Abstract

"DISPOSITIVO PARA RETORNO DE GáS DE ESCAPE EM UM MOTOR DE COMBUSTãO INTERNA", no qual uma quantidade predefinível de gás de escape recirculado é introduzido no canal de admissão de um motor de combustão interna, na direção de fluxo e por trás de uma válvula de estrangulamento (2). A válvula (8), por exemplo uma válvula pulsada, é inserida no circuito de recirculação de gás de escape (5), permitindo a passagem de gás de escape ou ar fresco em uma relação de pulso e quantidade predeterminados, produzindo, deste modo, uma mistura de ar/gás de escape para ser injetada no canal de admissão do motor.
