Gaseous Emissions from Light-Duty Vehicles: Moving from NEDC to the New WLTP Test Procedure

Environmental Science & Technology, 2015
The Worldwide Harmonized Light Duty Test Procedure (WLTP), recently issued as GTR15 by UNECE-WP29, is designed to check the pollutant emission compliance of Light Duty Vehicles (LDVs) around the world and to establish the reference vehicle fuel consumption and CO2 performance. In the course of the development of WLTP, the Joint Research Center (JRC) of

Energy Consumption Optimization for an Electric Delivery Vehicle

Energies
For nearly two centuries, electric drives have been used in transportation. Nevertheless, they were not always favored by designers. The century-long dominance of heat engines led to the disregard of numerous challenges associated with the operation of ...
