Comparison of Environmental Impact Between Hybrid Electric Vehicles: Analysis of Pollutant Emissions in Real Driving Emissions Test

This article conducts a comparative analysis of emission factors from three vehicle types (sedan, crossover, SUV) during a Real Driving Emissions (RDE) test, adhering to Euro 6 norms for accuracy. Hybrid electric vehicles (HEVs), combining internal combustion engines with electric propulsion, are examined in real-time driving conditions in a high-altitude city. Data collection involves PID signals, pollutant gas measurements, and GPS data, analyzed using engineering software and statistical methods. The study identifies that aggressive driving behaviors and acceleration phases notably impact CO₂ emissions, particularly on motorways. These findings underscore the role of driving style in influencing environmental emissions, highlighting the potential of HEVs to reduce carbon footprint across urban and highway scenarios.
