Tsarin Camshaft: filastik maimakon ƙarfe

Sabon samfurin yayi alƙawarin fa'idodi dangane da nauyi, farashi da mahalli

Arfafa tare da guduro na roba maimakon aluminum.

Wannan shine abin da masana kimiyya a Fraunhofer Institute for Chemical Technology (ICT) suke yi. Tare da masana daga Daimler, Mahle da sauran masu samar da kayan kera motoci, sun kirkiro wani sabon nau'I na samfurin camshaft wanda aka yi shi da filastik maimakon gami mai haske. Modulea'idodin abu ne mai mahimmanci na ƙirar tuki, don haka kwanciyar hankali shine mafi mahimmancin buƙata ga masu zane. Koyaya, Fraunhofer yana amfani da babban ƙarfi, mai ɗaure zafin jiki na thermosetting polymer (resins na roba) maimakon aluminium don ƙirar da ke aiki azaman rukunin kamshaft.

Mawallafin ci gaban suna jayayya cewa wannan zai kawo fa'idodi da yawa a lokaci guda. Ta wani bangare, dangane da nauyi: “Tsarin camshaft yana nan a cikin silinda, wato galibi a saman hanyar tuki,” in ji Thomas Sorg, masanin kimiyya a Cibiyar Fraunhofer. Anan, ajiyar nauyi suna da amfani musamman yayin da suke rage tsakiyar abin hawan. " Amma ba kawai kyau bane ga mahimmancin hanya. Rashin nauyi yana ɗayan ɗayan mahimman hanyoyin don rage hayaƙin CO2 daga motoci.

Kudin kuɗi da fa'idodin yanayi

Kodayake bangaren da aka kirkira a makarantar ya fi na aluminum camshaft sauki, masu yin sa suna da'awar cewa yana da matukar tsayayya da yanayin zafi da damuwar inji da na sinadarai, kamar wadanda ke faruwa ta hanyar mai mai roba da sanyaya. Acoustically, sabon ci gaban kuma yana da fa'idodi. Saboda robobi suna yin aiki kamar insulators masu sauti, "halayyar kwastomomi ta tsarin camshaft ana iya inganta ta sosai," in ji Sorg.

Koyaya, babban fa'ida na iya zama ƙananan farashi. Bayan yin simintin gyare-gyaren, sassan aluminium dole ne ayi aikin gamawa mai tsada kuma suna da takaitaccen rayuwa. Idan aka kwatanta, farashin ƙarin aiki na kayan haɓakar zafin jiki mai ƙarfafuwa yana da ɗan kaɗan. Monirƙirarin haɗin kansu yana ba da damar ɓangaren da za a sarrafa shi a cikin masana'anta, inda za a ɗora shi zuwa injin ɗin tare da 'yan kaɗan motsi kawai. Kari akan haka, Fraunhofer ICT yayi alkawarin karin dorewa sosai don sabon cigaban sa.

A halin yanzu, camshaft module na Cibiyar ICT. Fraunhofer har yanzu yana kan matakin ƙirar nunin aiki. A kan bencin gwajin injin, an gwada sashin na sa'o'i 600. "Mun yi matukar farin ciki da samfurin aiki da sakamakon gwajin," in ji Catherine Schindele, manajan aikin a Mahle.
