1. 16. Empirical Knock Model for Automatic Engine Calibration

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Per Ganestam; [2010]
   Keywords : Technology and Engineering;

   Abstract : Engine knock is an undesired phenomenon in spark ignited internal combustion engines; such as a gasoline engine running the Otto cycle. Knocking originates from abnormal combustions at timings other than those decided by controlled ignition. Individual abnormal combustions of this type is also referred to as auto-ignition. READ MORE

3. 17. Tuning and Validation of an MVEM for a Turbocharged Gasoline Engine

   University essay from Fordonssystem

   Author : Stefan Tuvesson; [2009]
   Keywords : measurements; parameters;

   Abstract : One of the tools that is used when developing an engine control system is the Mean Value Engine Model (MVEM). The thesis examines the possibility of using an MVEM that originally was designed to model a SAAB B235R engine to model the considerably different GM Ecotec LNF engine. READ MORE

4. 18. Analysis of Alternative Fuels in Automotive Powertrains

   University essay from Institutionen för systemteknik

   Author : Andreas Gunnarsson; [2009]
   Keywords : Well-to-wheel analysis; alternative fuel; gasoline; diesel; methanol; ethanol; natural gas; biomethane; synthesis gas; hydrogen; biogas; biodiesel; FT-diesel; DME;

   Abstract : The awareness of the effect emissions have on the environment and climate has risen in the last decades. This has caused strict regulations of greenhouse gas emissions. Greenhouse gases cause global warming which may have devastating environmental effects. Most of the fuels commercially available today are fossil fuels. READ MORE

5. 19. 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.

6. 20. Recognizing Combustion Variability for Control of Gasoline Engine Exhaust Gas Recirculation using Information from the Ion Current

   University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Author : Anna Holub; Jie Liu; [2006]
   Keywords : Internal combustion engines; ion current; exhaust gas recirculation; engine control; neural networks; K-nearest neighbour; combustion variability;

   Abstract : The ion current measured from the spark plug in a spark ignited combustion engine is used as basis for analysis and control of the combustion variability caused by exhaust gas recirculation. Methods for extraction of in-cylinder pressure information from the ion current are analyzed in terms of reliability and processing efficiency. READ MORE
