Ikhwalithi Ephakeme I-Valve Yokulawula Umzila Wesitimela Setha Umhlangano F00RJ01334 we-Diesel Injector 0445120047 0445120091 0445120093

Amavalvu e-Solenoid noma e-piezoelectric enza kube lula ukulawula kwe-elekthronikhi ngesikhathi kanye nenani lokujova uphethiloli, kanye nomfutho ophezulu owenziwa ubuchwepheshe besitimela obujwayelekile bunikeza ukushiswa kukaphethiloli okungcono. Ukwehlisa umsindo wenjini, iyunithi yokulawula ye-elekthronikhi yenjini ingajova inani elincane likadizili ngaphambi nje komcimbi omkhulu womjovo (“pilot” umjovo), ngaleyo ndlela yehlise ukuqhuma nokudlidliza kwayo, kanye nokwandisa isikhathi somjovo kanye nenani lokwehluka kwekhwalithi kaphethiloli. , ukuqala kwamakhaza, njalonjalo. Amanye amasistimu kawoyela wesitimela athuthukile enza imijovo emihlanu ngokushaywa ngakunye.

Izinjini zikaloliwe ezivamile zidinga isikhathi esifushane kakhulu ukuya kokungabikho kokushisisa, kuye ngezinga lokushisa elizungezile, futhi zikhiqiza umsindo wenjini ophansi kanye nokukhipha umoya kunamasistimu amadala.

Izinjini zikadizili ngokomlando zasebenzisa izinhlobo ezahlukene zokujova uphethiloli. Izinhlobo ezimbili ezijwayelekile zifaka isistimu yomjovo weyunithi kanye nesistimu ye-distributor/inline-pump. Nakuba lawa masistimu amadala ehlinzeka ngenani elinembile likaphethiloli nokulawula isikhathi komjovo, anqunyelwe izici ezimbalwa:

Zihamba ngekhamera, futhi umfutho womjovo ulingana nesivinini senjini. Lokhu ngokuvamile kusho ukuthi umfutho womjovo ophezulu kakhulu ungafinyelelwa kuphela ngesivinini esiphezulu senjini futhi umfutho womjovo omkhulu ofinyelelekayo uyancipha njengoba isivinini senjini sincipha. Lobu budlelwano buyiqiniso kuwo wonke amaphampu, ngisho nalawo asetshenziswa kumasistimu kaloliwe ajwayelekile. Ngeyunithi noma amasistimu okusabalalisa, ingcindezi yomjovo iboshelwe kungcindezi esheshayo yomcimbi wokumpompa okukodwa ngaphandle kwe-accumulator, ngaleyo ndlela ubudlelwano bugqame kakhulu futhi buyinkinga.

Zikhawulelwe enanini nasesikhathini semicimbi yomjovo engakwazi ukuyalwa ngesikhathi somcimbi owodwa wokusha. Nakuba imicimbi eminingi yokujova ingenzeka ngalawa masistimu amadala, kunzima kakhulu futhi kubiza ukufeza.

Kuhlelo olujwayelekile lomsabalalisi/umugqa, ukuqala komjovo kwenzeka ngengcindezi enqunywe kusengaphambili (evame ukubizwa ngokuthi ingcindezi ye-pop) futhi iphela ngengcindezi enqunywe kusengaphambili. Lesi sici siphumela kuma-injection "ayisimungulu" kukhanda lesilinda elivuleka futhi livale ngokucindezela okunqunywe ukulayisha kuqala kwentwasahlobo okusetshenziswe ku-plunger kumjovo. Uma ingcindezi kumjovo isifinyelele ezingeni elinqunywe kusengaphambili, i-plunger iyaphakamisa futhi umjovo uyaqala.
