LIPP Valvetrain

The valve lift is a key parameter for the achievement of the targeted engine performance. When designing  a valve lift, there are several restrictions, which have to be considered to guarantee the demanded lifetime and rpm-range. In geometrical terms, the design of the valve lift is restricted by the distance between the valves as well as the clearance between valve and piston, whereas on the mechanical side it is important to consider the mechanical stress (contact pressure and the stiffness).

By means of our software LIPP Valvetrain, we design valve lift curves according to your specifications regarding the opening times, lift, ramp length, ramp height, symmetrically or asymmetrically or by the definition of your target-valvelift, while taking into account all given boundary conditions.
