Izinjini ze-LF class zingamayunithi esimanje esizukulwane esisha anamandla athuthukisiwe kanye nokulungiseka. Idivayisi inomthamo osebenzayo we-1,8 l, amandla amakhulu - 104 kW (141 hp), i-torque ephezulu - 181 Nm / 4100 min.-1. Injini ikuvumela ukuthi ufinyelele isivinini esiphezulu esingu-208 km/h.
Izici ezinamandla zenjini ye-Mazda LF emdwebeni
Izinjini zingafakwa nge-S-VT - Sequential Valve Timing turbocharger. I-turbocharger isebenza ngomgomo wokusebenza kumandla wegesi ephumayo eshisiwe. Idizayini yayo ihlanganisa amasondo e-axial blade amabili, aphothwa kusetshenziswa igesi eshisayo engena emzimbeni wengxenye. Isondo lokuqala, isondo elisebenzayo, lijikeleza ngesivinini esingu-100 min -1. Ngosizo lwe-shaft, isondo lesibili le-blade nalo liyajikeleza, liphonsa umoya ku-compressor. Ngakho-ke, umoya oshisayo ungena ekamelweni elivuthayo, ngemva kwalokho upholisa nge-radiator yomoya. Ngenxa yalezi zinqubo, ukwanda okukhulu kwamandla enjini kufinyelelwa.
Inkampani ye-Mazda yakhiqiza izinjini zalolu chungechunge kusukela ngo-2007 kuya ku-2012, futhi ngalesi sikhathi yakwazi ukwenza ukuthuthukiswa okuningi kwezobuchwepheshe, kokubili ekwakhiweni kweyunithi nasezintweni zayo zobuchwepheshe. Ezinye izinjini zithole izindlela ezintsha zokubeka isikhathi se-valve. Amamodeli amasha afakwe ama-cylinder blocks enziwe nge-aluminium. Lokhu kwenziwa ukuze kwehliswe isisindo semoto sisonke.

Ingaphambili lenjini lifakwe isembozo esinembobo yokulungiswa okuthuthukisiwe. Lokhu kwenza kube lula ukuvula i-ratchet yokulungisa iketango kanye nokukhiya ingalo eqinile. Amasilinda amane enjini ahlelwe ngomugqa owodwa. Kusukela ngezansi, iyunithi imbozwe nge-sump, eyenza i-crankcase. Ngesikhathi esifanayo, le ngxenye iyisitsha esiqukethe uwoyela, lapho inkimbinkimbi yezingxenye zenjini igcotshwa, ivikelwe futhi ipholile, ngaleyo ndlela ivikele ekugugeni.

Izibuyekezo zomsebenzisi wenjini
UViktor Fedorovich, oneminyaka engu-57 ubudala, imoto ye-Mazda 3, injini ye-LF: ulethe imoto yezemidlalo yaseMazda esetshenzisiwe. Imoto ihambe amakhilomitha angaphezu kuka-170. Kwadingeka ngishintshe uhlelo lokunikezwa kukawoyela + ukulungisa iyunithi esiteshini sesevisi. Injini ilungiseka kahle. Sekukonke ngijabule ngakho konke, into esemqoka ukusebenzisa kuphela amafutha angcono kakhulu kanye nophethiloli.
