Abstract

La presente solicitud se refiere a un sistema en un motor de combustion interna (CI), que comprende un accionador (6), una unidad generadora de pulsos (3) y un controlador de arranque. El accionador (6) rota en conjunto con el cigüenal del motor de CI y comprende por lo menos dos bordes anteriores consecutivos (LE1, LE2) y por lo menos un borde posterior (TE1). La unidad generadora de pulsos (3), accionada por los bordes (LE1, LE2, TE1) del accionador (6) que pasan por debajo de la unidad generadora de pulsos (3) ante la rotacion del cigüenal, genera una secuencia de pulsos. Los pulsos son indicativos de un ángulo del cigüenal. El controlador de arranque genera una chispa para encender el combustible en el motor de CI en base a la secuencia de pulsos y la velocidad del cigüenal.The present application refers to a system in an internal combustion engine (CI), comprising an actuator (6), a pulse generating unit (3) and a starter controller. The actuator (6) rotates in conjunction with the CI engine crankshaft and comprises at least two consecutive leading edges (LE1, LE2) and at least one trailing edge (TE1). The pulse generating unit (3), driven by the edges (LE1, LE2, TE1) of the actuator (6) that pass below the pulse generating unit (3) before the crankshaft rotation, generates a pulse sequence. The pulses are indicative of an angle of the crankshaft. The starter controller generates a spark to ignite the fuel in the IC engine based on the pulse sequence and the crankshaft speed.
