Injini ye-turbo engu-1.8 - incazelo yeyunithi yamandla engu-1.8t yezimoto zeVolkswagen, Audi ne-Skoda

Le njini ibisetshenziswa kakhulu ezinhlotsheni eziningi zeVolkswagen, Audi, Seat neSkoda. Ukukhiqizwa kwezimoto ezinenjini engu-1.8 turbo kwaqala ngo-1993, futhi iqembu lamamodeli weminyaka yokuqala yokukhiqiza le yunithi yamandla kuhlanganisa, phakathi kokunye, iVW Polo Gti, New Beetle S noma i-Audi A3 ne-A4. I-Seat iphinde yakhiqiza izinhlobo ze-Leon Mk1, Cupra R kanye ne-Toledo, kanti i-Skoda ikhiqize uhlobo olulinganiselwe lwe-Octavia Rs enenjini engu-1.8 turbo. Yini enye okufanele ukwazi?

Injini ye-turbo engu-1.8 - imininingwane

Idivayisi yethulwa ngo-1993. Kwakuhlukile kwe-EA113 eyathatha indawo ye-EA827 efakwe ku-Audi 80 futhi yaklanywa ngu-Ludwig Kraus emuva ngo-1972. Inguqulo entsha ifakwe umjovo oqondile we-FSI (I-Fuel Stratified Injection). Inguqulo engcono kakhulu yileyo esetshenziswe ku-Audi TTS enama-268 hp. Kwabe sekwethulwa inguqulo ye-EA888, eyasetshenziswa ngezinjini ze-1.8 TSI / TFSI - EA113, noma kunjalo, yahlala ekukhiqizeni. 

Incazelo yobuchwepheshe yeyunithi yamandla

Lesi sithuthuthu sisebenzisa i-cast iron cylinder block kanye nekhanda le-aluminium cylinder elinamakhamera angaphezulu aphindwe kabili kanye nama-valve amahlanu isilinda ngasinye. Ukususwa kwangempela kweyunithi kufakwe kuhlu njengo-1781 cm3 ngenxa yobubanzi bebhore kanye ne-stroke, ngokulandelana 81 mm no-86 mm. Kuyaphawuleka ukuthi injini ibuye ibaluleke kakhulu ngenxa yamandla ayo aphezulu, okuwumphumela wokusetshenziswa kwe-crankshaft yensimbi eyakhiwe, izinduku zokuxhuma ezakhiwe ngokuhlukaniswa kanye nama-pistons angama-Mahle (kwezinye izinhlobo).

Yini eyenza le njini ihluke?

Isici sesici esihlukanisa le yunithi yikhanda eliphefumula kahle kakhulu, kanye ne-turbocharger eklanywe kahle kanye nesistimu yomjovo. Icompressor esebenza kahle enezakhiwo ezicishe ilingane ne-Garrett T30 inesibopho sokusebenza kahle kwenjini.

Ukusebenza kwe-turbine enjinini engu-1.8t

Kuyafaneleka ukuchaza ngokuningiliziwe ukusebenza kwe-turbine engu-1.8 t. Iphakela ubude obuhlukahlukene obuhlukahlukene. Uma ama-revs ephansi, umoya udlula isethi yamapayipi amancane namade amade. Lokhu kunikeza okuhle torque, kanye nokuphatha okungcono kakhulu kuma-revs aphansi. Lapho kukhiqizwa ama-RPM aphezulu, i-flap iyavuleka, ixhuma indawo enkulu nevulekile ye-multifold intake cishe ngqo ekhanda le-cylinder, idlula amapayipi futhi ikhulise amandla amakhulu. 

Hlanganisa i-1.8 t kumklamo wezemidlalo

Ngaphezu kwezinketho ezijwayelekile zeyunithi, bekukhona nezici zezemidlalo. Bebekhona ezimotweni ezibambe iqhaza ochungechungeni lwemijaho yeFormula Palmer Audi ehlelwa kusukela ngo-1998 kuya ku-2010. Kwasetshenziswa inguqulo ye-turbo ye-Garrett T300 ene-34 hp. eshajwe kakhulu. Lesi sici semishini sivumele umshayeli ukuthi akhuphule amandla kafushane abe ngu-360 hp. Kuyathakazelisa ukuthi iyunithi yakhiqizelwa izimoto zochungechunge lwe-FIA ​​Formula 2. Amandla iyunithi enjalo ekwazi ukuyiletha yayingama-425 hp. nethuba lokushaja kakhulu kuze kufike ku-55 hp 

Injini engu-1.8 t ezimotweni zabagibeli i-Audi, VW, Seat, njll.

Kuyaphawuleka ukuthi esimweni samathani angu-1.8 kunzima ukukhuluma ngenketho eyodwa kuphela. IVolkswagen ikhiphe izinguqulo ezingaphezu kweshumi nambili eminyakeni edlule. Zazihlukene ngamandla, izinto zokusebenza nendlela yokuhlanganisa - i-longitudinal noma i-transverse. Eyokuqala itholakala ezinhlotsheni ezifana neSkoda Superb, i-Audi A4 ne-A6, neVW Passat B5. Ngohlelo oluphambene, le yunithi isetshenziswe ku-VW Golf, Polo Skoda Octavia, Seat Toledo, Leon nase-Ibiza. Kuye ngenguqulo, bangaba namandla angu-150, 163, 180 no-195 hp. Izinketho ze-FWD ​​ne-AWD nazo ziyatholakala.

Injini engu-1.8t ivamise ukusetshenziselwa ukulungisa izimoto.

Amayunithi asuka eqenjini le-1.8t avame ukushunwa, futhi izinkampani eziningi, njenge-MR Motors noma i-Digitun, zingaziqhenya ngolwazi olubanzi ekulungisweni kukagesi nemishini ezimotweni ezinale njini. Enye yezinguquko ezivame kakhulu ukushintshwa kwenjini. Isici esibalulekile ukuthi idivayisi ikhwezwa kanjani. Okulula futhi okungabizi kakhulu wukushintsha injini enamandla kakhulu ephambanayo ufake ebuthakathaka nayo ebifakwe ngokuphambana. Indlela yokuhlanganisa ibalulekile nasemongweni wokushintsha i-gearbox. I-1.8 t unit ingaphinde ifakwe ezimotweni le njini ebingafakwanga kuzo ekuqaleni. Lawa amamodeli afana neGolf I noma II, kanye neLupo neSkoda Fabia. 

Abanikazi bezimoto ezinenjini engu-1.8 t baphinde banquma ukushintsha i-K03 turbocharger bafake i-K04 noma imodeli ebiza kakhulu. Lokhu kwandisa kakhulu amandla atholakalayo kumshayeli. Ukuguqulwa kwe-turbo enkulu kuhlanganisa nokushintshwa kwama-injector, imigqa ye-IC, i-clutch, iphampu yamafutha nezinye izingxenye. Lokhu kwenza ukuguqulwa kusebenze kakhulu futhi injini ikhiqiza amandla amaningi.
