Abstract
"MOTOR DE COMBUSTãO INTERNA E PROCESSO PARA MONITORAR A INJEçãO DE AR SECUNDáRIO PARA DENTRO DO SISTEMA DE EXAUSTãO". Para apurar o caudal de ar secundário solicitado no alimentador, propõe-se apurar o aquecimento gerado pela compressão do ar secundário por meio de sensores de temperatura. Na medida em que o alimentador de ar secundário for gerado por uma turbina conectada em paralelo no circuito de admissão à válvula de estrangulamento, o valor de temperatura medido do compressor pode ser comparado com uma redução da temperatura do ar de admissão da turbina. Desse modo podem ser apuradas proposições seguras sobre o caudal de ar secundário solicitado através de sensores simples. Pode-se dispensar o uso de um sensor de massa de ar, cuja aquisição é mais cara e é sensível a sujeira.
