Summary:

So as to fulfill the future requirements regarding fuel consumption and exhaust gas emissions, new technologies have to be adopted in future generations of spark ignition engines. The mechanical fully-variable valve train (MVVT) is one possible technology as BMW has already successfully proven with the Valvetronic-System [1]. At present a large number of such systems is in development. All those systems are alike in terms of their additional variability regarding valve lift and valve opening time by increasing the number of system design units. An increase of the number of design units and the associated increase of the number of the contacts and articulated joints, render such systems softer and dynamically more sensitive than regular types of valve trains, e.g. a roller cam follower or a roller finger follower actuation
