1. Method for performing tests on an internal combustion engine or a structure which is associated with the engine by measuring output parameter values on at least one output shaft (3LF, 3RF) which is connected to the engine, characterized byproducing a representation of variations in said output parameter values during operation of the engine,said representation of variations in said output parameter values during operation of the engine being produced during one engine cycle,evaluating the representation for determining an operating parameter value for the engine or the structure, wherein the said test is performed by measuring the said output parameter values after a transmission, andthe measuring of the output parameter values after the transmission being a measuring of the output parameter values on at least one wheel shaft (3LF, 3RF) of a vehicle.
