Injini yeVolkswagen CMBA
Okuqukethwe
Ikakhulukazi ukuhlomisa iVolkswagen Golf yochungechunge lwesikhombisa, kwasungulwa iyunithi yamandla entsha ngokuyisisekelo, eyafakwa kulayini we-EA211-TSI (CHPA, CXSA, CZCA, CZDA, CZEA, DJKA).
Incazelo
Injini ye-CMA yadalwa ngo-2012, kodwa ngemva konyaka yaqala ukushintshwa ngenye imodeli (CXSA). Inqanyulwe ngo-2014.
Ukuphila okufushane kwenjini yomlilo yangaphakathi kwaba lula ngenxa yezinkinga ezivele ngesikhathi sokusebenza kwemoto.
Ngesikhathi sokuthuthukiswa kweyunithi, onjiniyela bokukhathazeka kwe-VAG benza amaphutha, ngenxa yalokho i-CMA ayizange iphumelele. Ubuthakathaka kuzoxoxwa ngakho kabanzi ngezansi.
IVolkswagen CMBA ICE iwushintsho oluyisisekelo lokuqala lwenjini engu-1.4 TSI EA211. Ivolumu yenjini ingu-1,4 amalitha, amandla angu-122 amalitha. s ku-torque engu-200 Nm. I-Supercharging yenziwa i-TD025 M2 turbine (ingcindezi eyeqile engu-0,8 bar).
Le yunithi ifakwe ezimotweni zokukhathazeka kwe-VAG:
Isici seyunithi ukwakheka kwayo kwe-modular. Isixazululo esinjalo sobuchwepheshe kanye "ne-pluses" sine "minuses" eminingi.
I-cylinder block yenziwe nge-aluminium, ama-liners ayinsimbi ensimbi, enezindonga ezincane. Ama-piston alula, i-crankshaft nezinduku zokuxhuma. Ukunciphisa isisindo senjini yomlilo yangaphakathi kunomphumela omuhle ekusebenzeni. Ngesikhathi esifanayo, kwandisa kakhulu izindleko zokulungisa.
I-block head iyi-aluminium, inama-camshaft amabili (DOHC) nama-valve angu-16 afakwe izinxephezelo ze-hydraulic. Isilawuli sesikhathi se-valve sifakwe ku-shaft yokungenisa.
Isikhathi sokushayela ibhande. Inomsindo omncane kunamaketango, kodwa iyinkinga kakhulu. Kuyadingeka ukuhlola isimo ibhande njalo km 30 ayizinkulungwane, futhi esikhundleni salo ngemva 90 ayizinkulungwane km. Uma ibhande liphuka, ama-valve ayagoba.
I-turbine ayibangeli inkinga enkulu kumnikazi, kodwa ukushayela kwayo kwenza imfoloko ibe nenani elikhulu. Kwesinye isikhathi ungakwazi ukususa i-actuator, kodwa kwezinye izimo kufanele umiselele wonke ukuhlanganiswa kwe-turbine.
Injini isebenza ngokuvilapha kuphethiloli we-95, obuye ube nomthelela ezinkingeni eziningi ezibucayi futhi unciphise impilo yeyunithi.
Isistimu yokupholisa iyisiyingi kabili. Iphampu iyipulasitiki futhi ayiqinile. Ama-thermostats anconywa ukuthi ashintshwe ngemva kwamakhilomitha ayizinkulungwane ezingu-90. Iphampu ithatha ukunakekelwa okwengeziwe.
Injini ilawulwa yi-Bosch Motronic MED 17.5.21 ECU.

Ukuthembeka, ubuthakathaka, ukugcina
Ukuthembeka
Ngeshwa, i-CMBA ayiyona ingxenye yesigaba sabathembekile. Umkhiqizi unqume insiza mileage 250 ayizinkulungwane km, kodwa umkhuba ubonisa ukuthi injini ehluleka kakhulu ngaphambili. Abanikazi bezimoto abaningi kwadingeka balungise iyunithi ngemuva kwe-70 km.
Ngokusebenzisa kahle injini yomlilo yangaphakathi, ungafinyelela ukwanda kwemayela. Kodwa lokhu "okulungile" akwenzeki ngaso sonke isikhathi ukukusebenzisa. Isibonelo, ikhwalithi yamafutha ethu nezinto zokugcoba, ikakhulukazi uphethiloli, ibangela ukugxekwa okukhulu. Kunezimo eziningi lapho abanikazi bezimoto bezama ngokuzimela ukulungisa ezinye izinto ezingalungile ngezandla zabo, ngaphandle kokuba nolwazi olufanele emsebenzini wokulungisa, ("ngokusho kwencwadi").
Umkhiqizi ugcina izindaba zokuthembeka kwenjini ngaphansi kokulawulwa njalo. Ngakho-ke, ngo-September 2013, ukuklanywa kwekhanda le-cylinder kwashintshwa. I-maslozhor yehla ngokuphawulekayo, kodwa ayizange iphele ngokuphelele. Okunye ukuthuthukiswa kweyunithi nakho akuzange kunikeze umphumela olindelekile. Injini yahlala inenkinga.
I-CMBA inomkhawulo omuhle wokuphepha. Inganyuswa ifike ku-200 litres. s, kodwa ngesikhathi esifanayo babhebhethekise zonke "izilonda" ezikhona. Abalandeli bokushuna badinga ukwazi ukuthi ukushuna kwe-chip okulula (Isigaba 1) kwenyusa amandla ku-155 hp. s, inkimbinkimbi (Isigaba 2) isivele ifika ku-165. Kodwa futhi, khumbula ukuthi noma yikuphi ukungenelela ekwakhiweni kwemoto kuzonciphisa kakhulu insiza yayo evele incane.
Izindawo ezibuthakathaka
Ukwenyuka kokusetshenziswa kwamafutha (maslozhor). Lokhu kwenzeka ngenxa yokukhubazeka ekhanda le-cylinder, ama-valve stem seal namasongo e-piston.
Ukwehlukana kwedrayivu yokulawula i-turbine (i-jamming of the wastegate actuator rod). Ukucasula ukungasebenzi kahle ukukhethwa okungalungile kwezinto zokwakha izingxenye zokushayela kanye nokusebenza kwesikhathi eside kwenjini yomlilo yangaphakathi ngesigqi esifanayo (cishe ngesivinini senjini esingaguquki).
Ukuklama okungaphumeleli kwamakhoyili okushisa - ngokuvamile aphuka ngisho nalapho kushintsha amakhandlela.
Ukuvuza okupholile okuvela kuyunithi yepompo yamanzi enama-thermostat amabili. Isizathu silele ezintweni ezingalungile ze-gasket.
Injini enensayo ukufudumala. Inkinga enkulu isekhanda lesilinda.
Ukusebenza okunomsindo kweyunithi. Okuvame ukubonakaliswa ngesikhathi sokusheshisa nokunciphisa. Umthombo othize wenkinga awukaziwa.
Ukulondolozeka
Umbono ngokugcinwa uchazwe ngokucacile nguProfi VW waseMoscow: “... ukugcinwa - cha! Idizayini ye-modular, amamojula ashintsha imihlangano". Isekelwa iningi labanikazi bezimoto.
Ukulungisa kabusha kuyinkinga enkulu. I-crankshaft ayishintshwa ngokuhlukana, ihlanganiswa kuphela ne-block. Lokhu kusho ukuthi ezimweni eziningi akusizi ukwenza isicefe semikhono.
Ukulungiswa okuncane kungenzeka. Azikho izinkinga ngezingxenye ezisele. Kodwa uma kubhekwa izindleko eziphakeme zokubuyisela izinjini ezivuthayo zangaphakathi, abanikazi bezimoto abaningi bafika esinqumweni sokuthenga i-CMBA yenkontileka. Izindleko zayo zincike ku-mileage, ukuphelela kokunamathiselwe nezinye izici. Intengo yenjini "esebenzayo" iqala kusuka kuma-ruble ayizinkulungwane ezingama-80.
Injini yeVolkswagen CMBA iyonke kuvele ukuthi ingethembekile, ingaqediwe. Abanikazi bezimoto abaningi bafinyelela esiphethweni sokuthi kuhle ukuyishintsha kufakwe enye, injini yomlilo yangaphakathi enokwethenjelwa kakhudlwana.
