Diesel Injector Roj Injector 0445120148 Bosch rau txiv neej TGL TGM D0834lfl50 D0836lfl53

Cov nyhuv ntawm Ob Chav Injector ntawm Cov Txheej Txheem Kev Sib Txuas hauv 396 Series Diesel Cav (ib feem4)

Daim duab 3 thiab daim duab 4 qhia tau hais tias, thaum piv nrog rau cov ntaub ntawv ntawm kev siv 5-qhov injector, rooj plaub ntawm kev siv 8-qhov injector muaj qis combustion tso tawm tus nqi, siab nyob rau hauv lub tog raj kheej, nruab nrab kub nyob rau hauv lub tog raj kheej, accumulated tshav kub tso tawm thiab thermal efficiency. , thiab cov txheej txheem combustion ua tsis tiav. Tsis tas li ntawd, thaum muab piv nrog rau cov ntaub ntawv ntawm kev siv 8-qhov injector, rooj plaub ntawm kev siv 4-qhov dual-injector muaj cov txheej txheem combustion zoo dua, thiab lub siab nyob rau hauv lub tog raj kheej thiab combustion kub tso tawm tus nqi yog nruab nrab ntawm cov ntaub ntawv ntawm kev saws 5- qhov thiab 8-qhov injectors.

Txawm li cas los xij, thaum piv nrog rau cov ntaub ntawv ntawm kev siv 5-qhov injector, cov ntaub ntawv ntawm kev siv 4-qhov ob lub injector tau qis tshaj qhov nruab nrab kub hauv lub tog raj kheej, me ntsis siab dua qhov nruab nrab ntawm lub tog raj kheej thaum lub sij hawm tom kawg combustion thiab qhov tseem ceeb tib yam tso tawm cua sov. Nyob rau hauv cov xwm txheej uas lub sijhawm txhaj tshuaj thiab qhov chaw ntws zoo tsis hloov pauv, thaum lub qhov nce ntxiv thiab txoj kab uas hla tau txo qis, qhov loj ntawm cov roj txau cov khoom me me, cov atomization zoo tau zoo dua qub, tab sis qhov tob tob tob ntawm cov roj teeb tau txo qis. .

Kev faib cov roj rau hauv qhov chaw yog synthetically txiav txim siab los ntawm tus naj npawb ntawm cov nozzles thiab cov roj nkag mus deb.11, 12 kev txhim kho ntawm atomization zoo yog conductive mus rau qhov tsim ntawm ntau pre-mixed roj thaum lub sij hawm ignition ncua sij hawm thiab acceleration ntawm diffusion. combustion.

Txawm li cas los xij, raws li qhov nkag mus deb tau txo qis, cov roj tseem ceeb nyob ze ntawm lub nozzle thiab tsis sib xyaw nrog cov huab cua ntshiab ntawm qhov kawg. Qhov no ua rau txo qis cov roj sib xyaw ua ntej thaum lub sij hawm ignition ncua sij hawm thiab ncua sij hawm combustion.
