Diesel Injector Roj Injector 0445120149 Bosch rau Longgong855 Forklift Cav Weichai Wd10

Cov nyhuv ntawm Ob Chav Injector ntawm Cov Txheej Txheem Kev Sib Txuas hauv 396 Series Diesel Cav (ib ntu 5)

Thaum lub 8-qhov injector tau txais kev pom zoo, qhov cuam tshuam ntawm qhov txo qhov nkag mus rau ntawm cov txheej txheem combustion yog intensified, tag nrho cov roj faib cheeb tsam thiab pre-mixed combustion yog txo, thiab diffusion combustion yog decelerated, yog li ua rau combustion tsis tiav thiab thermal efficiency qis dua.Tom qab 4-qhov dual-injector tau txais yuav, raws li ob lub injectors yog sib cais los ntawm ib qho kev ncua deb, qhov chaw faib khoom ntawm cov roj yog dav, thiab cov nyhuv sib xyaw ntawm cov roj tsuag thiab cua hauv lub tog raj kheej yog intensified.

Txawm hais tias qhov nkag mus deb tseem luv dua thiab qhov sib xyaw ua ntej sib xyaw tseem tsawg dua li ntawm 5-qhov injector, cov cua kub tso tawm yog sib npaug rau ntawm 5-qhov injector vim tias huab cua hauv lub tog raj kheej tau siv tag nrho, cov combustion. Lub sij hawm ntawm diffusion combustion yog me ntsis ntev thiab lub combustion yog ntau tiav.Daim duab 5 qhia tau hais tias, thaum lub 8-qhov injector raug saws, qhov combustion tsis tiav, combustion siab thiab nruab nrab kub hauv lub tog raj kheej thiab tsis muaj emission qis dua.Thaum 4-qhov dual-injector tau txais yuav, NO emission yog kwv yees li 60% ntawm qhov 5-qhov injector vim qhov kub siab tshaj plaws combustion.

4 Simulation cov txiaj ntsig thiab kev tshuaj xyuas ntawm kev txhaj tshuaj luv luv ntawm 4-qhov ob-injector

Nyob rau hauv cov xwm txheej uas lub sijhawm txhaj tshuaj thiab qhov chaw ntws zoo tsis hloov pauv, qhov kev ua haujlwm thermal txo qis thaum hloov 5-qhov injector mus rau 8-qhov injector.Txawm li cas los xij, yog tias 4-qhov dual-injector tau txais, qhov kev ua haujlwm thermal tau khaws cia zoo ib yam li ntawm 5-qhov injector.Yog tias qhov kev txhaj tshuaj siab tau nce ntxiv, lub sijhawm txhaj tshuaj yog luv luv thiab qhov tob tob ntawm cov roj beam yog nce, qhov sib xyaw ntawm cov roj thiab cov cua yog ntxiv thiab cov txheej txheem combustion zoo dua.Daim duab 6, Daim duab 7 thiab daim duab 8 feem ntau qhia qhov siab ntawm lub tog raj kheej, qhov tso tawm cua sov, qhov nruab nrab ntawm qhov kub hauv lub tog raj kheej, cov cua sov tso tawm thiab tsis muaj qhov seem loj thaum txhaj lub kaum sab xis ntawm 4-qhov dual-injector yog 26.84 ° CA, 22 ° CA thiab 20° CA.
