  2. 21. The Role of Plug-in Hybrid Electric Vehicles in Electrifying Personal Transport - Analysis of empirical data from North America

    Author : Ahmet Mandev; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; eVMT; utility factor; charging behavior; fuel consumption; eVKT; greenhouse gas GHG emissions; PHEV Plug-in hybrid electric vehicle ;

    Abstract : Plug-in hybrid electric vehicles (PHEV) can help reduce the greenhouse gas emissions in the transport sector, combined with the decarbonization of the electricity sector, and play an important role in electrifying personal transport. This thesis uses empirical data from North America to investigate the role of PHEVs in electrifying personal transport, with a focus on the household context and charging behavior. READ MORE

  5. 23. Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressor; Air-motor; Pneuamtc; Pneumatic-hybrid; VVT; Valve; regenerative; Hybrid; Air;

    Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. READ MORE

  6. 24. Drag Reduction by means of Active Flow Control Applied on a Generic Truck A-pillar: a Numerical and Experimental Study

    Author : Guglielmo Minelli; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PANS; Large Eddy Simulation; Wind Tunnel.; Bluff Body Flow; Modal Decomposition; Experiments; Vehicle Aerodynamic; POD; Active Flow Control; LES; Partially Averaged Navier Stokes; AFC;

    Abstract : The overall goal of this thesis is to isolate and control the flow mechanism characterizing the flow separation occurring at the A-pillar of a truck. The study aims to gain knowledge of the flow physics of the separation mechanism, and to eventually suppress the afore mentioned separation by means of an Active Flow Control. READ MORE
