3975375 Pampu Yojambulira Mafuta ikwanira Magawo a Injini ya Cummins QSL9

Pali mitundu itatu ya mabwalo owongolera pampu yamafuta: dera loyang'anira pampu yoyendetsedwa ndi ECU, dera lowongolera pampu yamafuta, ndi dera lowongolera pampu yamafuta ndi liwiro.

1.ECU yolamulira pampu yamafuta ozungulira dera

(1) Pamene chowotcha choyatsira chimayatsidwa, pano ikuyenda kudzera pa koyilo yayikulu yolumikizirana, zolumikizira zimatsekedwa, ndipo magetsi amapereka mphamvu ku EFI.

(2) Injini ikayambika, cholumikizira choyambira (ST) cholumikizira cholumikizira chimalumikizidwa, ndipo koyilo L2 mumayendedwe opatsirana ozungulira imakhala ndi mphamvu, zomwe zimapangitsa kuyamwa kuti kutseke zolumikizirana ndi wodutsa dera.Mphamvu yamagetsi imaperekedwa ku mpope wamafuta, ndipo pampu yamafuta imayikidwa kuti igwire ntchito.

(3) Injini ikangoyambika, sensa yothamanga imalowetsa chizindikiro cha liwiro la injini Ne mu ECU.Panthawi imeneyi, transistor VT mu ECU ndi anatembenukira, ndi koyilo L1 mu dera wosweka cholandilira ndi mphamvu, kotero kuti kulankhula kupitiriza kukhala chatsekedwa, ndi mpope mafuta akupitiriza kugwira ntchito.

(4) Injini ikasiya kugwira ntchito, VT imachotsedwa, zolumikizira zolumikizira dera zimachotsedwa, chingwe chamagetsi cha pampu yamafuta chimasokonekera, ndipo pampu yamafuta imasiya kugwira ntchito.

2. Kusintha koyendetsedwa ndi mafuta oyendetsa magetsi

(1) Yatsani chosinthira choyatsira, zolumikizira zazikuluzikulu zimatsekedwa, ndipo magetsi amapereka mphamvu ku dongosolo la EFI.

(2) Poyambira, chosinthira choyatsira chimalumikizidwa ndi cholumikizira cha ST, cholumikizira cholumikizira dera L2 chimakhala ndi mphamvu, zolumikizira zolumikizirana zimatsekedwa, ndipo pampu yamafuta imayamba kugwira ntchito.

(3) Injini ikugwira ntchito, ndipo mpweya womwe umalowa mu injiniyo umayenda kudzera pa mita yoyendera mpweya.Mbale yoyezera mu mita yoyendetsa mpweya imazungulira, kuyatsa chosinthira pampu yamafuta, ndipo coil L1 ya cholumikizira chozungulira chimayamba kulimbikitsidwa.

3. Dongosolo lowongolera pampu yamafuta ndi kuwongolera liwiro

(1) Pamene injini ikugwira ntchito pa liwiro otsika kapena sing'anga katundu ang'onoang'ono, transistor mu ECU ndi anatembenukira, ndi koyilo ya mafuta mpope ulamuliro relay ndi mphamvu, kuchititsa kukhudzana B kutseka.Chifukwa cha chopinga chomwe chimayikidwa pamndandanda ndi dera, pampu yamafuta imagwira ntchito mwachangu.

(2) Pamene injini ikuyenda pa liwiro lalikulu ndi katundu wolemetsa, transistor mu ECU imadulidwa ndipo kukhudzana ndi A kutsekedwa.Pampu yamafuta imalumikizidwa mwachindunji ndi magetsi ndipo imathamanga kwambiri.
