Ngawaphi amacandelo enkqubo yokukhupha injini
Ukuqokelela igesi yokukhupha kwi-cylinder nganye ye-injini, ukunciphisa ingxolo yokukhupha, susa idangatye kunye ne-spark kwi-exhaust gas, kwaye uhlambulule izinto ezinobungozi kwigesi yokukhupha, ukuze igesi yokukhupha ikhutshwe ngokukhuselekileyo emoyeni. Kwangaxeshanye, inokuthintela amanzi ekungeneni kwi-injini kwaye ikhusele i-injini.
[Ukwakheka kwecandelo lenkqubo yokukhupha injini]: ukukhupha okuninzi, isiguquli sendlela ezintathu, isivamvo seoksijini kunye nesithambiso.
[imisebenzi yamacandelo ahlukeneyo enkqubo yokukhupha injini]: 1. Ukukhupha okuninzi:
Idityaniswe nebhlokhi yesilinda ye-injini ukugxininiswa kwerhasi yokukhupha kwi-cylinder nganye kwi-exhaust manifold.
2. Iindlela ezintathu zokuguqula i-catalytic:
Iigesi ezinobungozi ezifana ne-HC, i-CO kunye ne-NOx (i-nitrogen oxides) kwi-exhaust yemoto iguqulwa ibe yi-carbon dioxide engenabungozi, amanzi kunye ne-nitrogen ngokusebenzisa i-oxidation kunye nokunciphisa.
3. Isivamvo seoksijini:
Isignali ye-air-fuel ratio yomxube ifunyenwe ngokufumanisa umxholo we-oxygen ion kwi-exhaust, eguqulwa ibe ngumqondiso wombane kunye negalelo kwi-ECU. Ngokwalo mqondiso, i-ECU ilungisa ixesha lokutofa ukuze iqonde ulawulo lwempendulo yomlinganiselo we-air-fuel, ukuze i-injini ikwazi ukufumana owona mxube ulungileyo, ukuze kuncitshiswe ukukhutshwa kwegesi eyingozi kunye nokuphucula uqoqosho lwamafutha. (zimbini ngokubanzi, enye isemva kwe-exhaust manifold kwaye enye isemva kwe-tatu-way catalyst. Umsebenzi wayo ophambili kukukhangela ukuba ingaba i-tatu-way catalyst inokusebenza ngokuqhelekileyo.)
4. Isithulisi:
Nciphisa ingxolo yokuphuma. I-silencer ifakwe kwi-outlet yombhobho wokukhupha ukwenza igesi yokukhupha ingene emoyeni emva kokuthulisa. Ngokubanzi, 2 ~ 3 izithulisi zamkelwe. (Isifihli sangaphambili [sisisifingqi esixhathisayo], esisetyenziselwa ukufunxa ingxolo ye-high-frequency; i-muffler yangasemva (i-muffler engundoqo) [i-resistant muffler], esetyenziselwa ukunciphisa ingxolo ye-low-frequency.
