Injini yeVolkswagen CZTA
Okuqukethwe
Le yunithi yamandla yadalelwa imakethe yaseMelika ngokukhethekile. Isisekelo sokuthuthukiswa kwakuyinjini ye-CZDA, eyaziwa kakhulu kubashayeli baseRussia.
Incazelo
Ulayini we-EA211-TSI (CHPA, CMBA, CXCA, CZCA, CZEA, CZDA, CZDB, CZDD, DJKA) ugcwaliswe ngenye injini, ebizwa nge-CZTA. Ukukhiqizwa kwayo kwaqala ngo-2014 futhi kwaqhubeka iminyaka emine, kwaze kwaba ngu-2018. Ukukhululwa kwenziwa embonini yezimoto eMlada Boleslav (Czech Republic).
Izinguquko eziyinhloko zenziwa ezinhlelweni zokupholisa, ipheshana lokungenisa ukwakheka kwengxube yokusebenza kanye namagesi okukhipha umoya. Lokhu kuthuthukiswa kuholele ekwehleni kwesisindo senjini sisonke kanye nokusetshenziswa kukaphethiloli ngendlela eyongayo.
Lapho uklama injini yomlilo yangaphakathi, zonke izithiyo ezikhona zezinjini ezikhiqizwa ngaphambili zohlobo olufanayo zazibhekwa. Abaningi baqedwa ngempumelelo, kodwa abanye basala (sizokhuluma ngabo kamuva).
Umqondo wokuklama jikelele uhlala ufana - umklamo we-modular.
I-CZTA iyiyunithi kaphethiloli engu-1,4-litre in-line engamacylinder amane enamandla angu-150 hp. ene-torque engu-250 Nm efakwe i-turbocharger.
Injini yafakwa ku-VW Jetta VI 1.4 TSI "NA", yathunyelwa eNyakatho Melika kusukela ngo-August 2014. Ngaphezu kwalokho, ilungele ukuhlomisa ezinye izinhlobo zeVolkswagen - Passat, Tiguan, Golf.
Njengozakwabo, i-CZTA ine-aluminium cylinder block ene-cast iron liners. I-crankshaft engasindi, amapiston nezinduku zokuxhuma.
Ikhanda le-Aluminium cylinder, elinamavalvu angu-16 afakwe izinxephezelo ze-hydraulic. Umbhede wama-camshafts amabili unamathiselwe phezulu kwekhanda, lapho abalawuli besikhathi se-valve bafakwa khona. Isici - inhloko yesilinda isetshenziswe ngo-180˚. Ngakho-ke, i-exhaust manifold ingemuva.
Ukushaja okuphezulu kwenziwa yi-IHI RHF3 turbine ene-overpressure ye-1,2 bar. Isistimu ye-turbocharging ibhangqwe ne-intercooler efakwe kubuningi bokudla. Umthombo we-turbine ungamakhilomitha ayizinkulungwane ezingu-120, ngokulungiswa okwanele nokusebenza okulinganiselwe kwemoto, inakekela amakhilomitha angaba ngu-200.
Isikhathi sokushayela ibhande. Umkhiqizi uthe i-mileage ye-120 km eyizinkulungwane, kodwa ezimweni zethu kunconywa ukuthi ushintshe ibhande ngaphambili, ngemva kwe-90 km. Ngesikhathi esifanayo, zonke izinkulungwane ze-30 km, kuyadingeka ukuqapha ngokucophelela isimo sebhande, ngoba uma kwenzeka ikhefu, ama-valve akhubazekile.
Isistimu yamafutha - injector, umjovo osakazwayo. Kusetshenziswa uphethiloli we-AI-98.
Injini izwela kakhulu izinga likaphethiloli. Idizayini yenjini evuthayo yangaphakathi ivumela ukufakwa kwesizukulwane sesine se-HBO, isibonelo, i-KME NEVO SKY enebhokisi legiya le-KME Silver kanye namabhomu e-Barracuda.
Uhlelo lokuthambisa lusebenzisa uwoyela i-0W-30 ngokuvunywa nokucaciswa kwe-VW 502 00 / 505 00. Ngaphezu kokugcotshwa, imibhobho kawoyela ipholisa imiqhele yepiston.
Isistimu yokupholisa yohlobo oluvaliwe, i-double-circuit. Iphampu nama-thermostat amabili atholakala kuyunithi ehlukile.
Injini ilawulwa yi-ECM ene-Bosch Motronic MED 17.5.21 ECU.

Ukuthembeka, ubuthakathaka, ukugcina
Ukuthembeka
Ukuthembeka kwe-CZTA akungabazeki. Ukuqinisekisa lokhu kuwumthombo wenjini. Umkhiqizi wamemezela kufika ku-300 ayizinkulungwane km, kodwa ekusebenzeni kuphezulu kakhulu. Isimo kuphela ukusetshenziswa kwamafutha ekhwalithi ephezulu kanye nezinto zokugcoba kanye nesevisi efika ngesikhathi.
Iyunithi inomkhawulo ophezulu wokuphepha. Ukushuna kwe-chip okulula nge-Stage1 firmware kwandisa amandla abe ngu-175 hp. Nge. I-torque nayo iyanda (290 Nm). Ukwakhiwa kwenjini kukuvumela ukuthi ukhulise amandla ngokuqhubekayo, kodwa akufanele uthathwe yilokhu.
Ukuphoqelela ngokweqile kubangela ukuguga okukhulayo kwezingxenye zezimoto, okuholela ekunciphiseni kwezinsiza kanye nokubekezelelana kwamaphutha. Ukwengeza, izici zenjini yomlilo yangaphakathi azishintshi zibe ngcono.
Ukwethenjelwa kuthuthukiswa ngokushintsha izingxenye ezivela kwezinye izinjini zohlobo olufanayo, njenge-CZCA noma i-CZDA.
U-Kein94 wase-Brest wazisa ukuthi ngenkathi ezama ukufaka esikhundleni sophenyo lwe-lambda, waba nenkinga ngokukhetha kwakhe. Okwangempela (04E 906 262 EE) kubiza 370 bel. ruble (154 c.u.), kanye nomunye, futhi VAGovsky (04E 906 262 AR) - 68 Bel. ama-ruble (28 c.u.). Ukukhetha kwawela kokugcina. Umphumela uba imayela elincishisiwe legesi futhi isithonjana sephutha kudeshibhodi siphumile.
Izindawo ezibuthakathaka
Iphuzu elibuthaka kakhulu i-turbine drive. Kusukela endaweni yokupaka isikhathi eside noma ukushayela ngesivinini esingaguquki, induku ye-actuator ye-wastegate iyagcotshwa, bese i-actuator ye-wastegate iphukile.
Ukungasebenzi kahle kwenzeka ngenxa yephutha ezibalweni zobunjiniyela lapho kwakhiwa injini evuthayo yangaphakathi.
I-node ebuthaka imojula ye-pump-thermostat kusistimu yokupholisa. Lezi zakhi zifakwe kubhulokhi evamile. Uma kwenzeka ukwehluleka kwanoma iyiphi yazo, yonke imojula kufanele ishintshwe.
Ukulahleka kwenjini. Ngokuvamile kuba umphumela wenduku ye-actuator ejamekile. Isizathu esiqondile singatholakala lapho kuxilonga injini esiteshini sesevisi.
Ama-valve agobile lapho ibhande lesikhathi liphuka. Ukuhlolwa ngesikhathi kwebhande kuzovimbela ukuvela kokungasebenzi kahle.
Ukuzwela kuphethiloli. Uma usebenzisa uphethiloli namafutha wekhwalithi ephansi, ukupheka kwesamukeli samafutha nama-valve kwenzeka. Ukungasebenzi kahle kubangelwa isishisi samafutha.
Ukulondolozeka
I-CZTA ibonakala ngokugcinwa okuphezulu. Okokuqala, lokhu kwenziwa lula ukwakheka kweyunithi yeyunithi. Ukushintsha ibhulokhi enephutha emotweni akunzima. Kodwa lapha kufanele kukhunjulwe ukuthi ezimweni zegaraji akulula ukwenza lokhu.
Ayikho inkinga yokuthola izingxenye ozidingayo ukuze zilungiswe. Naphezu kweqiniso lokuthi le injini ayizange ithole ukusabalalisa okubanzi ezweni lakithi (yakhiwe e-USA), izingxenye nezingxenye zokubuyiselwa kwayo zitholakala cishe kuzo zonke izitolo ezikhethekile.
Njengoba kunikezwe izindleko eziphakeme zezingxenye ezisele kanye nokuzilungisa ngokwakho, ungasebenzisa enye inketho - ukuthenga injini yenkontileka. Kulokhu, udinga ukulungele ukukhokha ruble mayelana 150 ayizinkulungwane ukuthenga.
Kuye ngokucushwa kwe-motor enezinamathiselo nezinye izici, ungathola injini yomlilo yangaphakathi eshibhile.
