Nws yog qee zaum sau tseg ntawm cov rooj sib tham uas banal wrapping ntawm cov xov hlau nrog insulating daim kab xev tuaj yeem daws qhov teeb meem nrog qhov yuam kev. Tab sis rau qhov no nws yog ntshaw kom siv cov hluav taws kub-resistant daim kab xev thiab insulate nyob rau hauv ob peb txheej.
Qee tus tswv tsheb nco ntsoov tias ib lossis ntau qhov ua yuam kev saum toj no tuaj yeem tshwm sim yog tias koj sau lub tsheb nrog cov roj av tsis zoo nrog qhov ntsuas octane qis dua li tau hais los ntawm lub tshuab hluav taws xob sab hauv. Yog li ntawd, yog tias tom qab kuaj xyuas koj tsis pom muaj kev ua haujlwm tsis zoo, tsuas yog sim hloov qhov chaw nres tsheb roj. Rau qee tus neeg nyiam tsheb, qhov no tau pab.
Muaj tsawg zaus, koj tuaj yeem ua yam tsis tau hloov lub khob khob. Hloov chaw, koj tuaj yeem sim rov ua nws qhov kev ua tau zoo. uas yog, nrog kev pab ntawm cov ntawv xuab zeb thiab / lossis cov ntaub ntawv, nws yog ib qho tsim nyog los ntxuav nws cov hlau nto kom tshem tawm cov av thiab xeb ntawm nws (yog tias lawv nyob ntawd). Yog li koj tuaj yeem nce (rov qab) cov neeg kho tshuab kev sib cuag ntawm lub sensor thiab lub tog raj kheej thaiv.
kuj yog ib qho nthuav kev soj ntsuam yog tias lub khob sensor tuaj yeem ua yuam kev cov suab nrov rau detonation. Ib qho piv txwv yog lub zog tiv thaiv ICE tsis muaj zog, vim tias qhov kev tiv thaiv nws tus kheej rattles ntawm txoj kev, thiab lub sensor tuaj yeem ua haujlwm tsis raug, xa cov teeb liab mus rau lub computer, uas ua rau ignition lub kaum sab xis, thiab "knocking" txuas ntxiv. Hauv qhov no, qhov yuam kev tau piav qhia saum toj no tuaj yeem tshwm sim.
Hauv qee cov qauv ntawm cov tshuab, cov kev ua yuam kev no yuav tshwm sim tshwm sim, thiab nws nyuaj rau rov ua dua. Tseeb, nyob rau hauv qee lub tsheb, lub khob sensor tsuas yog ua haujlwm ntawm qee txoj haujlwm ntawm crankshaft. Yog li ntawd, txawm tias thaum tapping rau ntawm lub cav combustion nrog rauj, nws tuaj yeem ua tsis tau rov tsim dua qhov yuam kev thiab nkag siab qhov laj thawj. Cov ntaub ntawv no yuav tsum tau qhia meej ntxiv thiab nws yog qhov zoo dua yog hu rau lub tsheb pabcuam kev pabcuam rau qhov no.
Qee lub tsheb niaj hnub no muaj txoj kev ntxhib los mos uas cuam tshuam lub khob qhov muag thaum lub tsheb tsav ntawm txoj kev ntxhib thiab lub crankshaft yog slamming thiab ua suab nrov zoo ib yam li roj detonation. Tias yog vim li cas kev kuaj xyuas lub khob sensor thaum lub tshuab hluav taws xob sab hauv khiav, thaum qee yam hnyav raug ntaus ntawm lub cav, tom qab ntawd lub cav ceev poob, tsis yog ib txwm raug. Yog li nws yog qhov zoo dua los kuaj xyuas tus nqi ntawm qhov hluav taws xob uas nws tsim thaum lub sij hawm cov neeg kho tshuab cuam tshuam rau lub cav combustion sab hauv.

Raws li tau hais los saum toj no, tag nrho plaub qhov yuam kev tau piav qhia tsis yog qhov tseem ceeb, thiab lub tsheb tuaj yeem tsav mus rau lub chaw nres tsheb lossis kev pabcuam tsheb ntawm nws tus kheej. Txawm li cas los xij, qhov no yuav ua rau muaj kev puas tsuaj rau lub tshuab hluav taws xob sab hauv yog tias lub tshuab hluav taws xob hauv lub tshuab hluav taws xob sab hauv combustion tshwm sim. Yog li ntawd, yog tias muaj qhov yuam kev no tshwm sim, nws tseem xav kom tshem tawm lawv sai li sai tau thiab tshem tawm cov laj thawj uas ua rau lawv. Txwv tsis pub, muaj kev pheej hmoo ntawm kev puas tsuaj, uas yuav ua rau mob hnyav, thiab tseem ceeb tshaj plaws, kho dua tshiab.
