Kodi mpweya wa tanki yamafuta umagwira ntchito bwanji?
Mpweya wamafuta womwe umapangidwa mu thanki sungathe kuthawa. Imayendetsedwa ndi wowongolera mpweya wa tanki yamafuta.
Mpweya wamafuta wowononga chilengedwe umatulutsidwa mu thanki kupita mumtsuko wa kaboni, womwe umawatengera. Kuchokera pamenepo, mu mawonekedwe amadzimadzi, amalowetsamo zambirimbiri. Mpweya umaperekedwa ku vapor vapor adsorber kuti amasule kaboni kuchokera kumafuta omwe amasonkhanamo. Kupanikizika koyipa komwe kunapangidwa kumayamwa mafuta kuchokera ku malasha. Pakati pa canister ndi manifold manifold mumzere woperekera pali mafuta owongolera mpweya wa solenoid valve. Pamene injini ikugwira ntchito, wolamulira amatumiza zikhumbo zina kwa izo, zomwe mosiyanasiyana zimakhudza mlingo wa kutsegula kwa valve, zomwe zimatanthawuza kuchuluka kwa mpweya ndi mafuta omwe amayamwa mu malasha.
Vavu imakhalabe yotsekedwa injini ikayamba. Imatsegulidwa kokha pamene galimoto yoyendetsa galimoto yafika pa kutentha kwina kwa ntchito. Kutsegula kwa valve ya periodic ndi nthawi yotsegula kumatsimikiziridwa ndi wolamulira potengera zizindikiro monga kuchokera ku throttle position sensor ndi lambda probe. Kuwongolera valavu kumatanthawuza zomwe zimatchedwa machitidwe osinthika, zomwe zikutanthauza kuti chipangizo chowongolera chimasintha ma valve otsegula ndi kutseka kuzungulira kusintha kwa injini.
EOBD on-board diagnostic system imayang'ana magwiridwe antchito a tanki yamafuta mpweya wabwino. Mu kuyesa kwa capacitive, kutsegula valavu, malingana ndi kuchuluka kwa kudzazidwa kwa canister ndi mpweya wamafuta, kumasintha mawonekedwe a osakaniza. Kusintha kumeneku kwa kafukufuku wa lambda kumtunda kwa chosinthira chothandizira kumatsimikizira kuti mpweya wa tanki yamafuta ukugwira ntchito. Komanso, pa zomwe zimatchedwa B kuyesa kusinthasintha, injini yoyang'anira injini imatsegula ndikutseka pang'ono valavu, chifukwa chake kusintha kumachitika, i.e. kutengera kusinthasintha kwamphamvu kosiyanasiyana. Imayesedwa ndi sensor yokakamiza ndipo pamaziko a izi, gawo loyang'anira injini limayesa mphamvu ya mpweya wabwino wa thanki.
