5.7 hemi injini - nkhani zofunika kwambiri za unit

Injini ya 5.7 Hemi ndi ya gulu la mayunitsi opangidwa ndi Chrysler. Mawonekedwe a injini ndikuti ili ndi chipinda choyaka moto cha semicircular. The mankhwala a nkhawa American unayamba mu 2003 pa nthawi ya kuwonekera koyamba kugulu la galimoto "Dodge Ram" - anawonjezera ndi injini Magnum 5,9. Timapereka chidziwitso chofunikira kwambiri chokhudza iye.

5.7 Hemi injini - zambiri zofunika

2003 kugwirizana osati ndi kuyamba kwa "Dodge Rama", komanso ndi banja lonse la injini m'badwo wachitatu. Yoyamba inali injini yamafuta ya 8cc V5. cm / 654 l codenamed Mphungu. Idalowa m'malo mwa block ya Magnum V3 yotchulidwa koyambirira. Injini ya 5,7 Hemi idagwiritsidwa ntchito mumitundu ya Chrysler Dodge Durango, Charger, 8C, Magnum R/T, Jeep Grand Cherokee ndi Commander.

Injini yokhala ndi sitiroko zinayi mwachilengedwe ili ndi ma V-silinda asanu ndi atatu ndi mavavu awiri pa silinda imodzi. Dongosolo la masitima apamtunda amatengera nthawi ya OHV valve. Anabala 99,49 mm, sitiroko 90,88 mm, kusamuka 5 cc.

Mu zitsanzo zoyamba - mpaka 2009, chiwerengero cha psinjika chinali 9,6: 1. Kenako inali 10,5:1. Injini ya 5.7 Hemi idapangidwa pakati pa 340 ndi 396 hp. (254-295 kW) ndi torque 08-556 Nm/3,950-4,400 Kuchuluka kwa mafuta a injini kunali 6,7 l/l. Komanso, kulemera kwa unit anafika 254 makilogalamu.

Mapangidwe a injini 5.7 Hemi - ndi njira zotani zomwe zidagwiritsidwa ntchito?

 Injini ya 5.7 Hemi idakonzedwanso kuchokera pansi ndi chipika chakuya chachitsulo chokhala ndi jekete komanso ngodya ya silinda ya 90°. Mitundu ya Pre-2008 inali ndi mphete zokulirapo za 1,50 / 1,50 / 3/0mm, pomwe mitundu ya 2009 inali ndi phukusi la 1,20/1,50/3,0mm. 

Akatswiriwa adaganizanso zoika chitsulo chachitsulo chopangidwa ndi ductile, chomwe chinali ndi mabawuti anayi pagawo lililonse lalikulu. Camshaft idapangidwanso pamtunda wapamwamba kuti ichepetse kutalika kwa ma pushrods. Pachifukwa ichi, unyolo wanthawi ndi wautali komanso umakhala pakati pa mabanki a silinda.

Hemi 5.7 ilinso ndi mitu ya silinda ya aluminiyamu yodutsa, ma valve apawiri ndi ma spark plugs pa silinda. Chipinda chosalala chinapangidwanso ndi mashelufu kumbali zonse ziwiri, zomwe zinawonjezera mphamvu ya unit yoyendetsa. 

Zowongolera zomwe zimathandizira kuti injini igwire bwino ntchito

Kuwongolera koyamba kuyang'ana ndi camshaft. Iye ali ndi udindo wogwiritsira ntchito ma valve olowetsa ndi kutulutsa mpweya chifukwa cha zopondera zomwe zili muzitsulo za valve. Zigawo zofunika zimaphatikizaponso akasupe a valavu ya njuchi ndi matepi a hydraulic roller.

Okonzawo adasankhanso njira yotsekera ma silinda a Multi-Displacement System. Izi zinachititsa kuti mafuta azichepa kwambiri komanso achepetse mpweya wotulutsa mpweya. Tekinolojeyi imagwira ntchito potseka mafuta ku masilinda anayi - awiri aliwonse - ndikusiya mavavu olowera ndi otulutsa atatsekedwa, kuwongolera kutuluka kwamafuta kudzera pazitsulo zonyamula ma valve. Hemi 5.7 ilinso ndi cholumikizira chamagetsi chamagetsi.

Injini ya ntchito 5.7 Hemi

Pankhani ya mphamvu iyi, mavuto angabwere ndi kuthamanga kwa 150-200 km. Izi zimagwira ntchito ku zovuta zomwe zimagwirizanitsidwa ndi akasupe a valve osweka kapena kumamatira ndi kuwonongeka kwa ma lever odzigudubuza. Izi nthawi zambiri zimatsagana ndi zovuta zoyaka komanso kuyatsa kwa Check Engine. Kunyalanyaza zizindikirozi kungakhale chifukwa cha kulephera kwakukulu kwa camshaft kapena tinthu tachitsulo mu mafuta.

Kodi ndisankhe injini ya 5.7 hemi?

Ngakhale zofooka izi, injini ya 5.7 Hemi ndi yabwino, yokhazikika. Mbali imodzi yomwe imathandizira izi ndikuti ili ndi mapangidwe osavuta - palibe turbocharging yomwe idagwiritsidwa ntchito, yomwe idakulitsa kwambiri moyo wake wautumiki. Choyipa chake ndikugwiritsa ntchito mafuta ambiri - mpaka malita 20 pa 100 km.

Ndi kukonza pafupipafupi ndikusintha mafuta pa 9600 km iliyonse, injiniyo idzakubwezerani ndi ntchito yokhazikika komanso kulephera kochepa. Tiyeneranso kukumbukira kuti ntchito yoyenera ya unit mphamvu m'pofunika kugwiritsa ntchito mafuta ndi mamasukidwe akayendedwe akayendedwe a SAE 5W20.
