Momwe mungasinthire EVP shutdown solenoid

Valavu ya EGR ndiyofunikira pa dongosolo la EGR mugalimoto yanu. Kuti valavu iyi igwire ntchito, EVP shutdown solenoid iyenera kuyang'anira malo ndi ntchito yake.

Makampani opanga magalimoto akhala akukumana ndi mikangano, makamaka pamene akuyesera kugwirizanitsa teknoloji yamakono mu zigawo zakale. Mwachitsanzo, koyambirira mpaka pakati pa zaka za m’ma 1990, opanga magalimoto ambiri anayamba kuchoka pamakina oyendetsedwa ndi makina kupita kumakompyuta ndi makompyuta. Chitsanzo cha izi chinali chakuti makina akale othamangitsidwa ndi vacuum EGR adasinthidwa pang'onopang'ono mpaka adayendetsedwa bwino ndi makompyuta. Izi zidapanga mtundu wosakanizidwa wadongosolo la EGR ndipo magawo adapangidwa kuti afulumizitse kutembenukaku. Chimodzi mwa zigawozi chimadziwika kuti EVP shutdown solenoid kapena EGR valve position solenoid ndipo idagwiritsidwa ntchito m'magalimoto, magalimoto ndi ma SUV ogulitsidwa ku US kuyambira 1991 mpaka kumayambiriro kwa zaka za m'ma 2000.

Choyambitsidwa mu 1966 pofuna kuchepetsa mpweya wagalimoto, dongosolo la EGR lapangidwa kuti ligawitsenso mpweya wotulutsa mpweya wokhala ndi mafuta osawotchedwa (kapena mpweya wagalimoto) m'malo ochulukirapo, pomwe amawotchedwa pakuyaka. Popatsa mamolekyu amafuta omwe sanawotchedwe mwayi wachiwiri wowotcha, mpweya wotuluka m'galimoto umachepetsedwa ndipo mafuta amafuta nthawi zambiri amakhala bwino.
