Isitofu sikagesi sikagesi saziwa nangokuthi i-EUI, sisebenza kanjani?Isimiso sayo sokusebenza simane nje ukuthi isignali ye-elekthronikhi ekhishwe yi-ECM ithunyelwa ku-valve ye-solenoid, elawula ukuvulwa nokuvalwa kwe-valve yenaliti, ngaleyo ndlela idlulisele inani elithile lamafutha ngaphakathi komjovo.Inani nobude besikhathi somjovo kulawulwa ngokunembile yi-algorithm ye-ECM ne-MAP.Inani lomjovo kaphethiloli linqunywa isikhathi somjovo kanye nesivinini se-plunger yomjovo, futhi liyalingana.Isikhathi lapho i-valve ye-solenoid inikwe amandla yisiqalo somjovo wamafutha, futhi ukulahlekelwa amandla ukuphela komjovo wamafutha.Nazi izinyathelo ezine eziqondile zokusebenza komjovo.
Ukumunca unhlangothi
Ishaneli yamafutha ixhunywe esihlokweni sesilinda senjini ukuze ilethe uphethiloli ngekhanda lesilinda kuma-injection angawodwana, ngakho ukwakheka kolayini kaphethiloli kufanele kuqinisekise ukuthi izinga lokushisa likaphethiloli liyavumelana phakathi kwama-injection.Ngemva kokuba uphethiloli ugeleza ku-injector, uphethiloli ugcinwa futhi upholile ekamelweni langaphakathi, kuyilapho amanzi kanye ne-steam kuphethiloli kwenziwa.Phakathi nalesi sifo, i-plunger yomjovo iyakhuphuka futhi uphethiloli uthele kumjovo, ugcwalise imbobo yomjovo.
Umjovo unhlangothi
Lapho i-plunger yokujova iqala ukwehla, uphethiloli ongaphansi kwe-plunger uphoqeleka ukuba uphume kumjovo bese ubuyiselwa kumjikelezo kaphethiloli.Uma i-ECM ingabonisi i-valve ye-solenoid, khona-ke yonke izobuyela kumjikelezo kaphethiloli.Lapho i-ECM inikeza isignali ku-valve ye-solenoid, i-valve yenaliti elawulwa yi-solenoid valve ivaliwe, futhi uphethiloli awukwazi ukubuyela kumjikelezo kaphethiloli, futhi ingcindezi iyaqhubeka nokwanda njengoba i-plunger iqhubeka nokwehla, iba phezulu. -uphethiloli wokucindezela, ukuphoqa i-valve ye-nozzle ukuthi ivule futhi iqale ukufutha.Ingcindezi ephezulu yomjovo ayikho ekuqaleni komjovo, kodwa ngasekugcineni komjovo.
I-stroke esele
Umjovo uyaqhubeka kuze kube yilapho i-valve ye-solenoid ilahlekelwa amandla, ngaleso sikhathi i-valve yenaliti ye-solenoid ivula, amafutha aphezulu okucindezelayo akhululiwe, angena kumjikelezo wamafutha, futhi i-valve yokujova ivaliwe.
