Kodi nozzle ya mafuta ya unyolo wa nthawi ya galimoto ndi chiyani?
Cholumikizira cha unyolo wa nthawi yamagalimoto ndi gawo lofunikira kwambiri pamakina operekera mafuta a injini. Ntchito yake yayikulu ndikupopera mafuta oyezedwa molondola m'chipinda choyaka cha injini mu mawonekedwe a nthunzi kuti zitsimikizire kuti mafutawo akhoza kuyaka kwathunthu, motero kukonza magwiridwe antchito ndi magwiridwe antchito a injini.
Mfundo yogwirira ntchito
Mlomo wothira mafuta ndi valavu ya solenoid. Pamene chipangizo chowongolera zamagetsi (ECU) chitumiza malangizo, mphamvu yamagetsi imadutsa mu coil mu mlomo wothira mafuta, ndikupanga malo ogwiritsira ntchito magetsi, zomwe zimapangitsa kuti valavu ya chothira mafuta itsegule, ndipo mafutawo amathiridwa kuchokera mu dzenje lothira mafuta pa liwiro lalikulu kuti apange nthunzi, zomwe zimapangitsa kuti kuyaka kwathunthu kuyake.
Makhalidwe a kapangidwe kake
Mphuno nthawi zambiri imakhala ndi cholumikizira cha solenoid, singano ya valavu, ndi dzenje lopopera. Cholumikizira cha solenoid chikapatsidwa mphamvu, singano ya valavu imayamwa ndipo dzenje lopopera limatsegulidwa. Mafuta amathiridwa mwachangu kudzera mumpata wa annular pakati pa singano ya shaft ndi dzenje lopopera, ndikupanga utsi.
Malangizo okonza
Kusamalira nozzle yolowetsa mafuta ndikofunikira kwambiri, chifukwa momwe imagwirira ntchito zimakhudza mwachindunji magwiridwe antchito a injini. Kuyeretsa nozzle nthawi zonse kumatha kuletsa kusonkhanitsa kwa kaboni ndi zinyalala kuti zisatseke nozzle, kuonetsetsa kuti mafuta akupezeka molondola komanso kuti injini ikugwira ntchito bwino. Nthawi zambiri amalangizidwa kuyeretsa nozzle ya mafuta nthawi zonse malinga ndi momwe galimoto ilili komanso mtundu wa mafuta, ndipo nthawi zambiri amalangizidwa kuyeretsa kamodzi pa makilomita 20,000 aliwonse.
Ntchito yaikulu ya nozzle ya unyolo wa nthawi yagalimoto ndikugwirizanitsa nthawi yoyatsira ya makina a valavu kuti zitsimikizire kuti mafuta amatha kulowetsedwa mu silinda nthawi zonse komanso mochuluka, kuti akonze bwino kuyaka. Makamaka, nozzle ya mafuta imayang'anira kuyatsidwa kwa mafuta kudzera mu valavu ya solenoid, kuti mafuta azithiridwa mu chifunga, zomwe zimathandiza kusakaniza mafuta ndi mpweya wonse, kukonza bwino kuyaka, motero kukulitsa magwiridwe antchito amagetsi agalimoto .
Mfundo yogwirira ntchito ya nozzle ya mafuta
Nozzle ndi chipangizo cha solenoid valve, pamene solenoid coil yapatsidwa mphamvu, imapanga mphamvu yotsegula nozzle, kuti mafuta afafazidwe mu chifunga. Ikhozanso kulandira chizindikiro cha pulse cha injini yowongolera mafuta, ndikuwongolera molondola kuchuluka kwa mafuta omwe amathiridwa ndi nthawi yomwe amathiridwa mafuta. Kagwiridwe kake ka atomization ndi mphamvu yoletsa kutsekeka kwa nozzle ndizofunikira kwambiri pakugwira ntchito kwake.
Mitundu yosiyanasiyana ya ma injector amafuta ndi makhalidwe awo
Injection ya intake manifold : Mafuta amalowetsedwa mu intake manifold kenako amalowa mu injini kudzera mu valavu. Ubwino wa njira iyi ndikuti valavu ndi yoyera, mtunda woyaka ndi wautali, ndipo sikophweka kupanga carbon deposit, koma injection ya mafuta si yolondola mokwanira, zomwe zingayambitse kuchuluka kwa mafuta ndi mphamvu zosakwanira .
Kulowetsa mwachindunji kwa silinda: Kulowetsa mwachindunji mafuta mu silinda, kulowetsa ndikolondola kwambiri, kumatha kusintha kugwiritsa ntchito mafuta, kuchepetsa kugwiritsa ntchito mafuta, kuwonjezera mphamvu, koma zofunikira pamtundu wa mafuta ndizokwera, kuthamanga kwa mafuta kumakweranso.
Malangizo okonza
Pofuna kuonetsetsa kuti nozzle ikugwira ntchito bwino, tikukulimbikitsani kuti muyang'ane ndikutsuka nozzle nthawi zonse kuti mupewe kutsekeka ndi kuipitsidwa. Kuphatikiza apo, malinga ndi momwe galimotoyo imagwiritsidwira ntchito komanso malangizo a wopanga, nthawi zonse sinthani unyolo wa nthawi ndi nozzle yamafuta kuti injini igwire bwino ntchito.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
