PRODUCT NHUNGAMIDZO
Mercedes M270 peturu injini ine vhoriyamu 1.6 uye 2.0 malita akagadzirwa kubva 2011 kusvika 2019 uye akaiswa pamhando dzine injini inotenderera, senge A-kirasi uye B-kirasi. Mayuniti akafanana emota ane longitudinal injini indekisi M274.
R4 Mercedes injini: M102, M111, M133, M139, M166, M200, M254, M260, M264, M266, M270, M271, M274, M282.
Muna 2011, mutsara mutsva we 1.6 uye 2.0 litre peturu simba zvikamu zvakatanga, izvo zvakasiyana nepiston sitiroko, uye injini zvakare dzaive nesarudzo dzinoverengeka dzekusimudzira. Dhizaini yacho ndeyechimanjemanje: 4-cylinder aluminium block ine maoko esimbi uye bhachi rakavhurika rekutonhodza, aruminiyamu 16-vharuvhu silinda musoro ine hydraulic lifters, yakananga jekiseni jekiseni rine piezo jekiseni, chikamu chinochinja pamacamshafts maviri, an IHI AL0070 kana IHI AL0071 turbocharger ine air intercooler uye timing chain drive. Zvakare zvinocherechedzwa ndeye inosiyana yekuchinjisa mafuta pombi uye yemagetsi thermostat.
1.6-litre einjini inogadziridzwa yaive Option yakashongedzerwa neCamtronic intake system, uye 2.0-litre shanduro yaive neLanchester counterbalance mechanism yekudzikisa kuzunguzika.

Zvakaipa zve Mercedes M270 injini
Mune motors kusvika 2014, vagadziri vechikamu vakakurumidza kutadza uye vakatanga kutsemuka, ipapo vakagadziridzwa uye dambudziko rakatanga kuoneka gare gare, asi harina kunyangarika zvachose. Iyo ketani yenguva haina yakakwira sosi kana, kazhinji inoshandurwa yega yega 100-150 zviuru zvemakiromita.
Mune injini dzemhuri iyi, iyo impulse disk inotsikirirwa pane camshaft uye zvishoma nezvishoma inoshanduka nekutanga kwega kwega. Cheni yakatambanudzwa inonyanya kukurumidza kuita. Ndicho chikonzero nei pane dambudziko nekutanga injini kusvika pakukundikana kwakakwana.
Muna 2015, masimba emagetsi eiyi nhevedzano akagamuchira imwe firmware uye akawedzera hupfumi, asi anodaidzira kutsiviwa kwemapistoni akaparadzwa nekuda kwedetonation yakabva yanaya. Kunyangwe mafuta emhando yakaderera anoderedza zvakanyanya sosi yeakananga jekiseni piezo majekiseni.
Izvo zvinodikanwa kunyatso tarisisa mamiriro einotonhora sisitimu yeyuniti iyi, sezvo cylinder musoro pano inotungamira nekukurumidza uye kunyange kubva kune yakarebesa kupisa. Dambudziko iri rinowedzerwa nekuvapo kwete iyo yakavimbika thermostat uye pombi yemvura.
Kuvuza kunogara kuchisangana nekuda kwekukanganisa kweiyo yakanamatira crankcase ventilation valve, pamwe nekubva pasi pekupisa exchanger gasket kana kumberi kwe crankshaft mafuta chisimbiso. Nekuda kwekutyoka kwewaya, iyo inochinjika yepombi yepombi inorembera, hosi dzemafuta dzinodonhawo, turbine actuator inobata, uye adsorber inokurumidza kuvhara.
