I-ENJINI EGCWELELEYO ye: Injini iMercedes M274
IMVELISO INTSHAYELELO
Inkxalabo iye yavelisa iinjini zepetroli iMercedes M274 enomthamo we-1.6 kunye ne-2.0 ilitha ukususela ngo-2011 kwaye ifake kwiimoto ezinenjini yobude, njenge-C-class kunye ne-E-class. Iimoto ezifanayo kwiimodeli ezinolungiselelo olunqamlekileyo lweyunithi zinesalathisi se-M270.
Iinjini ze-R4 Mercedes: M102, M111, M133, M139, M166, M200, M254, M260, M264, M266, M270, M271, M274, M282.
NgoNovemba ka-2011, umgca omtsha we-1.6 kunye ne-2.0 ye-injini yepetroli yaqala ukuqala. Kukho ibloko ye-aluminiyam yeesilinda ezi-4 ezinelayini zentsimbi kunye nejacket yokupholisa evulekileyo, i-aluminiyam eyi-16-valve intloko yesilinda ene-hydraulic compensators, i-intake and exhaust dephasers, i-IHI AL0070 okanye i-IHI AL0071 turbine (kuxhomekeke kwinguqulo yenjini) i-intercooler yomoya, inkqubo yokutofa ngokuthe ngqo, umthamo wempompo ye-oyile eguquguqukayo kunye ne-time chain drive. Iinjini ze-2.0-litre zine-Lanchester balancer ukunciphisa ukungcangcazela.
Ukususela ngo-2018, iiyunithi zolu luhlu ngokuthe ngcembe zinika indlela kwiinjini zomgca we-M264 kwaye ngoku ziveliswa kuphela njengenxalenye yesityalo samandla esixubileyo se-GLE okanye i-E-Class model.

Ukungalungi kwe-injini ye-Mercedes M274
Kwii-injini kude kube ngu-2014, abalawuli besigaba baqala ukuqhekeka ngokukhawuleza, ngoko umenzi wagqiba ukuyila kwaye ubutyebi banda ukuya kwi-150 - 200 yeekhilomitha eziliwaka. Malunga nokubaleka okufanayo, ikhonkco lexesha liyakhutshwa kwaye abaninzi bayalitshintsha ngaxeshanye.
Abanini beemoto ezininzi ezineenjini zale ntsapho bakhalaza malunga nokuqala iingxaki kwaye esona sizathu siphambili kukufuduswa kwediski ye-impulse ngokubhekiselele kwi-axis ye-camshaft. Ngokuqhelekileyo oku kubonakaliswe yimpazamo kwi-sensor ye-camshaft.
Ngo-2015, ii-injini zolu chungechunge zaphuculwa kwaye zaba noqoqosho oluncinci, kodwa oku kwakhokelela ekuqhumeni rhoqo ngokutshatyalaliswa kweepiston. I-Piezo inaliti yokutofa ngokuthe ngqo nayo inengxaki yamafutha akumgangatho ophantsi apha.
Kuyimfuneko ukubeka iliso ngononophelo imeko yenkqubo yokupholisa yeyunithi yamandla, ekubeni intloko yebhloko inokukhokelela apha nokuba ingabi kude kakhulu. Ingxaki yenziwa mandundu kukungathembeki kakuhle kwe-thermostat kunye nempompo yamanzi.
Ukuvuza rhoqo kusenzeka phantsi kwesivalo sevalve ngenxa yevalve yokuphuma komoya yecrankcase encangathiweyo, kunye naphantsi kwetywina langaphambili le-oyile yecrankshaft okanye ngegasket yesitshintshi sobushushu. Ngenxa yokwaphuka kwiingcingo, ivalve yempompo yeoyile eguquguqukayo iyaba ngumkhenkce, i-adsorber ivaleka ngokukhawuleza, imibhobho yesibaso ihlala ivuza kunye ne-actuator kwi wedges ye-iturbine.
