【 摘 要 】

The article presents the results of CO2 emission and mileage tests performed in real operating conditions using mobile measuring devices from the PEMS (Portable Emission Measurement System) group. The tests were performed on two different routes, which represented the conditions of urban, extra-urban and motorway driving. The measurements were performed on a working day of the week at similar times, so as to ensure high repeatability of traffic conditions. Two research objects were used in the research. The first was a vehicle with a hybrid drive system, and the other was equipped with a spark-ignition engine with direct petrol injection. Both vehicles adhered to the Euro 5 emissions standard. Based on the obtained results, the operating time share characteristics were determined, both for the ambient conditions and for the drive systems operation. As a result, it was possible to determine the operating time in electric mode of a hybrid drive system and to determine the impact of measurement conditions on obtained CO2 emission and fuel consumption values for both tested vehicles.
