Inzwa ye-Accord 7 Knock

Inzwa yokushaya injini ingenye yezinzwa ohlelweni lokuphatha injini. Naphezu kokuthembeka okuhlobene kwenzwa yokungqongqoza ku-Honda Accord 7, ngezinye izikhathi ihluleka. Cabangela idivayisi kanye nezizathu zokungasebenzi kwenzwa, imiphumela engenzeka, izindlela zokulawula kanye nokulandelana kokushintsha inzwa.

I-Knock sensor device Accord 7

Izimoto zesizukulwane sesikhombisa ze-Accord zisebenzisa i-resonant type knock sensor. Ngokungafani nenzwa ye-broadband edlulisela yonke i-spectrum yokudlidliza kwenjini kuyunithi yokulawula, izinzwa ezinomsindo ozwakalayo zisabela kuphela kuzivinini zenjini ezingaphakathi kwejubane le-crankshaft. Lokhu kunezinzuzo kanye nokubi.

Iphuzu elihle ukuthi iyunithi yokulawula injini akufanele "ithamele" ama-alamu angamanga, isibonelo, ukuhayiza okuphezulu kwebhande le-alternator, nokunye ukudlidliza okungaphandle. Futhi, izinzwa ze-resonant zine-amplitude ephakeme yesiginali kagesi, okusho ukuthi izinga lomsindo eliphakeme.

Isikhathi esibi - inzwa inokuzwela okuphansi phansi, futhi, ngokuphambene, isivinini esiphezulu senjini. Lokhu kungase kuphumele ekulahlekelweni kolwazi olubalulekile.

Ukubonakala kwe-knock sensor Accord 7 kuboniswa esithombeni:

Ukubonakala kwenzwa yokungqongqoza

Ngesikhathi sokuqhunyiswa kwenjini, ukudlidliza kudluliselwa epuleti elidlidlizayo, okuthi, lizwakale, likhulise ngokuphindaphindiwe ukundindizela kwemishini. Isici se-piezoelectric siguqula ukudlidliza kwemishini kube ukudlidliza kukagesi okulandela iyunithi yokulawula injini.

Idizayini yenzwa

Inhloso yesenzwa sokungqongqoza

Inhloso enkulu yenzwa yokushayisa kwenjini ukulungisa i-engeli yokuthungela lapho injini ishaya khona. Ukushaya kwenjini kuvame ukuhlotshaniswa nokuqaliswa kwangaphambi kwesikhathi. Ukuqala kwenjini kungenzeka uma:

• ukufaka i-refueling ngephethiloli yekhwalithi ephansi (isibonelo, ngenombolo ye-octane ephansi);
• ukuguga kwendlela yokusabalalisa igesi;
• ukusetha okungalungile kwe-engeli yokuthungela ngesikhathi somsebenzi wokuvimbela nokulungisa.

Uma kutholwa isignali yenzwa yokugoqa, iyunithi yokulawula injini ilungisa ukunikezwa kukaphethiloli, inciphisa isikhathi sokuthungela, okungukuthi ilibazisa ukuthungela, ivimbela umphumela wokuqhunyiswa. Uma inzwa ingasebenzi kahle, umphumela wokuqhumisa awukwazi ukugwenywa. Lokhu kungaholela emiphumeleni emibi kakhulu, okungukuthi:

• ukwanda okuphawulekayo komthwalo ezingxenyeni nezindlela zenjini;
• ukungasebenzi kahle kohlelo lokusabalalisa igesi;
• izinkinga ezingathi sína ngesidingo sokushintshwa kwenjini.

Ukwehluleka kwenzwa yokungqongqoza kungenzeka ngenxa yezizathu ezilandelayo:

• gqoka;
• ukulimala komshini ngesikhathi sokulungisa noma kwenzeka ingozi yomgwaqo.

Izindlela zokuqapha ukungasebenzi kahle kwenzwa yokungqongqoza

Uphawu oluyinhloko lwenzwa yokugoqa embi ubukhona bomphumela wokushayisa kwenjini, ozwakala lapho i-accelerator pedal icindezelwa kanzima ngaphansi komthwalo, njengalapho ushayela wehla noma usheshisa. Kulokhu, qiniseka ukuthi uhlola ukusebenza kwenzwa.

Indlela enokwethenjelwa kakhulu yokuthola ukungasebenzi kahle kwe-Accord 7 engine knock sensor iwukuxilonga ngekhompyutha. Ikhodi yephutha engu-P0325 ihambisana nephutha lenzwa yokushaya. Ungasebenzisa futhi indlela yokulawula ipharamitha. Ukuze wenze lokhu, inzwa kufanele isuswe. Kuyadingeka futhi ukusebenzisa i-voltmeter ye-AC ezwela kakhulu (ungasebenzisa i-multimeter njengendlela yokugcina, usethe ukushintshela emkhawulweni ophansi ukuze ulinganise i-voltage ye-AC) noma i-oscilloscope ukuze uhlole izinga lesiginali phakathi kwekesi nokuphuma kwenzwa ukwenza amaqhubu amancane kudivayisi.

I-amplitude yamasignali kufanele okungenani ibe ngu-0,5 volts. Uma inzwa ilungile, udinga ukuhlola izintambo ezisuka kuyo ziye kuyunithi yokulawula injini.

Akunakwenzeka ukuhlola inzwa ngethoni yokudayela elula nge-multimeter.

Ukushintsha inzwa yokushaya nge-Accord 7

Inzwa yokungqongqoza itholakala endaweni engalungile yokushintshwa: ngaphansi kwe-multifold intake, kwesokunxele sesiqalisi. Ungabona indawo yayo ngokuningiliziwe emdwebeni wesakhiwo.

Kulo mfanekiso, inzwa iboniswa endaweni ye-15.

Ngaphambi kokudiliza inzwa yokugoqa, kuyadingeka ukuphatha indawo yokufaka inzwa ngeshidi lensimbi noma okunye ukwakheka okukhethekile ukususa i-coke, ngoba ngesikhathi sokusebenza kwakusesimweni esinamafutha emazingeni okushisa aphezulu.

Inzwa entsha yokungqongqoza ayibizi. Isibonelo, inzwa yoqobo eyenziwe eJapan ngaphansi kwesihloko esithi 30530-PNA-003 ibiza cishe ama-ruble ayi-1500.

Ngemva kokufaka inzwa entsha, kufanele usethe kabusha amaphutha enjini usebenzisa isithwebuli sokuxilonga.
