Iindidi ezahlukeneyo zokutshisa okungalunganga okuvelisa i-burrs.

Ukuvutha kakubi okubangelwa sisitofu esingalungelelananga semilomo kuphela kwiinjini ezinamanqaku amaninzi. Ukuvutha kakubi okubangelwa ngumxube otyebileyo okanye obhityileyo we-oyile kwi-cylinder enye kubangelwa yi-oyile eninzi kakhulu okanye encinci kakhulu eneneni etofweyo ngombhobho ngamnye (umlomo uvalekile okanye ubambekile). Xa umlinganiselo wamafutha omoya womxube wamafutha omoya kwisilinda esinye okanye iipetroli ezininzi udlula ingozi, ukuvutha kakubi kwenzeka xa umlinganiselo wepetroli yomoya ungaphezulu kwe-17: 1, kwaye ukuvutha kakubi kwenzeka xa umlinganiselo wepetroli womoya ungaphantsi kwe-13: I-1, ebangela ukuvutha kakubi okubangelwa yinaliti ye-fuel engalinganiyo evela kwi-injector fuel. Ngokuqhelekileyo, inokugwetywa ngokungabandakanyi ukungabikho kokuvutha okungahambi kakuhle okubangelwa yinkqubo yokutshisa, ukuvutha kakubi koxinzelelo lwe-cylinder kunye nokuvuza kwe-vacuum ye-cylinder enye. Isitofu samafutha esingalungelelananga. I-oscilloscope ye-automobile ingasetyenziselwa ukuphelisa ukutshisa okungahambi kakuhle okubangelwa yinkqubo yokuzitshisa kunye noxinzelelo lwe-cylinder (ukufumana ukutshatyalaliswa okungahambi kakuhle okubangelwa yinkqubo yokucima kunye nengxaki yoxinzelelo lwe-cylinder balance dynamic). Ukuphelisa ukuvuza kwe-vacuum ehambelana neesilinda ezizimeleyo, ipropane (i-manifold intake, carburetor pad, njl.njl.) ihlala yongezwa kwindawo okanye ejikelezileyo apho ukuvuza kwe-vacuum kunokuthi kwenzeke khona, kwaye kwangaxeshanye, njengoko bekutshiwo ngaphambili, isibonakaliso somqondiso we-oxygen waveform. Inzwa ijongwa kwi-oscilloscope ukufezekisa injongo. Ngokuqhelekileyo, kwi-injini ye-injini yamanqaku amaninzi, ukuba i-misfire ebangelwa yi-A, B, kunye ne-C ayinakubonakaliswa, ngoko kunokwenzeka ukungalingani okubangela i-clutter enzulu kwi-waveform ye-oxygen sensor. Imithetho yokugweba i-clutter ye-oxygen sensor Ukuba kukho i-clutter ecacileyo kwisignali ye-oxygen sensor, engaqhelekanga kwinkqubo egwebayo, ngokuqhelekileyo iya kukhatshwa ngokuphindaphindiweyo kunye nokungaphumeleli kwe-injini kwisantya sokungasebenzi (umzekelo, ukubetha kwi-cylinder nganye. ukulayita). Ngokuqhelekileyo, ukuba i-clutter icacile, impazamo ye-injini ekugqibeleni iya kuhambelana neencopho ezahlukeneyo kwi-waveform, kwaye i-clutter ngaphandle kwempazamo ecacileyo ye-injini akulula ukuyiphelisa (echanekile kwezinye iimeko), oko kukuthi, xa iincopho zomntu ngamnye kwi-waveform azinanto yakwenza nempazamo ye-injini, akunakwenzeka ukuba kupheliswe ekulungiseni. Ukushwankathela, umgaqo wokugweba i-clutter ngulo: Ukuba kunokugqitywa ukuba akukho ukuvuza kwe-vacuum kwi-intake manifold, imixholo ye-hydrocarbons (HC) kunye ne-oksijini kwigesi yokukhupha iyinto eqhelekileyo, kwaye ukujikeleza okanye isantya sokungenzi lutho. i-injini ilungelelene ngokwentelekiso, ngoko ke i-clutter inokwamkeleka okanye yesiqhelo.
