This chapter reviews the cycles used for the certification of non-road engines/vehicles in the world, which are all of the engine-dynamometer type. A distinction is made with respect to whether the cycles are steady-state or transient. For the former case, standard ISO 8178 describes most of the relevant procedures; for the latter, the non-road transient cycle, NRTC, is the applicable test. Historical review, 2D and 3D frequency diagrams and comparative results are presented for all non-road steady-state and transient cycles developed over the years, combined with results from actual engines operation.
