Abstract

MéTODO PARA ESTIMAR A POSIçãO ANGULAR DO VIRABREQUIM NA QUAL 50% DA MASSA DE COMBUSTìVEL FOI QUEIMADA EM UM CILINDRO DE UM MOTOR DE COMBUSTãO INTERNA COM IGNIçãO ESPONTáNEA DA MISTURA. Trata-se de um método de estimação do ângulo do virabrequim no qual 50% da massa de combustível foi queimada em um cilindro (2) de um motor de combustão interna (1) com ignição espontânea da mistura, provido de um eixo de acionamento (4) acoplado a uma roda fónica (5) apresentando uma série N de dentes (6); o método compreendendo as etapas de: ler a passagem de cada dente (6) da roda fónica (5) diante de um sensor (7); determinar a velocidade angular (<sym>~ i~) do eixo de acionamento (4) em cada evento de dente da roda tónica (5); determinar pelo menos um harmónico (<87>~ n~ do sinal de velocidade; determinar um modelo mecânico inverso (H(j<sym> = T / <87>) da transmissão; determinar pelo menos um harmónico de torque (T~ n~) aplicando o modelo mecânico inverso (H(j<sym>) = T / <87>) ao harmónico do sinal de velocidade (<87>~ n~); determinar uma função algébrica (<sym>) que coloca Lim índice de combustão (MFB5O) em relação com a fase (Arg(T~ n~)) do n-ésimo harmónico de torque (T~ n~); e determinar o índice de combustão (MFB5O) aplicando a primeira função algébrica (<sym>) ao n-ésimo harmónico de torciLie (T~ n~).
