Kutsegula kwa valve yoletsa kupanikizika kumagawidwa m'zigawo ziwiri: kutsegula mwakhama ndi

kutsegula chabe.

Kutsegula mwachangu

Mukalandira zidziwitso zolakwika kuchokera kuzinthu zina zofananira, injini yamagetsi yamagetsi (ECU) ipanga njira yodzitetezera ndikulangiza valavu yoletsa kuthamanga kuti atsegule (ngakhale kuthamanga kwa njanji sikuli kokwera kwambiri), potero kupewa kulephera kwakukulu kwa injini.Ndi zidziwitso ziti zomwe zingapangitse ECU kuchita njira yodzitetezera?

1. Chizindikiro cha sensa ya njanji

Pamene njanji yothamanga njanji imatumiza chizindikiro cha njanji chopitirira malire ku ECU, kaya ndi yokwera kwambiri kapena yotsika kwambiri, idzachititsa ECU kuchita njira yotetezera ndikutsegula valve yolepheretsa.Pali zifukwa zambiri zomwe sensor pressure sensor ikunena za vuto.Chofunikira chake ndi kukakamiza kolowera kwamafuta kapena kuthamangitsidwa kwamafuta, monga kusakwanira kwamafuta pamzere wocheperako wamafuta, kuvala pampu yothamanga kwambiri, kusasindikiza bwino kwa valve yoletsa kupanikizika, komanso kuchuluka kwamafuta ochulukirapo kuchokera ku jekeseni. .Mzere wa mafuta watsekedwa, etc.

2. Chizindikiro cha kulephera kwa valve metering yamafuta

Pofuna kukonza bwino, pampu yothamanga kwambiri ya njanji wamba imakhala ndi metering unit yowongolera kuchuluka kwamafuta, valavu yamagetsi yamafuta.Imawongolera kuthamanga kwamafuta mu njanji yothamanga kwambiri powongolera kuchuluka kwa mafuta omwe amalowa mu mpope wothamanga kwambiri.ECU imayang'anira gawo la metering posintha kayendetsedwe ka ntchito mkati mwa metering unit kudzera pa ma pulse sign.Pamene valavu ya metering ikulephera, zikutanthauza kuti ECU sichitha kulamulira molondola kuthamanga kwa njanji.Choncho, ikalandira chidziwitso cholakwika chokhudzana ndi valavu ya metering, monga chigawo chachifupi, cholakwika chotseguka, kapena kutentha kwachilendo, ECU idzagwiritsa ntchito njira yotetezera kuchepetsa Valavu yothamanga idzatsegulidwanso.

3. Sensor power supply module 3 chizindikiro cholakwika

Sensor power supply module 3 imapereka mphamvu ya 5V kwa masensa angapo, kuphatikizapo masensa a njanji.Pamene gawo la 3 la sensor power supply likulephera, zikutanthauza kuti masensa onse omwe ali nawo amatha kugwira ntchito molakwika.Choncho, ECU ikalandira chidziwitso cholakwika chokhudzana ndi 3 sensor power supply module, idzagwiritsa ntchito njira yotetezera ndipo valve yochepetsera mphamvu idzatsegulidwa.

4. Zolakwika zokhudzana ndi ECU

Monga mtsogoleri wamkulu wa njanji wamba, zotsatira za kulephera kwa ECU zikhoza kuganiziridwa.Choncho, pamene dongosololi lizindikira zolakwika zokhudzana ndi ECU, lidzagwiritsanso ntchito njira yotetezera.

Kutsegula mosadukiza

Zifukwa zodziwika zomwe zimatsegulira mosadukiza ndi izi: valavu ya metering yamafuta kapena kulephera kwa ma valve opumira, kulephera kwa pampu yothamanga kwambiri, kuwonongeka kwa sensor ya njanji komwe kumapangitsa kuti njanji isayende bwino, kutsekeka kwa mapaipi obwerera, ndi zina zambiri.
