Knock inzwa Chevrolet Niva
Okuqukethwe
Ukuqhuma okwenzeka ngesikhathi sokusebenza kwenjini akugcini nje ngokudala ukudlidliza okwephula induduzo yeChevrolet Niva, kodwa futhi kunomthelela omubi enjinini. Ilimaza kancane kancane izakhi zeqembu le-cylinder-piston futhi ilethe isidingo sokulungiswa okuphelele kwesitshalo samandla eduze.
Ukulwa nokuqhunyiswa, kusetshenziswa iyunithi yokulawula ye-elekthronikhi ethola ulwazi mayelana nokusebenza kwenjini nge-DD. Kuye ngedatha etholiwe, isikhathi sokuthungela kanye nokwakheka kwengxube ye-air-fuel kuyalungiswa.
Inhloso yesenzwa sokungqongqoza
Inzwa yokungqongqoza imise okwe-toroid eyindilinga. Kunembobo phakathi lapho kudlula khona ibhawodi elifakwayo. Futhi ku-DD kukhona isixhumi. Ihlinzeka ngoxhumano lukagesi lwemitha kuyunithi yokulawula ye-elekthronikhi yesikhungo samandla. Ngaphakathi kwe-torus kunesici se-piezoelectric. Ukudlidliza okwenzeka ngesikhathi sokuqhunyiswa kubangela ukushaqeka kwezindleko, eziguqulelwa i-DD zibe isignali kagesi yefrikhwensi ethile kanye ne-amplitude.
I-ECU ilawula i-voltage evela ku-DD. Umehluko phakathi kwe-amplitude kanye nemvamisa yohlu olujwayelekile lwamanani kukhombisa ukwenzeka kokuqhunyiswa. Ukuyiqeda, iyunithi yokulawula ilungisa ukusebenza kwenjini.
Ukuqeda ukudlidliza okudlulele kanye nokungqongqoza kunciphisa imithwalo ephula izinambuzane ku-powertrain. Ngakho-ke, inhloso eyinhloko ye-DD kuwumsebenzi wokunquma ngesikhathi sokuvela kokuqhunyiswa nokwandisa impilo yesevisi yenjini. Isithombe esilandelayo sibonisa idayagramu yokuxhumeka kwe-DD.
Indawo yenzwa yokungqongqoza ku-Niva Chevrolet
Indawo ye-DD yenziwe ngendlela yokuthola ukuzwela okuphezulu kakhulu kwenzwa. Ukuze ubone ukuthi i-gauge yokucindezela ikuphi, udinga ukubheka ngqo ku-cylinder block. Inzwa ivuliwe. Ungakwazi ukunquma ukuthi ikuphi inzwa ngokulandela izintambo eshubhu likathayela elisuka kukhompuyutha liye kuyinzwa.
Izindleko zenzwa
Inzwa yokungqongqoza inokugcinwa okuphansi kakhulu. Ngokuvamile, lapho ihluleka, kudingeka ukushintshwa nge-DD entsha. Inzwa yokuqala yeGeneral Motors inenombolo yengxenye 21120-3855020-02-0. Intengo yayo ingama-ruble angama-450-550. Uma udinga ukushintsha i-DD, ungathenga i-analogue. Ithebula elilandelayo libonisa ezinye izindlela ezingcono kakhulu zemikhiqizo enebhrendi.
Ithebula - Ama-analogue amahle we-Chevrolet Niva knock sensor yasekuqaleni
| Mdali | Ikhodi yomhlinzeki | Izindleko ezilinganiselwe, hlikihla |
|---|---|---|
| Ihlathi | 0 261 231 046 | 850-1000 |
| I-Fenox | I-SD10100O7 | 500-850 |

Izindlela zokuhlola inzwa ye-Knock
Lapho kuvela izimpawu zokuqala zokungasebenzi kahle kwe-DD, ngaphambi kokuthatha isinqumo sokuyishintsha, kuyadingeka ukuhlola ukusebenza kwemitha. Okokuqala, udinga ukunaka ukuthi kukhona yini iphutha esikrinini sekhompyutha esisebhodini. Uma i-DD inikeza ileveli yesiginali ephezulu kakhulu noma ephansi, izinto zikagesi zibhalisa lokhu bese umshayeli ethola isexwayiso.
Kungenzeka ukuhlola ngokunembile ukusebenza kwe-DD kuphela endaweni yokuma. Zonke ezinye izindlela zibonisa kuphela ngokungaqondile ukusebenza kwedivayisi.
Okokuqala, kubalulekile ukuhlola ukumelana phakathi koxhumana nabo. Esimeni esijwayelekile, kufanele ibe ngu-5 MΩ. Noma yikuphi ukuchezuka okubalulekile kubonisa ukungasebenzi kahle kwemitha.
Enye indlela yokuhlola isilinganiso se-voltage. Kulokhu kufanele:
- Susa inzwa.
- Xhuma i-multimeter noma i-voltmeter kumatheminali.
- Ngento encane yensimbi, efana nophini noma ibhawudi, shaya i-toroid yekhawunta esebenzayo.
- Hlola ulwazi lwedivayisi. Uma kungekho ukuphakama kwamandla, khona-ke inzwa ayifanele ukusebenza okwengeziwe. Kubalulekile ukuqaphela ukuthi ngisho nokuba khona kokuphakama kwamandla kagesi akusona isizathu sokucabangela ukuthi i-DD isebenza ngokugcwele. I-ECU isebenza ebangeni elincane lama-amplitudes nama-frequency, ukuxhumana okungenakubanjwa nge-multimeter noma i-voltmeter.
Ukuze ngokuzimela ushintshe inzwa yokungqongqoza emotweni ye-Chevrolet Niva, kufanele ulandele imiyalelo engezansi.
- Nqamula ibhulokhi yetheminali.
- Hambisa isixhumi eceleni ukuze singaphazamisi ukususwa okulandelayo.
- Usebenzisa ukhiye othi “13”, khumula ibhawudi yokukhweza ye-DD.
- Susa inzwa.
- Faka inzwa entsha.
- Xhuma isixhumi.
