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

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Sammanfattning : 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. LÄS MER

  4. 3. Verkningsgrad hos elbilars växellåda

    Kandidat-uppsats, KTH/Maskinkonstruktion (Avd.); KTH/Maskinkonstruktion (Inst.)

    Författare :Martin Gregorsson; Anton Pihl; [2021]
    Nyckelord :Efficiency matrix; Romax; WLTP; Romax; Verkningsgradsmatris; WLTP;

    Sammanfattning : I denna rapport har verkningsgraden och förluster för elbilars växellådor analyserats. Med hjälp av en programvara för beräkning och analys av växellådor (Romax) skapades en verkningsgradsmatris för en elbils växellåda. LÄS MER

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

    Master-uppsats, KTH/Fordonsdynamik

    Författare :David Akner; [2019]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Dennis Åberg Skender; [2017]
    Nyckelord :modelling; test bench; road load; simulation; test rig;

    Sammanfattning : 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. LÄS MER
