Abstract

a presente invenção refere-se a um método para a identificação combinada de uma diferença de fase do curso do pistão, de uma diferença de fase da válvula de entrada e de uma diferença de fase da válvula da saída de um cilindro de um motor de combustão interna, em que as oscilações da pressão dinâmica, atribuíveis ao cilindro, do ar de entrada no trecho de entrada de ar e/ou do gás de exaustão no trecho de saída do gás de exaustão são medidas durante a operação e em que, com base na posição da fase das frequências de sinal selecionadas das oscilações da pressão medidas, linhas de posições de fase iguais são determinadas e, por meio da projeção e troca de fase, são colocadas em um ponto comum de interseção, a partir do que a diferença de fase do curso da válvula de entrada e a diferença de fase do curso da válvula de saída e a diferença de fase do curso do pistão são determinadas. dessa maneira, é possível efetuar a identificação particularmente exata dos sincronismos de controle de uma maneira simples e barata, por meio do que é possível obter vantagens no que diz respeito às emissões, ao consumo, à suavidade de operação e à potência, e uma melhoria na regularidade e controle do motor pode ser obtida.
