Nissan QG18DD injini

Zamkatimu

Zolemba zamakono
Kudalirika kwagalimoto
Kusungika
Ndi mafuta amtundu wanji oti utsanulire
Magalimoto omwe injiniyi idayikidwapo

Nissan Motors ndi mtundu wamakono wa injini yomwe imakhala ndi njira zosavuta zotchulira injini iliyonse.

Awa ndi mayina a injini imodzi, komanso decoding ya mtundu wake:

mndandanda wamagulu;
kuchuluka;
jekeseni njira.
mbali zina za injini.

QG ndi banja la ma ICE a silinda anayi opangidwa ndi Nissan. Mzere wazogulitsa umaphatikizapo osati mitundu ya injini zanthawi zonse za DOHC, komanso mitundu yosiyanasiyana yazinthu zokhala ndi jakisoni wachindunji (DEO Di). Palinso mainjini omwe amayendetsa gasi wa liquefied QG18DEN. Ma motors onse a QG amadziwika ndi kukhalapo kwa makina omwe amakulolani kusintha magawo agasi, zomwe zimapangitsa kuti muzitha kuwona injini ngati analogue ya VVTi.

Qg18dd imadziwika kuti imapangidwa ku Japan ndi Mexico. Injini imakonzedwa kuti ikwaniritse torque pa RPM yotsika komanso mphamvu zambiri. Izi ndi zofunika kuonetsetsa kuti injini imayankha pedal. Chitsulo choponyedwa chimasankhidwa ngati chinthu chopangira injini, mutu wa silinda umapangidwa ndi aluminiyumu. Komanso, zambiri zimakhudza kwambiri magwiridwe antchito a mota:

jekeseni wamafuta a MPI;
zitsulo zopangira zitsulo;
camshafts opukutidwa;
kuchulukitsa kwa aluminiyumu.

QG18DE ili ndi ukadaulo wa N-VCT wopangidwa ndi Nissan ndipo idapereka Mphotho yaukadaulo ya 2001 RJC Technology.

Mndandanda wa injini za Nissan QG ndi zitsanzo zama injini zamafuta oyatsira mkati kuchokera kwa opanga Nissan Motors. Mndandandawu umayimiridwa ndi ma cylinder anayi ndi ma sitiroko anayi, kuchuluka kwake komwe kungakhale kofanana ndi:

1,3 L;
1,5 L;
1,6 L;
1,8 l.

Kukhalapo kwa njira yosinthira gawo ndikofanana ndi malo ogawa gasi m'dera la shaft. Ma injini ena amtunduwu amakhala ndi jekeseni wolunjika.

Injini ya 1,8-lita ili ndi Nissan Variable Cam Timing, yokonzedwa kuti ikhale yoyendetsa bwino mumzinda. The disassembled chithunzi akhoza kuonedwa pansipa. Nissan QG18DD injini

Kudalirika kwagalimoto

Kuti mudziwe kudalirika kwa injini, ndikofunika kudziwa za mbali zake zabwino ndi zoipa.

Ubwino wagawo:

Pali ma jekeseni - ma jekeseni ambiri. Anali mayunitsi amagetsi a QG omwe anali m'gulu loyamba kugwiritsa ntchito makinawa. Izi zisanachitike, idagwiritsidwa ntchito kokha pamagalimoto okhala ndi injini ya dizilo.
Kuonetsetsa kuyaka kwathunthu kwa mafuta, gawo la valve yapadera muzochuluka ndi mafuta oyendetsa mafuta amagwiritsidwa ntchito. Imagawanso kayendedwe ka mpweya malinga ndi katundu ndi liwiro, komanso zomwe zingatheke kupanga vortex ya chipinda choyaka moto.
The control cholumikizira maf masensa amalola kuwunika ndondomeko kuyaka mafuta. Chifukwa cha malo otsekedwa a valve yolamulira, pamene injini ikuwotha ndikuthamanga pamtunda wochepa, kuwonjezereka kowonjezereka kwa kayendedwe ka mafuta kumatheka. Izi bwino kuyaka makhalidwe a mafuta mu yamphamvu ndi amachepetsa mlingo wa asafe ndi carbon oxides.
Kuyang'ana linanena bungwe zizindikiro za injectors ikuchitika popanda mavuto;
Chothandizira chopepuka chimakhala ndi 50% yokulirapo yogwirira ntchito chifukwa cha kapangidwe katsopano ka mutu wa pistoni, komwe kumapereka mwayi wowongolera gawo lachilengedwe la mota.
Interchangeability coupling vvt i 91091 0122 pokonza ntchito.
Kwa injini, kutsata kwathunthu kwa miyezo yolimba ya chilengedwe E4 ku Germany ndi miyezo ya chilengedwe yomwe idayamba kugwira ntchito mu 2005 kumayiko aku Europe ndizotsimikizika.
Injini ya Nissan ili ndi mtundu wa Niss QG18DE womwe uli ndi dongosolo lomwe limalola kuwunika kwathunthu. Mulimonsemo, ngakhale kulephera kochepa kwambiri kwa zigawo za dongosolo lotayirira, izi zidzalembedwa panthawi yowunikira pa bolodi ndikulemba kukumbukira dongosolo.

Kuipa kwa chitsanzo ndizovuta kukonza, ndi katswiri yekha yemwe ali ndi chidziwitso chochuluka pakukonzekera ma motors angakhoze kuchita izi. Komanso, nthawi zina madalaivala amaona kuti injini si kuyamba nyengo yozizira.
