Nissan VK45DD, VK45DE izinjini
Okuqukethwe
Ukukhathazeka "Nissan" idume ukukhiqizwa isabelomali, kodwa imikhiqizo izinga eliphezulu kakhulu. Naphezu kwalokhu, emigqeni yemodeli yomkhiqizi kukhona nezimoto ezibizayo, eziphezulu noma zezemidlalo.
Kumamodeli anjalo, amaJapane aklama ngokuzimela futhi akhiqize ama-motor anokusebenza okuhle nezinga eliphezulu lokwethembeka. Namuhla sizokhuluma ngezinjini ezimbili ze-Nissan ezinamandla kakhulu - i-VK45DD ne-VK45DE. Funda kabanzi mayelana nomqondo, umlando wokudalwa kwazo kanye nezici zokusebenza ngezansi.
Mayelana nokwakhiwa nokudalwa kwezinjini
Ama-ICE abhekwa namuhla ebusweni be-VK45DD ne-VK45DE angena kuma-conveyors akwa-Nissan ngo-2001. Bakhiqizwa iminyaka engu-9, okungukuthi, ngo-2010, ukwakhiwa kwezinjini kwaphela. I-VK45DD kanye ne-VK45DE kuthathelwe indawo amayunithi aphelelwe yisikhathi kumamodeli amele kanye nezemidlalo okukhathazeka. Ukunemba kakhudlwana, amayunithi athathe indawo ye-VH41DD/E ne-VH45DD/E. Afakwe ikakhulukazi ku-Infiniti Q45, Nissan Fuga, President and Cima.
I-VK45DD ne-VK45DE ziyi-8-cylinder, izinjini zikaphethiloli ezinomklamo oqinisiwe namandla amakhulu ngokwanele. Ukuhlukahluka kwezinjini ezinomthamo wama-4,5 amalitha kanye nama-280-340 "amahhashi" aphuma ekukhululweni kokugcina. Umehluko phakathi kwe-VK45DD ne-VK45DE usezicini eziningana zokwakha, okuyilezi:
- I-Compression ratio - ku-VK45DD ingu-11, kanti ku-VK45DE isezingeni lika-10,5.
- Uhlelo lokunikezwa kwamandla - i-VK45DD inomphakeli oqondile ngaphansi kokulawulwa kweyunithi ekhethekile, kuyilapho i-VK45DE isebenzisa umjovo wamafutha enamaphuzu amaningi kumasilinda (i-injector evamile).
Kwezinye izici, i-VK45DD ne-VK45DE izinjini ezifanayo ngokuphelele ezakhiwe ngesisekelo se-aluminium block kanye nekhanda layo elijwayelekile le-Nissan.
Uma kuqhathaniswa nabangaphambi kwawo, lawa ma-motor anomklamo ocatshangelwe kakhudlwana futhi alula ngokuphawulekayo. Ngokuhamba kwesikhathi, i-VK45s yaphelelwa yisikhathi futhi yathathelwa indawo yizinjini zesimanje, ngakho kusukela ngo-2010 i-VK45DD ne-VK45DE ayizange ikhiqizwe. Ungahlangana nabo kuphela ngendlela yamasosha enkontileka, intengo yawo ephakathi kwama-ruble ayi-100-000.

Qaphela! Amayunithi okukhulunywa ngawo akhiqizwa kuphela ngesimo sikaphethiloli oshiswayo. Akunakwenzeka ukuhlangabezana nokwehluka okuhlukile kwamamotho ane-turbine noma izici ngaphandle kwalezo eziphawulwe ngenhla.
Ukulungisa kanye nensizakalo
I-VK45DD ne-VK45DE yizinjini ezinokwethenjelwa kakhulu, singathini ngensiza yazo emangalisayo. Amakhilomitha ayingxenye yesigidi sesigaba esiphezulu se-ICE esinamandla anjalo maningi ngempela. Kukhona ikhwalithi efanayo ngisho emikhiqizweni ye-Nissan ukukhathazeka njalo. I-VK45-x ayinawo amaphutha ajwayelekile, noma kunjalo, kubalulekile ukuhlola isici esisodwa somklamo ngaphambi kokuqala ukusebenza kwawo.
Sikhuluma ngama-catalysts angaphambili, avame ukucekelwa phansi ngenxa yokungabi bikho kukaphethiloli kanye nemithwalo ephezulu. I-ceramics yabo ingena kumasilinda futhi ibangele umonakalo ongalungiseki, odinga ukushintshwa okuphelele kwemoto. Ukuze uvimbele lokhu, kwanele ukuhlola njalo ama-catalysts, noma umane ubeke esikhundleni sawo ngokuvala amalangabi bese wenza ukulungisa ama-chip. Ngale ndlela kanye nokugcinwa okuhlelekile, izinkinga ze-VK45DD ne-VK45DE akufanele zivele.
Mayelana nokwenziwa kwesimanje kwalezi ziyunithi, kwamukelekile impela. Amandla amamotho okukhulunywa ngawo angama-350-370 amahhashi nama-280-340 amenyezelwe. Ukushuna i-VK45DD ne-VK45DE kwehla ekushintsheni ukwakheka kwazo. Ngokuvamile ngokwanele:
- ngcono camshafts;
- qinisa i-CPG;
- thuthukisa uhlelo lwe-exhaust;
- reflash "ubuchopho".
Ukukhwabanisa okunjalo kuzofaka "amahhashi" angu-30-50 ku-drain. Asikho isidingo sokufaka ama-turbines, ama-turbo kits namanye ama-supercharger kuma-VK45s. Lokhu akusizi kuphela mayelana nokusetshenziswa kwemali, kodwa futhi kuthinta kakhulu insiza yezinjini. Kunengqondo kakhulu futhi ukufunda nokubhala ukumane uguqule ukwakheka kwezinjini, uthole amandla amahhashi angama-30-50 aqinisekisiwe futhi angenazinkinga. Ibhonasi yinhle ngempela.
