GDI-motor: idivayisi iphinde ikakhulukazi

GDI-injini libhekisela amayunithi nge ngqo fuel injection, lapho uphethiloli ingxube akusho ukungena we ezininginingi eyanele, futhi uma yangaphakathi omlilo injini amasilinda. Okwamanje, izitshalo ezifana amandla kuyaqedwa izimoto ezenziwe e-Japan. Ikakhulu, i-"Toyota", "Nissan" futhi "Mitsubishi".

GDI-izinjini kanye nemishini

Ngakho, ake sibheke izici design yalolu phiko. Njengoba sesiphawulile, le GDI-injini has oqondile fuel injection ku amasilinda, okuyinto kwenza ukuba kakhulu ukunciphisa isilinganiso petrol ka angu-20-30. Futhi, lolu phiko libhekene yokuthi imithwalo amancane naphakathi kuziwa icala wakubo. Kulokhu, uphethiloli kufakwa ingcindezi injini isilinda nge GDI mayelana 100 eziphindwe, ukuze akusho ukuphatha ukuthola umoya-mpilo ngokwanele. Ukuze uqhathanise, ngo ezivamile fuel injection izinjini Siyafulesha kwenzeka ngesikhathi ingcindezi 3 atm. Ngenxa yalokhu, ingxenye fuel uhlala plug inhlansi, futhi okwamanje esiqondile isusa.

Lapho eliningi inikezwe uphethiloli engena ezininginingi eyanele, ke nombala igcwalisa wawuqeda wonke lo mqulu, kanjalo zakha isimiso ngokushesha ahwamukayo futhi mafutha. Kulokhu, ngaphandle Ukungena komoya-mpilo igesi ngeke bashise, futhi iningi kumane nje endiza tube. Ngokuvamile e Ezimweni ezinjalo, injector izimoto overheats namakhandlela, a umule emhlophe. Kwenzakalani GDI-injini? Ingeyona ezifakwa enjalo, ngoba nje umklamo walo akuyona valve mpintsha. It yena, ithumba emoyeni ngaphandle azikhulule kube uMbhalo (lokhu kwenzeka ngaphambi ukulungiswa ingxube fuel-air). Kulokhu, motor akusho ukuchitha amandla alo ku edonsa emoyeni, okuvamise 3-5 amahhashi kancane. Futhi, GDI injini 18 is zihlukaniswa izinga yayo eliphezulu kokucindezelwa, okuyinto ibangelwa ngenxa ukuntuleka efanayo mpintsha.

Kufanele kuqashelwe ukuthi kwakheka ungqimba iyunifomu oksijini, lapho ingxube wokhela futhi ngokushesha ushayela piston ezindongeni isilinda ngesikhathi omlilo. Futhi indlela GDI-injini at umthwalo esiphezulu? Uma izimo ezimbili zokuqala, isimiso kwenkokhiso wakubo ke lena akuyona at umthwalo omningi. I nophethiloli kuleli cala ingena uMbhalo imali abakhulu, futhi hhayi njengasekuqaleni, ngenxa ngalo kwandisa ukugeleza rate kanye lokuhlushwa ezingeni izinto eziyingozi e-gas qeda kwayo kuleyo ndawo yokuhweba. Ngenxa yalesi sizathu zonke izinjini yesimanje anemisila ezengeziwe GDI injectors phezu ezininginingi eyanele. Abakwazi ukunciphisa petrol kuze kufinyelele ezingeni izimoto ezivamile amayunithi uphethiloli injected. Ngakho, imithwalo esiphezulu ibusa inani elilingana zikaphethiloli kanye Imiphumela ezifanele amandla injector njengoba izinjini ezivamile.

Indlela ukuchaza kulo mzamo?

Ngokuvamile, umthwalo esiphezulu ku injini iqala GDI kuphela nge ijubane amakhilomitha 120 ngehora, ngakho-ke ezimweni eziningi kwezomnotho iyunithi ibusa nophethiloli.
