Si zachilendo kuti chitoliro chotulutsa mpweya chimveke bwino injini ikatha.Chitoliro chotulutsa mpweya chimakhala chotentha kwambiri injini ikugwira ntchito ndipo imakula ikatenthedwa.Phokosoli lidzayamba pamene kutentha kwachepa injini itatsekedwa.Ngati pali mpweya wochepa wa carbon mu chitoliro chotulutsa galimoto yatsopano, phokoso lidzakhala lomveka bwino komanso lodziwika bwino, lomwe ndi lachilendo.

Njinga yamoto, galimoto yamawilo awiri kapena atatu yoyendetsedwa ndi injini yamafuta ndikuwongoleredwa ndi chogwirira, ndiyopepuka, yosinthika komanso yachangu.Amagwiritsidwa ntchito kwambiri polondera, zonyamula anthu ndi zonyamula katundu, komanso zida zamasewera.

Tengani mfundo yogwirira ntchito ya injini zinayi za sitiroko ndi injini ya sitiroko ziwiri monga chitsanzo: injini zinayi za sitiroko zimagwiritsidwa ntchito kwambiri.Injini ya sitiroko inayi imatanthawuza kuti silinda imayatsa kamodzi pamayendedwe anayi aliwonse obwerezabwereza a pisitoni.Mfundo yeniyeni yogwirira ntchito ndi iyi:

Kulowa: Panthawiyi, valavu yolowetsa imatsegulidwa, pisitoni imasunthira pansi, ndipo kusakaniza kwa mafuta ndi mpweya kumalowetsedwa mu silinda.

Kuponderezana: panthawiyi, valve yolowera ndi valavu yotulutsa mpweya imatsekedwa nthawi yomweyo, pisitoni ikukwera mmwamba, ndipo kusakaniza kumakanizidwa.

Kuyaka: pamene chosakaniziracho chapanikizidwa pang'ono, pulagi ya spark imalumpha ndikuyatsa mpweya wosakanikirana, ndipo mphamvu yopangidwa ndi kuyaka imakankhira pisitoni pansi ndikuyendetsa crankshaft kuti izungulira.

Kutulutsa: Pamene pisitoni imatsikira pansi kwambiri, valve yotulutsa mpweya imatsegulidwa, ndipo mpweya wotulutsa mpweya umatulutsidwa.Pistoni ikupitirizabe kutulutsa mpweya wochuluka.

Mfundo yogwirira ntchito ya injini yamitundu iwiri ndi yakuti pisitoni imayenda mmwamba ndi pansi kwa mikwingwirima iwiri ndipo spark plug imayaka kamodzi.Njira yamadyedwe a injini yachiwiri ya sitiroko ndiyosiyana kwambiri ndi injini yachinayi ya sitiroko.Injini yokhala ndi mikwingwirima iwiri imayenera kupanikizidwa kawiri.Pa injini yachiwiri ya sitiroko, kusakaniza kumalowa mu crankcase poyamba ndiyeno mu silinda.Mwachindunji, izo zimayenda mu kuyaka chipinda, pamene osakaniza wachinayi sitiroko injini umayenda molunjika mu yamphamvu.Crankcase ya injini yachinai ya sitiroko imagwiritsidwa ntchito posungira mafuta, Monga crankcase ya injini yamitundu iwiri imagwiritsidwa ntchito kusungira gasi wosakanizidwa ndipo sangathe kusunga mafuta, mafuta omwe amagwiritsidwa ntchito pa injini ya sitiroko ziwiri ndi mafuta oyaka osasinthika.

Njira yogwirira ntchito ya injini yachiwiri ya sitiroko ndi motere:

Pistoni imayenda m'mwamba ndipo mpweya wosakanikirana umalowa mu crankcase.

Pistoni imatsika kuti ipereke mpweya wosakanikirana kuchipinda choyaka moto, ndikumaliza kukanikiza koyamba.

Chisakanizocho chikafika pa silinda, pisitoni imakwera ndikutseka polowera ndi potuluka.Pamene pisitoni ikanikiza mpweya kuti ukhale wocheperako (uku ndi kukanikiza kwachiwiri), spark plug imayaka.

Mphamvu yoyaka imakankhira pisitoni pansi.Pistoni ikatsika pamalo enaake, doko lotulutsa mpweya limatsegulidwa poyamba, ndipo mpweya wotulutsa mpweya umatulutsidwa ndiyeno cholowera mpweya chimatsegulidwa.Mpweya watsopano wosakanikirana umalowa mu silinda kuti utulutse mpweya wotsalira wotsalira.
