Inqubo yokusebenza ye-diesel generator exhaust stroke:
Ingcindezi yobudlelwane bomphakathi ekupheleni kwe-exhaust stroke ihlobene no-0.105 ～ 0.115 MPa, kanye nezinga lokushisa legesi ephumayo esele licishe libe ngu-850-960K.Njengoba ama-valve okufinyelela kanye ne-exhaust avaliwe ngaphambi kwesikhathi nangemuva;ekupheleni kwenjabulo yokukhipha umoya kanye nokuqala kokungena komoya, i-piston iseduze nendawo yokumisa ephezulu, futhi i-exhaust shutoff ivuliwe isikhathi esithile.Isikhathi sima ekhoneni le-crankshaft.
Ngemuva kokuthi i-exhaust stroke ingaphezu kwalokho, ukungena komoya kwaqalwa, ngakho wonke umjikelezo womsebenzi waphindwa ngokuya ngenqubo engenhla.Ngenxa yokuthi umjikelezo wokusebenza wale injini ye-diesel usuqedile nge-4 piston strokes, okungukuthi, ukujikeleza kwe-crankshaft sekuphelile, kubizwa ngokuthi i-4 -stroke diesel motor.
Ngokujaha okune kwenjini ye-diesel ene-stroke, uhambo olusebenzayo kuphela olukhiqiza ugqozi lokusebenza, kanti futhi imivimbo emi-3 esele iyinqubo yokulungiselela edla umsebenzi.
Ukuze kusetshenziswe inertia yokugeleza komoya kuyo yonke i-exhaust, igesi yokukhipha ikhishwe ihlanzekile, kanye ne-valve yokukhipha ivalwe ngemva kwesici sokuphela esiphezulu.Ijika le-exhaust stroke liphakamisa ukuthi phakathi nenqubo yokukhipha umoya, ukucindezeleka kwegesi kusilinda cishe akushintshile, nokho kuphakeme ngandlela-thile kunokucindezela komkhathi.
Ngenxa yokumelana nesistimu yokukhipha umoya, ekuqaleni kwe-exhaust stroke, ukucindezeleka kwegesi ku-cylinder kanye nokucindezela komkhathi kwakuyi-0.025-0.035 MPa, kanye nezinga lokushisa layo le-TB = 1000 kuya ku-1200K.Ukuze wehlise ukumelana kwepiston kuyo yonke i-exhaust, i-valve yokukhipha ivuleke ngaphambi kwesici esincishisiwe.Ngokushesha nje lapho kuvulwe i-exhaust shutoff, igesi enokucindezeleka okuthile yaphuma ngokushesha esilinda, kanye nokucindezela ku-cylinder kwehla ngokushesha.Ngale ndlela, lapho i-piston isuka phezulu, igesi yokukhipha umoya eshubhuni eyi-cyndrical yayibala i-piston ibheke phezulu.
