Abstract

LA UNIDAD DE CONTROL INCLUYE UN DETECTOR (7) QUE PROPORCIONA UNA SEÑAL INDICATIVA DEL FLUJO DE CORRIENTE EN LAS BUJIAS (2) DE PRECALENTAMIENTO, Y CIRCUITOS DE DIFERENCIACION (9) QUE GENERAN SEÑALES INDICATIVAS DEL DIFERENCIAL DE TIEMPOS DE LA INTENSIDAD DE LA CORRIENTE. LA CORRIENTE EN LAS BUJIAS DE PRECALENTAMIENTO (2) SE DESCONECTA CUANDO EL DIFERENCIAL DE TIEMPOS DE LA INTENSIDAD DE LA CORRIENTE QUE PASA A TRAVES DE ELLAS CAE POR DEBAJO DE UN VALOR DE UMBRAL PREVIAMENTE DETERMINDO.
