Abstract

Un mecanismo variable de característica de válvula M de un dispositivo de funcionamiento de válvula 40 cambia un período de superposicion y un período sin superposicion para, de esta manera, controlar el caudal de recirculacion interna de gases de escape. El mecanismo variable de características de válvula M comprende un mecanismo de control M3 para hacer oscilar el mecanismo de union de admision conectado a una leva de admision 53 y un mecanismo de union de escape conectado a una leva de escape 54 alrededor de un eje de distribucion 50, y un mecanismo motriz para accionar el mecanismo de control M3. El mecanismo de control M3 conecta el mecanismo motriz con los respectivos mecanismos de union, de manera tal que el nivel de retraso en el tiempo de apertura de la válvula de admision 22 mediante el mecanismo de union de entrada es mayor que el nivel de avance del tiempo de cierre de la válvula de escape 23 mediante un mecanismo de union de escape cuando se asume el mismo nivel de accionamiento del mecanismo motriz en una direccion donde aumente el caudal de recirculacion interna de gases de escape.A variable valve characteristic mechanism M of a valve operating device 40 changes an overlapping period and an overlapping period to thereby control the internal recirculation flow of exhaust gases. The variable valve feature mechanism M comprises a control mechanism M3 for oscillating the intake joint mechanism connected to an intake cam 53 and an exhaust joint mechanism connected to an exhaust cam 54 about a distribution shaft 50, and a driving mechanism for operating the control mechanism M3. The control mechanism M3 connects the drive mechanism with the respective joint mechanisms, such that the level of delay in the opening time of the intake valve 22 through the inlet joint mechanism is greater than the level of advance of the closing time of the exhaust valve 23 by means of an exhaust union mechanism when the same level of actuation of the driving mechanism is assumed in a direction where the internal recirculation flow of exhaust gases increases.
