Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA COMPROBACION DE LA CAPACIDAD FUNCIONAL DE UNA CALEFACCION ELECTRICA DE AUTOMOVILES, ESPECIALMENTE LA CALEFACCION DE UNA SONDA DE OXIGENO QUE ESTA DISPUESTA EN EL CANAL DE GAS DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA. PARA ENJUICIAR EXACTAMENTE EL ESTADO DE FUNCIONAMIENTO DE LA CALEFACCION DE LA SONDA DE OXIGENO, ES NECESARIO DETERMINAR LA RESISTENCIA ELECTRICA, DEPENDIENTE DE LA TEMPERATURA, Y LA TEMPERATURA DE LA CALEFACCION DE LA SONDA DE OXIGENO. EL PRINCIPIO FUNDAMENTAL DE LA INVENCION SE BASA EN QUE LA MEDICION DE LA RESISTENCIA ELECTRICA DE LA CALEFACCION DE LA SONDA DE OXIGENO SE PUEDE REALIZAR CUANDO LA CALEFACCION DE LA SONDA DE OXIGENO SE HA ENFRIADO A TEMPERATURA AMBIENTE. SE PUEDE DETERMINAR SI HA TENIDO LUGAR ESTE ENFRIAMIENTO, CONFORME AL EJEMPLO DE REALIZACION DE DIFERENTES MANERAS, POR EJEMPLO A PARTIR DEL ENFRIAMIENTO DEL BLOQUE MOTOR O POR COMPARACION DE LA TEMPERATURA DEL BLOQUE MOTOR CON LA TEMPERATURA AMBIENTE.
