Injector ya Mafuta a Dizilo 0445120188 Bosch ya Dodge RAM 2500 / RAM 3500 Pickup Truck 6.7L High-output Cummins

Kupanga Njira Yowunikira Njira Yojambulira Mafuta a Injector ya Injini za Dizilo(Gawo 5)

Chifukwa cha kupasuka, jet yamafuta imasinthidwa kukhala mafuta opopera ndi kugawa kwamtundu winawake. Kuphatikiza apo, kuchuluka kwa dontho kumakhala kosalekeza kosalekeza, mwachitsanzo, kumatha kutenga phindu lililonse pakanthawi katchulidwe kake. Pachifukwa ichi, kutsitsi mafuta kuyenera kuganiziridwa osati monga kudzikundikira kapena madontho, koma monga static aggregate ya madontho osiyanasiyana.

Malinga ndi malamulo ogawa omwe amaganiziridwa, osachepera magawo awiri amafunikira kuti aphunzire kuchuluka kwa mafuta a atomu: kuchuluka kwa dontho lapakati ndi mawonekedwe a jet (kubalalitsidwa, mtundu).

Njira ya Sauter mean drop diameter idasankhidwa. Zimayimira chiŵerengero cha kuchuluka kwa madontho onse pamtunda wawo wonse.

Kuyika kwa mafuta kumadalira nambala ya Weber, yomwe ndi chiwerengero chopanda malire chomwe chimakhazikitsa ubale pakati pa magawo atatu omwe amakhudza ubwino wa atomization yamadzimadzi ndikupezeka kuchokera ku mawuwo.

(2) :DP -Pressure dontho, 2 H/m pakati pa nozzle orifice ndi sing'anga kumene jekeseni ikuchitika cd -nozzle orifice awiri, m; s - kupsinjika kwamafuta pamtunda, N/m Limodzi mwa malamulo oyambira a capillary phenomena omwe amakhudza kuwongolera kwa atomization ndi lamulo la Laplace.

Dongosolo lopanda dimensionless limalumikiza magawo anayi omwe amakhudza kuwongolera kwa mafuta atomu (3)rT - kachulukidwe wamafuta kg/m3 pakati pa mphuno ndi sing'anga pomwe jakisoniyo amachitira; cd - nozzle orifice awiri, m; σ - kupsinjika kwamafuta pamtunda, N/m, mT - kukhuthala kwamafuta, Ns/m2

A kwambiri zotsatira mafuta atomization amayamba ndi mlingo umene madzi umayenda kuchokera nozzle orifice. Kuchuluka kwa mafuta omwe amatuluka pomwe kupasuka kumayambira nthawi yomweyo potuluka pamphuno kumadalira zinthu zingapo (4):
