Abstract

SISTEMA DE AVALIAÇÃO DE CONCENTRAÇÃO DE COMBUSTÍVEL ALTERNATIVO, VEÍCULO COMPREENDENDO SISTEMA DE AVALIAÇÃO DE CONCENTRAÇÃO DE COMBUSTÍVEL ALTERNATIVO E MÉTODO DE AVALIAÇÃO DE CONCENTRAÇÃO DE COMBUSTÍVEL ALTERNATIVO, uma ECU 60 é utilizada em uma motocicleta 1, incluindo um motor E que queima em uma câmara de combustão 23, um combustível misturado, no qual gasolina e etanol são misturados, e um dispositivo de injeção de combustível para injetar um combustível com um valor de injeção de combustível pré- determinado, de modo que uma taxa de excesso de ar na câmara de combustão 21 seja um primeiro valor pré-determinado quando uma concentração de etanol do combustível misturado for zero: a ECU 60 executa o controle de feedback de 02 com base em uma concentração de 02 derivada de uma produção de um sensor de 02: adicionalmente, a ECU 60 calcula uma taxa de compensação de combustível real pela divisão de um valor de injeção de combustível depois do controle de feedback de 02 por um valor de injeção de combustível pré- determinado, e avalia a concentração com base nesta taxa de compensação de combustível real e um primeiro valor pré-determinado armazenado na ECU 60.
