Txhua lub tsheb muaj nws tus kheej lub cav lub suab. Txawm hais tias tib tus qauv nrog tib lub mileage suab txawv. Thiab lub ntsiab lus tsis yog txawm nyob rau hauv cov yeeb nkab tso zis thiab tsis nyob rau hauv lub load, tab sis nyob rau hauv lub chav tsev nws tus kheej. Qhov sib txawv tseem ceeb yog lub cav ceev. Qhov tshaj plaws yog tias txhua chav fais fab muaj nws tus kheej hnav, uas dictates nws cov yam ntxwv, ob qho tib si tsav tsheb thiab idle.

RPM ntawm lub cav tuaj yeem qhia ntau txog nws tus mob. Lawv yuav tsum tau saib xyuas ob qho tib si ntawm qhov tsis ua haujlwm thiab thaum lub sijhawm nruab nrab thiab siab loads, vim qhov no yog tib txoj hauv kev los txiav txim siab seb "kev noj qab haus huv" lub hwj chim yog li cas. Yog tias lub cav tsis tuaj yeem ua haujlwm tag nrho, muaj ntau qhov laj thawj rau qhov no: sib txawv compression hauv lub tog raj kheej, kev hloov kho carburetor tawg, lossis lub sijhawm sib tsoo tsis raug. Yog hais tias, tom qab kuaj xyuas thiab normalizing tag nrho cov tsis tau, kev ua hauj lwm tsis tau rov qab los, ces nws yog tsim nyog xav txog cov teeb meem sab hauv, uas, feem ntau yuav, nqes los hnav ntawm lub piston rings los yog lub tog raj kheej. Tsis tas li ntawd, nws yuav nrog cov pa taws ntau ntxiv.

siabTsis siv neeg ceev ntawm lub cav kuj tseem tuaj yeem raug txiav txim los ntawm kev hloov kho tsis raug ntawm lub carburetor, tab sis rau cov kev txhaj tshuaj xws li kev ua haujlwm tsis raug suav nrog, qhov no tuaj yeem ua haujlwm tsis zoo ntawm chav tswj. Yog tias, txawm li cas los xij, cov roj siv hluav taws xob yog carbureted, ces lub cav tsis siv neeg ceev tau teeb tsa siv qhov tsis siv neeg kho cov ntsia hlau lossis ob lub ntsia hlau uas tswj cov nqi sib xyaw rau hauv lub tog raj kheej, nrog rau nws cov muaj pes tsawg leeg. Cov ntsia hlau no hu ua "quantity" thiab "zoo".

Dhau li ntawm qhov no, kuj tseem muaj hluav taws kub. Txawm hais tias nws yog kev sib cuag los yog tsis yog, lub sij hawm ignition tsis ncaj ncees lawm ua rau tsis yog tsuas yog nce hnav ntawm lub crank mechanism, tab sis kuj yuav ua rau muaj suab nrov vim kev kub ceev. Lawv tuaj yeem txo tau.

Lub cav nrawm tuaj yeem txo qis los ntawm kev hloov qhov hluav taws xob ua ntej lossis tom qab. Qhov no yog ua tiav nrog lub cav sov thiab lub carburetor kho kom raug. Nws tseem tsim nyog nco ntsoov qhov siab voltage nyob rau hauv lub ignition distributor. Qhov no yog ua los ntawm rotating nws lub cev nyob rau hauv cov kev taw qhia ntawm kev sib hloov ntawm slider - tom qab, los yog nyob rau hauv tsis tooj, ces ua ntej.

Ntxiv rau, koj yuav tsum xyuam xim rau lub cav ceev hauv qab kev hloov pauv. Yog hais tias chav tsev muaj peev xwm kov lub tsheb ntawm 1000-1200 rpm, qhov no qhia tau hais tias nws "flexibility", vim nws yog nyob rau lub sij hawm no uas tag nrho cov torque yog siv. Yog tias qhov siab tshaj plaws torque hloov mus rau sab siab dua ntawm kev hloov pauv - mus rau 1500, qhov no twb qhia qee qhov hnav ntawm cov pas nrig txuas thiab pawg piston.

Yog qhov nruab nrab ceev thaum tsav tsheb yog 2000-3000, tab sis qhov ceev yog qis, qhov no qhia tau tias tib yam. Tab sis qhov no, qhov teeb meem yuav tsis nyob hauv chav tsev nws tus kheej. Qhov no tuaj yeem yog qhov tshwm sim ntawm clutch slippage. Tej zaum yuav muaj ntau yam teeb meem thiab kev ua haujlwm tsis zoo, kev tshem tawm uas muaj nws tus kheej tshwj xeeb.

Yog li, koj yuav tsum nco ntsoov tias lub cav ceev yog qhov qhia tau tseem ceeb uas koj yuav tsum tau saib xyuas tas li thiab nrhiav qhov laj thawj rau lawv qhov kev hloov pauv.
