Inkqubo yokusebenza ye-diesel generator exhaust stroke:
Uxinzelelo lobudlelwane boluntu ekupheleni kwe-exhaust stroke inento yokwenza ne-0.105 ～ 0.115 MPa, kunye nobushushu begesi eseleyo malunga ne-850-960K.Ekubeni ukufikelela kunye neevalvu zokukhupha zivaliwe kwangoko kwaye emva kwexesha;ekupheleni kwe-exhaust thrill kunye nokuqala kokungena komoya, i-piston isondele kwindawo ephezulu yokumisa, kwaye i-exhaust shutoff ivuliwe ixesha elithile.Ixesha limele kwikona yecrankshaft.
Emva kokuba i-exhaust stroke ingaphezu kwe-, i-air intake yaqalwa, ngoko ke wonke umjikelo womsebenzi waphindwa ngokwenkqubo engentla.Ngenxa yokuba umjikelo wokusebenza wale injini ye-diesel ugqitywe nge-4 piston strokes, oko kukuthi, ukujikeleza kwe-crankshaft kugqityiwe, kubizwa ngokuba yi-4 -stroke motor diesel.
Kwiingxakeko ezine ze-injini ye-diesel ezine-stroke, kuphela uhambo olusebenzayo luvelisa inkuthazo yokusebenza, kwaye kwakhona imivumbo emi-3 eseleyo yinkqubo yokulungiselela umsebenzi.
Ukuze kusetyenziswe i-inertia yokuphuma komoya kuyo yonke i-exhaust, i-gas yokukhupha ikhutshwe icocekile, kunye ne-valve yokukhupha ivaliwe emva kokuphela kwendawo ephezulu.I-curve ye-exhaust stroke ibonisa ukuba ngexesha lenkqubo yokukhupha, uxinzelelo lwegesi kwi-cylinder luphantse lungatshintshi, nangona kunjalo luphezulu kunoxinzelelo lwe-atmospheric.
Ngenxa yokuchasana kwenkqubo yokukhupha, ekuqaleni kwe-stroke yokukhupha, uxinzelelo lwegesi kwi-cylinder kunye noxinzelelo lwe-atmospheric lwaluyi-0.025-0.035 MPa, kunye nezinga layo lokushisa i-TB = 1000 ukuya kwi-1200K.Ukuze unciphise ukuchasana kwepiston kuyo yonke i-exhaust, ivalve yokukhupha ivule ngaphambi kokuba kuncitshiswe into.Ngokukhawuleza ukuba i-exhaust shutoff yavulwa, igesi enoxinzelelo oluthile ngokukhawuleza yaphuma kwi-cylinder, kunye noxinzelelo kwi-cylinder yehla ngokukhawuleza.Ngale ndlela, xa ipiston ifuduka inyuka, igesi yokukhupha kwityhubhu yecyndrical ibalwa kwipiston ukuya phezulu.
