Mercedes-Benz M275 injini

Ma injini a M275 adalowa m'malo mwa M137 yosatha. Mosiyana ndi kuloŵedwa m'malo, injini latsopano ntchito masilindala ndi awiri ang'onoang'ono, njira ziwiri kwa kufalitsidwa ozizira, ndi bwino mafuta ndi kulamulira dongosolo ME 2.7.1.

Kufotokozera kwa injini za M275

injini M275

Choncho, kusiyana kwa injini yatsopano yoyaka mkati ndi motere:

• miyeso ya masilindala mu circumference anachepetsedwa 82 mm (pa M137 anali 84 mm), zomwe zinachititsa kuti kuchepetsa voliyumu ntchito kwa malita 5,5 ndi thicken ufulu danga pakati pa zinthu za CPG;
• kuwonjezeka kwa magawowo, kunapangitsa kuti pakhale njira ziwiri zoyendetsera antifreeze;
• dongosolo loipa la ZAS, kutseka ma silinda angapo pa injini yopepuka ndikuwongolera mawonekedwe a camshaft, kwathetsedwa;
• makina oyendetsera injini yamagetsi asinthidwa ndi mtundu wamakono;
• DMRV inathetsedwa - owongolera awiri adagwiritsidwa ntchito m'malo mwake;
• adachotsa ma probe 4 a lambda, omwe adapereka mphamvu zambiri ku injini;
• kuti pakhale kayendetsedwe kabwino ka mafuta, pampu yamafuta idaphatikizidwa ndi gawo lowongolera ndi fyuluta yosavuta - pampu yamafuta osayendetsedwa idayikidwa pa M137, kuphatikiza sensa yophatikizika;
• chotenthetsera kutentha mkati mwa cylinder block chinachotsedwa, ndipo radiator wamba idayikidwa pamalo ake kutsogolo;
• centrifuge yawonjezeredwa ku dongosolo lotulutsa mpweya;
• kukanikiza kunachepetsedwa mpaka 9.0;
• chiwembu chinagwiritsidwa ntchito ndi ma turbines awiri ophatikizidwa muzowonjezera zotayira - mphamvuyi imakhazikika ndi njira ziwiri zomwe zili pamwamba pa mutu wa silinda.

Komabe, M275 imagwiritsa ntchito mawonekedwe omwewo a 3-valve omwe adagwira ntchito bwino pa M137.

Werengani zambiri za kusiyana pakati pa injini za M275 ndi M137.

Makina a injini ya M275

Tsopano za machitidwe a injini yatsopano.

1. Kuyendetsa nthawi unyolo, mizere iwiri. Pofuna kuchepetsa phokoso, mphira amagwiritsidwa ntchito. Zimakwirira parasitic ndi crankshaft sprockets. Hydraulic tensioner.
2. Pampu yamafuta ndi magawo awiri. Imayendetsedwa ndi unyolo wosiyana wokhala ndi kasupe.
3. Dongosolo lamagetsi lamagetsi lamagetsi silili losiyana kwambiri ndi mtundu wa ME7 womwe umagwiritsidwa ntchito pamayendedwe ake. Zigawo zazikuluzikulu akadali gawo lapakati ndi ma coils. Dongosolo latsopano la ME 2.7.1 limatsitsa zidziwitso kuchokera ku masensa anayi ogogoda - ichi ndi chizindikiro chosinthira PTO kupita pakuyatsa mochedwa.
4. Dongosolo lowonjezera limalumikizidwa ndi kutulutsa. Ma compressor amasinthidwa pogwiritsa ntchito zida zopanda mpweya.

Injini ya M275 imapangidwa mu mawonekedwe a V. Ndi imodzi mwamagawo opambana a silinda khumi ndi awiri, yoyikidwa bwino pansi pamoto wagalimoto. Chotchinga cha motor chimapangidwa kuchokera ku zinthu zopepuka zokanira. Poyang'ana mwachindunji, zikuwoneka kuti mapangidwe a injini yoyaka mkati ndizovuta kwambiri kupanga ma mayendedwe ambiri ndi mapaipi operekera. M275 ili ndi mitu iwiri ya silinda. Amapangidwanso ndi zinthu zamapiko, ali ndi ma camshaft awiri aliwonse.

Ambiri, injini M275 ali ubwino zotsatirazi pa kuloŵedwa m'malo ndi injini zina kalasi ofanana:

• kukana bwino kutenthedwa;
• phokoso lochepa;
• zizindikiro zabwino kwambiri za mpweya wa CO2;
• kulemera kochepa ndi kukhazikika kwakukulu.

Turbocharger

Chifukwa chiyani turbocharger idayikidwa pa M275 m'malo mwa makina? Choyamba, adakakamizika kuchita ndi zochitika zamakono. Ngati m'mbuyomu panali kufunika kwa makina opangira ma supercharger chifukwa cha chithunzi chabwino, lero zinthu zasintha kwambiri. Kachiwiri, okonza anatha kuthetsa vuto la mayikidwe yaying'ono injini pansi pa nyumba - ndipo iwo ankaganiza choncho - turbocharger amafuna malo ambiri, kotero unsembe pa injini m'munsi n'zosatheka chifukwa cha masanjidwe mbali.

Ubwino wa turbocharger umawoneka nthawi yomweyo:

• kuwonjezereka kofulumira kwa kuthamanga ndi kuyankha kwa injini;
• kuchotsa kufunikira kolumikizana ndi dongosolo lopaka mafuta;
• mawonekedwe osavuta komanso osinthika omasulidwa;
• palibe kutaya kutentha.

Kumbali inayi, dongosolo loterolo silikhala ndi zovuta zake:

• ukadaulo wokwera mtengo;
• kuvomerezedwa kosiyana kuzirala;
• kukula kwa injini.
