  1. 16. Modeling and control of actuators and co-surge in turbocharged engines

    Författare :Andreas Thomasson; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The torque response of the engine is important for the driving experience of a vehicle. In spark ignited engines, torque is proportional to the air flow into the cylinders. Controlling torque therefore implies controlling air flow. LÄS MER

  3. 17. Experimental Studies of Advanced Ignition Systems for Lean Burn Natural Gas Engines

    Författare :Jessica Dahlström; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ignition system; spark energy; internal combustion engine; engine; spark ignition; natural gas;

    Sammanfattning : One of the greatest challenges for the transport sector today is reducing its environmental impact. This applies especially to the emission aspects, much due to increasingly stringent emissions legislations. LÄS MER

  4. 18. A DAE Formulation for Multi-Zone Thermodynamic Models and its Application to CVCP Engines

    Författare :Per Öberg; Lars Eriksson; Richard Stobart; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In the automotive area there are ever increasing demands from legislators and customers on low emissions and good fuel economy. In the process of developing and investigating new technologies, that can meet these demands, modeling and simulation have become important as standard engineering tools. LÄS MER

  5. 19. Theoretical and Experimental Studies of the Formation of Ionized Gases in Spark Ignition Engines

    Författare :Raymond Reinmann; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermal Ionization; Calorimetry; Interferometry; Spark Ignition Engine; Current and Voltage Measurements; Engine Control.; fluid dynamics; Gases; plasmas; Gaser; plasma; fluiddynamik; Breakdown; Arc; Glow; Flame Ionization; Chemi-Ionization; Spark; Townsend; Fysicumarkivet A:1998:Reinmann;

    Sammanfattning : The processes that govern the formation, existence and consumption of ions in gases have been studied both experimentally and theoretically. The aim of the work is targeted at increasing the understanding of these phenomena in the working gases inside an engine. LÄS MER

  7. 20. Single-Zone Cylinder Pressure Modeling and Estimation for Heat Release Analysis of SI Engines

    Författare :Markus Klein; Lars Eriksson; Lars Nielsen; Per Tunstål; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heat release; parameter estimation; prior knowledge; regularization; specific heat ratio; compression ratio; Systems engineering; Systemteknik;

    Sammanfattning : Cylinder pressure modeling and heat release analysis are today important and standard tools for engineers and researchers, when developing and tuning new engines. Being able to accurately model and extract information from the cylinder pressure is important for the interpretation and validity of the result. LÄS MER
