Kev paub txog diesel injector
Simulation Kawm txog qhov cuam tshuam ntawm qhov tsis sib xws ntawm cov roj txhaj tshuaj ntawm txhua lub qhov ntawm Diesel Cav Injector ntawm cov txheej txheem combustion(PIB 4)
Kev txo qis ntawm qee cov tshuaj tua hluav taws tau nrawm dua nyob ib puag ncig cov tshuaj txau nrog cov tshuaj tua kab mob siab thaum ntxov, qhov hluav taws kub tshwm sim ntawm 348 ° CA [11]. Txawm li cas los xij, nyob rau hauv qhov kev txhaj tshuaj zoo ib yam, qhov chaw kub kub tseem ceeb tshwm sim ntawm 350 ° CA, thiab cov roj ignition tshwm sim hauv lub tog raj kheej. Nws tuaj yeem pom tau tias, nyob rau hauv qhov tsis sib xws ntawm cov roj txhaj tshuaj, qee qhov uas muaj kev txhaj tshuaj siab ua rau lub sijhawm ua kom tsis muaj zog thiab ua rau lub combustion pib ua ntej. Tom qab pib combustion, nws yog nyob rau theem ntawm piston nce mus txog rau saum toj kawg nkaus qhov chaw tuag [12]. Qhov kub thiab siab nyob rau hauv lub tog raj kheej nce ceev ceev, lub turbulence ntawm huab cua khiav yog ntxiv dag zog, cov roj vaporization, atomization thiab sib tov, thiab lub ignition mob yog ceev, yog li ntawd lub combustion yog sai [13].
Qhov kub thiab siab nyob rau hauv lub tog raj kheej accelerate atomization ntawm cov roj hais. Daim duab 4 qhia tau hais tias, feem ntau ntawm cov khoom siv roj txau nyob rau lub sijhawm thaum ntxov ntawm Kev Tsis Txaus Siab tau vaporized thiab atomized ntawm 355 ° CA; Yog li ntawd, cov roj ntau tuaj yeem siv rau kev sib tsoo, thiab qhov kub thiab txias hauv lub tog raj kheej yog qhov siab dua li cov nyob hauv Cov Txheej Txheem. Cov khoom siv roj tau txo qis, qhov concentration ntawm cov roj cov khoom nyob ze rau ntawm phab ntsa saum npoo hauv chav combustion yog qhov siab dua, qhov kub thiab txias ntawm lub tog raj kheej yog dav, qhov kub thiab txias ntawm lub tog raj kheej tau nthuav dav, thiab NO tiam yog nce vim siab dua. thiab dav dua nyob rau hauv-lub tog raj kheej kub faib thaum piv nrog cov ntawm 360 ° CA ntawm even Condition [14]. Nyob rau ntawm 380 ° CA, qhov kub ntawm qhov kub thiab txias ntawm Txawm tias qhov xwm txheej thiab qhov xwm txheej tsis sib xws yuav luag zoo ib yam, piv nrog cov roj ntau ntxiv rau kev sib tsoo thaum ntxov ntawm qhov tsis sib xws, cov khoom siv roj ntau dua yog siv rau kev sib tsoo ntawm Txawm li cas los xij, cov roj tiv thaiv hauv thaj chaw sab nraud ntawm lub qhov yog qhov sib xws, cov huab cua ntim kuj muaj ntau, yog li cov combustion txaus.
