Injini yeRenault G9U
Okuqukethwe
Onjiniyela baseFrance basungule futhi bafaka ekukhiqizeni enye iyunithi yamandla, esasetshenziswa kumabhasi amancane esizukulwane sesibili. Umklamo wabonakala ufunwa futhi wazuza ngokushesha uzwela lwabashayeli.
Incazelo
Ngo-1999, izinjini ezintsha (ngaleso sikhathi) zomndeni "G" zaqala ukuphuma emgqeni womhlangano we-Renault auto. Ukukhululwa kwabo kwaqhubeka kwaze kwaba ngu-2014. Injini ye-diesel ye-G9U yaba imodeli eyisisekelo. Ingu-2,5 litre in-line four-cylinder turbodiesel enamandla angu-100 kuya ku-145 hp ku-torque engu-260-310 Nm.
Injini yafakwa ezimotweni zakwaRenault:
- I-Master II (1999-2010);
- I-Traffic II (2001-2014).
Ngezimoto zakwa-Opel/Vauxhall:
- I-Movano A (2003-2010);
- I-Vivaro A (2003-2011).
Ezimotweni zakwaNissan:
- I-Interstar X70 (2003-2010);
- I-Primastar X83 (2003-2014).

Ukuthembeka, ubuthakathaka, ukugcina
Izici zobuchwepheshe zenjini zizophelela kakhulu uma izici eziyinhloko zokusebenza zinamathiselwe kuyo.
Ukuthembeka
Ekhuluma ngokuthembeka kwenjini yomlilo yangaphakathi, kubalulekile ukukhumbula ukubaluleka kwayo. Kuyacaca ukuthi imoto esezingeni eliphansi, engathembekile ngeke idume phakathi kwabanikazi bezimoto. I-G9U ayinawo la maphutha.
Enye yezinkomba eziyinhloko zokuthembeka yimpilo yesevisi yenjini. Eqinisweni, ngokulungiswa okufika ngesikhathi, idlula amakhilomitha ayizinkulungwane ezingama-500 we-mileage yamahhala yesondlo. Lesi sibalo asiqinisekisi kuphela ukuqina, kodwa futhi nokuthembeka kweyunithi yamandla. Kumele kukhunjulwe ukuthi akuzona zonke izinjini ezihambisana nalokho okushiwo. Futhi yingakho.
Ukuthembeka okuphezulu kweyunithi yamandla akuqinisekiswa hhayi kuphela ngezixazululo zokuklama ezintsha, kodwa futhi nezidingo zokugcinwa eziqinile. Ukweqa iminqamulajuqu kokubili ngokwemayela nebanga kanye nangesikhathi sokulungiswa okulandelayo kunciphisa kakhulu ukwethembeka kwenjini evuthayo yangaphakathi. Ukwengeza, umkhiqizi ubeka izidingo ezingeziwe kukhwalithi yezinto ezisetshenziswayo ezisetshenziswayo kanye namafutha kanye nezinto zokugcoba ezisetshenzisiwe.
Okubalulekile ezimweni zethu zokusebenza yizincomo zabashayeli abanolwazi nochwepheshe besevisi yemoto. Ikakhulukazi mayelana nokwehliswa kwezinsiza phakathi kwamasevisi. Ngokwesibonelo, batusa ukushintsha uwoyela hhayi ngemva amakhilomitha ayizinkulungwane 15 (njengoba kushiwo emithethweni yesevisi), kodwa ngaphambili, ngemva 8-10 amakhilomitha ayizinkulungwane. Kuyacaca ukuthi ngendlela enjalo yokulungiswa, isabelomali sizoncishiswa ngandlela-thile, kodwa ukwethembeka nokuqina kuzokhula kakhulu.
Isiphetho: injini inokwethenjelwa ngokulungiswa kwayo okufika ngesikhathi futhi okufanele.
Izindawo ezibuthakathaka
Mayelana namaphuzu abuthakathaka, imibono yabanikazi bezimoto iyahlangana. Bakholelwa ukuthi enjinini eziyingozi kakhulu yilezi:
- ibhande lesikhathi eliphukile;
- ukungasebenzi kahle kwe-turbocharger ehambisana nokugeleza kwamafutha ekungeneni;
- i-valve ye-EGR evaliwe;
- ukungasebenzi kahle kwezinto zikagesi.
Ochwepheshe besevisi yezimoto bengeza ukucekelwa phansi kwekhanda le-cylinder ngemva kokuzilungisa bebodwa. Ezimweni eziningi, lokhu kuwukuhlukana kwentambo ngaphansi kombhede wama-camshafts. Imishini kaphethiloli ayizange ishiywe ngaphandle kokunakwa. Ibuye ihluleke kaningi ngenxa yokungcoliswa uphethiloli we-diesel wezinga eliphansi.
Ake sithole ukuthi kungani lokhu kwenzeka nokuthi yini okufanele yenziwe ukuze kuqedwe lezi zinkinga.
Umkhiqizi unqume insiza yebhande lesikhathi kumakhilomitha ayizinkulungwane eziyi-120 wemoto. Ukweqa leli nani kuholela ekhefini. Umkhuba wokusebenzisa imoto ezimweni zethu, ezikude neYurophu, ubonisa ukuthi zonke izikhathi ezinconyiwe zokushintsha izinto ezisetshenziswayo zidinga ukuncishiswa. Lokhu kusebenza nasebhandeni. Ngakho-ke, ukushintshwa kwayo ngemva kwe-90-100 km eyizinkulungwane kuzokwandisa kakhulu ukuthembeka kwenjini futhi kuvimbele ukugwema ukulungiswa okuphawulekayo nokubizayo kwekhanda le-cylinder (ama-rockers aguqa uma kwenzeka ikhefu).
I-turbocharger iyinkimbinkimbi, kodwa indlela ethembekile. Ukugcinwa ngesikhathi kwenjini kanye nokushintshwa kwezinto ezisetshenziswayo (uwoyela, uwoyela kanye nezihlungi zomoya) kusiza ukusebenza kwe-turbine, eyandisa impilo yayo yenkonzo.
Ukuvaleka kwe-valve ye-EGR kunciphisa kakhulu amandla enjini evuthayo yangaphakathi, kuphazamisa ukuqala kwayo. Iphutha izinga eliphansi likaphethiloli wethu kadizili. Kulolu daba, umshayeli akanamandla okushintsha noma yini. Kodwa likhona ikhambi lale nkinga. Okokuqala. Kuyadingeka ukusula i-valve njengoba ivaleka. Okwesibili. Gcoba imoto emagalaji kaphethiloli agunyaziwe kuphela. Okwesithathu. Vala i-valve. Ukungenelela okunjalo ngeke kulethe umonakalo enjini, kodwa izinga lezemvelo lokukhishwa kwegesi ephumayo lizokwehla.
Amaphutha ezintweni zikagesi aqedwa ngochwepheshe benkonzo yezimoto ezikhethekile. Injini ingumkhiqizo wobuchwepheshe obuphezulu, ngakho yonke imizamo yokuxazulula inkinga ngokuhola kwakho, njengomthetho, ihluleke.
Ukulondolozeka
Izinkinga zokunakekela aziyona inkinga. I-Cast iron block ikuvumela ukuthi uthwale amasilinda kunoma yimuphi usayizi wokukhanda. Ngaphezu kwalokho, kukhona idatha ekufakweni kwamacala e-cartridge ku-block (ikakhulukazi, 88x93x93x183,5 ngekhola). I-Boring yenziwa ngaphansi kobukhulu bokukhanda be-piston, futhi ngesikhathi somkhono, izindandatho ze-piston kuphela ezishintshayo.
Ukukhethwa kwezingxenye ezisele nakho akunzima. Atholakala kunoma iyiphi i-assortment ezitolo ezikhethekile noma eziku-inthanethi. Lapho ukhetha izingxenye ezishintshayo, okuthandwayo kufanele kunikezwe ezangempela. Ezimweni ezingavamile, ungasebenzisa ama-analogues. Izingxenye ezisele ezisetshenzisiwe (kusuka ekudilizeni) akufanele zisetshenziselwe ukulungiswa, njengoba izinga lazo lihlala lingabaza.
Ukubuyiselwa kwemoto kufanele kwenziwe enkonzweni yemoto ekhethekile. Ezimweni "zegaraji", lokhu akufanele kwenziwe ngenxa yobunzima bokubuka inqubo yokulungisa. Isibonelo, ukuchezuka ku-torque yokuqinisa enconyiwe yomkhiqizi yokubopha imibhede ye-camshaft kubangela ukubhujiswa kwekhanda le-cylinder. Kunama-nuances amaningi afanayo enjini.
Ngakho-ke, ukulungiswa kwenjini kufanele kwenziwe ochwepheshe abanolwazi.
Ukuhlonza injini
Ngezinye izikhathi kuba nesidingo ukunquma ukwakheka kanye nenombolo motor. Le datha idingeka ikakhulukazi uma uthenga injini yenkontileka.
Kunabathengisi abangenanembeza abathengisa amalitha angu-2,5 esikhundleni sika-2,2 litre DCI. Ngaphandle, zifana kakhulu, futhi umehluko ngentengo cishe u-$ 1000. Uchwepheshe onolwazi kuphela ongakwazi ukuhlukanisa amamodeli enjini. Ukukhohlisa kwenziwa kalula - i-nameplate engezansi kwe-cylinder block iyashintsha.
Phezulu kwebhulokhi kunenombolo yenjini, engakwazi ukukhohlisa. Yenziwe ngezimpawu eziqoshiwe (njengasesithombeni). Ingasetshenziselwa ukunquma ivolumu yemoto ngokubheka idatha yomkhiqizi, esendaweni yomphakathi.
Indawo yamapuleti okuhlonza ingase yehluke kuye ngokuguqulwa kwenjini evuthayo yangaphakathi.
I-Renault G9U turbodiesel iyiyunithi ehlala isikhathi eside, ethembekile futhi eyongayo enokulungiswa okufika ngesikhathi kanye nekhwalithi ephezulu.
