Injini yakwaMercedes M112
Okuqukethwe
Injini yakwaMercedes M112 iyinjini engu-V6 kaphethiloli, eyethulwa ngoMashi 1997 ku-E-class ngemuva kweW210 (Izinjini ze-W210). Ushintshe injini M104.
Ulwazi General
Injini ye-M112 ihlobene kakhulu ne-M8 V113. Ngokwengxenye enkulu, zenziwa ezindaweni ezifanayo zokukhiqiza futhi zinezingxenye eziningi ezifanayo. Zombili zine-alloy cylinder block enama-cast liners enziwe nge-Silitec (Al-Si alloy). Injini ifakwe i-camshaft eyodwa kumugqa ngamunye wamasilinda. Ngenhla kwe-crankshaft kune-balance shaft ezungeza i-crankshaft ngesivinini esifanayo ukuze inciphise ukudlidliza.
Ama-camshafts ne-balancer shaft aqhutshwa ngochungechunge lwama-roller amabili. Njenge-M113, i-M112 inama-valve amabili okudla kanye ne-valve eyodwa yokukhipha nge-cylinder, eqhutshwa ngamarocker rocker light nge-hydraulic slack adjuster.
Ukusetshenziswa kwe-valve eyodwa yokukhipha kuholela endaweni ethekwini elincane lokukhipha futhi ngaleyo ndlela ukushisa okukhipha kancane kudluliselwe ekhanda lesilinda, ikakhulukazi lapho injini ibanda. Ngakho-ke, i-catalyst ifinyelela izinga layo lokushisa ngokushesha. Lokhu kusiziswa nayizinqwaba zamashidi wensimbi emincane enezindonga ezimbili, ezithatha ukushisa okuncane.
Ikamelo ngalinye lomlilo linama-plugs amabili kwesokudla nakwesobunxele se-valve yokukhipha. Ukuhlelwa kwama-valve nama-plugs kuyalingana. Ngenxa yokushisa kabili, umthwalo wokushisa ku-piston uyanda, upholiswa yimibhobho kawoyela, ujova uwoyela wenjini kusuka ngezansi kuye ekhanda le-piston.
Injini engu-M112 yakhiqizwa ngevolumu engu-2,4 kuya ku-3,7 litres. Sizocubungula ukuguqulwa ngemininingwane eminingi engezansi.
Ngo-2004, kwafakwa uM112 esikhundleni sakhe Injini ye-M272.

Izinkinga zenjini iMercedes M112
Inkinga enkulu yale njini ukusetshenziswa kukawoyela, lokhu kungenxa yezici eziningi:
- uhlelo lokuphinda usebenzise i-crankcase gas luvalekile, uwoyela uqala ukukhipha phakathi kwama-gaskets nezimpawu (ngokusebenzisa amashubhu we-crankcase ventilation, uwoyela nawo uqala ukucindezela ezinhlwini zokudla);
- ukushintshwa okungalindelekile kwezimpawu zama-valve stem;
- ukugqoka amasilinda namasongo okususa uwoyela.
Kudingeka futhi ukuqapha ukwelula iketango (insiza mayelana 250 ayizinkulungwane km). Uma ubona ngokuhamba kwesikhathi, esikhundleni seketango (kukhona ezimbili) kuzobiza kusuka kuma-ruble ayizinkulungwane ezingu-17 kuya ku-40, kuye ngokuthi izindleko zezingxenye ezisele. Kubi kakhulu uma uphuthelwa isikhathi sokugqoka - kulokhu, izinkanyezi ze-camshaft kanye ne-chain tensioner ziphela, ngokulandelana, ukulungiswa kuzobiza izikhathi eziningana.
Ukushuna uM112
Ukushuna kwesitoko okufiswa ngokwemvelo i-M112 ekuqaleni akunanzuzo, ngoba ukwenyuka okukhulu ngesabelomali esincane akukwazi ukutholwa, futhi ukuthuthuka okukhulu kubiza kakhulu kangangokuba kube lula ukuthenga imoto enenjini esevele icindezele.
Noma kunjalo, kunamakhithi we-compressor avela enkampanini iKleemann, enzelwe lezi zinjini ngqo. Ngemuva kokufaka i-kit + firmware, ungafika ku-400 hp kokukhiphayo. (enjini engu-3.2 litre).
