Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA FRENADO DE MOTOR CON UN MOTOR DE COMBUSTION INTERNA DE CUATRO TIEMPOS, QUE MUESTRA AL MENOS PARA CADA CILINDRO UNA VALVULA DE SALIDA CONECTADA A UN SISTEMA DE SALIDA, EN CUYO SISTEMA DE SALIDA SE MONTA UN DISPOSITIVO ESTRANGULADOR, QUE ES ACCIONABLE PARA FRENADO DEL MOTOR DE TAL MODO, QUE SE ESTRANGULA LA CORRIENTE DE GASES DE EXHAUSTACION Y SE GENERA POR MEDIO DEL DISPOSITIVO DE ESTRANGULACION UN AUMENTO DE LA PRESION EN EL GAS DE EXHAUSTACION, QUE PROVOCA UN RETORNO DE CORRIENTE DESPUES DE UNA ABERTURA INTERMEDIA DE LA VALVULA DE SALIDA EN EL ESPACIO DE COMBUSTION Y DURANTE EL TIEMPO DE COMPRESION QUE TIENE LUGAR A CONTINUACION ABASTECE LA VALVULA DE SALIDA PARCIALMENTE ABIERTA PARA UNA POTENCIA DE FRENADO DEL MOTOR ELEVADA. PARA EL CONTROL DE LA VALVULA DE SALIDA PARA ABERTURA INTERMEDIA EN EL FRENADO DE MOTOR LAS APLICACIONES HASTA AHORA CONOCIDAS SON RELATIVAMENTE COMPLICADAS, CARAS Y NECESITAN MECANISMOS COSTOSOS EN CUANTO AL ESPACIO. CON ESTOS MECANISMOS SE CONTROLA DE FORMA FORZADA LA ABERTURA INTERMEDIA DE LA VALVULA DE SALIDA HACIA EL EXTREMO DEL DESPLAZAMIENTO DE LA VALVULA DE SALIDA CONTROLADA POR LA LEVA, ACTUANDO MAS TARDE PERO DURANTE EL PERIODO DE COMPRESION. EL PROCEDIMIENTO DE ACUERDO CON LA INVENCION PUEDE SIMPLIFICARSE DE FORMA COMPARATIVA, TAMBIEN CON MECANISMOS A SER MONTADOS DE MANERA SENCILLA EN MOTORES PRESENTES CARACTERIZANDOSE DE TAL MODO, QUE EN EL FRENADO DEL MOTOR SE ACCIONA EN LA ABERTURA INTERMEDIA DE LA VALVULA DE SALIDA EL DISPOSITIVO DE ESTRANGULACION, QUE SE ENCUENTRA EN POSICION CORRESPONDIENTE DE ESTRANGULACION ORIGINANDO EL AUMENTO DE PRESION PREDOMINANTE EN EL GAS DE EXHAUSTACION, ESTANDO ENGRANADA SEGUN TECNICA DE CONTROL. DESPUES DE LA ABERTURA INTERMEDIA PARA EL CIERRE DE LA VALVULA DE SALIDA SE DISPONE DE UN EQUIPO DE CONTROL MONTADO EN EL MECANISMO DE ACCIONAMIENTO DE LA VALVULA DE SALIDA DE MANERA ALEJADA DE LA LEVA, EVITANDO EL CIERRE Y CON ELLO MANTENIENDO ABIERTO PARCIALMENTE EL DISPOSITIVO DE VALVULA DE SALIDA CONTROLADO CON LA LEVA.
