I-Encyclopedia yezinjini: Mazda 2.0 Skyactiv-G (uphethiloli)

Izigigaba zakwaMazda ngomjovo kaphethiloli oqondile zaqala ngaphambi kokwethulwa kochungechunge lwezinjini ze-Skyactiv, futhi kwaba yimizamo eyimpumelelo kakhulu. Okuhlangenwe nakho kuphenduke injini ekwazi ukumelana nezimbangi ezine-turbocharged kuze kube namuhla.

Umjovo kaphethiloli oqondile wakwaMazda waqala ukuvela ngo-2005 (injini engu-2.3 DISI) kuModel 6. Isizukulwane sesibili iMazda 6 isebenzisa iyunithi engu-2.0 DISI (nayo kuMazda 3), kanye nenjini yeSyactiv-G yaqala ukuvela kuMazda CX5 ngo-2011. futhi iphinde yathola ukusetshenziswa kwayo esizukulwaneni sesithathu i-Mazda 6.

Iyunithi ithuthuke kakhulu kwezobuchwepheshe, futhi, naphezu kokungabikho kwe-boost, inezixazululo ezifana ne-high compression ratio (14: 1), okuyinto ikuvumela ukuthi usebenze kumjikelezo we-Atkinson-Miller, isikhathi se-valve eguquguqukayo noma idizayini engasindi, nakuba idrayivu yesikhathi iqhutshwa iketango. Kukhona nesistimu yokumisa isiqalo kanye nesistimu ye-i-ELOOP evuselela amandla okusebenza ngokushesha. Isihluthulelo sempumelelo, okungukuthi, ukugcina amazinga alungile wokukhipha umoya, ukulawula okunembile kokushiswa kwengxube. Imoto isuka ku-120 iye ku-165 hp, ngakho-ke, inikeza amandla ahloniphekile alesi sigaba semoto, nakuba ihluke ngokucacile "kumazinga we-turbo" wezimbangi.

Ngokwemishini, injini ayikwazi ukonakala. Okuhlala isikhathi eside, uwoyela akuyona inkinga, futhi Iketango lesikhathi 200 izinkulungwane. I-km idinga kuphela ukuhlolwa, ayivamile ukushintshwa. Ikhabhoni emnyama itholakala kuphela ezinjinini ezinamafutha ashintshwa njalo nje. (ubuningi njalo ku-15 km) noma ngemva kokusebenzisa amafutha ane-viscosity engalungile (kunconyiwe 0W-20, 5W- evunyelwe). Abasebenzisi bazabalaze kakhulu nge-hardware.

Ukuvuza kwesistimu ye-exhaust kanye ne-flow meter eyonakele yizona zimbangela ezivame kakhulu zokuqalisa injini noma izinkinga zokukhihla. Kuyaqabukela, i-valve ye-blower yonakaliswe, evuthela uwoyela emagumbini omlilo, okuholela ekushisweni kokuqhunyiswa kanye nokunqwabelana komli.

Inzuzo yokusebenza kwenjini ukuthi ayikhokhiswa kakhulu, okunciphisa ingozi yokwehluleka okumba eqolo futhi kube lula ukuklama. Enye inzuzo enkulu ithuba lokufaka uhlelo lwe-HBO.

Uhlobo lwakamuva lwenjini ye-Syactiv-G ifakwe uhlelo lokuvala amasilinda amabili kanye nesistimu ye-hybrid emnene, ekuvumela ukuthi ushayele injini icime ngokuphelele ngesikhathi esifushane.
