Abstract

Patente de Invenção: <B>"SISTEMA DE INJEçãO DE COMBUSTìVEL AUXILIADO A AR COMPRIMIDO"<D>. A presente invenção trata de um motor de combustão interna dotado de um sistema de injeção de combustível auxiliado a ar comprimido (20). O sistema de injeção é dotado de um acumulador de ar comprimido (34) com uma primeira abertura (30) dentro do cilindro e o motor e a segunda abertura (38) dentro da caixa de manivela (18) do motor. As duas aberturas são localizadas em extremidades opostas do acumulador e o acumulador é dotado de um formato tubular. O acumulador ventila a pressão a cada momento em que um dos orifícios dentro do cilindro é fechado. O formato do tubo acumulador forma um tubo de reflexão sintonizado por uma onda de compressão a partir do cilindro para gerar uma onda de compressão refletida para ajudar no envio de combustível e ar para dentro do cilindro. As duas aberturas são adaptadas para serem abertas e fechadas pelo cabeçote de pistão do motor.
