Mazda's adventures ane jekiseni rakananga yakatanga kare kare kupfuura kuiswa kweSkyactiv series injini, uye vakaedza zvikuru. Chiitiko chakashanduka kuita injini inozvibata yakashinga inopesana nevakwikwidzi vane turbocharged nanhasi.

Mazda peturu yakananga jekiseni yakatanga kuoneka muna 2005 (2.3 DISI injini) muModel 6. Chizvarwa chechipiri Mazda 6 inoshandisa 2.0 DISI unit (uyewo muMazda 3), uye injini yeSyactiv-G yakatanga muMazda CX5 muna 2011. uye yakawanawo kushanda kwayo muchizvarwa chechitatu Mazda 6.

Iyo unit yakakwira tekinoroji, uye, kunyangwe kushomeka kwekuwedzera, ine zvigadziriso senge yakakwira compression ratio (14: 1), iyo inokubvumira kushanda paAtkinson-Miller kutenderera, kusiyanisa nguva yevharuvhu kana dhizaini yakareruka, kunyangwe iyo nguva yekutyaira inofambiswa neketani. Kune zvakare yekutanga-yekumisa system uye i-ELOOP system inodzoreredza simba rekukurumidza basa. Kiyi yekubudirira, i.e. kuchengetedza iyo chaiyo emission level, iko kutonga chaiko kwekupisa kwemusanganiswa. Motor inokura kubva pa120 kusvika ku165 hp, saka, inopa maitiro akanaka ekirasi iyi yemotokari, kunyange zvazvo inonyatsotsauka kubva ku "turbo standards" yevakwikwidzi.

Mechanically, injini haigone kuve yakaremara. Durable, hapana matambudziko nemafuta, uye Time cheni 200 zviuru. km inongoda kuongororwa, haiwanzo kuchinjwa. Carbon dema inongowanikwa mumainjini ane oiri anosandurwa zvisingaite. (max. ose 15 km) kana mushure mekushandisa mafuta ane viscosity isiriyo (inokurudzirwa 0W-20, 5W- inobvumirwa). Vashandisi vainetseka zvakanyanya nehardware.

Exhaust system inodonhedza uye yakakuvadzwa yekuyerera mita ndizvo zvinonyanya kukonzera injini kutanga kana cranking matambudziko. Kunyanya kashoma, iyo blower valve inokuvadzwa, iyo inofuridza mafuta mumakamuri ekupisa, izvo zvinotungamira mukupisa kwe detonation uye kuunganidza soot.

Kubatsira kwekushandisa kweinjini kusavapo kwe supercharging, iyo inoderedza njodzi yekutadza kunodhura uye inorerutsa dhizaini. Imwe mukana mukuru ndeye mukana wekuisa HBO system.

Iyo yazvino mhando yeSyactiv-G injini ine maviri-cylinder deactivation system uye yakapfava hybrid system, iyo inokutendera iwe kutyaira neinjini ichidzima zvachose munguva pfupi.
