  1. 1. Torque based combustion property estimation and control for diesel engines

    Author : Mikael Thor; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Crankshaft torque measurements; Engine control; Combustion modeling; Diesel engines; Closed-loop control; Internal combustion engines; Combustion property estimation; Combustion phasing;

    Abstract : Modern diesel engines are becoming increasingly complex as a result of demands on the reduction of both fuel consumption and emissions. This escalating complexity not only applies to the engine itself, but also to its control system. READ MORE

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

    Author : Stina Hemdal; Chalmers University of Technology; []
    Keywords : ; 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. 5. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines

    Author : Zhenkan Wang; Förbränningsfysik; []
    Keywords : Combustion diagnostics; Laser induced fluorescence LIF ; Ultra-high-speed; Burst-mode laser; Ballistic imaging; Particle imaging velocimetry; Laser Doppler anemometry; Turbulent premixed combustion; Plasma; Internal combustion engine; Partially premixed combustion PPC ; Auto-ignition; OH radical; CH2O formaldehyde ; Fysicumarkivet A:2018:Wang;

    Abstract : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. READ MORE
