  1. 1. The HCCI Fuel Number - Measuring and Describing Auto-ignition for HCCI Combustion Engines

    University dissertation from Tryckeriet i E-huset, Lunds universitet

    Author : Ida Truedsson; Lund University.; Lunds universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel; Combustion Engines; HCCI; Auto-ignition;

    Abstract : HCCI is an advanced combustion concept, using premixed fuel and air with a diluted charge. This is thermodynamically favorable, leading to high efficiency and therefore lower CO2 emissions. READ MORE

  2. 2. Thermodynamic Simulation of HCCI Engine Systems

    University dissertation from Combustion Engines

    Author : Olof Erlandsson; Lund University.; Lunds universitet.; [2002]
    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.
