Abstract

"UTILIZAçãO DE ADITIVOS DETERGENTES EM COMBUSTìVEIS COM ELEVADO TEOR DE ETANOL PARA CONTROLE DE DEPóSITOS". A presente invenção refere-se a um processo para controlar a formação de depósitos em válvulas de admissão enquanto que apresentando simultaneamente uma condição 'não prejudicial' de depósitos em câmaras de combustão em motores pela combustão, no motor, de uma composição combustível contendo um teor de etanol maior do que cerca de 5 % por volume e um aditivo de base Mannich. A invenção também se refere a um combustível com elevado teor de etanol contendo um detergente de base Mannich em uma quantidade efetiva para melhorar a redução de depósitos em válvulas de admissão resultantes da combustão do combustível em um motor."USE OF DETERGENT ADDITIVES IN HIGH ETHANOL FUELS FOR DEPOSIT CONTROL". The present invention relates to a process for controlling the formation of inlet valve deposits while at the same time presenting a 'non-detrimental' condition of combustion chamber deposits in engines by combustion in the engine of a fuel composition containing greater than about 5% by volume and a Mannich base additive. The invention also relates to a high ethanol fuel containing a Mannich base detergent in an amount effective to improve the reduction of intake valve deposits resulting from combustion of fuel in an engine.
