The use of air conditioning systems in passenger cars in Brazil has increased significantly in the last decade. The installation rate increased from 47% in 2006 to about 80% in 2012. Especially for compressors with variable displacement, the measurement of the impact of this equipment on the engine performance and on the fuel consumption represents a challenge to be overcome. It must be considered that the environmental conditions present a great influence on the heat load to be removed from the passenger compartment. This paper describes the development of an experiment at an engine dynamometer bench to simulate the influence of the air conditioning system on the engine parameters. The combustion engine works with the compressor and all the others air conditioning system components assembled.
