Real-world fuel economy and emission levels of a typical EURO-IV passenger vehicle

This paper presents the findings of research into real-world emission levels of a typical EURO-IV passenger car in the United Kingdom (UK). Four real-world drive cycles representing typical urban driving in the UK were used for the experiments. The work identified that the real-world emission levels of a EURO-IV vehicle in the UK are significantly higher than the certified legislative emission levels. The present work also identified that tailpipe-out carbon monoxide is the most affected emission specie in a gasoline-powered vehicle for real-world driving conditions.
