Abstract

UN METODO PARA RETARDAR UN MOTOR CON UN MOTOR DE COMBUSTION DE MULTIPLES CILINDROS, QUE PARA CADA CILINDRO CON SU PISTON CORRESPONDIENTE, TIENE UNA VALVULA DE ESCAPE PARA CONTROLAR LA CONEXION ENTRE UNA CAMARA DE COMBUSTION (4) QUE HAY EN EL CILINDRO Y UN SISTEMA DE ESCAPE. LA ABERTURA DE LA VALVULA DE ESCAPE PARA RETARDAR EL MOTOR SE CONSIGUE REGULANDO UNA SEPARACION QUE HAY EN EL MECANISMO DE VALVULAS DEL MOTOR Y ACOPLANDO ASI UNO O MAS RESALTES DE LEVA ADICIONALES (38) QUE HAY EN EL ARBOL DE LEVAS DEL MOTOR (10), LO QUE ACTIVA DE FORMA CONTINUA EL MECANISMO DE VALVULAS DEPENDIENDO DE LA POSICION MOMENTANEA DEL ARBOL DE LEVAS DEL MOTOR, UTILIZANDO UN DISPOSITIVO DE REGULACION DEL ESPACIO, ACCIONADO HIDRAULICAMENTE Y AJUSTABLE DE FORMA ACTIVA (16). PARA EL CONTROL ACTIVO DEL RETARDO DEL MOTOR DICHO DISPOSITIVO SE PUEDE AJUSTAR ENTRE DIFERENTES POSICIONES MEDIANTE UNA PRESION DE FLUIDO HIDRAULICA INFERIOR A UN VALOR MAXIMO CONTROLADO POR UNA VALVULA DE ALIVIO DE LA PRESION (25). LA POSICIONANGULAR DEL ARBOL DE LEVAS, EN LA QUE LAS VALVULAS DE ESCAPE SON ACCIONADAS POR DICHO O DICHOS RESALTES DE LEVA ADICIONALES DEPENDE DE LA SEPARACION MOMENTANEA DEL MECANISMO DE VALVULAS. LA SEPARACION SE PONE GRADUALMENTE A CERO O SE CIERRA A CERO CUANDO LA PRESION DEL DISPOSITIVO REGULADOR DE LA SEPARACION CORRESPONDIENTE (16) SE LIMITA A UN CIERTO VALOR PREDETERMINADO. INDEPENDIENTEMENTE DEL MOMENTO EN EL SE INICIA O TERMINA EL RETARDO DEL MOTOR DURANTE EL CICLO DE TRABAJO DE LOS CILINDROS, EL RIESGO DE ABERTURA, DEBIDO AL ESFUERZO, POR A UNA PRESION DEMASIADO ELEVADA DEL CILINDRO QUEDA ASI ELIMINADO.
