Injini yakwaFord engu-1.5 Ecoboost - iyunithi enhle?

Ekwakheni injini engu-1.5 Ecoboost, abakwaFord bafunde emaphutheni adlule. Kwasungulwa isistimu yokupholisa engcono, futhi iyunithi yaqala ukusebenza ngokuthula nangempumelelo kakhudlwana. Funda kabanzi mayelana neyunithi esihlokweni sethu!

Amadrayivu e-Ecoboost - yini okufanele ukwazi ngawo?

Amayunithi okuqala omndeni wakwa-Ecoboost akhiwa ngo-2009. Zihlukene ngokuthi zisebenzisa i-turbocharging kanye nomjovo kaphethiloli oqondile. Izinjini zikaphethiloli zathuthukiswa ukukhathazeka kanye nonjiniyela abavela ku-FEV Inc.

Zaziyini izinhloso zabakhi?

Inhloso yentuthuko bekuwukunikeza amandla kanye nemingcele ye-torque eqhathaniswa nezinguqulo ezishiwo ngokwemvelo ezinokususwa okukhulu kakhulu. Ukuqagela kwakufaneleka, futhi amayunithi e-Ecoboost abonakala ngokusebenza kahle kukaphethiloli, kanye namazinga aphansi amagesi abamba ukushisa nokungcola.

Ngaphezu kwalokho, ama-motor awadingi izindleko ezinkulu zokusebenza futhi aguquguquka kakhulu. Imiphumela yomsebenzi yahlolwa kahle kangangokuthi umkhiqizi waseMelika wamisa ukuthuthukiswa kobuchwepheshe be-hybrid noma idizili. Elinye lamalungu omndeni aziwa kakhulu yinjini engu-1.5 Ecoboost.

1.5 Injini ye-Ecoboost - ulwazi oluyisisekelo

Injini engu-1.5L Ecoboost isizoqala ukusebenza ngo-2013. Idizayini yeyunithi ngokwayo ifana kakhulu nemodeli encane ye-1,0-litre. Sikhuluma ngezinkinga ezihlobene nesistimu yokupholisa. Imodeli engu-1,6 litre ngokushesha yashintsha ngokuphelele iyunithi enephutha.

I-block iqukethe izixazululo eziyinhloko ezibonisa umndeni we-Ecoboost, isibonelo. umjovo kaphethiloli oqondile kanye ne-turbocharging. Injini yaqala ukusetshenziselwa amamodeli alandelayo:

• I-Ford Fusion;
• Ford Mondeo (kusukela ngo-2015);
• IFord Focus;
• Ford S-Max;
• Ford Kuga;
• I-Ford Escape. 

Idatha yobuchwepheshe - libonakala ngani iyunithi?

I-in-line, i-four-cylinder unit ifakwe isistimu kaphethiloli enomjovo wamafutha oqondile. Isigqoko sesilinda ngasinye singama-79.0mm kanti i-stroke ingu-76.4mm. Ukususwa kwenjini okuqondile kungu-1498 cc.

Iyunithi ye-DOHC inesilinganiso sokucindezela esingu-10,0:1 futhi iletha 148-181 hp. kanye ne-torque engu-240 Nm. Injini engu-1.5L Ecoboost idinga uwoyela wenjini engu-SAE 5W-20 ukuze isebenze kahle. Ngakolunye uhlangothi, umthamo wethangi ngokwawo ungamalitha angu-4,1, futhi umkhiqizo kufanele ushintshwe njalo ngamahora angu-15-12. km noma izinyanga eziyi-XNUMX.

Izixazululo zedizayini - izici zedizayini zenjini engu-1.5 Ecoboost

Injini engu-1.5 Ecoboost isebenzisa i-aluminium cylinder block enama-cast iron liners. Abaqambi bazinza ekwakhiweni okuvulekile - lokhu bekufanele kunikeze ukupholisa okusebenzayo. Konke lokhu kwahambisana ne-crankshaft yensimbi entsha sha enama-counterweights angu-4 nama-bearings angu-5.

Yiziphi ezinye izixazululo ezethulwe?

Ukuze uthole izinduku zokuxhuma, izingxenye zensimbi ezishisayo ezenziwe ngempuphu zazisetshenziswa. Kufanele futhi unake amapiston e-aluminium. Ziyi-hypereutectic futhi zimboze izigqoko zokuphela kwe-asymmetrical ukunciphisa ukungqubuzana. Abaqambi baphinde basebenzise i-crankshaft ye-short-stroke, ehlinzeka ngokususwa okuncane.

I-Ford iphinde yethula isiguquli esicindezelwe sezindlela ezintathu, esihlanganiswe nobunye ubuchwepheshe, okusho ukuthi iyunithi ayikhiqizi izinto eziningi ezingcolisayo. Ngenxa yalokho, injini engu-1.5 Ecoboost ihlangabezana nezindinganiso eziqinile ze-Euro 6 zemvelo. 

I-motor ifudumala ngokushesha futhi isebenza ngokuzinzile. Ngemuva kwalokhu kukhona izenzo ezibambekayo zabaklami

Ngokuphathelene nesici sokuqala, ukusetshenziswa kwekhanda lesilinda eliklanywe kabusha ngokuphelele le-aluminium eline-exhaust manifold ehlanganisiwe kwaba yisinqumo esibalulekile. Lokhu kuholela eqinisweni lokuthi ukushisa kwamagesi okukhipha umoya kushisa iyunithi yokushayela. Ngesikhathi esifanayo, izinga lokushisa eliphansi lomhwamuko lelula impilo ye-turbocharger.

Kumele kuqashelwe ukuthi ikhanda linama-valve angu-4 nge-cylinder ngayinye - i-exhaust engu-16 kanye nama-valve okuphuza angu-2. Aqhutshwa amakhava amavalvu akhiwe ngokufanelekile, ahlala isikhathi eside kuma-camshaft amabili angaphezulu. Imishini yokukhipha umoya neyokungenisa ifakwe isistimu yesikhathi yamavalvu eguquguqukayo eyakhiwe abaklami bakwaFord - ubuchwepheshe be-Twin Independent Variable Cam Timing (Ti-VCT). 

Ifana neyunithi engu-1.0li kanye nokusebenza kwenjini ethule

Njengoba kushiwo ngaphambili, injini engu-1.5 Ecoboost ifana kakhulu nemodeli engu-1.0. Lokhu kusebenza, isibonelo, ohlelweni lwesimanje lwe-camshaft drive, olubolekwe kuyunithi ye-cylinder emithathu yamandla amancane. 

Ngaphezu kwalokho, i-1.5L iphinde ibe nebhande lesikhathi elisebenza ngamafutha enjini. Lokhu kubangela izinga eliphansi lomsindo. Futhi kwenza sonke isakhiwo siqine kakhudlwana. Abaklami bemodeli yomndeni wakwa-Ecoboost baphinde bazinza empompini kawoyela eshintshashintshayo elawulwa nge-elekthronikhi, nayo eshayelwa ibhande likawoyela.

Inhlanganisela ye-turbocharging kanye nomjovo kaphethiloli oqondile kuqinisekisa ukusebenza okuphezulu.

Injini engu-1,5L Ecoboost iyonga. Lokhu kufinyelelwa ngokuhlanganisa ukusebenza okuphezulu kwe-Borg Warner low inertia turbocharger nevalve yokudlula kanye nesiqandisi sokupholisa amanzi siye emoyeni. Ingxenye yesibili yakhelwe ku-plastic intake manifold.

Isebenza kanjani? Isistimu yomjovo oqondile wengcindezi ephezulu ijova uphethiloli emakamelweni avuthayo ngokusebenzisa izijovo ezinezimbobo ezingu-6 ezifakwe ekhanda lesilinda phakathi nendawo yesilinda ngayinye eduze kwamapulaki ezinhlansi. Ukusebenza kwezinto ezisetshenziswayo kulawulwa i-Drive-by-Wire electronic throttle kanye nesilawuli se-Bosch MED17 ECU. 

Ukusebenzisa injini engu-1.5 Ecoboost - izindleko ezinkulu?

I-Ford idale idrayivu ezinzile engadingi izindleko eziphezulu. Abasebenzisi bayayithokozela injini engu-1.5 Ecoboost ngenxa yokungabikho kwezinkinga ezihlobene nokusebenza kwesistimu yokupholisa - amaphutha enziwe ngesikhathi kuthuthukiswa imodeli engu-1.6L alungisiwe - injini ayishisi ngokweqile. Ngenxa yalokhu, kokubili i-turbocharger kanye nesiguquli se-catalytic akuhluleki.

Ekugcineni, ake sinikeze amathiphu ambalwa. Ukuze usebenze kahle iyunithi, kuyadingeka ukusebenzisa uphethiloli wekhwalithi ephezulu. Lokhu kuyadingeka ukugcina ama-injection esesimweni esihle - ngaphandle kwalokho angacinana futhi amadiphozithi akheke ezindongeni ezingemuva zamavalvu okungenisa. Impilo yonke yesevisi yeyunithi evela ku-Ford brand ingu-250 km. km, nokho, ngokulungiswa okuvamile, kufanele isebenzise leli mayela ngaphandle kokulimala okukhulu.
