Ezinjinini eziningi zokukhiqiza, i ngokuphindaphindiwe iyinhlangano eklanyelwe ukuqoqa igesi yokukhipha igesi kusuka kumasilinda amabili noma ngaphezulu ibe yipayipi elilodwa. Ama-manifolds ngokuvamile enziwa ngensimbi esakazwayo ezimotweni zokukhiqiza isitoko, futhi angase abe nezici zedizayini ezonga izinto ezifana nokusebenzisa insimbi encane, ukuthatha indawo encane kakhulu edingekayo, noma ukuba nezindleko eziphansi zokukhiqiza. Le mikhawulo yokuklama ivamise ukuphumela ekwakhiweni okungabizi kakhulu kodwa okungawenzi umsebenzi osebenza kahle kakhulu wokukhipha amagesi enjinini. Ukungasebenzi kahle ngokuvamile kwenzeka ngenxa yemvelo yenjini evuthayo namasilinda ayo. Njengoba amasilinda evutha ngezikhathi ezihlukene, igesi ekhipha umoya iyawashiya ngezikhathi ezihlukene, futhi amaza okucindezela egesi aphuma kusilinda esisodwa angase angaphumi ngokuphelele kumshini wokukhipha umoya lapho kufika omunye. Lokhu kudala umfutho ongemuva kanye nomkhawulo ohlelweni lokukhipha umoya wenjini olungakhawulela ukusebenza kwangempela kwenjini.
Kungakhathaliseki ukuthi yiziphi izici ezingezinhle ezigxilwe kuzo abathengisi abangaba khona bemishini yokukhipha umoya weshubhu lensimbi, onjiniyela abaklama izingxenye zenjini bakhetha ama-multifold exhaust yensimbi esakazwa ngokufanayo bangakwazi ukuklelisa izici ezinhle, njengohlu lwezindawo zokulawula ukushisa nokuhlala isikhathi eside kunanoma yiluphi olunye uhlobo lwe ukwakhiwa kwe-outlet exhaust. Kumthengi ojwayelekile, ukuba nenkinga nganoma yiziphi izingxenye ze-exhaust kungase kudingeke 'ukusebenza kabi'.
A unhlokweni iyinqwaba eklanyelwe ukusebenza.[1] Ngesikhathi sokuklama, onjiniyela benza a ngokuphindaphindiwe ngaphandle kokubheka isisindo noma izindleko kodwa esikhundleni sokugeleza kahle kwamagesi aphumayo. Lo mklamo uphumela kunhlokweni osebenza kahle kakhulu ukuphanga ukuphuma kwamasilinda. Izihloko ngokuvamile ziyishubhu yensimbi eyindilinga egobayo kanye nokugoqeka okubalwe ukuze kwenziwe imizila esuka embotsheni yokukhipha umoya yesilinda ngayinye kuya endaweni evamile yokuthenga ngobude obulinganayo, futhi ihlanganiswe ngama-engeli amancane ukuze kukhuthazwe amagagasi okucindezela ukuba ageleze endaweni, futhi angabuyeli abheke kwamanye amasilinda. Kusethi ye kuthungiwe izihloko ubude bepayipi bubalwa ngokucophelela ukuze kuthuthukiswe ukugeleza kwe-exhaust ebangeni elithile lenjini ngomzuzu (RPM) ububanzi.
