Fuel consumption and CO2 emission analysis of hybrid and conventional vehicles in urban driving conditions.

Hybrid vehicles are a good solution for a smooth transition towards electromobility. The aim of this paper is to examine the relationship between route parameters and fuel consumption and emissions of harmful exhaust components of vehicles with a conventional and hybrid drive system. As a result of simulation tests, values for fuel consumption and CO₂ emissions for HEV and ICEV vehicles were obtained in 28 trips in urban conditions. The average fuel consumption achieved by the hybrid was 53% lower than that of a conventional vehicle. When analysing the average value of CO₂ emissions, the hybrid showed a 54% lower value than a conventional vehicle. Using statistical methods, the relationship between the route parameters and the operational parameters of the vehicle was determined. It has been shown that the route parameters strongly correlate with the fuel consumption and CO₂ emissions of a conventional vehicle. In the case of hybrid vehicles, there was a weaker relationship between these parameters. [ABSTRACT FROM AUTHOR]
