Mechanism ntawm injector carbon deposit formation part 2
- 3) Los ntawm kev xaav ntawm cov txheej txheem thermal oxidation ntawm diesel xyaw, Singer li al. siv cov roj roj ntshiab huv rau kev kho cua sov, kawm txog qhov kub thiab txias ntawm lub sijhawm ntawm kev tsim cov pa roj carbon deposits hauv thermal oxidation cov tshuaj tiv thaiv ntawm cov roj diesel, thiab ntseeg hais tias kev tsim cov pa roj carbon deposits feem ntau nyob ntawm qhov kub thiab txias ntawm cov diesel raug, thiab cov txheej txheem tsim cov pa roj carbon deposits tau muab faib ua ob theem hauv qab no: 1) Thaum cov roj diesel raug kub siab tshaj 140C, tom qab cua sov hauv huab cua ntev ntev, cov roj diesel degrades. thiab decomposes, thiab ib feem ntawm nws tsim siab molecular hnyav oxidized diesel cov khoom (High Molecular Nyhav Oxygenated Roj Khoom, MOFP), lub sij hawm no MOFP tuaj yeem ntxiv oxidize nrog cov evaporated diesel, thiab tej zaum yuav raug tshem tawm los ntawm cov diesel huv si; Thaum lub tshuab hluav taws xob raug kub qis dua 140C, txawm tias nws tsis tu ncua cua sov rau ob peb teev, Tsis muaj kev tsim MOFP pom tseeb 2) Thaum MOFP tau rhuab mus rau 150C, MOFP pib tsim bifurcated siab molecular hnyav tshuaj. Thaum lub sij hawm cua sov luv luv, feem ntau ntawm cov khoom tseem yuav raug tshem tawm los ntawm cov roj diesel; Raws li cov cua kub kub nce Raws li qhov kub thiab txias lub sij hawm ntev, lub MOFP nce tsis tu ncua, thiab thaum lub kub tseem ceeb nce mus txog 300C, feem ntau ntawm cov khoom tsim ib tug insoluble thiab interconnected polymeric network, thiab thaum kawg tsim carbon deposits.
4) 4) Los ntawm kev xav ntawm kev ntxiv zinc, Ikemoto li al. [0] npaj cov txheej txheem tsim cov pa roj carbon deposits nyob rau hauv lub nozzle qhov ntawm cov roj injector thaum zinc ntsiab tau ntxiv rau diesel, thiab ntseeg hais tias thaum lub diesel roj uas muaj zinc ntsiab yog siv, cov txheej txheem tsim carbon deposit nyob rau hauv lub nozzle qhov yuav ua tau. Nws tau muab faib ua peb theem, raws li qhia hauv daim duab 2: (1) Hauv thawj theem, txij li lub qhov hluav taws xob ntawm lub qhov nozzle yog ze rau cov roj combustion, qhov kub thiab txias yog siab dua, yog li cov pa roj carbon ntau dua. yog tsim, thaum lub qhov kub ntawm lub qhov nozzle yog qis dua, thiab cov pa roj carbon deposits tsawg dua. Zinc reacts nrog me me ntawm anteline acid nyob rau hauv combustion gas los tsim zinc antelope, uas tsim ib tug bottleneck ntawm lub qhov hluav taws xob ntawm lub qhov hluav taws xob txhaj tshuaj, txwv tsis pub khiav ntawm diesel; Cov pa roj carbon deposits ntawm lub qhov nkag ntawm lub qhov nozzle tsim zinc carbonate, thiab zinc anteline ntawm qhov hluav taws xob ntawm lub nozzle qhov maj mam nce mus txog saturation (lub zinc carbonate decomposes raws li qhov kub thiab txias), thiab cov pa roj carbon deposits maj mam nce mus rau nruab nrab thiab lub inlet sab ntawm lub nozzle qhov; (3) lub xeev saturated, zinc carbonate ntawm qhov nkag ntawm lub qhov nozzle maj mam nce mus txog saturation, thiab tsim ib lub fwj ntawm lub qhov hluav taws xob ntawm lub nozzle qhov, lub sij hawm no muaj qhov sib npaug ntawm kev tsim thiab tshem tawm cov pa roj carbon deposits.
