  1. 1. Modeling and Estimation of Long Route EGR Mass Flow in a Turbocharged Gasoline Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : Erik Klasén; [2016]
    Keywords : Long Route Low Pressure LR LP EGR SI Gasoline Spark Ignited Engines Modeling Modelling Mass Flow Estimation;

    Abstract : Due to the continuous work in the automobile industry to reduce the environmental impact, reduce fuel consumption and increase efficiency, new technologies need to be developed and implemented in vehicles. For spark ignited engines, one technology that has received more attention in recent years is long route Exhaust Gas Recirculation (EGR), which means that exhaust gases after the turbine are transported back to the volume before the compressor in the air intake system of the engine.

  3. 2. The potential of increased efficiency and power for a turbocharged PFI-SI engine through variable valve actuation and DEP

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Michael Nilsson; Jim Larsson; [2015]
    Keywords : Technology and Engineering;

    Abstract : New legislation involving emissions from internal combustion engines are pushing the manu-facturers to develop new technology faster than ever before with the amount of greenhouse gases. To meet the standards new concepts need to be developed with lower fuel consumption and emissions. READ MORE

  4. 3. Transient Control of SIDI-Engine with VGT and VVT

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Erik Klingborg; [2012]
    Keywords : ;

    Abstract : Today's development of spark ignited (SI) engines is to a large extent focused on downsizing, i.e where a large naturally aspirated engine is replaced with a smaller turbocharged engine with the same output power. READ MORE

  5. 4. Model-based turbocharger control : A common approach for SI and CI engines

    University essay from Institutionen för systemteknik

    Author : Erik Lindén; David Elofsson; [2011]
    Keywords : modeling; model-based control; non-linear control; turbocharged SI engine; turbocharged CI engine; wastegate; VGT;

    Abstract : In this master’s thesis, a turbine model and a common control structure for theturbocharger for SI and CI-engines is developed. To design the control structure,simulations are done on an existing diesel engine model with VGT. READ MORE

  6. 5. GT-Power Modeling of a 6-Cylinder Natural Gas E>ngine and Investigation of the Possible Performance Improvements by Studying the Miller Cycle

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Lehon Hamarashid; [2008]
    Keywords : Miller Cycle; GT-Power Modeling; Natural Gas Engine; Technology and Engineering;

    Abstract : This master thesis has been conducted at the Division of Combustion Engines under the Department of Energy Sciences, Faculty of Engineering at the Lund University. The purpose of this master thesis project is to create a computer based model of a Natural Gas Engine in order to raise its potential for updating a Volvo bus as well as creating a study of the improvement efficiency of the Miller Cycle.
