Nekukurumidza kuvandudzwa kwemotokari dzemagetsi matsva, injini dzinopisa dzemukati dziri kuswedera pedyo nekubviswa. Mota dzeHybrid uye mota dzemagetsi dzine zvimwe zvakanakira kuderedza kuburitswa nekudzikisa mari yekushandisa. Pamusoro pemotokari dzemagetsi dzakachena, injini dzichiri kuita basa rakakosha mu plug-in hybrid uye mota dzakareba.
Subaru yakanyorera patent nyowani yeimwe inoshanda pre-combustion system. Porsche parizvino iri kuongorora masisitimu akadaro kuti awedzere simba. Zvisinei, Subaru haisi kutarisa simba pachayo, asi kubudirira. Iyo patent inonyanya kugadzirisa dambudziko rekutonhora kutanga kwejini.
Sezvatinoziva tese, kuitira kuti iyo nzira nhatu-inoshandura inoshandura nekukurumidza kugadzirisa kubuda kwemhepo panguva yekutonhora kwekutanga, kumhanya kweinjini kuchakwira kupfuura hafu yekumhanya kwakajairika, uye kunowanzo chengetwa pakati pe1500 ne1800 rpm. Mukuwedzera, apo injini inongoerekana yaderera panguva yekufambisa kwakajairika, mafuta haakwanisi kupiswa zvakakwana uye anonamatira kumadziro ekamuri rinopisa. Mamiriro aya anozowedzera kuwanda kwemafuta uye kuita kuti injini yekupisa ibudise mamwe mahydrocarboni anokuvadza. Iyo pre-combustion patent inoshandiswa neSubaru inzira yekugadzirisa dambudziko remarara emafuta uye kuwedzera kuburitsa panguva yekutonhora kwechinyakare.
Pre-combustion haisi tekinoroji nyowani, asi haiwanzo kushandiswa mumotokari dzemazuva ese. Nokuti, kunyange ikashandiswa, hazvizivikanwi zvikuru nevoruzhinji. Muchinyakare mukati meinjini yekupisa, musanganiswa wemhepo-mafuta unowanikwa nejekiseni uye vharafu yekupinza inobatidzwa mukamuri huru yekupisa ne spark plug. Pre-combustion tekinoroji inoshandisa hemispherical shell yakatenderedza spark plug kuti igadzire yakasarudzika kamuri yekupisa umo pre-kupisa kunogona kuitika.
Iyo pre-combustion system inoshandisa diki mudziyo wekubatidza mune imwe kamuri yekupisa yekudzima moto uye wobva wabatidza mafuta mukamuri huru yekupisa. Iyi alternate ignition system inogonesa kunaka kwekupisa, ichibvumira kutenderera kweinjini uye kuderedza marara, kunyanya panguva yekutonhora kunotanga apo mamwe mafuta anopiswa zvishoma nezvishoma. Iyo pre-combustion chamber ine yepakati/hombe yekuvhura uye maviri madiki kuburikidza nemakomba kumativi ese, kuvhura uye kuburikidza nemakomba akarongwa kuti atungamire mhepo kubva pre-kupisa chamber yakasarudzwa yepamusoro-pressure air valve, pamwe nekutungamira spark inobatidza mafuta.

Ivhavha yemhepo inopa mhepo kune pre-chamber inoita senhovo panguva yekutanga, yakakomberedza pre-chamber ine mhepo yemhepo, kudzivirira musanganiswa wemafuta kubva pakunamatira kune kunze kwekamuri yepamberi, uyewo uchifambisa kupisa kwakanyatsonaka kwemafuta / musanganiswa wemhepo mukati me pre-chamber. Panguva yekutanga, jekiseni remhepo rinotanga kushandiswa, rinoteverwa nejekitori remafuta, richigadzira "swirl" mhedzisiro mukati mekamuri yekupisa, nemajekiseni maviri anopindirana mukufamba kwenguva.
Iyo tekinoroji haiunze injini dzinopisa mukati kumazinga ehubridbe kana mota dzemagetsi, asi zvinogona kutungamira kune mamwe magadzirirwo epasi.
