摘要：A method of and an apparatus for determining the engine power of anautomotive vehicle on a roller dynamometer, the rollers of which can be braked with aconstant brake poower. In accordance with the invention, in a first measuring operationthe net power of the engine acting on the vehicle wheels is determined by sensing thebraking power acting on the dynamometer rollers. In a second measuring operation, theslowing-down time is measured within which the speed has decreased from a
predetermined value to a second preselected value with unbraked dynamometer rollers.In a third measuring operation the dynamometer rollers are braked with a consant brakepower and the slowing-down time is measured within which the speed has decreasedfrom the initial value to the preset final value. Thereafter, the internal power loss of theautomotive vehicle is calculated. The gross power of the vehicle engine may be
determined by adding the calculated power loss to the previously measured net power.
