Cov Ntsiab Cai ntawm Common Rail Cav
Solenoid lossis piezoelectric li qub ua rau muaj peev xwm tswj tau hluav taws xob zoo ntawm lub sijhawm thiab ntau npaum li cas ntawm cov roj txhaj tshuaj, thiab qhov siab dua qhov kev siv tshuab hluav taws xob ua kom muaj roj atomisation zoo dua. Txhawm rau txo lub suab nrov ntawm lub cav, lub tshuab hluav taws xob tswj hluav taws xob tuaj yeem txhaj me me ntawm cov diesel ua ntej qhov kev txhaj tshuaj tseem ceeb ("pilot" txhaj), yog li txo nws qhov tawg thiab kev vibration, nrog rau kev ua kom zoo rau lub sijhawm txhaj tshuaj thiab kom muaj nuj nqis rau kev hloov pauv hauv roj zoo. , txias pib, thiab lwm yam. Qee qhov kev tsheb ciav hlau zoo tshaj plaws ua tau ntau li tsib qhov kev txhaj tshuaj ib zaug.
Common rail engines yuav tsum tau siv sij hawm luv luv kom tsis muaj cua sov, nyob ntawm qhov kub thiab txias, thiab ua rau lub cav qis dua thiab emissions dua li qub.
Diesel cav muaj keeb kwm siv ntau hom roj txhaj tshuaj. Ob hom muaj xws li chav tsev txhaj tshuaj thiab cov distributor / inline-pump systems. Thaum cov txheej txheem qub no muab cov roj kom raug thiab kev txhaj tshuaj lub sijhawm, lawv raug txwv los ntawm ntau yam:
Lawv yog cov cam tsav, thiab kev txhaj tshuaj siab yog proportional rau lub cav ceev. Qhov no feem ntau txhais tau hais tias qhov kev txhaj tshuaj siab tshaj plaws tsuas yog ua tiav ntawm qhov siab tshaj plaws ntawm lub cav ceev thiab qhov siab tshaj plaws ua tiav qhov kev txhaj tshuaj siab txo qis thaum lub cav ceev txo. Qhov kev sib raug zoo no muaj tseeb nrog txhua lub twj tso kua mis, txawm tias cov uas siv rau hauv cov kab tsheb ciav hlau. Nrog rau chav tsev lossis cov tshuab xa tawm, qhov kev txhaj tshuaj yog khi rau lub siab ceev ntawm ib qho kev tshwm sim uas tsis muaj accumulator, yog li kev sib raug zoo yog qhov tseem ceeb thiab teeb meem.
Lawv raug txwv nyob rau hauv tus naj npawb thiab sij hawm ntawm kev txhaj tshuaj cov xwm txheej uas tuaj yeem raug txib thaum ib qho kev tshwm sim combustion. Txawm tias muaj ntau yam kev txhaj tshuaj muaj peev xwm ua tau nrog cov txheej txheem qub, nws nyuaj dua thiab raug nqi ntau dua kom ua tiav.
Rau cov neeg xa khoom raug / inline system, qhov pib txhaj tshuaj tshwm sim ntawm qhov kev txiav txim siab ua ntej (feem ntau hu ua pop siab) thiab xaus ntawm lub siab predetermined. Cov yam ntxwv no tshwm sim los ntawm " ruam" injectors nyob rau hauv lub tog raj kheej lub taub hau uas qhib thiab kaw ntawm lub siab txiav txim siab los ntawm lub caij nplooj ntoos hlav preload siv rau lub plunger nyob rau hauv lub injector. Thaum lub siab nyob rau hauv lub injector mus txog ib tug predetermined theem, lub plunger nqa thiab txhaj tshuaj pib.
