Abstract

Patente de Invenção:<B>"PROCESSO PARA A DETERMINAçãO DA TEMPERATURA DOS GASES DE ESCAPAMENTO E DO NúMERO LAMBDA DE PROPORçãO AR/COMBUSTìVEL, E DISPOSIçãO DO SENSOR PARA A REALIZAçãO DO PROCESSO"<D>. Para a determinação da temperatura dos gases de escapamento e da proporção ar/combustível, <sym>, utiliza-se - de acordo com o estado da técnica via de regra, dois elementos sensores separados ou, então, efetua-se a medição da temperatura e do <sym> pelo menos a uma temperatura inferior a 250°C, de uma maneira não-simultânea. Além disso, a medição simultânea dotada de suficiente precisão só é possível com funcionamento estacionário. O processo de acordo com a invenção e o dispositivo de sensor apropriado permitem agora realizar-se uma medição precisa de temperatura e de <sym> com pouco dispêndio de técnicas de medição, principalmente também no caso de operação estacionária, efetuando-se a medição da temperatura dos gases de escapamento com um sensor aquecível que apresenta um elemento sensível à temperatura e um elemento sensível ao oxigênio, mesmos à temperaturas mais baixas, com aquecimento desligado e apenas na faixa de temperaturas mais baixas, com aquecimento desligado e apenas na faixa de temperatura superior, simultaneamente com a determinação do <sym>
