Abstract

um dispositivo para detectar e monitorar a velocidade de rotação do eixo de manivela e a sua posição em um motor de quatro tempos, no qual um primeiro e um segundo sensores (3, 4) são dispostos para detectar passagem de marcas de referência (9, 9´) em elemento ou elementos rotativos (1, 1´). o primeiro sensor (3) é um sensor de alta precisão que é disposto para detectar passagem de marcas de referência (9) sobre um volante do eixo de manivela (1) do motor, e o segundo sensor (4) é um sensor de baixa velocidade que é disposto para detectar passagem de marcas de referência (9, 9´) sobre o volante do eixo de manivela (1) ou marcas de referência ou uma roda (1') que é associada a um eixo de came do motor. a invenção também é relativa a um método e a um veículo.
