  1. 1. Refinement and Investigation of Instruments for Emission Screening of Passenger Cars

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Marcus Ruderer; Signe Stéen; [2022]
    Keywords : Emission Screening; Real Driving Emissions; Light-Duty Vehicles; PEMS; SEMS; Emissionskontroll; RDE; Lätta Fordon; PEMS; SEMS;

    Abstract : A Portable Emissions Measurement System (PEMS) is widely used for analysing the emissions of a vehicle. However, the PEMS is quite cumbersome and time-consuming to use for vehicle testing. This thesis investigates the possibilities of a Smart Emissions Measurement System (SEMS) and how it correlates to the more advanced PEMS. READ MORE

  3. 2. Permanent magnet synchronous machine using ferrite vs rare earth magnets : how do they compare?

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nikhil Manakshya; [2021]
    Keywords : Vehicle requirement; drive cycle; ferrite magnet; demagnetisation; environmental impact.; Fordonsbehov; körcykel; ferritmagnet; avmagnetisering; miljöpåverkan.;

    Abstract : Permanent magnet synchronous machines (PMSM are considered as viable options for automotive and traction applications. Rare earth magnets such as Neodymium Iron Boron (NdFeB is the most common choice in the PMSM for electric vehicles to achieve high power density machines. READ MORE

  4. 3. A method to generate drive cycles from operational data

    University essay from KTH/Fordonsdynamik

    Author : David Akner; [2019]
    Keywords : ;

    Abstract : This thesis investigates the possibility to develop a method to generate drive cycles for heavy duty vehicles for Scania’s customers. A representative drive cycle is important to simulate realistic driving of vehicles. READ MORE

  5. 4. Modelling of Test Bench for Road Load Simulation

    University essay from Linköpings universitet/Reglerteknik

    Author : Dennis Åberg Skender; [2017]
    Keywords : modelling; test bench; road load; simulation; test rig;

    Abstract : Warehouse forklifts are often powered by batteries. By using a test bench where the forklift can be driven in a certain driving-cycle, the battery capacity can be tested. To obtain the same speed curve on the test bench as a forklift obtains when driving on a real road, the test bench must be able to simulate road load. READ MORE

  6. 5. Analysis of dropbox assisted hydraulic traction

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Zhen LI; [2017]
    Keywords : Accumulator; Brake Energy Recovery; Drive; Hydraulics; Truck; Ackumulator; Drivlina; Hydraulik; Lastbil; Regenerativ bromsning;

    Abstract : The research looks at the advantages and disadvantages of a hydraulic auxiliary drive (HAD) system which is installed on a 25 meter long timber transport vehicle. The purpose is to investigate the performance with regard to energy, economy and environment of the system due to the added components, the hydraulic accumulators. READ MORE
