EPA's application-specific duty cycles specify a short period of operation in engine speed and load targets over which an engine (on a dynamometer) may be run to simulate the in-use operation of a particular piece of equipment. The nonroad duty cycles found on this page represent the activity of various nonroad engines and equipment, such as agricultural tractors, backhoes, excavators and skid-steer loaders.
