This chapter summarizes the most important features of the driving/engine cycles test procedure in the laboratory. A brief discussion of the type approval process is first conducted, followed by dynamometer fundamentals, analysis of the road-load equation and description of the coast-down procedure. The main part of the chapter is devoted to the exhaust emissions measurement using the constant volume sampling system, providing description of the facility as well as the basic equations for steady-state and transient testing during both vehicle and engine certification. Emphasis is placed on the procedures/equations valid in the European Union through UNECE regulations, which are also applicable in many other areas in the world; certain differentiations valid in the United States are discussed.
