  1. 16. Impact of Pressure Pulsations on Diesel Air Path Control and Compensation Measures

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : NISHANT DHANORE; [2019]
    Keywords : ;

    Abstract : Stricter pollution norms have led to increased efforts to achieve lower emissions. Exhaust Gas Re-circulation (EGR) is a well known measure to reduce NOx internally in the engine. In order to achieve better performance of an engine in terms of emissions it is very essential to control the flow of exhaust gases through EGR valve. READ MORE

  3. 17. Sulfur poisoning and regeneration of copper zeolites for NH3-SCR : Effect of SO2/SO3 ratio

    University essay from Luleå tekniska universitet/Kemiteknik

    Author : Åsa Högström; [2018]
    Keywords : Cu-zeolites; Ammonia-SCR; Sulfur poisoning; Regeneration; Kinetic model;

    Abstract : The road transportation is a big source for the release of NOx emissions. NOx has been confirmed to cause negative affect on the air-quality especially in the urban areas, there are therefore regulations for allowed released amount from vehicles. READ MORE

  4. 18. CFD Investigation of Aerodynamic Drag Reduction for an Unloaded Timber Truck

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Raffaele Colombi; [2018]
    Keywords : CFD; Aerodynamics; Drag Coefficient; Truck;

    Abstract : The road transport industry is facing a strong need for fuel consumption reduction, driven by the necessity of decreasing polluting emissions, such as CO2 and NOX, as well as coping with strict regulations and increasing fuel costs. For road vehicles the aerodynamic drag constitutes a major source of energy consumption, and for this reason improving the aerodynamic performance of the vehicle is an established approach for reducing fuel consumption and greenhouse gases emissions.

  5. 19. Design of Helix-Rotary Evaporator : Concept development, Design and Material selection

    University essay from

    Author : Surafel Tesema; [2018]
    Keywords : Aftertreatment system; SCR; Urea evaporator;

    Abstract : Tougher environmental legislations are a driving force for development of aftertreatment technologies for truck and car exhaust gases. In particular, the emission requirements are high on nitrogen oxides (NOx) and particulate matter. Focus of this thesis work is to develop a component in the exhaust system, a NOx level reduction system. READ MORE

  6. 20. Impact of Engine Dynamics on Optimal Energy Management Strategies for Hybrid Electric Vehicles

    University essay from Linköpings universitet/Fordonssystem

    Author : Andreas Hägglund; Moa Källgren; [2018]
    Keywords : HEV; energy management strategy; EMS; convex optimization; ECOS; model predictive control; MPC; equivalent consumption minimization strategy; ECMS; engine dynamics; NOx;

    Abstract : In recent years, rules and regulations regarding fuel consumption of vehicles and the amount of emissions produced by them are becoming stricter. This has led the automotive industry to develop more advanced solutions to propel vehicles to meet the legal requirements. READ MORE
