Abstract

LA INVENCION SE REFIERE A UN SISTEMA Y DISPOSITIVO DE FRENADO DE UN MOTOR DE COMBUSTION INTERNA DE CUATRO TIEMPOS. EL MOTOR TIENE POR CADA CILINDRO (2), UNA VALVULA DE ADMISION (7) Y UNA VALVULA DE ESCAPE (9) QUE CONTROLA LA COMUNICACION ENTRE LA CAMARA DE COMBUSTION (5) EN EL CILINDRO (2) Y EL SISTEMA DE ADMISION (8) Y EL SISTEMA DE ESCAPE (10) RESPECTIVAMENTE. CONFORME CON LA INVENCION, EL FISPOSITI O COMPRENDE TAMBIEN MEDIOS PARA ESTABLECER COMUNICACION ENTRE LA CAMARA DE COMBUSTION (5), Y EL SISTEMA DE ESCAPE (10) EN CONJUNCION CON EL GOLPE DE ESCAPE Y TAMBIEN CUANDO EL PISTON (3), SE ENCUENTRA EN POSICION DE APROXIMIDAD DE SU PUNTO MUERTO, DESPUES DEL GOLPE DE ADMISION Y DURANTE LA ULTIMA FASE DEL MOVIMIENTO DE EXPANSION. LA COMUNICACION DE LA CAMARA DE COMBUSTION (5) CON EL SISTEMA DE ESCAPE (10), SE EFECTUA DURANTE EL RECORRIDO DEL MECANISMO DE ESTRANGULAMIENTO (13) DISPUESTO EN EL SISTEMA DE ESCAPE. ESTE ESTRANGULADOR, OPERA COMO REGULADOR DE AL MENOS UNA PARTE DEL FLUJO A TRAVES DEL SISTEMA DE ESCAPE (10) DURANTE LA OPERACION DE FRENADO DEL MOTOR, CON LO QUE AUMENTA A PRESION DEL RECORRIDO HACIA ARRIBA DEL MECANISMO DE ESTRANGULAMIENTO (13).
