Kushanda maitiro edhiziri jenareta exhaust sitiroko:
Kudzvinyirirwa kwehukama hweveruzhinji pakupera kweanopopota sitiroko ine chekuita ne0.105 ～ 0.115 MPa, uye zvakare tembiricha yeasara gasi rekupedza simba rinenge 850-960K.Sezvo mavharuvhu ekupinda pamwe neanopedza simba akavharwa nekukurumidza uye kunonoka;pakupera kwekunakidzwa kwekupedza uye kutanga kwemhepo yekupinda, piston iri pedyo nenzvimbo yepamusoro yekumira, uye kuvhara kwemhepo kunovhurwa kwenguva yakati.Nguva inomiririrwa nekona ye crankshaft.
Mushure mekupera kwekurohwa kwakawanda kupfuura, kutorwa kwemhepo kwakatangwa, saka basa rose rebasa rakadzokororwa maererano nemaitiro ari pamusoro apa.Nekuda kwekuti kutenderera kwekushanda kweinjini yedhiziri kunopedzwa ne4 piston sitiroko, ndiko kuti, crankshaft kutenderera kwapera, inonzi 4 -stroke diesel mota.
Mukumhanya mana kwechina-stroke injini yedhiziri, rwendo rwekushanda chete runoburitsa kurudziro yekushanda, uyezve matsiro matatu asara ibasa-rinopedza gadziriro yekugadzirira.
Kuti ushandise iyo inertia yekuyerera kwemhepo mukati mekupera, gasi rekuburitsa rakaburitswa rakachena, pamwe nevhavhavhavha yakavharwa mushure meiyo yekupedzisira chinhu.Iyo exhaust stroke curve inoratidza kuti panguva yekupedza, kushushikana kwegasi mucylinder kunenge kusachinjika, zvisinei kuti kwakati kwakakwira kupfuura kumanikidzwa kwemhepo.
Nekuda kwekupikiswa kweiyo exhaust system, pakutanga kweiyo exhaust sitiroko, kushushikana kwegasi mucylinder pamwe nemhepo yemhepo yaive 0.025-0.035 MPa, uye zvakare tembiricha yayo TB = 1000 kusvika 1200K.Kuti uderedze kushorwa kwepiston mukati mekupera simba, vheji yekuburitsa yakavhurwa pamberi pechinhu chakaderedzwa.Nenguva isipi kuvharwa kwemhepo yakavhurwa, gasi rine kushushikana kwakakurumidza kubuda kubva muhumburumbira, pamwe nekumanikidza mu cylinder kwakadonha nekukurumidza.Nenzira iyi, apo piston yakasimuka kumusoro-wadhi, gasi rekuburitsa mucyndrical chubhu yakaverengerwa papiston kumusoro.
