Abstract

MéTODO PARA A DETECçãO DO PONTO DE IGNIçãO DE UM MOTOR à COMBUSTãO A presente invenção refere-se a um método de detecção do ponto de ignição de um motor à combustão (1) com vários cilindors (2,3,4,5), mediante um sinal taquimétrico de rotação determinado para um eixo (6) do motor à combustão(1). A partir do sinal taquimétrico de rotação é extraído um sinal de segmento (SS), com um comprimento de sinal correspondente a uma revolução completa do eixo (6). A partir do sinal de segmento (SS) é gerado um sinal de cilindro (ZS1,ZS2,ZS3,ZS4) que preproduz o estado de funcionamento de um dos cilindros (2,3,4,5). O sinal de cilindro (ZS1,ZS2,ZS3,ZS4) é transformado em um sinal de freqüencia de cilindro (FS1,FS2,FS3,FS4) no domínio da freqüencia angular. A partir do sinal de freqüencia de cilindro (FS1,FS2,FS3,FS4) é extraída a informação de sinal para o ponto de ignição do cilindro correspondente (2,3,4,5) em pelo menos uma freqüencia angular predeterminada.
