Hlola Ukuthuthukiswa Kwesistimu Yokuthatha Ijeneretha Yedizili

I-1, i-Cummins generator isetha uhlelo lokungena komoya olucindezelwe

I-Turbocharging iyi-compressor yomoya esebenzisa amafu e-exhaust gas esuka enjini evuthayo yangaphakathi ukuyishayela.Idivayisi yokushaja kakhulu ingathuthukisa ukugeleza kwenqwaba yomoya kusilinda ngokucindezela umoya odingekayo ukuze kushiswe uphethiloli ngaphansi kwesimo sevolumu efanayo yokusebenza kanye nesivinini generator diesel , bese uthuthukisa ukuminyana kwamandla wejeneretha yedizili.Ukwakhiwa kwesistimu ye-supercharger akuhlanganisi umzimba we-supercharger kuphela, i-intercooler, i-supercharger cooling pipeline hardware body, kodwa futhi ihlanganisa inzwa yokucindezela kwe-supercharger, imitha yokugeleza komoya, inzwa yesivinini, inzwa yokuqhunyiswa, i-fuel injector, i-coil ignition nezinye izinzwa zikagesi zesignali. impendulo.Umzimba oyinhloko we-Turbocharger uhlanganisa i-valve yokukhipha i-bypass kanye ne-valve yokukhulula i-inlet pressure, isignali yempendulo yenzwa ye-electronic, njengesistimu ye-EMS ngokusebenzisa isidingo somqhubi wokwahlulela ngesivinini samandla ejeneretha yedizili, ukuze kukhishwe isilinganiso somsebenzi we-pressurization, ukulawula isihloko se-supercharger sokudlula i-exhaust bypass. ukuvulwa kwe-valve, ukuze kukhishwe ngaphezulu ohlangothini lwe-turbine yokukhipha amandla, kwandise ingcindezi, yenze ingcindezi yokungena ukuze ufinyelele imigomo, Khulisa amandla ejeneretha yedizili.Lapho i-EMS ithola imoto kusuka kunzwa ngayinye ye-elekthronikhi ayidingi ukukhulisa amandla, ngalesi sikhathi isilinganiso se-EMS se-pressurized duty ratio singu-0, ukuphuma kokukhishwa kwepayipi le-bypass, i-supercharger ayisacindezelwe ekuthatheni;I-EMS iphinde ilawule ukuvulwa kwe-valve yokunciphisa ingcindezi yokungenisa ku-supercharger ukuze kuncishiswe ngokushesha ingcindezi yokungena ezingeni elingacindezelwe kanye namandla ejeneretha yedizili emandleni okuhlosiwe.Izici zemvelo ze-supercharger zinquma ubukhulu beshaja enkulu.Izici zemvelo ze-supercharger zihlanganisa isivinini esiphezulu esivunyelwe i-supercharger kanye nomugqa wokuhlinza we-supercharger.Lapho uhlobo oluthile lwe-supercharger lukhethelwa umshini wokuphehla udizili, izici ezingokwemvelo zesistimu ye-supercharger ziyanqunywa.Ngokuya ngesivinini esiphezulu esivumelekile se-turbocharger kanye nolayini wokuhlinza we-turbocharger, isilinganiso esiphezulu sokushaja kwe-turbo kusivinini samandla ngasinye siyalinganiswa ukuze kulinganiswe ibhentshi le-generator diesel.Ngemuva kokulinganiswa kwejeneretha yedizili, indlela eyisisekelo yokulawula ye-turbocharger isinqunyiwe.

2, Ama-Cummins   I-generator isethi yesistimu yesikhathi se-valve eguquguqukayo

Lapho ijubane nomthwalo wejeneretha yedizili ishintsha, umthamo owuthathayo, ivolumu yokukhipha, isivinini sokugeleza kwe-inlet kanye ne-exhaust, isikhathi sokushaywa kwe-exhaust, inqubo yokuvutha kusilinda zihlukile, kanye nezidingo zesigaba se-valve nokuphakanyiswa kwe-valve ziyehluka. futhi ezahlukene.Isibonelo: uma isivinini siphezulu, isivinini sokugeleza kwe-inlet siphezulu futhi amandla e-inertia makhulu, ngakho-ke kuthenjwa ukuthi i-valve yokungena izovulwa ngaphambi kwesikhathi futhi ivalwe kamuva, ukuze kusetshenziswe ngokugcwele inertia yokungena. geleza futhi ushaje umoya omusha ku-cylinder ngangokunokwenzeka;Ngokuphambene nalokho, lapho ijubane le-generator diesel liphansi, izinga lokugeleza kwe-inlet liphansi, futhi amandla e-inertia amancane.Uma i-engeli yokuvala yokungena sekwephuzile inkulu kakhulu, igesi entsha engene kusilinda izokhanywa iphume kusilinda ngepiston ebheke phezulu ekucindezelekeni.Ngokufanayo, uma i-valve yokungena ivulwa kusenesikhathi kakhulu, ngoba i-piston ikhuphuka ngokukhipha umoya, kulula ukucindezela igesi yokukhipha epayipini lokungenisa, ukuze igesi ephumayo esele ekungeneni ikhule, kodwa igesi elisha liyancipha, ngakho-ke. ukuthi ijeneretha yedizili ayizinzile.Ngenxa yalokho, asikho isilungiselelo sesigaba se-valve esingaguquki esinikeza ukusebenza kahle kwamajeneretha edizili kokubili ngesivinini esiphezulu nesiphansi.Uhlelo lwe-variable valve timing (VVT) lungathuthukisa ukonga kukaphethiloli, ukusebenza kwamandla kanye nokuzinza kokusebenza kwamajeneretha edizili ngaphansi kwesivinini nomthwalo ohlukahlukene ngokushintsha isigaba sokusatshalaliswa kwamajeneretha kadizili, kanye nokunciphisa ukungcoliswa kwegesi.

3, Cummins generator usethe electronic valve ubuchwepheshe

Amajeneretha edizili ngesivinini esihlukene.Izidingo zokuhamba kwe-valve ziyahlukahluka kakhulu.Ngejubane eliphansi, ngoba umthamo wokungenisa uncane, uma ukuhamba kwe-valve kukhulu, ngeke kukwazi ukukhiqiza ukucindezela okwanele okungenayo, i-injector ayikwazi ukuhlanganiswa ngokugcwele nomoya ophefumulayo ngemva kokujova, okuholela ekusebenzeni kahle komlilo ophansi, I-torque yejubane eliphansi izoncishiswa kakhulu, futhi ukukhishwa kwegesi kuzokwanda.Kulokhu, i-valve encane kufanele isetshenziswe.Ngenxa yokuhamba kwe-valve encane, ukucindezelwa okungalungile kokuthatha kuyanda, futhi inani elikhulu lama-vortices eliholela lingaxuba ngokugcwele ingxube ukuhlangabezana nokusebenza okuvamile kwejeneretha ye-diesel ngesivinini esiphansi.Ngejubane eliphezulu, isimo siphambene.Ngalesi sikhathi, umthamo wokuthatha likhulu kakhulu.Uma ukuhamba kwe-valve kukuncane kakhulu, ukumelana nokuthatha kuzoba kukhulu kakhulu ukudonsa umoya owanele, ngaleyo ndlela kuthinte ukusebenza kwamandla.Ngakho-ke, ngesivinini esikhulu, kuyadingeka ukuhamba nge-valve enkulu, ukuze uthole isidingo esihle kakhulu se-valve.Ukuze kuncishiswe ukusetshenziswa kukaphethiloli, i-valve ye-BMW eguquguqukayo iqondisa inani lomoya ejeneretha likadizili hhayi nge-throttle kodwa ngokuphakamisa okulungisekayo kwevalvu edonsayo.Ngokusetshenziswa kwe-eccentric shaft eshintshwayo ngogesi, isenzo se-camshaft ku-rod valve pressure rod sishintshwa yisileva esimaphakathi, ngaleyo ndlela kukhiqizwe i-valve yokudonsa eshintshwayo.I-throttle isetshenziswa kuphela ngesikhathi sokuqala kanye nokusebenza okuphuthumayo.Kuzo zonke ezinye izimo zokusebenza i-throttle ivuleke ngokugcwele nge-throttling encane.Ubuchwepheshe be-valve ye-elekthronikhi bufinyelela ibhalansi engcono kakhulu yokukhishwa kwe-torque yamandla ejeneretha ye-diesel ngaphansi kwezimo zejubane ezihlukene ngokulungiswa okungenazinyathelo kwe-valve stroke.

Inqubekelaphambili eqhubekayo yomphakathi wanamuhla nayo iye yabangela imiphumela eminingi engemihle endaweni esihlala kuyo.Esimweni esinjalo, ngaphansi kwethonya lentuthuko yesikhathi esizayo yesayensi nobuchwepheshe besethi ekhiqizayo yekhabhoni ephansi, ukonga amandla, ukuthuthukiswa kokuvikelwa kwemvelo kuye kwaba umkhuba kancane kancane, ukuthuthukiswa kocwaningo lwesistimu yokuphuza i-diesel generator, hhayi nje usizo. siphinde siqonde ukuthuthukiswa okujwayelekile kwesistimu yokungenisa umoya ye-diesel generator, futhi ngesifundo esizayo sokuhlola i-generator air intake system kudlala indima eqondisayo, Ububi bokusetshenziswa kukaphethiloli okuphezulu kanye nezinga eliphezulu lokungcola kwamasethi e-generator kungaxazululwa isinyathelo ngesinyathelo.
