Abstract

METODO PARA LLEVAR A CABO LA MEDIDA DE UNA CORRIENTE IONICA EN UN MOTOR DE COMBUSTION INTERNA UTILIZANDO UNA MEZCLA POBRE DE COMBUSTIBLE QUE REQUIERE UN INCREMENTO EN LA DURACION DE LA COMBUSTION, EN EL QUE SE DETECTA EL INICIO DE LA COMBUSTION O EL INICIO FALLIDO DE LA COMBUSTION, TRAS LO CUAL SE DESCONECTA LA BUJIA DE IGNICION Y SE PUEDE REALIZAR LA MEDIDA DE LA CORRIENTE IONICA. EL INICIO DE LA COMBUSTION PUEDE DETECTARSE POR MEDIO DE LA MEDIDA DEL CAMBIO EN LA TENSION DE ENCENDIDO Y/O LA CORRIENTE DE ENCENDIDO DETECTADA EN EL LADO DE BAJA TENSION DE LA BOBINA SECUNDARIA DEL SISTEMA DE IGNICION POR MEDIO DE CONDENSADORES DE FUGA DE LA BOBINA DE IGNICION, O POR MEDIO DE UN DEVANADO SEPARADO DE LA BOBINA DE IGNICION. LA BUJIA DE IGNICION SE DESCONECTA POR MEDIO DE UNA MAGNETO DE IGNICION CONTROLABLE.
