Abstract
SISTEMA E MÉTODO DE IDENTIFICAÇçO DE COMBUSTÍVEL. 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 bicombustível, 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, ou ainda detectar a presença de combustível em forma de vapor na linha de combustível ou ar, por meio do mesmo dispositivo que realiza o aquecimento do combustível. O sistema de acordo com a invenção compreende um resistor de aquecimento (3) com valor de resistência variável em função da sua temperatura, sendo que o resistor fica disposto em contato com o combustível (2); um dispositivo de medição de corrente (6) que mede a corrente sobre o resistor variável (3); e uma unidade eletrônica de controle (4) conectada ao resistor (3), e conectada ao dispositivo de medição de corrente (6), recebendo deste os valores medidos de corrente do resistor (3), sendo que a unidade eletrônica de controle (4) compreende meios de processamento de dados, com o auxílio dos quais identifica propriedades do combustível (2) com base na corrente do resistor (3).
