Abstract

UN MOTOR DE COMBUSTION INTERNA EN QUE CADA CILINDRO SE ENCUENTRA CONECTADO A UNAS FUENTES DE AIRE Y DE COMBUSTIBLE MANTENIDAS COMO GAS A PRESION Y EN QUE LA CARRERA DE COMPRESION, DURANTE LA CUAL UNA CARGA COMPLETA DE AIRE ES ARRASTRADA Y COMPRIMIDA, SE COMPLETA SUSTANCIALMENTE ANTES DE QUE LA CARGA DE COMBUSTIBLE SEA ADMITIDA Y LA MEZCLA SE QUEME PARA QUE SE INICIE LA CARRERA DE POTENCIA SUBSIGUIENTE. EL COMBUSTIBLE PUEDE SER ADMITIDO A TRAVES DE UNA UNIDAD QUE TIENE DOS FUNCIONES, UNA DE VALVULA DE ADMISION Y OTRA DE IGNITOR, Y LOS MOTORES CONVENCIONALES DE GASOLINA O DIESEL SE PUEDEN CONVERTIR SI SE DISEÑA ESA UNIDAD DE MODO QUE ENCAJE EN LOS ORIFICIOS DE LAS BUJIAS Y DE LOS INYECTORES. EL COMBUSTIBLE GASEOSO COMPRIMIDO PUEDE SER METANO O CUALQUIER OTRO GAS NATURAL. LA INVENCION SE REFIERE TAMBIEN A MOTORES MOVILES Y FIJOS, ESPECIALMENTE A MOTORES DE AUTOMOVILES, Y A LOS METODOS PARA SU PUESTA EN FUNCIONAMIENTO.
