Abstract

CARBURADOR COM REGULAÇçO MECÂNICA DE RAZçO AR-COMBUSTÍVEL COM REGULAÇçO DE PRESSçO DE COMBUSTÍVEL. É descrito um carburador (8) que compreende uma entrada de ar (2) com uma válvula mecanicamente ajustável (3), um atomizador mecanicamente ajustável inserido na entrada de ar e um dispositivo de medição mecânico conectado com a válvula de ar e o atomizador, que mantém uma razão estequiométrica entre as proporções de ar e combustível. Além disto, o carburador tem elementos/dispositivos reguladores da pressão do combustível (13) que são equipados para influir na pressão do combustível, dependendo de um ou mais parâmetros de carga dinâmica do motor, de acordo com os quais o sinal de vácuo na entrada de ar é obtido por meio de um conduto de admissão de vácuo (12) introduzido na entrada de ar (2). Pela regulação da pressão do combustível, que depende também do sinal de vácuo medido, a emissão de combustível não queimado é reduzida em determinadas condições dinâmicas do motor de combustão.
