Abstract

METODO DE CONTROLAR EL MOVIMIENTO DE CIERRE DE UNA VALVULA DE ESCAPE EN MOTORES DE COMBUSTION Y VALVULA CORRESPONDIENTE EN QUE EL FLUJO VOLUMETRICO DE ACEITE DE LA CAMARA DE TRABAJO DE UNA VALVULA DE ESCAPE ACCIONADA HIDRAULICAMENTE ES VARIADO EN DEPENDENCIA DEL ESTADO EN CARGA DEL MOTOR POR MEDIO DE UNO O MAS PASOS DE ESTRANGULAMIENTO FIJOS DETERMINADOS MECANICAMENTE Y/O POR MEDIO DE UN ELEMENTO AJUSTABLE DE ESTRANGULAMIENTO. ESTE ESTRANGULAMIENTO SIGNIFICA QUE PUEDE REGULARSE EL CIERRE DE LA VALVULA DE ESCAPE CON INDEPENDENCIA DEL PERFIL DE CORRIENTE ABAJO DE LA LEVA DE ESCAPE, SIGNIFICANDO ADEMAS QUE ES POSIBLE VARIAR LAS RELACIONES EFECTIVAS DE COMPRESION DE UN MOTOR EN MARCHA. ELLO PERMITE MANTENER UN SALTO OPTICMO ENTRE LA PRESION DE COMPRESION Y LA DE COMBUSTION EN CUALQUIER NIVEL DE CARGA DEL MOTOR Y AUMENTAR LA RELACION DE COMPRESION A CARGA BAJA Y PARCIAL.
