Accord 7 Knock Sensor

Sensor kugogoda kwa injini ndi imodzi mwama sensor mu kasamalidwe ka injini. Ngakhale kudalirika wachibale wa kugogoda kachipangizo pa Honda Mogwirizana 7, nthawi zina amalephera. Ganizirani za chipangizocho ndi zifukwa za kusagwira ntchito kwa sensa, zotsatira zomwe zingatheke, njira zowongolera ndi ndondomeko yosinthira sensa.

Knock sensor chipangizo Accord 7

Magalimoto achisanu ndi chiwiri a Accord amagwiritsa ntchito sensa yamtundu wa resonant. Mosiyana ndi sensa ya Broadband yomwe imatumiza kuchuluka kwa kugwedezeka kwa injini kupita kugawo lowongolera, masensa a resonant amangoyankha kuthamanga kwa injini komwe kuli mkati mwa liwiro la crankshaft. Izi zili ndi ubwino ndi kuipa kwake.

Mfundo yabwino ndi yakuti injini yoyang'anira injini sayenera "kuyang'anira" machenjezo onyenga, mwachitsanzo, phokoso lapamwamba la lamba wa alternator, ndi kugwedezeka kwina kwachilendo. Komanso, masensa a resonant ali ndi matalikidwe apamwamba a chizindikiro chamagetsi, zomwe zikutanthauza chitetezo chokwanira cha phokoso.

Mphindi yoipa - sensa imakhala ndi chidwi chochepa pamunsi, ndipo, mosiyana, imathamanga kwambiri. Izi zingapangitse kuti chidziwitso chofunikira chiwonongeke.

Mawonekedwe a kugogoda sensor Accord 7 akuwonetsedwa pachithunzichi:

Kuwonekera kwa sensor yogogoda

Panthawi ya kuphulika kwa injini, kugwedezeka kumatumizidwa ku mbale yogwedezeka, yomwe, imatulutsa, imakulitsa kugwedezeka kwamakina mobwerezabwereza. Piezoelectric element imasintha kugwedezeka kwamakina kukhala kugwedezeka kwamagetsi komwe kumatsatira gawo lowongolera injini.

Kapangidwe ka sensor

Cholinga cha sensor yogogoda

Cholinga chachikulu cha injini kugogoda sensa ndi kukonza mbali yoyatsira injini pamene injini ikugogoda mphamvu ilipo. Kugogoda kwa injini nthawi zambiri kumagwirizanitsidwa ndi kuyamba koyambirira. Kuyamba kwa injini kumatheka pamene:

• kuwonjezera mafuta otsika (mwachitsanzo, ndi octane otsika);
• kuvala kwa njira yogawa gasi;
• kuyika kolakwika kwa ngodya yoyatsira panthawi yoteteza ndi kukonza.

Chizindikiro chogogoda chikazindikirika, gawo lowongolera injini limakonza momwe mafuta amaperekera, amachepetsa nthawi yoyatsira, mwachitsanzo, kuchedwetsa kuyatsa, kuletsa kuphulika. Ngati sensa sikugwira ntchito bwino, zotsatira za detonation sizingapewedwe. Izi zitha kubweretsa zovuta zazikulu, monga:

• kuwonjezeka kwakukulu kwa katundu pazigawo ndi machitidwe a injini;
• kusayenda bwino kwa dongosolo logawa gasi;
• zovuta kwambiri kufunikira kwa kukonzanso injini.

Kulephera kwa sensor yogogoda ndizotheka pazifukwa izi:

• kuvala;
• kuwonongeka kwamakina panthawi yokonza kapena pakachitika ngozi yapamsewu.

Njira zowunikira kusagwira ntchito kwa sensor yogogoda

Chizindikiro chachikulu cha sensa yogogoda yoyipa ndi kukhalapo kwa kugogoda kwa injini, komwe kumamveka pamene accelerator pedal ikanikizidwa mwamphamvu pansi pa katundu, monga poyendetsa kutsika kapena kuthamanga. Pankhaniyi, onetsetsani kuti muyang'ane ntchito ya sensa.

Njira yodalirika yodziwira kulephera kwa injini ya Accord 7 kugogoda kachipangizo ndikuyendetsa diagnostics pakompyuta. Khodi yolakwika P0325 imagwirizana ndi cholakwika cha sensor yogogoda. Mutha kugwiritsanso ntchito njira yowongolera parametric. Kuti muchite izi, sensor iyenera kuchotsedwa. M'pofunikanso kugwiritsa ntchito kwambiri tcheru AC voltmeter (mungagwiritse ntchito multimeter monga njira yomaliza, kuika lophimba ku malire otsika kuyeza AC voteji) kapena oscilloscope kuona mlingo chizindikiro pakati pa mlandu ndi sensa linanena bungwe. kupanga tokhala ting'onoting'ono pa chipangizo.

Kukula kwa ma siginecha kuyenera kukhala osachepera 0,5 volts. Ngati sensa ili bwino, muyenera kuyang'ana mawaya kuchokera kwa iyo kupita ku gawo lowongolera injini.

Ndizosatheka kuyang'ana sensa ndi toni yosavuta yoyimba ndi multimeter.

Kusintha sensor yogogoda ndi Accord 7

Sensor yogogoda ili pamalo osokonekera kuti ilowe m'malo: pansi pazakudya zambiri, kumanzere kwa choyambira. Mutha kuwona malo ake mwatsatanetsatane pachojambula chojambula.

Pachithunzichi, sensor ikuwonetsedwa pagawo 15.

Musanayambe kugwetsa sensa yogogoda, m'pofunika kuchiza malo opangira sensa ndi pepala lachitsulo kapena zina zapadera kuti muchotse coke, chifukwa panthawi ya ntchito inali yochuluka kwambiri kutentha.

Sensa yatsopano yogogoda ndiyotsika mtengo. Mwachitsanzo, kachipangizo koyambirira kopangidwa ku Japan pansi pa nkhani 30530-PNA-003 kumawononga pafupifupi ma ruble 1500.

Mukakhazikitsa sensa yatsopano, muyenera kukonzanso zolakwika za injini pogwiritsa ntchito scanner yowunikira.
