Phonononga uPhuhliso lweNkqubo yokuFumana iGenereyitha yeDizili

I-1, i-Cummins generator iseti inkqubo yokungenisa umoya yoxinzelelo

I-Turbocharging yicompressor yomoya esebenzisa amafu erhasi ephumayo esuka kwinjini yokutsha yangaphakathi ukuyiqhuba.Isixhobo se-supercharging sinokuphucula ukuhamba kobunzima bomoya kwi-cylinder ngokucinezela umoya ofunekayo ukutsha kwepetroli phantsi kwemeko yomthamo ofanayo wokusebenza kunye nesantya sombane. ijenereyitha yedizili , kwaye emva koko uphucule ukuxinana kwamandla ejeneretha ye-diesel.Ukubunjwa kwenkqubo ye-supercharger ayibandakanyi kuphela umzimba we-supercharger, i-intercooler, i-supercharger yokupholisa i-hardware ye-hardware, kodwa iquka inzwa yoxinzelelo lwe-supercharger, imitha yokuhamba komoya, inzwa yesantya, inzwa yokuqhawula, i-injector ye-fuel, i-coil yokutshisa kunye nezinye izinzwa ze-elektroniki zomqondiso. impendulo.Umzimba ophambili weTurbocharger uquka ivalve yokuphuma enxaxhileyo kunye nevalve yokunceda i-inlet pressure, isignali ye-electronic sensor feedback, njengenkqubo ye-EMS ngokusebenzisa isigwebo sesantya somqhubi wemfuno yamandla ejenereyitha yedizili, ukuze kuphume ubungakanani bomsebenzi woxinzelelo, lawula umxholo we-supercharger wokugqitha. ukuvulwa kwevalvu, ukuze umbhobho omninzi kwicala le-injini yokuphuma, yandise uxinzelelo, yenza uxinzelelo lokungena ukufikelela kwiinjongo, Yandisa amandla ejenereyitha yedizili.Xa i-EMS ifumana isithuthi kwi-sensor nganye ye-elektroniki ayifuni ukunyusa amandla, ngeli xesha i-EMS imveliso ye-pressurized duty ratio yi-0, i-exhaust ukusuka kwi-pipeline discharge, i-supercharger ayisekho uxinzelelo ekungeneni;I-EMS iphinda ilawule ukuvulwa kwe-valve yokunciphisa uxinzelelo kwi-supercharger ukunciphisa ngokukhawuleza uxinzelelo lokungena kwinqanaba elingenaxinzelelo kunye nombane we-diesel generator kumandla ekujoliswe kuwo.Iimpawu zendalo ze-supercharger zimisela ubuninzi be-supercharger enkulu.Iimpawu zendalo ze-supercharger ziquka isantya esiphezulu esivunyelwe yi-supercharger kunye nomgca wokunyuka kwe-supercharger.Xa uhlobo oluthile lwe-supercharger lukhethwa kwi-generator ye-diesel, iimpawu zendalo zenkqubo ye-supercharger zichongwa.Ngokwesantya esiphezulu esivumelekileyo se-turbocharger kunye nomgca wokunyuka we-turbocharger, umlinganiselo ophezulu we-turbocharging kwisantya ngasinye samandla ulungelelaniswa nokulinganisa ibhentshi ye-diesel generator.Emva kokulungelelaniswa kwejenereyitha ye-diesel, ulwalathiso lolawulo olusisiseko lwe-turbocharger luye lwamiselwa.

2, Cummins   Iseti yejenereyitha isixokelelwano sexesha levalvu eguquguqukayo

Xa isantya kunye nomthwalo wejenereyitha ye-diesel itshintsha, umthamo wokungena, umthamo wokukhupha, i-inlet kunye ne-exhaust flow velocity, ixesha lokungena kunye nokukhupha i-stroke, inkqubo yokutsha kwi-cylinder iyahluka, kwaye iimfuno zesigaba se-valve kunye nokuphakanyiswa kwe-valve ziyahluka. kwakhona ezahlukeneyo.Umzekelo: xa isantya siphezulu, isantya sokungena siphezulu kwaye amandla e-inertia makhulu, ngoko ke kuthenjwa ukuba ivalve yokungena iya kuvulwa kwangaphambili kwaye ivalwe kamva, ukuze kusetyenziswe ngokupheleleyo inertia yokungena. ukuhamba kwaye uhlawule umoya omtsha kwi-cylinder kangangoko kunokwenzeka;Ngokuchasene noko, xa isantya se-diesel generator siphantsi, izinga lokungena kwe-inlet liphantsi, kwaye amandla e-inertia amancinci.Ukuba ivalve yokungena kade yokuvala iAngile inkulu kakhulu, irhasi entsha ethe yangena kwicylinder iyakucudiswa ngaphandle kwecylinder ngepiston enyukayo kwi-compression stroke.Ngokufanayo, ukuba i-valve yokungena ivulwe kwangaphambili, ngenxa yokuba i-piston inyuka i-exhaust, kulula ukucinezela igesi yokukhupha kwipayipi yokungena, ukwenzela ukuba i-gesi eseleyo ephumayo kwi-intake inyuke, kodwa igesi entsha iyancitshiswa, ngoko ke. ukuba ijenereyitha yedizili ayizinzanga.Ngenxa yoko, akukho lungiselelo lwesigaba sevalve esisigxina esibonelela ngokusebenza ngokufanelekileyo kwiijeneretha zedizili kuzo zombini isantya esiphezulu nesisezantsi.Inkqubo ye-valve ye-valve eguquguqukayo (i-VVT) inokuphucula uqoqosho lwamafutha, ukusebenza kwamandla kunye nokuzinza kokusebenza kweejeneretha ze-diesel phantsi kwezantya ezahlukeneyo kunye nemithwalo ngokuguqula isigaba sokusasazwa kweejeneretha ze-diesel, kunye nokunciphisa ukungcola okuphumayo.

I-3, i-Cummins generator iseti iteknoloji yevalvu ye-elektroniki

Iijenereyitha zedizili ngesantya esahlukileyo.Iimfuno zokuhamba kweevalvu ziyahluka kakhulu.Ngesantya esiphantsi, ngenxa yokuba umthamo wokungena uncinci, ukuba i-valve yokuhamba inkulu, ayiyi kukwazi ukuvelisa uxinzelelo olubi lokungena, i-injector ayikwazi ukuxutywa ngokupheleleyo nomoya ophefumlelweyo emva kwenaliti, okukhokelela ekusebenzeni okuphantsi kokutsha, I-torque enesantya esiphantsi iya kuncitshiswa kakhulu, kwaye nokukhutshwayo kuya kwanda.Kule meko, kufuneka kusetyenziswe i-valve encinci.Ngenxa yokuhamba kwevalve encinci, uxinzelelo olubi lokuthatha luyanda, kwaye inani elikhulu lee-vortices ezibangelwayo linokuxuba ngokupheleleyo umxube ukuhlangabezana nokusebenza okuqhelekileyo kwejeneretha ye-diesel ngesantya esiphantsi.Ngesantya esiphezulu, imeko ichasene.Ngeli xesha, umthamo wokuthatha ukhulu kakhulu.Ukuba i-valve yokuhamba incinci kakhulu, ukuchasana kokuthatha kuya kuba kukhulu kakhulu ukukhupha umoya owaneleyo, ngaloo ndlela kuchaphazela ukusebenza kwamandla.Ke ngoko, ngesantya esiphezulu, kuyafuneka ukuba uhambe ngevalvu enkulu, ukuze ufumane eyona mfuno ilungileyo yevalvu.Ukunciphisa ukusetyenziswa kwamafutha, indlela yevalvu ehlengahlengiswayo ye-BMW ilawula ubungakanani bomoya kwijenereyitha yedizili hayi nge-throttle kodwa ngokunyuswa okuhlengahlengiswayo kwevalve yokungena.Ngokusetyenziswa kweshafti ye-eccentric ehlengahlengiswa ngombane, isenzo secamshaft kwivalve yevalve yoxinzelelo lwentonga sitshintshwa sisileve esiphakathi, ngaloo ndlela sivelisa ukunyuswa kwevalve yokungena elungelelanisiweyo.I-throttle isetyenziswe kuphela ngexesha lokuqala kunye nokusebenza ngokukhawuleza.Kuzo zonke ezinye iimeko zokusebenza i-throttle ivuleke ngokupheleleyo kunye ne-throttling encinci.Itekhnoloji yevalvu ye-elektroniki ifezekisa eyona ntsalela ilungileyo yetorque yamandla ephuma kwijenereyitha yedizili phantsi kweemeko ezahlukeneyo zesantya ngohlengahlengiso olungena nyathelo lokubetha kwevalve.

Inkqubela phambili eqhubekayo yoluntu lwanamhlanje ikwabangele imiphumo emibi emininzi kwimekobume esihlala kuyo.Kwimeko enjalo, phantsi kweempembelelo zophuhliso lwexesha elizayo lwenzululwazi kunye nobuchwepheshe iseti evelisa ikhabhoni ephantsi, ukonga amandla, uphuhliso lokhuselo lokusingqongileyo iye ngokuthe ngcembe ibe ngumkhwa, uphuhliso lwenkqubo yokungenisa idizili yophando lwenkqubo yokungenisa umoya, hayi kuphela uncedo. siphinde siqonde uphuhliso oluqhelekileyo lwenkqubo yokungenisa umoya we-diesel generator, kwakhona kwisifundo sexesha elizayo sokuhlola inkqubo yokungenisa umoya we-generator kudlala indima ekhokelayo, Ukungalungi kokusetyenziswa kwamafutha aphezulu kunye nezinga eliphezulu lokungcoliseka kweesethi zejeneretha zingasombululwa ngesinyathelo ngesinyathelo.
