  2. 1. Processes in Optical Diesel Engines - Emissions Formation and Heat Release

    Author : Ulf Aronsson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Engines; Optical Engines; Heat Release; Combustion; Emissions Formation; Mechanical Deformation;

    Abstract : This project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. READ MORE

  4. 2. Optical Diagnostics Applied to Internal Combustion Engines: Catalysis, Sprays and Combustion

    Author : Stina Hemdal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sprays; Optical diagnostics; engines; ; combustion; spray-guided; SGDI; Direct-injection; catalys;

    Abstract : Gasoline direct injection with spray-guided charge formation is one of the most promising concepts to reduce fuel consumption and CO2 emissions of spark ignited engines. The advantages with the system are owing to un-throttled operation and stratification of the injected fuel resulting in a globally lean combustion. READ MORE

  5. 3. Optical Diagnostic Techniques Applied in Practical Combustion Devices and Processes

    Author : Joakim Rosell; Förbränningsfysik; []
    Keywords : Optical diagnostics; LIF; OH; CO; CH2O; CH; Optical Engines; Fysicumarkivet A:2016:Rosell;

    Abstract : Optical measurement techniques have proven to be useful tools for studying combustion-related phenomenon. The fact that the techniques are optical facilitates performing the measurements without impinging upon the measurement object, such as the combustion event that can be involved. READ MORE

  6. 4. Alternative Combustion Strategies for Gasoline Engines

    Author : Daniel Dahl; Chalmers tekniska högskola; []
    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.

  7. 5. Late Cycle Soot Oxidation in Diesel Engines

    Author : Yann Gallo; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soot oxidation; Laser extinction; Optical diagnostics; Diesel engines; Gas sampling; Particulate matter;

    Abstract : Diesel engines are the most common engine technology used in transportation. Its widespread use comes from its inherent high efficiency and its relative low cost. It suffers from pollutant emission issues, however, that need detailed understanding of their origins to meet the strictest current and upcoming emission standards. READ MORE
