Abstract

Se describe un sistema de diagnóstico a bordo para detectar las condiciones del malfuncionamiento en un tren de válvulas hidráulicas de un motor MultiAirTM. El sistema comprende una pluralidad de sensores de presión (12a-n) para generar las señales de presión localizadas en un circuito hidráulico del tren de válvulas hidráulicas; y un módulo de control de motor (16) para realizar un análisis de forma de onda de las señales de presión para detectar las condiciones de malfuncionamiento en el tren de válvulas hidráulicas. El módulo de control de motor (16) realiza un análisis frecuencia y/o de tiempo de retraso de la forma de onda.
