Abstract

método de sincronização de motor. um método para sincronizar um motor de combustão interna do tipo de 4 tempos, compreendendo ao menos um cilindro que compreende um pistão que se desloca entre um ponto morto superior e um centro de ponto morto inferior, o movimento do pistão acionando um eixo de manivelas e um eixo de cames, o método caracterizado pelo fato de que compreende as seguintes etapas: tantas hipóteses plausíveis quantos forem os dentes de referência presentes no alvo fixado ao eixo de manivelas em dois giros de eixo de manivela são determinadas, com relação à posição de um dois pontos mortos superiores do cilindro de referência no ciclo de motor no momento da partida, a partir da partida do eixo de manivelas, a passagem das bordas de referência de um alvo fixado ao eixo de manivelas e das bordas ascendentes e descendentes de um alvo fixado ao eixo de cames é detectada, cada alvo sendo associado a um detector para produzir sensores de posição para o eixo de manivelas e eixo de cames, em uma posição atual do eixo de manivelas a partir de sua partida, o posicionamento das bordas detectadas é usado para eliminar uma ou mais hipóteses feitas para a posição do ponto morto superior do cilindro no momento da partida, mediante comparação do posicionamento das bordas detectadas com um posicionamento das bordas correspondendo às hipóteses determinadas, e a sincronização é terminada quando todas as hipóteses exceto uma tiverem sido eliminadas. a invenção também se refere ao dispositivo associado.
