Abstract

SISTEMA E MéTODO DE IDENTIFICAçãO E DE AQUECIMENTO DE COMBUSTìVEL. A presente invenção refere-se a um sistema e a um método de identificação de combustível, normalmente aplicados a veículos a motores de combustão interna do tipo bi-combustivel, por meio dos quais é possível identificar qual a composição do combustível utilizado em cada momento, particularmente qual a proporção empregada em uma mistura de gasolina e etanol, por meio do mesmo dispositivo que realiza o aquecimento do combustível. O sistema de acordo com a invenção compreende um resistor (3) de aquecimento de combustível, com valor de resistência variável em função da sua temperatura, conectado a um circuito de alimentação que aplica uma tensão de alimentação sobre o resistor (3); um dispositivo de medição de corrente (6) que mede a corrente sobre o resistor variável (3); uma unidade eletrónica de controle (4) conectada ao resistor (3), que mede a tensão de alimentação aplicada ao resistor (3), a unidade eletrónica de controle (4) estando ainda conectada ao dispositivo de medição de corrente (6), e recebe deste os valores medidos de corrente do resistor (3); uma câmara (7) com um volume interno (8) predeterminado, possuindo uma entrada de fluxo de combustível (10), e uma saída de fluxo de combustível (9), a referida câmara alojando o resistor (3) de aquecimento de combustível e uma quantidade predeterminada de combustível a ser aquecido, sendo que o resistor fica disposto em contato direto e realiza troca de calor com o combustível; um contador de tempo que marca um tempo de evaporação do combustível no momento em que todo o combustível compreendido na câmara (7) evaporou; e meios de processamento de dados da unidade eletrónica de controle (4) que calculam a energia absorvida pelo combustível através da potência fornecida ao resistor durante o tempo de evaporação de todo o combustível compreendido na câmara (7), e identificam a composição do combustível com base na energia absorvida pelo combustível e no tempo de evaporação do combustível.
