Abstract
FUNCION DE CALENTAMIENTO PARA CATALIZADORES PARA LA REDUCCION DE LA EMISION DE COMPONENTES DE GAS DE ESCAPE NOCIVOS, CON CUYA AYUDA SE PUEDEN TOMAR MEDIDAS PARA EL CALENTAMIENTO ACELERADO DEL CATALIZADOR CUANDO YA ESTA CALIENTE EL MOTOR DE COMBUSTION INTERNA, POR EJEMPLO DESPUES DE UN ARRANQUE EN CALIENTE. DE ESTE MODO SE CONTRARRESTA EL ENFRIAMIENTO DEL MOTOR DE COMBUSTION INTERNA Y DEL CATALIZADOR QUE SE EFECTUA CON MUCHA DIFERENCIA AL HABER UNA INTERRUPCION DE SERVICIO, Y EL PERJUICIO VINCULADO CON ESTO DEL GRADO DE CONVERSION DEL CATALIZADOR. COMO CONSECUENCIA DE ESTE SE REDUCE LA EMISION DE COMPONENTES DE GAS DE ESCAPE NOCIVOS DESPUES DE UN ARRANQUE EN CALIENTE.
