Cav 1HZ
Japanese cav tsim nyog tau txais kev hwm thoob plaws ntiaj teb. Tshwj xeeb tshaj yog thaum nws los txog rau diesel units nrog lub npe HZ. Thawj lub zog ntawm cov kab no yog lub cav 1HZ - lub tshuab hluav taws xob muaj zog uas tau los ua cov lus dab neeg nyob rau hauv thaum ntxov 90s.
Keeb kwm thiab cov yam ntxwv ntawm lub cav
Lub zog 1HZ tau tsim nyob rau thaum ntxov 90s ntawm lub xyoo pua xeem tshwj xeeb rau tiam tshiab ntawm Land Cruiser 80 series SUVs. Lub tsheb nrog lub tsev no tau muab rau yuav luag txhua lub tebchaws hauv ntiaj teb, vim tias kev tsim qauv tsim qauv ntawm Toyota 1HZ ua rau nws muaj peev xwm ua haujlwm tau lub cav no hauv txhua qhov xwm txheej.
Specifications tau ncaj ncees nruab nrab:
| Cov ntim ua haujlwm | 4.2 liters |
| Roj | diesel cav |
| Rated zog | 129 horsepower ntawm 3800 rpm |
| Torque | 285 Nm ntawm 2200 rpm |
| Real mileage peev xwm (peev txheej) | 1km ua |
Thaum pib ntawm kev tsim khoom, 1HZ diesel tsis tau tshaj tawm los ntawm lub tuam txhab ua ib lub zog muaj zog. Tab sis twb nyob rau hauv nruab nrab-90s, nws tau pom tseeb tias ib lab mais deb ntawm qhov txwv ntawm kev siv cov txuj ci tseem ceeb ntawm Japanese engineering.
Hauv peb lub tebchaws, koj tseem tuaj yeem ntsib thawj SUVs nruab nrog 1HZ sab hauv combustion xyaw. Cov tsheb no tau rov pib dua tus nqi mais thiab txog rau hnub no tsis yog cov neeg siv khoom siv tsheb ntau heev.
Qhov zoo tshaj plaws
Lub zog tseem ceeb ntawm lub cav tsis yog cov yam ntxwv. Nrog xws li ib tug loj ntim, chav tsev tsis tsim ntau li ntawd nees. Tej zaum, qhov tsis txaus no yuav raug kho los ntawm lub turbine, tab sis nrog nws lub peev xwm ntawm chav tsev yuav raug txo kom tsawg.
Tom qab ua tiav cov kev tshuaj xyuas ntawm cov tsav tsheb nrog 1HZ chav tsev, qhov zoo hauv qab no ntawm lub tshuab hluav taws xob ntawm Toyota tuaj yeem paub qhov txawv:
- loj mileage peev xwm;
- tsis muaj kev puas tsuaj me
- kev ua tiav ntawm cov roj diesel kiag li;
- kam rau ua rau huab cua kub ntawm kev ua haujlwm;
- txhim khu kev qha piston pab pawg neeg yuav tsum overhaul thiab tho txawv.
Ntawm chav kawm, qhov kev cia siab thiab kev cia siab ntawm chav tsev nyob ntawm cov xwm txheej thiab cov yam ntxwv ntawm nws txoj haujlwm. Yog tias koj hloov cov roj hauv lub sijhawm, kho lub valve clearances thiab ignition, teeb meem nrog kev ua haujlwm ntawm lub tsheb yuav tsis tshwm sim.
Muaj teeb meem cav
Yog tias qhov kev hloov kho lub valve tsis tau ua tiav raws sijhawm, tab sis nrog kev ncua ntev, kev hnav piston tuaj yeem tshwm sim. Tsis tas li ntawd, qhov kev daws teeb meem ntawm pawg piston tau pom thaum siv ntau yam esters kom sai sai pib lub cav combustion hauv huab cua txias.
Tsis txhob hnov qab tias nyob rau hauv pem hauv ntej ntawm koj yog ib tug ncaj ncees qub zog chav tsev. Koj yuav tsum ceev faj ntxiv nrog nws. Lwm yam teeb meem kho kho muaj xws li:
- kev txhaj tshuaj twj tso kua mis raug kev txom nyem ntawm yuav luag tag nrho cov cav nyob ze rau 500 txhiab mais;
- chav tsev yuav tsum tau muab kev pab tsuas yog los ntawm ib tug kws tshwj xeeb - ib tug tshwj xeeb installation ntawm 1HZ ignition marks yog yuav tsum tau ntawm no;
- tsis zoo roj maj mam rhuav tshem cov piston pawg thiab li qub.
Tej zaum tsis muaj qhov tsis txaus nyob hauv lub cav no. Ib qho ntawm qhov zoo ntawm kev muaj lub tsheb nrog lub zog zoo li no yog tias koj tuaj yeem yuav daim ntawv cog lus 1HZ lub cav thaum cov neeg nyob hauv ib cheeb tsam tau mus txog ntau tshaj li ib lab kilometers. Niaj hnub no, cov txheej txheem zoo li no yuav tsis raug nqi ntau dhau rau koj, tab sis yuav muab lub tsheb nrog lub cav yuav luag tshiab.
Summing txog
Lub cheeb tsam ntawm kev siv lub cav 1HZ yog Land Cruiser 80, Land Cruiser 100 thiab Toyota Coaster Bus. Txog rau tam sim no, cov tsheb nrog cov fais fab no tseem siv tau thiab tsis txhob cia lawv cov tswv poob.
Nws yog ib qho ntawm cov cav zoo tshaj plaws ntawm Toyota Corporation, uas tau koom nrog hauv kev tsim lub tuam txhab lub npe. Nws yog ua tsaug rau xws li inventions uas lub tuam txhab muaj kev hwm thoob plaws ntiaj teb niaj hnub no.
