Abstract

"SISTEMA DE CONTROLE DE EMISSõES EVAPORATIVAS INCLUINDO UMA CAIXA DE CARVãO VEGETAL PARA PEQUENOS MOTORES DE COMBUSTãO INTERNA". A presente invenção refere-se a um sistema de controle de emissões evaporativas para pequenos motores de combustão interna, incluindo uma caixa de carvão vegetal que está em comunicação fluida com o espaço de ar acima do combustível líquido dentro do carburador do motor e do espaço de ar acima do combustível líquido dentro do tanque de combustível do motor. A caixa de carvão vegetal contém meios de carvão vegetal, e quando o motor não está operando, os vapores de combustível do carburador e do tanque de combustível migram para, e são capturados dentro, dos meios de carvão vegetal da caixa de carvão vegetal. A caixa de carvão vegetal pode compreender um componente separado, ou pode ser integralmente formada com um componente de motor tal como o purificador de ar, o carburador, ou o corpo do tanque de combustível, por exemplo. Durante a operação do motor, o vácuo dentro do carburador induz um fluxo de ar atmosférico através da caixa de carvão vegetal para purgar os vapores de combustível coletados dos meios de carvão vegetal, e os vapores de combustível passam para o motor para consumo. Em uma outra modalidade, um sistema de controle de emissões evaporativas incluindo uma caixa de carvão vegetal é fornecido para um motor que inclui um sistema de injeção de combustível.
