Novel approach for connecting real driving emissions to the European vehicle la...
Varella, Roberto A.; Ribau, João; Baptista, Patricia; Sousa, Luís; Duarte, GonçaloVehicle emission certification is evaluated under laboratorial conditions, where vehicles perform a standard driving cycle in controlled conditions leading to several critics, which have resulted in the implementation of the Worldwide harmonized Light Vehicle Test Procedure (WLTP) and the Real Driving Emissions (RDE) testing procedure, as a complementary certification procedure. RDE is still under debate since ...
Analysis of four-stroke, wankel, and microturbine based range extenders for ele...
Ribau, João; Silva, Carla; Brito, F. P.; Martins, JorgeThis paper aims to compare the energy efficiency and CO2 emissions of four different range extender engine solutions deployed in the same baseline series hybrid vehicle, under a combination of driving scenarios aiming to be representative of typical driving instead of standard cycles. Baseline vehicle is roughly based on Chevy VOLT/Opel Ampera. The baseline internal combustion engine is replaced by an overexpan...
