Diesel Injector Roj Injector 0445120408 tau tshaj Bosch injector Case New Holland

Influence ntawm Injector Structure ntawm Diesel Cav Performance thiab Emissions

Los ntawm ESC xeem voj voog thiab khov kho-lub xeev tag nrho-load test, combustion system sib piv cov tswv yim uas ua tau raws li qhov yuav tsum tau txiav txim.Cov ntsiab lus xaus yog raws li nram no:
q) Nyob rau hauv tag nrho cov load, piv engine kev ua tau zoo ntawm injector txaus tus nqi ntawm 750mL / nyob rau hauv thiab 610mL / min.Cov txiaj ntsig tau pom tias thaum qhov ceev ntau dua 1600R / min, tus nqi pa luam yeeb thiab roj siv tus nqi sib raug rau 750mL / min yog qhov qis, tab sis NO thiab emission tus nqi siab dua me ntsis.Cov txiaj ntsig ntawm ESC xeem tau pom tias lub cav feem ntau emissions poob thaum lub injector flow rate yog 750mL min.Yuav kom ua tau raws li lub teb chaws IV emission yuav tsum tau rau particle emissions thiab nyob rau tib lub sij hawm integrate tag nrho cov load ntawm lub cav, 750mL / min raug xaiv raws li qhov optimized parameter ntawm lub injector txaus.) Tag nrho-load kev ua tau zoo nkhaus ntawm 148 ° thiab 150 nozzle lub khob hliav qab yog qhov zoo ib yam.Cov txiaj ntsig ntawm ESC cov qhabnias qhia tau tias lub cav kev lag luam zoo dua thaum lub kaum sab xis ntawm lub taub hau yog 148, thiab cov khoom siv hluav taws xob tsawg tsawg.Yog li ntawd, lub optimized nozzle lub khob hliav qab yog xaiv los ntawm 148 °
6) Thaum lub sij hawm optimization txheej txheem, kev sim tau ua rau txawv nozzle protrusions.Nyob rau hauv tag nrho cov load, ntawm qhov ntsuas ceev taw tes, lub hwj chim ntawm lub nozzle protrusion ntawm 2.0mm yog me ntsis qis, qhov txawv yog hais txog 2kw, tab sis nws tau ua raws li qhov yuav tsum tau.Txawm li cas los xij, ntawm tag nrho cov load, cov pa luam yeeb theem thaum lub nozzle protrusion yog 2.0 hli me dua li ntawm ob hom nozzle protrusions.Kev ntsuam xyuas ESC qhia tau hais tias qhov emission theem ntawm NO, CH, CO, thiab soot yog ib yam nkaus thaum lub nozzle protrusions txawv.Thaum lub protrusion ntawm lub nozzle yog 2.0 hli, particle emission ntawm lub diesel cav yog ho txo.Yog li ntawd, nyob rau hauv dav dav, lub nozzle protrusion ntawm 2.0mm yog qhov zoo tshaj plaws, thiab yuav siv nyob rau hauv lub tom ntej optimization tsim.
