Abstract

Un motor de combustion interno tiene enlaces hidráulicos controladas eléctricamente (64) entre las levas del motor (40) y las válvulas de cilindro del motor (30). Se desea omitir una saliente de leva (42a, 42b, 42c), o modificar la respuesta de una válvula de cilindro del motor a una saliente de leva (42a, 42b, 42c) el fluido hidráulico es selectivamente liberado desde el enlace hidráulico asociado (64) para permitir el movimiento perdido entre la leva (40) la válvula de cilindro de motor (30). Las válvulas del fluido hidráulico controladas eléctricamente (100) se usan para producir la liberacion selectiva del fluido hidráulico desde los enlaces hidráulicos (64). El modo de operacion del motor puede cambiarse (por ejemplo del modo de energía positiva al modo de frenado del motor de liberacion de compresion o viceversa), o pueden hacerse cambios más sutiles para modificar la regulacion y/o la duracion de las aberturas de válvula de motor para optimizar el rendimiento del motor para varias condiciones de operacion del motor o del vehículo (por ejemplo, diferentes velocidades del motor y del vehículo).
