Injini Yomjikelezo We-Atkinson
Injini yomjikelezo we-Atkinson iyinjini evuthayo yangaphakathi. Yaklanywa nguJames Atkinson ngo-1882. Ingqikithi yenjini iwukuthola ukusebenza kahle okuphezulu komlilo, okungukuthi, ukusetshenziswa kancane kukaphethiloli.
Lolu hlobo lokuvutha luyahluka kumjikelezo we-Otto ovamile ngokuvuleka isikhathi eside kwevalvu yokumunca, edlulela esigabeni sokuminyanisa lapho ipiston iphakama futhi icindezela ingxube. Lokhu kuholela eqinisweni lokuthi ingxenye yengxube eseyimuncwa kakade iphushwa iphume kusilinda ibuyele epayipini lokumunca. Kuphela ngemva kwalokhu lapho i-valve yokungenisa ivala, okungukuthi, ngemva kokuba ingxube kaphethiloli imuncwa, ilandelwa "ukukhishwa" okuthile bese kuphela ukucindezela okuvamile. Injini iziphatha sengathi inokususwa okuncane ngenxa yokuthi izilinganiso zokucindezelwa nokunwetshwa zihlukile. Ukuvulwa okuqhubekayo kwe-valve yokumunca kunciphisa isilinganiso sangempela sokucindezela. Njengoba sekushiwo kakade, leli fomu lomlilo livumela isilinganiso sokunweba ukuba sibe phezulu kunesilinganiso sokucindezela ngenkathi sigcina ingcindezi evamile yokucindezela. Le nqubo inenzuzo ekusebenzeni kahle komlilo ngoba isilinganiso sokucindezela ezinjinini zikaphethiloli sinqunyelwe isilinganiso se-octane sikaphethiloli osetshenzisiwe, kuyilapho isilinganiso esiphezulu sokunwetshwa sivumela izikhathi zokunweba ezinde (isikhathi sokushiswa) futhi ngaleyo ndlela kunciphisa izinga lokushisa legesi yokukhipha umoya - ukusebenza kahle kwenjini ephezulu. . Eqinisweni, ukusebenza kahle kwenjini kuholela ekwehleni kokusetshenziswa kukaphethiloli ngo-10-15%. Lokhu kufezwa ngomsebenzi omncane odingekayo ukuze ucindezele ingxube, kanye nokulahlekelwa okuphansi kokumpompa kanye ne-exhaust, kanye nesilinganiso sokucindezela esiphezulu esishiwo ngenhla. Ngokuphambene nalokho, ubungozi obuyinhloko benjini yomjikelezo we-Atkinson amandla aphansi ngamalitha, anxeshezelwa ngokusetshenziswa kwemoto kagesi (i-hybrid drive) noma injini yengezwe yi-turbocharger (umjikelezo weMiller), njengaseMazda. I-Xedos 9 enenjini. injini 2,3 l.
