Momwe mungasinthire nthawi pagalimoto

Nthawi yoyatsira imatanthawuza njira yoyatsira yomwe imalola kuti spark plug kuyatsa kapena kuyatsa madigiri pang'ono pisitoni isanafike pakatikati pakufa (TDC) pa chipwirikiti. Mwa kuyankhula kwina, nthawi yoyatsira ndikusintha kwa spark opangidwa ndi spark plugs mu dongosolo loyatsira.

Pamene pisitoni ikupita pamwamba pa chipinda choyaka moto, ma valve amatseka ndi kulola injini kukakamiza kusakaniza kwa mpweya ndi mafuta mkati mwa chipinda choyaka moto. Ntchito ya poyatsira moto ndi kuyatsa mpweya / mafuta osakanizawa kuti apange kuphulika kolamulirika komwe kumapangitsa injini kuyendayenda ndikupanga mphamvu zomwe zingagwiritsidwe ntchito kuyendetsa galimoto yanu. Nthawi yoyatsira kapena spark imayesedwa ndi madigiri momwe crankshaft imazungulira kubweretsa pisitoni pamwamba pa chipinda choyaka moto, kapena TDC.

Ngati pisitoni ifika pamwamba pa chipinda choyaka moto, chomwe chimatchedwanso kuti nthawi, kuphulika kolamulirikako kumagwira ntchito motsutsana ndi kuzungulira kwa injiniyo ndikutulutsa mphamvu zochepa. Ngati phokoso limachitika pisitoni itayamba kubwereranso mu silinda, yomwe imatchedwa kuti timing lag, kupanikizika komwe kumapangidwa ndi kuphatikizika kwamafuta a mpweya kumatayika ndikupangitsa kuphulika pang'ono, kulepheretsa injini kukhala ndi mphamvu zambiri.

Chizindikiro chabwino chosonyeza kuti nthawi yoyatsira ingafunikire kusinthidwa ndi ngati injini ikuyenda mowonda kwambiri (mpweya wambiri, mafuta osakwanira mu mafuta osakaniza) kapena olemera kwambiri (mafuta ochulukirapo komanso mpweya wokwanira mu mafuta osakaniza). Izi nthawi zina zimawoneka ngati kuthamangitsa injini kapena ping pothamanga.

Nthawi yoyenera kuyatsa idzalola injini kupanga mphamvu zambiri bwino. Kuchuluka kwa madigiri kumasiyanasiyana ndi wopanga, choncho ndi bwino kuyang'ana buku la ntchito ya galimoto yanu kuti mudziwe ndendende mlingo woyenera kukhazikitsa nthawi yoyatsira.

Gawo 1 la 3: Kuzindikira masitampu anthawi

Zida zofunika

• wrench ya kukula koyenera
• Kukonza Kwaulere Manuals Autozone imapereka zolemba zaulere zapaintaneti zamtundu wa Autozone.
• Kukonza zolemba (posankha) Chilton

Magalimoto akale okhala ndi makina opangira magetsi amatha kuwongolera nthawi yoyatsira. Monga lamulo, nthawi imayenera kusinthidwa chifukwa cha kuvala kwanthawi zonse ndi kung'ambika kwa magawo osuntha mu dongosolo loyatsira. Digiri imodzi imatha kuwoneka ngati ikugwira ntchito, koma pa liwiro lalikulu imatha kupangitsa kuti makina oyatsira moto aziyaka posachedwa, ndikuchepetsa magwiridwe antchito a injini.

Ngati galimoto yanu imagwiritsa ntchito makina oyatsira osagawa, monga coil-on-plug, nthawi yake siingathe kusinthidwa chifukwa kompyuta imapanga kusintha kumeneku pa ntchentche pakufunika.

Gawo 1 Pezani crankshaft pulley.. Injini itazimitsa, tsegulani hood ndikupeza pulley ya crankshaft.

Padzakhala chizindikiro pa pulley ya crankshaft pamodzi ndi chizindikiro cha digiri pachivundikiro cha nthawi.

• Ntchito: Zizindikiro izi zitha kuwonedwa ndi injini ikuyenda powunikira malowa ndi nyali yanthawi yake kuti muwone ndikusintha nthawi yoyatsira.

Gawo 2: Pezani silinda nambala wani. Nthawi zambiri zizindikiro zimakhala ndi zokopa zitatu.

Zingwe zotsekera zabwino/zofiyira ndi zoipa/zakuda zimalumikizana ndi batire yagalimoto, ndipo cholumikizira chachitatu, chomwe chimadziwikanso kuti inductive clamp, chimamangitsa waya wa spark plug wa silinda nambala wani.

• NtchitoA: Ngati simukudziwa kuti silinda nambala #1, onani zambiri zokonza fakitale kuti mudziwe zambiri za dongosolo loyatsira.

Khwerero 3: Masuleni mtedza wosintha pa wogawa.. Ngati nthawi yoyatsira ikufunika kusinthidwa, masulani mtedzawu mokwanira kuti wogawayo azizungulira kuti apite patsogolo kapena kuchedwetsa nthawi yoyatsa.

Gawo 2 la 3: Kuzindikira Kufunika Kwa Kusintha

Zida zofunika

• wrench ya kukula koyenera
• Kukonza Kwaulere Manuals Autozone imapereka zolemba zaulere zapaintaneti zamtundu wa Autozone.
• Kukonza zolemba (posankha) Chilton
• Kuwala chizindikiro

Gawo 1: Yatsani injini. Yambitsani injini ndikuilola kuti itenthe mpaka kutentha kwa madigiri 195.

Izi zikuwonetsedwa ndi kuwerengera kwa muvi wa kutentha kwapakati pa geji.

Gawo 2: Gwirizanitsani chizindikiro cha nthawi. Ino ndi nthawi yolumikiza kuunika kwanthawi ku batri ndi pulagi yoyamba ya spark ndikuwunikira kuwala kwanthawi pa crankshaft pulley.

Yerekezerani zowerengera zanu ndi zomwe wopanga akupanga mu bukhu lokonza fakitale. Ngati nthawi yasokonekera, muyenera kuyisintha kuti injiniyo isagwire bwino ntchito.

• Ntchito: Ngati galimoto yanu ili ndi zida zoyatsira vacuum, chotsani chingwe cha vacuum chopita kwa wogawa ndikulumikiza chingwecho ndi bawuti yaying'ono kuti mupewe kutayikira kwa vacuum panthawi yoyatsa.

Gawo 3 la 3: Kupanga zosintha

Zida zofunika

• wrench ya kukula koyenera
• Kukonza Kwaulere Manuals Autozone imapereka zolemba zaulere zapaintaneti zamtundu wa Autozone.
• Kukonza zolemba (posankha) Chilton
• Kuwala chizindikiro

Khwerero 1: Masulani mtedza wosintha kapena bawuti. Bwererani ku nati yosintha kapena bolt pa wogawa ndikumasula mokwanira kuti wogawayo azizungulira.

• NtchitoYankho: Magalimoto ena amafunikira chodumphira pa cholumikizira magetsi kuti chifupikitse kapena kuleka kulumikizana ndi kompyuta yagalimotoyo kuti nthawi yake isinthe. Ngati galimoto yanu ili ndi kompyuta, kulephera kutsatira njira imeneyi kudzalepheretsa kompyutayo kuvomereza zoikamo.

Khwerero 2: Sinthani wogawa. Pogwiritsa ntchito chizindikiro cha nthawi kuti muyang'ane zizindikiro za nthawi pachivundikiro cha crank ndi nthawi, tembenuzirani wogawayo kuti asinthe zofunikira.

• Chenjerani: Galimoto iliyonse ikhoza kukhala yosiyana, koma lamulo lalikulu ndiloti ngati rotor mkati mwa wogawayo imayenda mozungulira pamene injini ikugwira ntchito, kusinthasintha kwa wogawayo kumasintha nthawi yoyatsira. Kutembenuza wogawayo molunjika kudzakhala ndi zotsatira zosiyana ndikuchedwetsa nthawi yoyatsira. Ndi dzanja lolimba la magulovu, tembenuzirani wogawa pang'ono mbali iliyonse mpaka nthawi ili mkati mwa zomwe wopanga afuna.

Khwerero 3: Limbani mtedza wosintha. Pambuyo poyika nthawiyo mopanda ntchito, limbitsani mtedza wosintha pa wogawa.

Funsani bwenzi lanu kuti aponde pa pedali. Izi zimaphatikizapo kufooketsa mwachangu chowongolera chowongolera kuti chiwonjezeke liwiro la injini ndikuchimasula, kulola kuti injini ibwerere osagwira ntchito, potero kutsimikizira kuti nthawiyo yakhazikitsidwa molingana ndi zofunikira.

Zabwino zonse! Mwangokhazikitsa nthawi yanu yoyatsira. Nthawi zina, nthawi yoyatsira sikhala yodziwika chifukwa cha unyolo wotambasulidwa kapena lamba wanthawi. Ngati, mutatha kukhazikitsa nthawi, galimotoyo ikuwonetsa zizindikiro za kusalunzanitsa, tikulimbikitsidwa kuti mulumikizane ndi makaniko ovomerezeka, mwachitsanzo, ochokera ku AvtoTachki, kuti mudziwe zambiri. Akatswiriwa amatha kukuyikirani nthawi yoyatsira ndikuwonetsetsa kuti ma spark plugs anu ali apo.
