Abstract

MéTODOS PARA REDUZIR EMISSõES DE MATéRIA EM PARTìCULA DE EXAUSTãO DE MOTOR DIESEL EMPREGANDO MISTURAS DE COMBUSTìVEL DE ETANOL/DIESEL EM MISTURA COM CATALISADORES DE OXIDAçãO DIESEL. Progresso considerável tem sido feito nos últimos anos a redução de emissões de exaustão tóxica de motores diesel. Os catalisadores de oxidação de diesel, por exemplo, estão encontrando uso crescente na redução de monóxido de carbono, hidrocarbonetos e na fração e na tração orgânica solúvel de material em partícula em tais emissões. As inovações recentes nos aditivos de estabilização de tensoativo agora possibilitam o etanol ser combinado com o combustível de diesel em soluções claras estáveis Na combustão, os combustíveis de etanol/diesel geram emissões menos tóxicas do que o diesel base, porém surpreendetemente quando empregado em conjunto com os catalisadores de oxidação de diesel, o material em partícula especialmente é dramaticamente reduzido. A eficácia de um catalisador de oxidação de diesel ligado a um exaustão de motor diesel é inesperadamente realçada pela presença de etanol no combustível diesel.
