I-STRIKE ESIBINI
Igama elithi umjikelo we-stroke lithetha ukuba i-injini iphuhlisa i-im-pulse yamandla ngalo lonke ixesha ipiston isihla.I-cylinder ngokuqhelekileyo inamazibuko amabini, okanye iipaseji, enye (ebizwa ngokuba yi-intake port) ukuvuma umxube we-air-fuel, enye ukuvumela iigesi ezitshisiweyo ukuba zibaleke emoyeni.La mazibuko agqunywe kwaye atyhilwe yipiston njengoko ihla inyuka.
Xa ipiston ihambela phezulu, isithuba ebesikuyo kumzantsi we-injini iba livacuum.Umoya uyakhawuleza ukuzalisa isithuba, kodwa ngaphambi kokuba ungene, kufuneka udlule kwiatomizer ebizwa ngokuba yicarburetor,
apho ithatha amathontsi amafutha.Umoya utyhala kuvuleke intsimbi yasentlakohlaza yentsimbi phezu kwentunja ekwikhrankcase kwaye namafutha angene kwikhrankcase.
Xa ipiston isihla, ityhala zombini ngokuchasene nentonga yokudibanisa kunye ne-crankshaft, kunye nomxube wamafutha omoya ngokunjalo, ngokuyinxenye iyawucinezela.Ngexesha elithile, ipiston ityhila i-port yokungena.Eli zibuko likhokelela kwi
i-crankcase kwi-cylinder engaphezulu kwepiston, evumela umxube wamafutha omoya oxinzelelweyo kwi-crankcase ukuba ungene kwi-cylinder.
Ngoku makhe sijonge kumjikelo wamandla wokwenyani ku-1-2, siqala ngepiston kweyona ndawo isezantsi yokubetha kwe-up-and-down kwicylinder.Umxube wamafutha omoya uqukuqela ngaphakathi kwaye uqalisa ukutyhala iigesi zokukhupha ezitshileyo
khupha izibuko lokukhupha amanzi, eliye lagqunywa nalo.
I-piston iqala ukunyuka, ngaxeshanye igqibezela umsebenzi wokutyhala iigesi ezitshisiweyo zokukhupha i-exhaust port, kunye nokucinezela umxube we-fuel emoyeni kwi-cylinder.Xa ipiston ifikelela phezulu
I-cylinder, ipiston igqume amazibuko amabini, kwaye umxube we-air-fuel uxinzelelwe kakhulu.Ngeli xesha i-spark plug, efakwe kwigumbi lokutsha, ihambisa intlantsi evutha umxube.Okukhona ubuninzi boxinzelelo, amandla amakhulu ogqabhuko-dubulo, kunye noxinzelelo olukhulu lokuhla kwipiston.
I-piston inyanzeliswa phantsi kwaye idlulisela amandla ngokusebenzisa intonga yokudibanisa kwi-crankshaft, ukuyijika.I-piston ehamba ezantsi ityhila i-port yokukhupha, emva koko i-port yokungena kwaye iqala kwakhona
umsebenzi wokucinezela umxube wamafutha omoya kwikhrankcase, ukuwunyanzela ukuba uqukuqelele kumbhobho ongentla.
Nangona uninzi lweenjini zemijikelo emibini zisebenzisa ivalve yeflapper, ebizwa ngokuba yingcongolo, kwikhrankcase, ezinye iinjini azenzi.Banezibuko lesithathu, eligqunywe kwaye lityhilwe yi-fhe piston, evumela umxube wamafutha omoya ukuba ungene ngaphakathi.
akukho ndawo kwikhrankcase eyenziwe yipiston ehamba phezulu.Bona 1-3.
