Lub ntsiab tseem ceeb ntawm lub sij hawm saw yog xa lub zog los ntawm lub crankshaft los tsav lub valve mechanism ntawm lub tsheb cav los xyuas kom meej tias lub tog raj kheej piston ntawm lub tsheb cav muaj peev xwm ib txwm ua kom tiav plaub strokes ntawm noj, combustion, ua hauj lwm, thiab tso zis, thiaj li ua kom lub cev ua haujlwm ntawm lub cav tsheb. Ua hauj lwm, tag nrho cov system yog tsim los ntawm cov iav, chains thiab tensioning li. Ntawm lawv, hydraulic tensioner tuaj yeem hloov kho lub zog tensioning, kom cov saw nro zoo ib yam, tsis yog tsuas yog kev nyab xeeb thiab kev ntseeg tau raug txhim kho rau qee yam, tab sis kuj siv lub cav, tus nqi tu tau raug txo qis. ntau, uas tuaj yeem piav qhia tau ntau yam txiaj ntsig hauv ib qho kev poob qis.

Dab tsi yog cov tsos mob ntawm lub sij hawm elongated?

Feem ntau hais lus, lub sij hawm saw yuav tsis tawg, nws tsuas yog elongated. Yog hais tias cov saw yog elongated, yuav muaj qhov txawv txav, xws li lub teeb tsis raug, lub suab nrov txawv txav yog pom tseeb thaum idling, thiab cov saw yuav hla cov hniav tom qab elongated. Nws tseem yuav ua puas lub cav los ntawm topping lub valve. Vim hais tias ntawm lub tensioner, tom qab cov saw yog stretched, lub tensioner yuav tig mus rau sab nraud thiab txuas ntxiv kom nruj cov saw hlau. Thaum lub tensioner hloov mus rau qhov txwv, cov saw hlau tsis tuaj yeem hloov kho yog tias nws ncav cuag, thiab nws yuav tsum tau hloov lub sijhawm no.

Ntau npaum li cas kilometers yog qhov tsim nyog tshaj hloov?

Nws tuaj yeem hais tau tias kev pabcuam lub neej ntawm lub sijhawm siv sijhawm ntev heev. Qee lub tsheb tsis tas yuav tsum tau hloov thaum lawv muab pov tseg, thiab qee lub tsheb yuav tsum tau hloov yog tias lawv tsawg dua 100,000 mais. Txwv tsis pub, lub tsheb yuav siv tsis tau ib txwm. Lub neej kev pab cuam ntawm lub sij hawm saw feem ntau yog hais txog 150,000 rau 200,000 kilometers. Yog tias lub tsheb thauj khoom dhau sijhawm ntev ntawm kev kub ceev, nws yuav tsum tau kuaj xyuas 5 xyoos lossis 75,000 mais. Yog tias nws hnav hnyav heev lossis puas, nws yuav tsum tau hloov raws sijhawm. Yog tias koj tsav tsheb ntau maj mam thiab lub nra ntawm lub tsheb me me, lub neej kev pabcuam ntawm cov saw yuav ntev dua.

Feem ntau hais lus, kev ntseeg siab ntawm lub sijhawm sib txuas yog siab heev. Nws tseem nyob ntawm qhov chaw tsav tsheb thiab lwm yam tseem ceeb sab nraud. Nws raug tshuaj xyuas raws sijhawm raws li kev siv thiab ib puag ncig, thiab hloov thaum tsim nyog.
