I-Flow Dynamics

Ukubaluleka kokugeleza okushelelayo

Onjiniyela babeka phambili ukugeleza okushelelayo ekwakhiweni kwe-exhaust manifold. Ukugeleza okushelelayo kunciphisa isiyaluyalu ngaphakathi kokuningi. I-turbulence ingadala umfutho ongemuva, okwehlisa ukusebenza kahle kwenjini. I-manifold eklanywe kahle iqinisekisa ukuthi amagesi e-exhaust aphuma kumasilinda enjini ngendlela efanele. Ukuphuma kahle kwegesi kuholela ekusebenzeni okuthuthukisiwe kwenjini nokuphuma kwamandla. I-exhaust manifold kufanele iphathe ukugeleza kwegesi enesivinini esikhulu ngaphandle kokubangela imikhawulo.

Amasu Okuthuthukisa Ukugeleza

Amasu amaningana athuthukisa ukugeleza kwamandla ku-multifold exhaust. Onjiniyela bavame ukusebenzisa mandrel ukugoba ukudala ukugoba bushelelezi emapayipini amaningi. Ukugoba kwe-Mandrel kuvimbela kinks futhi kugcina ububanzi bepayipi obungaguquki. Abagijimi abanobude obulinganayo baqinisekisa ukuthi amagesi e-exhaust avela kusilinda ngasinye afinyelela kumqoqi kanyekanye. Lokhu kuvumelanisa kunciphisa ukuphazamiseka phakathi kwe-exhaust pulses. Abaqoqi abahlanganisa ama-spikes noma ama-cones bathuthukisa futhi ukugeleza kwegesi ngokushelela uguquko.

Ukuphatha Okushisayo

Amasu Okukhipha Ukushisa

Ukukhipha ukushisa okusebenzayo kubalulekile kuma-nifold exhaust. Amazinga okushisa aphezulu angalimaza izingxenye zenjini. Onjiniyela basebenzisa amasu amaningana okuphatha ukushisa. Izivikelo zokushisa zivikela izingxenye ezizungezile emazingeni okushisa angaphezu kwamandla. Izembatho ze-Ceramic endaweni ehlukahlukene zinciphisa ukudluliswa kokushisa. Lezi zimbozo ziphinde zithuthukise ukusebenza kahle kokushisa ngokugcina ukushisa ngaphakathi kokuningi. Ukushisa okugciniwe kuthuthukisa isivinini sokugeleza kwegesi yokukhipha umoya.

Umthelela Ekusebenzeni Kwenjini

Ukuphatha okushisayo kuthinta ngqo ukusebenza kahle kwenjini. Ukukhipha ukushisa ngendlela efanele kuvimbela ukushisa ngokweqile kanye nokulimala okungenzeka kwenjini. I-exhaust eningi eklanywe kahle igcina amazinga okushisa enjini esezingeni eliphezulu. Lokhu kulawulwa kwezinga lokushisa kuthuthukisa ukushiswa kukaphethiloli futhi kunciphisa ukukhishwa kwekhabhoni. Ukusebenza kahle kokushisa okuthuthukisiwe kunomthelela ekuwongeni uphethiloli okungcono kanye nokusebenza kwenjini kukonke. I-exhaust eningi idlala indima ebalulekile ekugcineni lezi zimo ezishisayo.

Ukugcinwa kanye nokuxazulula izinkinga ze-Engine Exhaust Manifold

Izinkinga Ezivamile

Imifantu kanye Nokuvuza

Imifantu ku-exhaust eningi ngokuvamile ibangelwa ukucindezeleka okushisayo. Le mifantu ingaholela ekuvuzeni kwe-exhaust, okuthinta ukusebenza kwenjini. Ukuvuza kuvumela amagesi ayingozi ukuthi abaleke ngaphambi kokufinyelela kusiguquli se-catalytic. Lokhu kuphunyuka kunciphisa ukusebenza kahle kohlelo lokulawula ukungcola. Ukuhlola njalo kusiza ukuhlonza imifantu kusenesikhathi. Ukutholwa kusenesikhathi kuvimbela ukulimala okwengeziwe ezingxenyeni zenjini.

I-Warping kanye nokuhlanekezela

I-Warping kwenzeka ngenxa yokushisa okungalingani kanye nemijikelezo yokupholisa. Ukuphindaphindeka okuhlanekezelwe kungabangela ukungahambi kahle nebhulokhi yenjini. Ukungaqondi kahle kuholela ekuvaleni okungafanele kanye nokuvuza okungenzeka. Ukuphindaphindeka okusontekile kungase futhi kukhiphe imisindo engajwayelekile ngesikhathi sokusebenza kwenjini. Ukuqapha ukuguquguquka kwezinga lokushisa kusiza ukuvimbela ukulwa. Ukuphatha ukushisa ngendlela efanele kunweba ubude besikhathi sokuphila kokuningi.

Amathiphu Okunakekela

Izinqubo Zokuhlola Okuvamile

Ukuhlola okuvamile kuqinisekisa ukuphila isikhathi eside kwe-exhaust manifold. Ukuhlola okubonakalayo kokuqhekeka nokuvuza kubalulekile. Lalela imisindo engajwayelekile ekhombisa izinkinga eziningi. Hlola amabhawodi akhwezayo ukuze aqine ukuze uvimbele ukudlidliza. Hlola izimpawu zokugqwala noma ukugqwala endaweni ehlukahlukene. Ukuhlola okuvamile kusiza ukugcina ukusebenza kwenjini okuseqophelweni eliphezulu.

Izincomo Zokuhlanza Nokunakekela

Ukuhlanza i-exhaust manifold kususa amadiphozithi e-carbon. I-carbon buildup ithinta ukuhamba kwamagesi e-exhaust. Sebenzisa ibhulashi locingo ukuze uhlanze indawo eningi. Faka upende ongashisi ukuze uvimbele ukugqwala nokugqwala. Gwema ukusebenzisa amakhemikhali anokhahlo angalimaza i-multifold material. Ukuhlanza kahle kuthuthukisa ukusebenza kahle kwesistimu yokukhipha umoya.

Izinyathelo zokuxazulula inkinga

Ukuhlonza Izimpawu

Ukubona izimpawu zezinkinga eziningi kusiza ekuxazululeni izinkinga. Bheka amandla enjini anciphile kanye nokwenyuka kokusetshenziswa kukaphethiloli. Lalela imisindo yokumaka ephakamisa ukuvuza. Hlola iphunga lamagesi akhipha umoya ngaphakathi endlini yemoto. Gada ideshibhodi ukuze uthole izibani eziyisixwayiso ezihlobene nokukhipha umoya. Ukubona lezi zimpawu kusiza ekuxilongeni izinkinga eziningi.

Izixazululo Nokulungiswa

Izixazululo zezinkinga eziningi ziyahlukahluka kuye ngenkinga. Shintshanisa ama-multifolds aqhekekile noma esonteke kakhulu. Sebenzisa ama-sealant okushisa okuphezulu ukuze ulungise ukuvuza okuncane okwesikhashana. Qinisa amabhawodi axegayo ukuze uqede ukudlidliza nomsindo. Qinisekisa ukuqondanisa okufanele ngesikhathi sokufakwa ukuze uvimbele ukuvuza okuzayo. Cabangela izinsizakalo zokukhanda ezichwepheshile ezindabeni eziyinkimbinkimbi. Ukulungiswa okufanele kubuyisela ukusebenza kahle kwesistimu yokukhipha umoya.

Ibhulogi ihlole indima ebalulekile yedizayini ye-exhaust eningi ekusebenzeni kwenjini. Idizayini efanele iqinisekisa ukugeleza kahle kwegesi yokukhipha futhi ithuthukisa ukusebenza kahle kwenjini. Ukunakekelwa okuvamile kuvimbela ukulungiswa okumba eqolo futhi kugcina ukusebenza kahle. Abafundi kufanele basebenzise lolu lwazi ukuthuthukisa ukusebenza kahle kwenjini. Ukuqondaizisekelo zokugcinwa kwesistimu ye-exhaustkusiza ukuhlonza izinkinga ezivamile. Ukubonisana nochwepheshe besondlo kuyancomeka. Ukusebenzisa le mikhuba kuzoholela ekusebenzeni okungcono kwenjini nokuphila isikhathi eside.
