Abstract

"SISTEMA PARA DETECTAR O COMBUSTìVEL EVAPORADO PELO CARTER (BLOW-BY)". O qual tem por finalidade reconhecer o blow-by nos sistemas Flex, consubstanciando-se em um software de presença do vapor vindo do óleo do carter ('blow-by'), tendo por finalidade estimar a quantidade de combustível que se depositou durante a partida e funcionamento a frio do motor no carter e estimar também a quantidade que está evaporando do carter e entrando no coletor durante o funcionamento a quente do motor, e evitar erros ao reconhecer o combustível com que o veículo foi abastecido, a fim de garantir a este um funcionamento uniforme.
