Diesel Injector Roj Injector 095000-8981 Denso Injector rau Isuzu

1) Los ntawm kev xaav ntawm lub tshuab ua haujlwm diesel
Caprotti li al.! nyob rau hauv lub tog raj kheej, thiab lub diesel diffuses mus rau lub qhov hluav taws xob ntawm lub qhov txhaj tshuaj thiab cov roj injector. Nyob rau sab saum toj, ua kua roj zaj duab xis yog tsim; qhov kub siab nyob rau hauv lub combustion chamber ua rau cov roj Cheebtsam evaporate, thiab cov roj undergoes high-temperature cracking tshua los tsim viscous carbon deposits; cov kua qaub, kub-boiling hydrocarbons thiab lubricating roj Cheebtsam generated thaum lub sij hawm combustion txheej txheem yog nyob rau saum npoo ntawm cov carbon deposits. Kev sib sau ua ke, qhov siab diffusion ntawm cov roj diesel, qhov chaw soot nyob rau hauv lub combustion chamber thiab lwm yam kom ntseeg tau qhov ceev ntawm carbon deposit tsim; Lub hav zoov ntawm cov kua qaub ua rau qhov kub ntawm sab saum toj ntawm lub injector ib txwm siab, cuam tshuam qhov cuam tshuam ntawm cov kua roj ntawm cov pa roj carbon deposits.
2) Los ntawm qhov kev xav ntawm kev tsom xam, Lepperhoff li al. pom tias cov khoom tseem ceeb ntawm cov pa roj carbon deposits yog cov khoom siv organic (carbon, hydrocarbons, oxygen thiab nitrogen) thiab ib qho me me ntawm cov ntsiab lus inorganic (sulfur, ), los ntawm kev tsom xam ntawm cov pa roj carbon deposits; phab ntsa thiab roj Qhov nruab nrab ntawm cov tee dej yog qhov tsim nyog rau kev tsim cov pa roj carbon deposits. Feem ntau ntawm cov xov xwm tiv tauj yog hydrocarbons nrog cov ntsiab lus kub kub. Cov txheej txheem tsim ntawm cov pa roj carbon deposits yuav muab faib ua ob txoj kev: lub sij hawm induction thiab lub sij hawm loj hlob, raws li qhia nyob rau hauv daim duab 1. Ntawm lawv: (1) Thaum lub sij hawm induction lub sij hawm ntawm carbon deposition, vim qhov kub ntawm cov phab ntsa ntawm phab ntsa. , hydrocarbons nrog cov ntsiab lus kub kub yog condensed los ua ib zaj duab xis viscous ntawm phab ntsa, thiab cov khoom me me yog adsorbed vim cov ntawv nplaum nplaum; (2) Thaum lub sij hawm kev loj hlob ntawm carbon deposition, hais thiab lwm yam viscous tshuaj yog tsis tu ncua adsorbed. Lub thickness ntawm cov pa roj carbon deposition nce thiab kev txhawb zog ua rau qhov kub thiab txias ntawm cov pa roj carbon deposition nce thiab lub binding quab yuam kom txo, uas txwv qhov sib ntxiv ntawm ntau hais. Nyob rau tib lub sijhawm, qhov kev hloov pauv ntawm cov roj ua rau lub viscosity ntawm cov pa roj carbon deposits nce. Thaum cov pa roj carbon deposits txuas rau ntawm phab ntsa, nyob rau hauv lub siab ntawm lub sij hawm ntev kub, tshuaj lom neeg cov tshuaj xws li decomposition, lub cev qhuav dej, thiab polymerization yuav tshwm sim, thiab cov carbon deposit txheej yuav ntxiv compacted.
