I-waveform clutter ye-oxygen sensor ibangelwa yi-cylinder ene-ignition embi. Ingaba ukuvutha kakubi kwe-injini kubangela njani ukugcwala?

I-burr kunye ne-clutter kwi-waveform phantsi kwemeko yokutshisa okungahambi kakuhle kubangelwa ixesha elilodwa lokutsha okanye uchungechunge lweziganeko zokutsha ezinokutsha okungaphelelanga okanye kungabikho, okukhokelela ekubeni inxalenye ye-oxidation esebenzayo isetyenziswe kwi-cylinder, kwaye i-oksijini eseleyo eseleyo iya umbhobho wokukhupha kwaye udlula kwinzwa ye-oxygen. Xa inzwa ibona utshintsho lokubunjwa kwe-oksijini kwigesi yokukhupha, iya kuvelisa uxinzelelo oluphantsi okanye i-burr ngokukhawuleza, kwaye uchungechunge lwale mibhobho ephezulu-frequency iya kwenza into ebizwa ngokuba yi "clutter".

Iindidi ezahlukeneyo zokutshisa okungalunganga okuvelisa i-burrs.

A) Umlilo ongalunganga obangelwa yinkqubo yokutshisa (umzekelo, iiplagi ze-spark ezonakalisiweyo, imigca yombane ophezulu, izigqubuthelo zokusabalalisa, iintloko zokusabalalisa, iikhoyili zokutshisa okanye iingxaki eziphambili zokutshisa ezichaphazela kuphela isilinda esinye okanye ipere yeesilinda). Ngokuqhelekileyo i-oscilloscope yokutshisa ingasetyenziselwa ukumisela ezi ngxaki okanye ukuphelisa ezi mpazamo);

B) Umlilo ohluphekileyo (izizathu ezahlukahlukeneyo ezinokwenzeka) ezibangelwa umxube ocebileyo othunyelwe kwi-cylinder malunga ne-13: 1 kumlinganiselo onikiweyo we-air-fuel yomxube onobungozi;

C) Umlilo ongalunganga (izizathu ezahlukeneyo ezinokwenzeka) ezibangelwa ngumxube omncinci kakhulu we-air-fuel othunyelwe kwi-cylinder yi-17: 1 kumxube onikiweyo we-air-fuel onobungozi;

D) Ukutshatyalaliswa okungahambi kakuhle okubangelwa ukunyanzeliswa kwe-cylinder, okubangelwa iingxaki zemishini, kunciphisa uxinzelelo lomxube we-fuel-air ngaphambi kokutshisa kwaye awukwazi ukuvelisa ukushisa okwaneleyo, okuthintela ukutsha kunye nokwandisa umxholo we-oksijini kwigesi yokukhupha. (ezifana nokutshiswa kwevalve, ukuphuka kweringi yepiston okanye ukunxitywa, ukunxitywa kwekhamera, ukuncamathela kwevalvu, njl.);

E) I-cylinder enye okanye iisilinda ezininzi zineziphene ezibangelwa ukuvuza kwe-vacuum, enokuthi igqitywe ngokudibanisa ipropane kwindawo ekrokrelwayo yokuvuza i-vacuum (i-intake impeller, i-pad manifold pad, i-vacuum tube, njl.). Jonga xa i-waveform ye-oscilloscope iba yimiqondiso emininzi kwaye incopho iyanyamalala ngenxa yokongezwa kwepropane. Xa umxube ungena kwi-cylinder ngenxa yokuvuza kwe-vacuum ehambelana ne-cylinder enye okanye iisilinda ezininzi zidlula i-17: 1, ukuvutha kakubi okubangelwa ukuvuza kwe-vacuum kwenzeka.
