Abstract
An arrangement and process for displacing the normally static, fixed rotational shifting speed of an internal-combustion engine in which the timing periods are changed in the form of a valve crossover between the intake valve and the exhaust valve, as a function of the dynamics of the acceleration operation, by a dynamics-dependent rotational differential speed. As a result, the process minimizes the mismatching between the rotational speed of the internal-combustion engine and the possible torque which occurs as a result of a time interval required for influencing the timing periods.
