  1. 1. Optical Diagnostics of Gasoline Compression Ignition : HCCI-PPC-Diffusion Combustion

    University dissertation from Department of Energy Sciences, Lund University

    Author : Marcus Lundgren; Lund University.; Lunds universitet.; [2017-05-08]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical engine; LTC; HCCI; PPC; Gasoline; High load;

    Abstract : Access to clean and affordable energy is one of the cornerstones of the world's society. Since the introduction of the internal combustion engine, diesel engines have become widely used for transportation in the commercial sector. READ MORE

  2. 2. Alternative Combustion Strategies for Gasoline Engines

    University dissertation from Department of Energy Sciences, Lund University

    Author : Daniel Dahl; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; engines; SI; SGDI; CAI; HCCI; Otto; lean burn; gasoline; combustion; fuel consumption;

    Abstract : Due to increasingly strict legislative demands and customer concerns regarding CO2emissions, there is a need to develop and implement new combustion strategies forgasoline (Otto) engines. In attempts to meet this need, most attention is focusing onthe low load/speed range where the classic spark ignition strategy (SI) has poorefficiency, mainly due to the throttling of the intake air causing pumping losses.

  3. 3. 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; [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

  4. 4. Computer Modeling of HCCI Combustion

    University dissertation from Tryckeriet i E-huset, Lunds universitet

    Author : Roy Ogink; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; detailed-chemistry; surrogate fuel; homogeneous charge compression ignition; internal combustion engines; modeling; HCCI; gasoline; auto-ignition; combustion;

    Abstract : During the last decade an alternative to conventional internal combustion engines, i.e. spark-ignited and Diesel engines, has been under investigation by an ever-increasing number of research groups. READ MORE

  5. 5. Data-Rich Multivariable Control of Heavy-Duty Engines

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Maria Henningsson; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariable Control; Model Predictive Control; LQG Control; Virtual Sensing; System Identification; Diesel engines; HCCI engines; Dual-Fuel Combustion; Cylinder Pressure Sensors;

    Abstract : The combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. READ MORE
