Comparison study of fuel consumption and emissions of HEVs and conventional vehicle in Iraq using real-world cycle(Article)

Abstract

This paper aims to share awareness for adopting the technology of hybrid electric vehicles (HEVs) and to introduce their benefits in terms of fuel consumption and pollutant emissions. The economic and environmental metrics are the main concerned perspectives when comparing the hybrid electric vehicles (HEVs) to the equivalent conventional vehicle. Furthermore, for investigating the system power effect on fuel economy and emissions, two models of the parallel architecture were structured and separately simulated, and likewise for the series architecture. The comparison is based on performance analyses under real-world driving patterns that emulate the studied route conditions. A commonly-used data logger was utilized to gather driving data necessary for creating the real-world driving cycle. Advanced vehicle simulator, is considered in this work to perform the simulation process, and to obtain all the involved performance predictions. Significant fuel consumption and emissions reductions are predicted by the electrified vehicles over the conventional counterpart; the highest fuel consumption reduction (54.7%) was achieved by the series HEV2, whereas the lowest (27.6%) was achieved by the parallel HEV1. The best emissions reduction in terms of hydrocarbon (HC), carbon monoxide (CO), and nitrogen oxides (NOx) emission was attained by the series HEV1 and was documented as; 80.8%, 74.8%, and 77.7%, respectively. The smallest reduction was attained by the parallel HEV1 as; 40.5%, 43.7%, and 26% for HC, CO, and NOx. respectively. The results indicate that meaningful improvements in fuel economy and emissions are achievable if the HEV is recruited on such a road in the city of Baqubah. © 2020 Zibeline International Publishing Sdn.
