Inkqubo yokudilizwa kweperi yomlomo wesitofu(icandelo 1)

1.1 Ukucoca

Gxila umbhobho wesitofu ukuze ulungiswe kwi-oyile ye-diesel ekhanyayo iiyure ezininzi, uze uyikhuphe, kwaye uhlambe umphezulu ngebrashi yocingo olucikizekileyo lobhedu ukususa umhlwa, i-oyile kunye ne-carbon deposits.

1.2 Sebenzisa isixhobo esikhethekileyo ukucima umngxuma ophezulu we-injector

Sebenzisa ucingo lwentsimbi olunobubanzi obuyi-1.5mm ukucola umphetho kwaye udilize zonke iidiphozithi zekhabhoni kunye nobumdaka obungaphakathi kumjelo wokungena kwe-oyile womzimba wombhobho wesitofu.

Lola isixhobo sokuphinda sisebenze ngendlela efanayo kumngxuma we-oyile kumzimba womlomo wesitofu, kwaye ususe zonke iidiphozithi zekhabhoni kunye nobumdaka obukwigumbi lokugcina i-oyile.

Ukuba umlomo wesitofu kunye nomzimba we-injector ziyanamathelana, sebenzisa isixhobo esikhethekileyo sokususa ukususa umbhobho wesitofu obambekayo.Musa ukusebenzisa iipliyisi ukukhupha umbhobho wesitofu, okanye ubambe umphini wesitofu kwivise ukuze uyibhutyuze, ukunqanda eminye imilomo yesitofu ukuba ingagotywa kwaye yophuke isiphatho sombhobho wesitofu kunye nokuchithwa.Kwi-nozzle ye-injector ekungekho lula ukuyichitha ngezixhobo ezikhethekileyo, inokufakwa kwi-oyile ye-injini kwaye ifudunyezwe malunga ne-150.°C, kwaye emva koko ikhutshwe kwaye yachithwa ngelixa kuseshushu.

1.3 Ukuhlolwa

Emva kokucoca, khangela zonke iinxalenye ze-injector ye-fuel, ngakumbi i-nozzle ye-injector pair, ukugqiba ukuba utshintshe okanye ulungise.Isikhokelo se-cylindrical sombhobho we-injector mnyama, kwaye ngelo xesha, i-nozzle ye-injector ifakwe kwi-nozzle ye-injector kwaye ivakalelwa kukuba ikhululekile, ebonisa ukuba indawo yesikhokelo ine-gap enkulu.Xa kusetyenziswa, kufuneka kubekho ukubuya kweoli eninzi, kwaye uxinzelelo lweoyile alukwazi ukulungiswa phezulu.Ukuzama ukunyusa uxinzelelo lwe-oyile kunokubangela ukuba uxinzelelo olulawula intwasahlobo lungaphumeleli, kwaye i-oyile ayiyi kutshizwa.
