An impact assessment of functional systems in vehicles on CO2 emissions and fuel consumption

The number of facilities for a driver increasing the travel comfort in a PC vehicle is constantly increasing. Most of them are powered by electricity generated at a cost of additional engine load. Power is received directly from the crankshaft by an alternator or air conditioning compressor, which negatively affects fuel consumption. This paper presents the results of CO2 emission testing in actual traffic conditions for vehicles with on and off functional systems responsible for driving comfort. In addition, an assessment of fuel consumption calculated using the carbon balance method was performed. Measurements were made for cold start and preheated combustion unit the research used the latest PEMS mobile apparatus.
