Kodi chidebe cha kaboni cha galimoto n'chiyani?
Chidebe cha kaboni nthawi zambiri chimayikidwa pakati pa thanki yamafuta ndi injini. Popeza mafuta ndi madzi osasunthika, thanki yamafuta nthawi zambiri imadzazidwa ndi nthunzi pa kutentha kwabwinobwino. Ntchito ya dongosolo lowongolera kutulutsa kwa mafuta ndikulowetsa nthunzi mu kuyaka ndikuletsa kuti isatuluke mumlengalenga. Chipangizo chosungiramo thanki ya kaboni yoyendetsedwa ndi activated chimagwira ntchito yofunika kwambiri pankhaniyi.
Popeza mpweya woyatsidwa umakhala ndi ntchito yolowetsa mpweya, galimoto ikamayenda kapena kuzimitsa, nthunzi ya petulo kuchokera mu thanki yamafuta imalowa kumtunda kwa chidebe cha mpweya choyatsidwa kudzera mu payipi, pomwe mpweya watsopano umalowa mu chidebecho kuchokera pansi. Injini ikazima, nthunzi ya petulo imasakanikirana ndi mpweya watsopano mu thankiyo ndipo imasungidwa mu chidebe cha mpweya choyatsidwa. Injini ikayamba, valavu yamagetsi ya chipangizo choyeretsera mpweya woyatsidwa ndi mpweya chomwe chimayikidwa pakati pa chidebe cha mpweya choyatsidwa ndi manifold yolowera imatsegulidwa, ndipo nthunzi ya petulo mu chidebe cha mpweya choyatsidwa imayamwa mu intake manifold kuti igwire nawo ntchito yoyaka.
Mafuta a petulo ndi mafuta osinthasintha. Mafuta omwe ali mu thanki yamafuta amasungunuka mwachangu, zomwe zimawonjezera kupanikizika mkati mwa thanki. Kupanikizika kukafika pamtengo winawake, kumabweretsa zoopsa zina. Chifukwa chake, anthu anayesa kulinganiza kupanikizika. Poyamba, chivundikiro cha thanki yamafuta chinkapangidwa kukhala valavu yochepetsera kupanikizika. Kupanikizika kukapitirira mtengo winawake, valavu yochepetsera kupanikizika imatsegula ndikutulutsa nthunzi ya petulo mumlengalenga. Pambuyo pake, Kuchokera pakuwona kusunga mafuta ndi kuteteza chilengedwe, anthu akhazikitsa zitini za kaboni. Mkati mwa chitini cha kaboni mumadzazidwa ndi kaboni wokhuthala kwambiri. Nthunzi yochulukirapo yamafuta mu thanki yamafuta simatulutsidwanso mumlengalenga koma imalowetsedwa mu chitini cha kaboni chokhuthala kudzera mu chitoliro. Ndi kaboni wokhuthala womwe umayamwa nthunzi yamafuta. Galimoto ikamayenda, valavu ya solenoid ya chitini cha kaboni chokhuthala imatsegulidwa nthawi yake, ndikubwezeretsanso nthunzi yamafuta yomwe imayamwa mu intake manifold kuti ikwaniritse cholinga chosunga mafuta ndi kuteteza chilengedwe.
Injini ikapanda kugwira ntchito, phokoso la "tap-tap" limamveka nthawi ndi nthawi. Musachite mantha mukakumana ndi vuto lotere. Choyamba choti muchite ndikupeza valavu ya solenoid ya carbon canister mgalimoto ndikuwona ngati phokoso la "dada" likuchokera mgalimotomo. Ngati ndi choncho, ingonyalanyazani. Chifukwa throttle ikatsegulidwa, valavu ya solenoid ya carbon canister imapanga zochitika zina ndikupereka mawu, ndipo izi ndi zachilendo.
Mukaponda pa accelerator ndikuyimitsa galimoto, mumamva fungo lamphamvu la mafuta mkati mwake
Ngati mukukumana ndi vuto pamene galimoto imaima mukaponda accelerator kuti ifulumire ndipo pali fungo lamphamvu la mafuta mkati, muyenera kusamala kwambiri ngati mapaipi omwe ali mu carbon canister system awonongeka. Nthunzi ya mafuta idzatulutsidwa mwachindunji mumlengalenga motsatira malo owonongeka, zomwe zimapangitsa fungo lamphamvu la mafuta mkati mwa galimotoyo. Ngati panthawiyi payipiyo imatulutsa mafuta, zomwe zimapangitsa kuti mpweya m'malo mwa nthunzi ya mafuta ulowe munjira yolowera injini, mosakayikira zidzatsogolera ku kusakaniza kwa injini kopanda mphamvu kwambiri, motero kupangitsa kuti injini iimirire nthawi zina.
Liwiro la injini limasintha pang'onopang'ono ndipo liwiro lake ndi lofooka
Ngati injini yayamba ndipo liwiro la idle limasintha nthawi zonse ndipo galimoto ili ndi liwiro lofooka, ndikofunikira kusamala ngati izi zimachitika chifukwa cha kutsekeka kwa mpweya wolowera mu chidebe cha kaboni ndi chophimba chosefera. Chifukwa panthawiyi, zimakhala zovuta kuti mpweya wakunja ulowe mu chidebe cha kaboni, ndipo pali kusowa kwa mpweya wabwino mkati mwa chidebecho. Pa liwiro la idle, pansi pa mphamvu ya intake vacuum suction, nthunzi ya petulo yomwe imalowa mu chidebe cha kaboni choyambitsidwa imayamwa mu intake manifold, zomwe zimapangitsa kuti sensa ya okosijeni izindikirike kuti ndi yolemera kwambiri. Zotsatira zake, gawo lowongolera injini limachepetsa kuchuluka kwa ma injectors amafuta, ndipo kuchuluka kwa osakaniza omwe amayaka kumachepa moyenerera, zomwe zimapangitsa kuti liwiro la idle lichepe. Pambuyo pake, chifukwa cha kuchepa kwa kuchuluka kwa injection yamafuta, sensa ya okosijeni idazindikira kuti osakanizawo anali ochepa kwambiri munthawi yotsatira. Zotsatira zake, kompyuta idawonjezeranso kuchuluka kwa injection yamafuta, zomwe zidapangitsa kuti liwiro la idle lipitirire kukwera. Chifukwa chake, chodabwitsa cha idle speed kusinthasintha nthawi zonse chimachitika. Choncho, ngati zoterezi zitachitika, mwini galimoto ayenera kufufuza mwachangu ngati mpweya womwe umabwera mu chidebe cha kaboni sunatseguke.
Injini yaima kapena yavuta kuyiyambitsa
Pakadali pano, ndikofunikira kuyang'anitsitsa valavu ya solenoid ya kaboni yomwe ingayambitse mavuto. Ngati valavu ya solenoid ikhala yotsekedwa nthawi zonse, nthunzi ya petulo yomwe ili mu kaboni idzasonkhana kwambiri, pamapeto pake idzadzaza kaboni yonse. Nthunzi ya petulo yotsalayo imatha kungotuluka mumlengalenga, kuipitsa chilengedwe ndikuwononga mafuta. Mosiyana ndi zimenezi, ngati valavu ya solenoid ikhala yotseguka nthawi zonse, chisakanizo chomwe chili mu doko lolowera injini chidzawonjezeka nthawi zonse. Nthawi yomweyo, popeza gawo lowongolera injini silinayang'anire valavu ya solenoid ya kaboni kuti igwire ntchito, silidzapereka lamulo lochepetsa kuchuluka kwa mafuta omwe amalowa. Izi zipangitsa kuti chisakanizocho chikhale cholemera kwambiri injini ikatentha, zomwe zimapangitsa kuti injini iziyima, komanso zimapangitsa kuti zikhale zovuta kuyambitsa injini ikatentha komanso kuyima.
Mfundo yachiwiri yomwe eni magalimoto ayenera kuiganizira ndi yakuti asadzaze thanki nthawi zonse. Kumbukirani kudzaza pang'onopang'ono ikadzala. Kudzaza mafuta mopitirira muyeso kungayambitse kuti mafuta alowe m'mapaipi a makina opangidwa ndi mpweya wa carbon. Kulowa kwa mafuta amadzimadzi amenewa mu chidebe cha carbon sikuti kumangowopseza chidebecho chokha komanso kumadutsa m'mapaipiwo kupita munjira yolowera, zomwe zimapangitsa kuti ma spark plugs "amire", zomwe zimapangitsa kuti pakhale mavuto aakulu monga galimoto kuyima ikadzala mafuta kenako nkulephera kuyaka. Ngati mudzaza mafuta mofulumira kwambiri, ngati nthunzi yomwe ikukula ndi mpweya womwe umatulutsidwa ndi mafuta sizingatulutsidwe panthawi yake, zingayambitse kutsekeka kwa mafuta.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
