GDI-injini: kweguyo kunyanya

GDI-injini zvinoreva vezvikwata pamwe zvakananga mafuta jekiseni, umo mafuta muvhenganiswa asingadi kupinda mukati pasi kudya siyana, uye kamwe dzomunyika injini sepombi. Panguva iyoyo, zvakadai zvirimwa simba akapera motokari akaita kuJapan. Kunyanya, "Toyota", "Nissan" uye "Mitsubishi".

GDI-injini uye midziyo

Saka, ngatitarise magadzirirwo zviri chikwata ichi. Sezvataona, iri GDI-injini ine yakananga mafuta jekiseni kupinda sepombi, izvo zvakaita kuti tikwanise kuderedza avhareji mafuta kudyiwa anosvika 20-30 kubva muzana. Uyewo, chikwata ichi kunoratidzwa chokwadi kuti diki uye svikiro mitoro inouya stratified mutariri. Panyaya iyi, chinotsva zvokudya kupinda injini humburumbira kufurirwa pamwe GDI anenge 100 atmospheres, saka kuti hazvina vanokwanisa kuwana okisijeni yakakwana. Enzanisa mu kwakajairika mafuta jekiseni injini kwepfumo kunoitika panguva kumanikidzwa 3 ATM. Nokuda kwaizvozvi, chikamu mafuta unorambira chinopa chivhariso, uye chaiyo nechinguvana sparking.

Kana munhu akapiwa kwazvo huni anopinda yaunodya siyana, noruvara unozadza bhuku rose, nokudaro wezvamatongerwe nokukurumidza evaporating uye dzakaonda. Muchiitiko chino, pasina kupinda reokisijeni gasi haangavi kupisa, uye yakawanda iri rinongoreva rinobhururukira iri kumicheto. Kazhinji Muzviitiko zvakadaro, injector imotokari overheats uye makenduru, chena chin'ai. Chii chinoitika kuna GDI-injini? Hazvina kuumba deposits zvakadaro, nekuti magadzirirwo ayo haisi iyo throttle vharuvhu. It, uyewo, inobudisa kunze mhepo uye akariisa kupinda humburumbira (ichi kunoitika pamberi kwegadziriro huni mhepo masanganiswa). Panyaya iyi, injini asingadi kutambisa simba rayo mumhepo yaunodya, riri kazhinji 3-5 zvishoma horsepower. Uyewo, GDI injini 18 kuzivikanwa kwayo yakakwirira pamwero compression, iro kubudirira nokuda iyoyo kushaya throttle.

Zvinofanira kucherechedzwa kuti yunifomu rukoko reokisijeni aumbwa, mauri musanganiswa unopisa uye inobudisa pisitoni kuti humburumbira masvingo panguva combustion nokukurumidza. Uye kuti GDI-injini panguva kunonyanyisa mutoro? Kana nyaya mbiri dzokutanga, nheyo stratified vebasa, zvino ichi hachisi panguva zvizere mutoro. The huni iyi anopinda humburumbira ari makuru mari, uye kwete sezvinoita kare, nemhaka iyo anowedzera kuerera mwero uye wevasungwa pamwero zvinokuvadza ari chiutsi gasi panguva nzira yokubudisa. Nokuda kwechikonzero ichi injini zvose ano takashongedzerwa zvimwe GDI injectors pamusoro yaunodya zvawanda. Vanogona kuderedza huni kunwa kusvikira pachiyero kwakajairika motokari pamwe huni-jekiseni dzakabatana. Saka, kunonyanyisa mitoro unoparadza zvakaenzana huni, uye outputs yakakodzera simba injector sezvo kwakajairika Motors.

How chidzore nesimba ichi?

Kazhinji, kufadza mutoro pamusoro injini GDI-chete chinotanga nokumhanya makiromita 120 paawa, saka kakawanda zvemari chikwata kungonyanya mafuta.
