback.
Ukungalungi kwezinjini ze-FB25В kanye ne-FB25
Kanye nezinzuzo eziningi zezinjini ze-FB25, kunezinombolo zokubi. Phakathi kwazo kukhona okulandelayo:
- ukusetshenziswa kwamafutha amaningi;
- ukupheka izindandatho ze-oil scraper;
- uhlelo lokupholisa olungaphelele, oluholela ekushiseni ngokweqile kwenjini kanye nendlala kawoyela;
- Ukushintsha ama-spark plug kuwumsebenzi omningi.
Ngokuvamile, kunconywa ukusebenzisa izimoto ezinenjini ye-FB25 ngendlela emnene. Uma kungenjalo, insiza iyancipha kakhulu.
Uma kwenzeka ukwehluleka kwesikhungo sikagesi, kuzodingeka kwenziwe ukulungiswa kabusha okukhulu. Kulokhu, kunconywa ukuthi uxhumane nesiteshi sesevisi esikhethekile. Lokhu kuzoba ukhiye wokubuyiselwa kwenjini yekhwalithi ephezulu nephrofeshinali. Lapho ushintsha izingxenye, sebenzisa izingxenye zangempela kuphela.
Injini yenkontileka
I-FB25 motor iyalungiseka. Kodwa-ke, izindleko zezingxenye zokulungiswa kabusha kwezinjini ezivuthayo zangaphakathi ziphezulu kakhulu. Ngakho-ke, kuhle ukucabanga ngokuthenga injini yenkontileka.
Intengo yayo incike esimweni sobuchwepheshe. Namuhla ingasuka ku-2000 US dollar.
Amafutha enjini ka-FB 25
Umkhiqizi ngamunye uncoma ukusebenzisa uhlobo olufanele lwamafutha enjini ohlotsheni oluthile lwenjini. Ezitshalweni zamandla FB 25, umenzi weluleka ukusetshenziswa kwamafutha:
- 0W-20 I-Subaru Yangempela;
- 0W-20 Idemitsu.
Ukwengeza, amafutha afanele injini, ebonakala ngezinkomba ezilandelayo ze-viscosity:
- 5W-20;
- 5W-30;
- 5W-40.
Umthamo wamafutha enjini ungama-4,8 amalitha. Ngokusho kwebhukwana, kunconywa ukushintsha uwoyela njalo ngamakhilomitha ayi-15000. Abashayeli bezimoto abanolwazi bayeluleka ukwenza lokhu ebangeni elilinganiselwa ku-7500 km.
Ukushuna noma ukushintshanisa
Izinjini ze-FB25 kanye ne-FB25B zathuthukiswa njengesikhungo samandla somoya. Ngakho-ke, akufanele uzame ukufaka i-turbine kuyo. Lokhu kuzoholela ekulahlekelweni ukwethembeka nokwehluleka kweyunithi.
Njengokushuna
- susa i-catalyst ohlelweni lwe-exhaust;
- kwandisa i-exhaust eningi;
- shintsha izilungiselelo zeyunithi yokulawula injini (i-chip tuning).
Lokhu kuzongeza amandla angu-10-15 enjini yakho.
Ngenxa yezici zokuklama ze-FB25 ICE, akunakwenzeka ukwenza ukushintshaniswa.
Ukubuyekezwa Komnikazi Wezimoto
Kukhona ukubuyekezwa okuhlukile phakathi kwabanikazi bezimoto ze-Subaru Forester kanye ne-Legasy. Abaningi badidekile ngokusetshenziswa kakhulu kukawoyela. Ngokuvamile, abashayeli bathanda le moto ngenxa yokuthembeka kwenjini, ukuphatha, ikhono lokuwela izwe, i-Subaru's proprietary all-wheel drive.
