  • Mechanically controllable valve train assembly, internal combustion engine and method for operating an internal combustion engine
    Patent number: 9157381
    Abstract: A valve train assembly for an engine comprising cylinders, each comprising a gas inlet and a gas outlet valve. A camshaft comprises a peripheral contour. A valve stroke adjusting device comprises a control shaft comprising control contours. An intermediate lever arrangement comprises an intermediate lever comprising a working curve which cooperates with a swivel lever, and an engagement element connected to a control contour. Each intermediate lever is connected to the peripheral contour. A transmission arrangement provides that an intermediate lever arrangement and a swivel lever arrangement is associated with each gas inlet valve. A control contour for an idle range is similar to a control contour for a full-load range. A control contour for a part-load range of a gas inlet valve of a shut-off cylinder comprises a section different to a control contour for a part-load range of the gas inlet valve of a remaining cylinder.
