Abstract

UN MOTOR DE COMBUSTION INTERNA DE ENCENDIDO POR BUJIAS DE CICLO DE DOS MOVIMIENTOS OPERA CON UNA VALVULA DE DESCARGA (21) CONTROLADA INDEPENDIENTEMENTE DE LA POSICION DEL CIGUEÑAL (11) Y OPTIMAMENTE PARA ALTA TENSION Y SALIDA DE BAJO NIVEL DE POLUCION COMBINADA CON UNA BOMBA DE EXPULSION (33) Y CON UN INYECTOR DE COMBUSTIBLE (30). EL VOLUMEN DE LA MEZCLA COMBUSTIBLE SE ESTABLECE EN EL PUNTO EN EL CICLO EN QUE LA VALVULA DE DESCARGA ESTA SELECCIONADAMENTE CERRADA CON EL PISTON (17) MOVIENDOSE HACIA ARRIBA Y DECRECIENDO EL VOLUMEN DEL CILINDRO. SE ELIMINAN LAS PERDIDAS DE REGULACION YA QUE EL PISTON FUERZA EL AIRE DE DESCARGA FUERA DEL CILINDRO A TRAVES DE UNA VALVULA DE DESCARGA COMPLETAMENTE ABIERTA (21) EN LUGAR DE QUE EL AIRE ATRAIDO HACIA EL CILINDRO COMPARADO CON LA PRESION REDUCIDA CAUSADA POR UN PLATO REGULADOR PARCIALMENTE CERRADO. EL VOLUMEN DEL AIRE COMBUSTIBLE EN EL CILINDRO SE DETERMINA POR EL PUNTO EN EL CICLO EN EL QUE LA VALVULA DE DESCARGA (21) SE CIERRA Y UNA CARGA APROPIADADE COMBUSTIBLE SE INYECTA POSTERIORMENTE AL CILINDRO.
