Abstract
"PROCESSO DE COMBUSTãO COM GERAçãO REDUZIDA DE NO~ X~" Um processo de combustão de baixo teor de NO~ x~ é realizado por meio de reação de baixas concentrações de combustível com baixas concentrações de oxigênio. Estas baixas concentrações são obtidas pela injeção de correntes de oxidante e de combustível de elevada velocidade através das aberturas de porta espacialmente espaçadas.
