Abstract

This manuscript instrumented two light-duty passenger cars to construct real-world driving cycles for the Baghdad-Basrah highway road in Iraq using a data logger. The recorded data is conducted to obtain typical speed profiles for each vehicle. Each of the recruited vehicles is modelized using Advanced Vehicle Simulator and conducted on the associated created driving cycle to investigate fuel economy and analyze performance. Moreover, to inspect the influence of driving behavior on fuel consumption and emissions, the simulation process is re-implemented by substituting the conducted real-world driving cycle. The analyses are done for the first and second stages of simulation predictions to explore the fuel-penalty of aggressive driving behavior. The analysis for substitution predictions showed that fuel consumption could be reduced by 12.8% due to conducting vehicle under the more consistent real-world driving cycle. However, conducting vehicle under the more aggressive one would increase fuel consumption by 14.6%. The associated emissions change prediction due to the substitution is also achieved and presented.

Highlights

Fuel economy means that a vehicle is traveling a specified distance in a reasonable time and consumes fuel as less as possible
The analysis demonstrated that 94% of vehicles consume higher energy under real-world driving cycles than under UDDS and HWFET cycles [8]
This study aims to investigate the influence of driver behavior on the fuel economy in the first place

Summary

Introduction

Fuel economy means that a vehicle is traveling a specified distance in a reasonable time and consumes fuel as less as possible. The fuel economy depends basically on the engine load, the load demand is influenced by many parameters like; vehicle’s weight, engine’s size, aerodynamic resistance, rolling resistance, and terrains (i.e. uphill, downhill, or flat) [1]. Fuel economy is strongly affected by the engine load which yields the driver pedal press. There are no inclusive standard limits for GHGs in Iraq, but for HC and CO emissions that were reported beaten by a 30% increased concentrations [2]. Test cycles are standard driving cycles that introduce speed and elevation profiles versus time, the standard driving cycles were firstly used to judge the gaseous emissions of tested vehicles. Having useful findings had been proven, the standard driving cycles were utilized to
