2. 1. Thermodynamic Simulation of HCCI Engine Systems

   Author : Olof Erlandsson; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HAM; Turbine; Compressor; Turbocharger; Engine; Modeling; HCCI; Simulation; Motors and propulsion systems; Motorer; framdrivningssystem;

   Abstract : This thesis focuses on engine system simulation using thermodynamics and chemical kinetic models to investigate the performance and efficiency of Homogeneous Charge Compression Ignition (HCCI) engines for stationary applications. It includes the development of software as well as models for engine, turbocharger, intercooler, inlet and exhaust manifolds, wastegate valve, inlet air humidifier, inlet air heater and more.

4. 2. Model-Based Diesel Engine Management System Optimization - A Strategy for Transient Engine Operation

   Author : Markus Grahn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engine management system; Modeling; Engine control; Diesel engine; Fuel Consumption; Optimization; Emissions; Calibration; Simulation;

   Abstract : To meet increasingly strict emission legislation and stronger demands on fuel consumption, typical passenger car diesel engines become increasingly complex with more and more controllable systems added. These added systems open up for the possibility to operate the engine at more efficient conditions, but it also becomes more challenging to optimize the settings in the engine management system.
