Caterpillar 35A Series Roj Injector
Kev Tsim Qauv thiab Kev Ua Haujlwm Engineering
Cov roj txhaj tshuaj no yog tsim los ntawm HEUI (Hydraulic Electronic Unit Injector) lossis MEUI (Mechanically actuated Electronic Unit Injector) architecture nyob ntawm seb hom twg, muab lub sijhawm txhaj tshuaj electronically modulated thiab tswj kom muaj nuj nqis nyob rau hauv qhov siab.
Cov yam ntxwv tseem ceeb ntawm kev tsim kho vaj tse:
Kev Txhaj Tshuaj Siab: Txog li 1600 bar (160 MPa)
Qhov Loj ntawm Lub Qhov Tsuag: Feem ntau 0.2–0.8 hli
Nozzle Configuration: Ib lub qhov, ntau lub qhov, orifice phaj (nyob ntawm tus qauv tsim lub taub hau kheej kheej)
Solenoid Tsis kam: Qis-impedance (2–3 Ohms) lossis siab-impedance (13–16 Ohms) variants
Cov Khoom Siv Muaj: Cov hlau carbon thiab cov carbide-coated hnav nto kom tiv taus cov voj voog siab thiab kev ntxhov siab thermal
Kev Tswj Roj: Kev tswj solenoid modulated pulse-width nrog ECU-trimmed fuel mapping
Kev Tsim Qauv thiab Kev Ua Haujlwm Engineering
Kev Ua Haujlwm thiab Lub Luag Haujlwm hauv Kev Ua Haujlwm ntawm Cav
Cov roj txhaj tshuaj hauv 35A Series ua kom ntseeg tau tias:
Kev ntsuas roj av meej thoob plaws ntau qhov xwm txheej ntawm lub cav
Kev ua kom zoo dua ntawm atomization rau kev ua kom zoo dua ntawm kev hlawv
Txo cov pa phem (NOx, PM) los ntawm kev siv cov qauv tshuaj tsuag zoo tshaj plaws
Siv tau ntev dua lub neej ntawm lub koob txhaj tshuaj los ntawm kev sib dhos lub qhov (valve) koob thiab lub plunger uas khov kho
