I-Diesel Genset Elawulwa Ngogesi VS EFI Diesel Genset

Uyini umehluko phakathi kwesethi yejeneretha kadizili elawulwa ngogesi kanye ne-EFI generator diesel?

Ngokwemodi yokulawula isivinini ye i-diesel genset , Injini ye-EFI nesilawuli sikagesi siyingxenye yesigaba sokulawulwa kwesivinini sikagesi.Ahlukile kumodi yokulawula isivinini ngomshini, engafaniswa nalezi zici ezilandelayo:

Okokuqala, ingcindezi yokujova uphethiloli.

Isilawuli sikagesi sijova ngokuqondile udizili kusilinda ngepompo evamile yokucindezela okuphezulu, futhi ukucindezela komjovo wayo kukhawulwa yivalvu yokucindezela kumjovo.Ngemuva kokuthi ingcindezi kaphethiloli epayipini likawoyela elinengcindezi ephezulu ifinyelele inani elibekiwe le-valve yokucindezela, iphuthuma ivule i-valve bese iyijova kusilinda.Ethonywe ukukhiqizwa kwemishini, ukucindezela kwe-valve yokucindezela akukwazi ukuba kukhulu kakhulu.

Injini ye-EFI iqala ikhiqize uwoyela onengcindezi ephezulu egumbini likawoyela elinomfutho ophezulu wesijobi sikaphethiloli ngepompo likawoyela elinomfutho ophezulu.Umjovo kaphethiloli we-fuel injector ulawulwa yi-valve ye-solenoid.Uma umjovo kaphethiloli udingeka, isistimu yokulawula i-elekthronikhi ilawula i-valve ye-solenoid ukuze ivule futhi ijove uwoyela wengcindezi ephezulu kusilinda.Ukucindezela kwamafutha aphezulu akuthintwa i-valve yokucindezela futhi kungandiswa kakhulu.Ingcindezi yokujova udizili inyukile isuka ku-100MPa iye ku-180MPa.Umfutho onjalo womjovo ophezulu ungathuthukisa kakhulu izinga lokuxutshwa likadizili nomoya, unciphise isikhathi sokulibaziseka, wenze ukusha kusheshe futhi kucace kakhudlwana, futhi ulawule izinga lokushisa lomlilo, ukuze kuncishiswe ukuthuthwa kwegesi.

Okwesibili, ukulawulwa kwengcindezi yomjovo ozimele.

Ingcindezi yomjovo wesistimu yokuhlinzeka kawoyela yephampu kawoyela enengcindezi ephezulu yenjini elawula ugesi ihlobene nesivinini nomthwalo wenjini ye-diesel, engathandeki emnothweni kaphethiloli kanye nokuphuma ngaphansi kwezimo zejubane eliphansi kanye nomthwalo oyingxenye. .

Uhlelo lokunikezwa kukaphethiloli lwenjini ye-EFI lunamandla okulawula ingcindezi yomjovo ngaphandle kwesivinini nomthwalo.Ingakhetha ukucindezela komjovo ofanele ukuze kuthuthukiswe ubude besikhathi somjovo kanye nesikhathi sokulibaziseka kokuthungela, futhi yenze umoya okhipha umoya wenjini kadizili ube phansi futhi ukonga ngaphansi kwezimo ezihlukahlukene zokusebenza.

Okwesithathu, ukulawula isikhathi komjovo kaphethiloli ozimele.

Ipompo yengcindezi ephezulu yesilawuli sikagesi iqhutshwa yi-camshaft yenjini, futhi isikhathi sokujova kwayo sincike ngqo ku-angle yokujikeleza ye-camshaft.Ngemuva kokuthi umshini usulungisiwe, isikhathi sokujova kwawo sesilungisiwe.

Isikhathi sokujova somshini we-EFI silungiswa ngokuphelele yi-valve ye-solenoid elawulwa uhlelo lokulawula i-elekthronikhi.Ikhono lokulawula isikhathi somjovo ngaphandle kokuzungezisa umshini isilinganiso esibalulekile sokuthola ibhalansi enhle phakathi kokusetshenziswa kukaphethiloli nokukhipha umoya.

Okwesine, umthamo wokunqanyulwa uwoyela osheshayo.

Uphethiloli kufanele unqanyulwe ngokushesha ekupheleni komjovo.Uma uphethiloli ungeke unqanyulwe ngokushesha, udizili ojovwe ngaphansi kwengcindezi ephansi uzokhipha intuthu emnyama ngenxa yokungashisi okwanele futhi kwenyuse ukukhishwa kwe-HC.

Ivalvu yokuvala i-electromagnetic enesivinini esiphezulu esetshenziswa kumjovo wenjini kadizili ye-EFI kulula ukubona ukunqanyulwa kukaphethiloli ngokushesha, kodwa iphampu kawoyela enengcindezi ephezulu yesilawuli sikagesi ayikwazi ukwenza lokhu.

Okwesihlanu, imodi yokuqalisa yokulawula isivinini.

Okulawulwa ngogesi isethi ye-diesel generator ungumbusi ophakela emuva isignali yesivinini somshini ngokusebenzisa inzwa yesivinini.Umbusi uguqulela umehluko kusignali yokulawula isivinini ngokuqhathanisa inani lesivinini esisethiwe futhi ushayela i-actuator ukuthi ilawule indawo yokubeka uwoyela noma umkhono wokuslayida ukuze ibone ukulawulwa kwesivinini.Isignali yokunikezwa kukawoyela imane incike esignali yesivinini, futhi ukulungiswa kokunikezwa kukawoyela kubonakala ngesenzo somshini we-actuator.

Umshini we-EFI usebenzisa izinzwa ezifana nesivinini, isikhathi somjovo, izinga lokushisa lomoya wokungena, ukucindezela komoya, izinga lokushisa likaphethiloli kanye nokushisa kwamanzi okupholisa ukuze kufakwe imingcele etholwe ngesikhathi sangempela kukhompyutha (ECU) ngesikhathi esifanayo, iqhathanise nokugcinwa okugciniwe. setha amanani epharamitha noma amamephu wepharamitha (imephu), bese uthumela imiyalo ku-actuator (i-solenoid valve) ngokwenani elihle noma inani eliqondiwe elibaliwe ngemva kokucubungula nokubala.
