Txheej txheem cej luam ntawm Nissan HR12DE thiab HR12DDR cav
Lub ICE (internal combustion engine) Nissan HR12DE tau tso tawm nyob rau hauv 2010 los ntawm lub zoo-paub tuam txhab Nissan Motors. Los ntawm hom cav, nws txawv raws li hauv-kab thiab muaj 3 lub tog raj kheej thiab 12 li qub. Lub ntim ntawm lub cav no yog 1,2 litres. Nyob rau hauv lub piston system, lub piston txoj kab uas hla yog 78 millimeters thiab nws stroke yog 83,6 millimeters. Cov roj txhaj tshuaj yog nruab Ob Lub Taub Hau Camshaft (DOHC).
Xws li ib tug system predetermines lub installation ntawm ob camshafts nyob rau hauv lub tog raj kheej taub hau (lub tog raj kheej taub hau). Cov cuab yeej tsim hluav taws xob zoo li no ua rau nws ua tau kom ua tiav lub suab nrov txo qis thiab tau txais lub zog ntawm 79 horsepower, nrog rau lub zog ntawm 108 Nm. Lub cav muaj qhov hnyav hnyav: 60 kilograms (dawb lub cav hnyav).

Lub cav no tau dhau los ua lub zog loj heev, nyob rau hauv lub tshuab xa tawm roj, tsis yog siv txoj siv, cov chaw tsim khoom tau teeb tsa cov saw hlau ntxiv rau kev hnav tsis kam thiab nws yuav luag tsis tuaj yeem ua rau ntxov ntxov ncab ntawm nws. Lub sij hawm system muaj ib theem hloov system. Ib qho hluav taws xob tswj lub tshuab hluav taws xob kuj tau nruab. Tab sis ib qho ntawm cov teeb meem tsis zoo yog tias txhua txhua 70-90 txhiab kilometers, nws yuav tsum tau kho lub valve clearances, vim hais tias lub system tsis muab rau lub installation ntawm hydraulic lifters. Cov txheej txheem no tsis siv sijhawm ntau, tab sis nws tsis pheej yig heev.
Nyob
Raws li txoj cai, lub zog ntawm lub cav tsis tu ncua yuav tsis txaus, yog li nws tuaj yeem txhim kho nws qhov kev ua tau zoo los ntawm kev siv hluav taws xob lossis kev kho tshuab.
Nrog rau kev hloov hluav taws xob, qhov hu ua chipping yog ua, tab sis koj yuav tsum tsis txhob cia siab tias yuav muaj zog ntxiv, txog + 5% rau lub cav fais fab.
Nrog mechanical tuning, ntsig txog, muaj ntau lub sijhawm. Txhawm rau kom muaj lub zog zoo, koj tuaj yeem tso lub cav, hloov lub tso pa tawm, tso rau pem hauv ntej ntws thiab cua txias, yog li koj tuaj yeem nce ntawm 79 horsepower mus rau 125-130.
Cov kev txhim kho zoo li no yog qhov kev nyab xeeb tshaj plaws, kev hloov kho lub cav ntxiv, piv txwv li: lub tog raj kheej tho txawv, tuaj yeem ua rau poob ntawm tus qauv lub zog thiab cov khoom siv lub neej.
Kev kho mob
Txhawm rau kom lub cav ua haujlwm tau ntev thiab tsis poob, kev saib xyuas tsis tu ncua yuav tsum tau nqa tawm, cov khoom siv yuav tsum tau hloov raws sijhawm, siv cov roj pom zoo los ntawm cov chaw tsim khoom rau cov qauv ntawm lub cav no, thiab tseem hloov tau raws sijhawm.
Nissan HR12DDR cav kuj tau tso tawm nyob rau hauv 2010, feem ntau nws yog ib tug modernized HR 12 DE. Kev ua haujlwm ntim tsis tau hloov pauv, tsuas yog 1,2 litres xwb. Ntawm kev ua kom zoo dua qub, nws yuav tsum tau muab sau tseg tias kev teeb tsa ntawm lub turbocharger, kev siv roj kuj tseem txo, thiab lub siab dhau ntawm lub tog raj kheej raug tshem tawm. Cov kev hloov kho no ua rau nws muaj peev xwm nce lub zog rau 98 horsepower thiab tau txais lub zog ntawm 142 Nm. Lub ntsiab tsis tau hloov.

Lub cav no tau txhim kho tau zoo thaum lub sijhawm tsim khoom thiab tsis muaj kev sib tsoo uas tshwm sim tsis muaj laj thawj.
Nyob
Xws li lub cav qauv kuj tuaj yeem ua kom muaj zog dua los ntawm kev siv hluav taws xob thiab kev kho tshuab, uas tau piav qhia saum toj no. Tab sis nws tsim nyog nco ntsoov cov kev txwv ntawm kev nkag mus rau qhov kev hloov kho tshiab. Nyob rau hauv cov ntaub ntawv ntawm radical hloov, tsis ua hauj lwm ntawm tag nrho cov system yog ua tau.
Kev kho mob
Txhawm rau kom tsis txhob muaj teeb meem nrog cov qauv ntawm lub cav no, nws yog ib qho tsim nyog yuav tsum tau saib xyuas tag nrho raws sijhawm, hloov cov roj thiab cov khoom siv raws sijhawm, thiab siv cov roj zoo.
