Injini yeRenault L7X
Okuqukethwe
Ukuze ungene esikhundleni solayini wenjini ye-PRV ophelelwe yisikhathi, abakhi bezinjini baseFrance bahlongoze i-ESL entsha. Izibulo kulo mndeni kwakuyiyunithi yamandla L7X.
Incazelo
Injini yathuthukiswa onjiniyela bakwaRenault kanye nongoti bakwaPeugeot-Citroen ngo-1997. Ukukhiqizwa kwenziwa esitshalweni saseDouvrin (eFrance).
I-L7X ingu-3,0-litre V-twin injini kaphethroli ekhiqiza u-190 hp. netorque engu-267 Nm.
Ifakwe kwaRenault Safrane, Laguna, Espace kanye nezimoto "ezishajiwe" ze-Clio V6. Ngaphansi kwenkomba engu-ES9J4, ingatholakala ngaphansi kwe-hood ye-Peugeot (406, 407, 607 kanye ne-807), nangaphansi kwenkomba XFX / XFV ku-Sitroen XM ne-Xantia.
I-cylinder block nekhanda le-cylinder zenziwe nge-aluminium alloy. Imikhono yensimbi.
Ikhanda le-cylinder linama-camshaft amabili nama-valve angu-12. Amashafu okuthatha afakwe ama-phase shifters kusukela ngo-2000.
I-Timing belt drive nge-mechanical tensioner roller (kuze kube ngu-2000 bekuyi-hydraulic). Insiza 120 ayizinkulungwane km, kodwa kungcono ukuyishintsha ngaphambili.
Isici ohlelweni lokupholisa iphampu. Ngaphambi kokuhlomisa i-motor nge-shifter yesigaba, izinhlobo ezimbili zamaphampu wamanzi zazisetshenziswa, ezihlukene ngobubanzi bezimbobo ezifakwayo (73 kanye no-63 mm).
Injini ethuthukisiwe yafakwa kwi-Clio V6 (bheka ithebula). Ngaphambi kokulungiswa kabusha, amandla ayo ayengama-230 hp. s, kunguqulo ye-post-styling - 255.

Kusho ukuthini ukuguqulwa?
Phakathi naso sonke isikhathi sokukhiqiza, injini iye yathuthukiswa ngokuphindaphindiwe. Izinguquko zithinte okunamathiselwe kanye nokuqiniswa kwazo. Ingxenye engumshini yahlala ingashintshiwe. Okuhlukile yiClio V6 kanye neVenturi 300 Atlantique, eyayinenjini eyi-turbocharged.
Izinguquko ezamukelwe amakhoyili ane-voltage ephezulu. Ikhoyili ephindwe kathathu (ejwayelekile) ishintshiwe kwafakwa amakhoyili ngamanye.
Ama-motor mounts ashintshiwe ngokuhambisana nemodeli yemoto afakwe kuyo.
Imininingwane ayishintshile.

Ukuthembeka, ubuthakathaka, ukugcina
Ukuthembeka
Ngokusho kochwepheshe besevisi yemoto kanye nokubuyekezwa kwabanikazi bezimoto, imoto inokwethenjelwa futhi ayinakuzithoba. Kufanele sikhokhe intela, ekuqaleni abaningi babenezinkinga ngesikhathi. Kodwa lokhu kwakungeyona i-miscalculation eyakhayo, kodwa ukungazi okuyisisekelo kwezici ze-L7X.
Ngokuya ngemithetho yesondlo kanye nokugcwaliseka kwezidingo zomkhiqizi, injini yeqa kakhulu insiza eshumekwe kuyo.
Izindawo ezibuthakathaka
Awekho amaphuzu aqinile abuthakathaka kuyunithi. Kube nezimo zokuhluleka kukagesi ngenxa yokuxhumana okufakwe i-oxidized kanye nokulahlekelwa okuyisisekelo kwama-chips avela kuzixhumi.
Ibhande lesikhathi lidinga ukunakwa okukhethekile. Ukwanda kwempilo yayo yesevisi kusongela ukuphuka, futhi, ngenxa yalokho, ukulungiswa okukhulu noma ukushintshwa kwenjini.
Injini ayikwazi ukuma ngisho nokushisa okwesikhathi esifushane. Ibhulokhi yesilinda, ikhanda lesilinda kanye nekhompyutha esebhodini kuyahluleka. Ukuqapha njalo ukusebenza kwenzwa yokushisa, i-thermostat kanye nokuqapha okuyisisekelo kwamadivayisi phakathi nohambo kuqeda ngokuphelele amathuba okushisa ngokweqile.
Ukulondolozeka
I-motor ibhekwa njengelungisekayo. Ukungabaza kulolu daba kubangelwa i-aluminium cylinder block. Ngomonakalo wangaphakathi, awukwazi ukulungiswa.
Azikho izinkinga ngezingxenye ezisele ezitolo ezikhethekile. Kodwa amanani kwezinye zazo ngezinye izikhathi aphakeme kakhulu. Isibonelo, ibhande lesikhathi libiza phakathi kuka-$300 no-$500. Ukushintshwa kwayo nakho akushibhile. Kwamanye amamodeli ezimoto, injini kufanele isuswe ukuze kufakwe enye esikhundleni sayo.
Ngakho-ke, ngaphambi kokuqala ukulungisa, udinga ukuhlaziya ngokucophelela izindleko ezingenzeka. Kungase kwenzeke ukuthi inketho yokuthenga injini yenkontileka (intengo ephakathi kwama-ruble ayizinkulungwane ezingu-60) iyoba eyamukelekayo kakhulu.
Izibulo lochungechunge lwe-ESL L7X liphumelele futhi lithembekile. Kodwa kuncike ekusetshenzisweni kwazo zonke izincomo zomenzi ngokulungiswa nokusebenza kwayo.
