Effectiveness of the measures for CO2 emission reduction in real world

Abstract

Abstract To reduce the CO2 emission level for the new Corporate Average Fuel Economy regulations, a series of measures are implemented by the manufacturers. Besides the use of hybrid and electric vehicles, efficiencies packages are frequently applied to improve the CO2 emissions of conventional vehicles. Some examples of CO2 reduction measures are: Start&Stop system, eco tires, powertrain thermal management and aerodynamic kits. Usually, they are optimized for the WLTC (Worldwide Harmonized Light Vehicles Test Cycle). The aim of this paper is to assess the influence of these packages in real-world driving cycles. The study is done by means of modelling and simulation, using an industrial modelling and simulation environment (LMS Imagine.Lab AMESim). Two passenger cars from different classes, a compact type and a SUV are used.
