Njira yogwiritsira ntchito jenereta ya dizilo yotulutsa mpweya:
Kupanikizika kwa anthu kumapeto kwa sitiroko yotopa kumakhudzana ndi 0,105 ~ 0.115 MPa, komanso kutentha kwa mpweya wotsalira wotsalira ndi pafupifupi 850-960K.Popeza mavavu olowera komanso otulutsa amatsekedwa koyambirira komanso mochedwa;kumapeto kwa chisangalalo chotulutsa mpweya komanso kuyamba kwa mpweya, pisitoni ili pafupi ndi malo apamwamba, ndipo kutsekedwa kwa mpweya kumatsegulidwa kwa nthawi.Nthawi imayimiridwa ndi ngodya ya crankshaft.
Pambuyo pa kutha kwa sitiroko kuposa, mpweya wa mpweya unayambika, kotero kuti ntchito yonseyo inabwerezedwa molingana ndi ndondomeko yomwe ili pamwambapa.Chifukwa chakuti mkombero ntchito injini dizilo anamaliza ndi 4 sitiroko pisitoni, ndiye kasinthasintha crankshaft anamaliza, amatchedwa 4 -stroke dizilo.
Mu mathamangitsidwe anayi a injini ya dizilo -stroke, ulendo wokhawo umatulutsa chilimbikitso chogwira ntchito, komanso zikwapu 3 zotsalazo ndi ntchito yokonzekera kukonzekera.
Kuti agwiritse ntchito inertia ya airflow panthawi yonseyi, mpweya wotulutsa mpweya unatulutsidwa woyera, komanso valve yotulutsa mpweya inatsekedwa pambuyo pa mapeto apamwamba.Mphepete mwa mpweya wotulutsa mpweya umasonyeza kuti panthawi yotulutsa mpweya, mphamvu ya mpweya mu silinda imakhala yosasinthika, komabe imakhala yokwera kwambiri kuposa mphamvu ya mumlengalenga.
Chifukwa cha kukana kwa dongosolo la utsi, kumayambiriro kwa chiwombankhanga cha mpweya, kupanikizika kwa mpweya mu silinda kuphatikizapo kuthamanga kwa mlengalenga kunali 0.025-0.035 MPa, komanso kutentha kwake kwa TB = 1000 mpaka 1200K.Pofuna kuchepetsa kukana kwa pisitoni panthawi yonseyi, valavu yotulutsa mpweya imatsegulidwa musanayambe kuchepetsedwa.Mwamsanga pamene shutoff yotulutsa mpweya inatsegulidwa, mpweya wokhala ndi vuto linalake linatuluka mwamsanga mu silinda, komanso kuthamanga kwa silinda kunatsika mofulumira.Mwanjira imeneyi, pisitoni ikasunthira m'mwamba, mpweya wotuluka mu chubu cha cyndrical unkawerengera pisitoni m'mwamba.
