OKUBILI
Igama elithi umjikelezo we-two-stroke lisho ukuthi injini ikhiqiza amandla ashukumisayo ngaso sonke isikhathi lapho ipiston yehla.I-cylinder ngokuvamile inamachweba amabili, noma amaphaseji, eyodwa (ebizwa ngokuthi i-intake port) yokwamukela ingxube yamafutha omoya, enye ukuvumela amagesi ashisiwe ukuba abalekele emkhathini.Lezi zikhumulo zimbozwe futhi zembulwe yi-piston njengoba ihamba phezulu naphansi.
Lapho i-piston ihambela phezulu, indawo ebikuyo engxenyeni engezansi yebhulokhi yenjini iba indawo engenalutho.Umoya ugijima uvala isikhala, kodwa ngaphambi kokuthi ungene, kufanele udlule ku-atomizer ebizwa ngokuthi i-carburetor,
lapho icosha khona amaconsi kaphethiloli.Umoya uphusha i-spring metal flapper phezu kwembobo ku-crankcase futhi ngophethiloli ungene ku-crankcase.
Lapho i-piston yehla, iphusha kokubili ku-rod yokuxhuma kanye ne-crankshaft, kanye nengxube yamafutha omoya kanye, ngokuyicindezela ngokwengxenye.Esikhathini esithile, i-piston ivula imbobo yokungena.Lesi sikhumulo sisuka e-
i-crankcase kusilinda ngenhla kwepiston, okuvumela ingxube yamafutha omoya ecindezelwe ku-crankcase ukuthi igelezele kusilinda.
Manje ake sibheke umjikelezo wamandla wangempela ku-1-2, siqala ngepiston engxenyeni ephansi kakhulu yokushaywa kwayo phezulu naphansi kusilinda.Ingxube kaphethiloli womoya igeleza futhi iqala ukuphusha amagesi aphumayo ashile
ngaphandle kwe-exhaust port, nayo engamboziwe.
I-piston iqala ukuya phezulu, ngesikhathi esifanayo iqedela umsebenzi wokuphusha amagesi e-exhaust ashile ngaphandle kwe-exhaust port, futhi icindezela ingxube yamafutha omoya kusilinda.Lapho i-piston ifinyelela phezulu
Isilinda, ipiston imboze amachweba amabili, futhi ingxube yamafutha omoya icindezelwe kakhulu.Kuleli qophelo i-spark plug, exhunywe egumbini elivuthayo, iletha inhlansi ethungela ingxube.Lapho inani lokucindezelwa likhulu, amandla amakhulu okuqhuma, kanye nokucindezela okuya phansi kwepiston.
I-piston iphoqeleka phansi futhi idlulisela amandla ngenduku yokuxhuma ku-crankshaft, iyiphendule.I-piston eya phansi iphinde yembule imbobo yokukhipha umoya, bese imbobo yokungena bese iqala futhi
umsebenzi wokucindezela ingxube yamafutha omoya ku-crankcase, ukuyiphoqa ukuthi igeleze kusilinda ngaphezulu.
Nakuba izinjini eziningi ezinemijikelezo emibili zisebenzisa i-valve ye-flapper, ebizwa ngokuthi umhlanga, ku-crankcase, ezinye izinjini azikwenzi.Banechweba lesithathu, elimbozwe futhi lembulwe i-fhe piston, elivumela ingxube yamafutha omoya ukuthi igelezele
ingenalutho ku-crankcase edalwe ipiston ehamba phezulu.Bheka 1-3.
