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

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

    Abstract : 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. READ MORE

  2. 2. Model Predictive Control (MPC) of an Advanced Multi-Cylinder Engine for Transient Operations

    Author : Lianhao Yin; Institutionen för energivetenskaper; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MPC; Receding horizon sliding mode control; PPC;

    Abstract : The transportation sector is one of the main contributors to greenhouse gas CO2 and emission of toxic gas. In this sector, advanced technologies and innovations to increase engine efficiency is an important research topic. Low-Temperature Combustion (LTC) concepts are effective approaches for high-efficiency engines. READ MORE

  3. 3. Intake air dynamics on a turbocharged SI-engine with wastegate

    Author : Per Andersson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : On turbocharged spark-ignited (SI) engines with wastegate the position of the wastegate changes the exhaust manifold pressure. A secondary effect of this is that the residual gas mass trapped inside the cylinder at exhaust valve closing changes and causes the volumetric efficiency to change. READ MORE

  4. 4. A specific heat ratio model and compression ratio estimation

    Author : Marcus Klein; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Cylinder pressure modeling and heat release analysis are today important and standard tools for engineers and researchers, when developing and tuning new engines. An accurate specific heat ratio model is important for an accurate heat release analysis, since the specific heat ratio couples the systems energy to other thermodynamic quantities. READ MORE

  5. 5. Ion Current and Torque Modeling for Combustion Engine Control

    Author : Ingemar Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Engine control development constantly requires more information about the combustion process, to meet present and future environmental regulations for vehicles. The demand for combustion monitoring and control from enginedevelopers drives the research in several parallel fields of technology to find the best and most cost effective sensor solution for each case.
