I-Cast Iron vs Cast Steel: Iyiphi Inqwaba Ethuthukisa Ukusebenza?

Ama-manifold adlala indima ebalulekile ekusebenzeni kwenjini. Lezi zingxenye zeshaneli zikhipha amagesi kude nenjini, zibe nomthelela ekusebenzeni kahle nokuphuma kwamandla. Ukukhethwa kwempahla yeqeda ngokuphindaphindiwekunomthelela omkhulu ekusebenzeni kwayo. I-cast iron exhaust eninginingi inikezela ukuqina nokugcinwa kokushisa, ikwenze kube ukukhetha okudumile. Nokho,intuthuko kwezobuchwepheshe bezinto ezibonakalayobaye bethula ezinye izindlela ezifanainsimbi, enikeza amandla athuthukisiwe nokumelana nokugqwala. Ukuqonda lo mehluko kukusiza ukuthi wenze izinqumo ezinolwazi ezithuthukisa ukusebenza kwemoto.

Ukuqonda Izinhlobonhlobo

Iyini i-Manifold?

Incazelo kanye Nomsebenzi

I-manifold isebenza njengengxenye ebalulekile ohlelweni lwe-exhaust lwenjini. I-manifold iqoqa amagesi e-exhaust asuka kumasilinda amaningi abe yipayipi elilodwa. Le nqubo iqinisekisa ukuxoshwa okuphumelelayo kwamagesi enjini. Idizayini ye-multifold inomthelela ekutheni amagesi ageleza ngempumelelo, okuthinta ngqo ukusebenza kwenjini.

Izinhlobo Eziningi

Izinhlobonhlobo ziza ngezinhlobo ezahlukene, ngayinye ilungele izinhlelo zokusebenza ezithile. Izinhlobo ezimbili eziyinhloko zifaka i-exhaust manifolds kanye ne-multifold intake. I-exhaust eningi ikhipha amagesi esiteshi kude nenjini, kuyilapho ama-manifolds athathayo asabalalisa umoya kumasilinda enjini. Uhlobo ngalunye ludlala indima ehlukile ekugcineni ukusebenza kahle kwenjini.

Ukubaluleka Ekusebenzeni Kwenjini

Umthelela Ekusebenzeni Kahle

Amanifolds anomthelela kakhulu ekusebenzeni kahle kwenjini. Ama-manifolds aklanywe kahle athuthukisa ukugeleza kwamagesi e-exhaust, anciphisa ukucindezela emuva. Lokhu kuncipha kuholela ekusebenzeni kahle kukaphethiloli kanye nokukhuphuka kwamandla okukhipha amandla. Ucwaningo lwaqokomisa lokhoinsimbi eningi, ikakhulukazi izinguqulo zensimbi engagqwali, zinganciphisa ukulahlekelwa ukushisa, okuholela ekwandeni kwamandla ehhashi nokusebenza.

Iqhaza Ekulawuleni Ukungcola

Ama-manifolds nawo adlala indima ebalulekile ekulawuleni ukungcola. Ngokuhambisa kahle amagesi e-exhaust, ama-multifolds asiza ukugcina ukukhishwa okuphansi. Idizayini nempahla ye-multifold inomthelela ekutheni ilawula kahle kangakanani ukukhishwa kwegesi. Isibonelo, izimbobo ze-ceramic kuma-manifolds zinganciphisa izinga lokushisa, okuthuthukisa ukusebenza kwezinhlelo zokwelapha ngemuva. Lesi sithuthukisi sinomthelela ekungcolisweni kwesisi esihlanzekile kanye nokuthotshelwa kwemvelo okungcono.

Izinto ezibonakalayo

I-Cast Iron Exhaust Manifold

Ukuqanjwa kanye Nezimpawu

I-cast iron exhaust manifold iqukethe insimbi exutshwe ne-carbon ne-silicon. Lokhu kwakheka kunikeza ukugcinwa kokushisa okuhle kakhulu nokuqina. Izindonga eziwugqinsi ze-cast iron zisiza ekuvimbeleni inqwaba, okunciphisa izinga lokushisa ngaphansi kwe-hood.
