Nissan VQ30DET injini

Muna 1994, Nissan yakagadzira mutsara webhizinesi rekirasi sedans. Ivo vakagadzirwa neinjini dzeVQ dzakatevedzana dzine humburumbira inokwana 2, 2.5 uye 3 malita. Mota dzaive dzakanaka, asi dzisina kukwana. Kuitira hanya kweJapan kwakavavandudza zvishoma nezvishoma. Semuenzaniso, kuderedza uremu, iyo cast-iron cylinder block yakagadzirwa nealuminium, uye bhandi renguva pfupi rakatsiviwa neketani, iyo yakawedzera zvakanyanya hupenyu hwayo hwebasa.

Gare gare, mugadziri akasarudza kusiya hydraulic lifters. Izvi zvaive zvakakosha kuti kuwedzere kutengesa kunze kwemotokari kwakavakirwa painjini iyi kune nyika uko mafuta echicherwa akachipa aishandiswa zvakanyanya. Kushandiswa kwavo pamainjini ane hydraulic compensators kwakatungamirira kukukundikana kwekupedzisira.

Ipapo ivo vakavandudza iyo yekudyara uye exhaust system, vakaisa 2 camshafts padivi pemota. Zvose izvi zvakakonzera kuwedzera kwesimba uye torque yesimba remagetsi, uye kuwedzera kucheneswa kwemakamuri kwakaisa mukana wekumanikidza. Nekuda kweizvozvo, shanduko nyowani yakaonekwa - VQ30DET. Yakanga yatoshandiswa muna 1995 uye yakatoshandiswa pamotokari dze2008 (Nissan Cima).

Hunhu uye decoding yezita

Mazita emhando uye mhando dzeNissan injini dzinojekesa maitiro avo. VQ30DET inomirira:

1. V - kusarudzwa kwechimiro (munyaya iyi, tinoreva V-shaped structure).
2. Q ndiro zita renhevedzano.
3. 30 - humburumbira vhoriyamu (30 cubic dm. kana 3 litita).
4. D - kusarudzwa kweinjini dzine 4 mavharuvhu pahumburumbira.
5. E - multi-point electronic peturu jekiseni.

Izvi zvinoita kuti zvive pachena iwo ekutanga ma paramita emota.

Mota dzine VQ30DET injini

Iyi shanduko inoshandiswa nemichina inotevera:

1. Nissan Cedric 9 uye 10 zvizvarwa - kubva 1995 kusvika 2004.
2. Nissan Cima 3-4 zvizvarwa - kubva 1996 kusvika 2010.
3. Nissan Gloria 10-11 zvizvarwa - kubva 1995 kusvika 2004.
4. Nissan Leopard 4 zvizvarwa - kubva 1996 kusvika 2000.

Mazhinji emota idzi, kusanganisira ye1995 Nissan Cedric, ichiri munzira yakatsiga nekuda kwekuvimbika uye hupenyu hurefu hweinjini.

Nissan Cedric muna 1995

Neo tekinoroji

Muna 1996, Mitsubishi kunetseka yakatanga uye yakatanga kugadzirwa kwemainjini neGDI system. Chimiro cheinjini dzinopisa dzemukati dzakadai jekiseni rakananga repeturu mumasilinda pasi pekumanikidzwa kwakanyanya uye nemhepo yakawanda mumusanganiswa (reshiyo 1:40). Nissan yakaedza kubata nemukwikwidzi wayo wakananga uye yakatanga kugadzira tekinoroji yakafanana yejekiseni remafuta. Akatevedzana einjini ane yakananga mafuta jekiseni mumakamuri akagamuchira prefix kuzita - Neo Di.

Chinhu chikuru chegadziriro ndeyekumanikidza kwemafuta pombi. Kutenda kwaari, pakusashanda, kudzvanywa kwe60 kPa kunogadzirwa, uye paunenge uchityaira, inogona kukwira kusvika 90-120 kPa.

Injini dzemhuri yeDE dzakapfuura ichi chimanjemanje uye kubvira 1999 vakasanganisira mhando neNEO tekinoroji. Ivo vaive vakashongedzerwa camshafts uye nguva yevhavha. Aya ma motors ave akawedzera tekinoroji uye ane hushamwari kwezvakatipoteredza, asi panguva imwecheteyo basa ravo rainyanya kutsamira pakutonga kwemagetsi. Simba remagetsi emagetsi rakaramba rakafanana, asi kukanganisa kwavo kune zvakatipoteredza kwakaderera.

Kusashanda uye matambudziko enjini yeVQ30DET

Zvakataurwa pamusoro apa kuti shanduko iyi haina ma hydraulic lifters, saka kamwe chete pamakiromita zviuru zana zvakakosha kugadzirisa mavharuvhu - ichi chimiro chekugadzira chesimba iri.

Pane zvichemo paInternet kubva kune varidzi vemotokari vane injini idzi pamusoro pekudonha kwemafuta kuburikidza nedipstick. Kana iwe ukatanga mota uye ukatarisa mwero wemafuta, dipstick yese inogona kuvharwa negirizi. Pakumhanya kukuru (5-6 zviuru rpm), kupfira kubva kuprobe kunogoneka.

Panguva imwecheteyo, mota inomhanya zvakajairika uye haina kupisa, zvisinei, iyo lubrication level inodonha, iyo mune ramangwana yakazara nemafuta nzara. Zvinotendwa kuti chikonzero chinogona kunge chiri magasi mu crankcase, iyo inopinda ipapo kuburikidza nemasilinda. Izvi zvinoreva kuti kana masilinda akasakara, kana zvindori. Dambudziko rakafanana hariitiki kazhinji, asi rinoitika pane injini yeVQ30 (uye kugadziriswa kwayo) ine mileage yakasimba.

Kumwe kusasimba kweinjini idzi:

1. Kutyora kwechikamu chekugovera gasi.
2. Detonation, iyo inowanzoperekedzwa nekuwedzera kushandiswa kwemafuta. Kugadzirisa dambudziko iri, kuchenesa mavharuvhu kubva kune soot kunodiwa.
3. Yakashata MAF sensors (mass air metres), izvo zvinoita kuti injini ipedze huwandu hwemhepo - izvi zvinogadzira musanganiswa wakaonda.
4. Kurasikirwa kwekumanikidzwa muhuni system. Chero ipi zvayo yezvinhu zvayo inogona kuva isingashandisike - jekiseni pombi, mafirita, kudzvinyirira regulator.
5. Kusashanda majekiseni.
6. Kukundikana kwezvinokonzeresa, izvo zvinosanganisira kurasikirwa kwesimba.

Kazhinji, varidzi vemotokari dzine injini idzi vanobata chiteshi chesevhisi nechichemo pamusoro pechiedza cheCheck Engine chiri kubatidzwa. Kufamba kwechigarire kana kwekanguva hakuna kubviswa (apo imwe yemasilinda isingashande zvakanaka kana isingashande zvachose), iyo inoperekedzwa nekurasikirwa kwesimba.

Kazhinji izvi zvinosanganiswa nedambudziko mune yekupisa system. Kana "huropi" huchiongorora kushanda kwemakoiri uye kuona chero kusashanda, saka vanozivisa mutyairi nezveizvi vachishandisa mwenje weCheck Engine.

Muchiitiko ichi, kukanganisa P1320 kunoverengwa. Nehurombo, iwe unofanirwa kuona nemaoko kuti ndeipi coil isiri kushanda, inova chikanganiso cheiyo injini yekuongorora system.

Injini dzine Neo tekinoroji dzinoshandisa mavharuvhu eEGR, ayo anoderedza huwandu hwenitrogen oxides mumagasi ekupedza. Ichi chishandiso hachina simba uye chinoda pamhando yepamusoro yepeturu. Paunenge uchishandisa yakaderera-mhando mafuta (munyika yedu, mhando yepeturu yakaderera kana ichienzaniswa nemafuta muEurope), vharuvhu inogona kuvharwa ne soot uye wedge. Mumamiriro ezvinhu aya, haashande, saka mafuta-air musanganiswa anopiwa kune macylinders ane maitiro asina kunaka. Izvi zvinosanganisira kuderera kwesimba, kuwedzera gasi mileage uye nekukurumidza kupfeka injini. Panguva imwecheteyo, Cheki injini mwenje pane dashboard inovhenekera. Ziva kuti EGR vharafu idambudziko kune akawanda injini kwaanoshandiswa, uye kwete zvakananga kune VQ30DE akatevedzana injini.

mhedziso

Injini iyi inounganidza maitiro akanaka pakati pevaridzi vemotokari - haina kuzvikudza mukugadzirisa, yakavimbika, uye inonyanya kukosha - yakasimba. Unogona kuzvisimbisa iwe pachako nekutarisa masaiti ekutengesa mota dzakamboshandiswa. Kune Nissan Cedric uye Cima modhi ye1994-1995 pamusika ane anopfuura 250-300 zviuru zvemakiromita pane odometer. Muchiitiko ichi, iwe unogona kuwedzera kune data pamudziyo, sezvo vatengesi vanowanzoshandura "yepamutemo" mileage.
