  2. 1. Embedded Systems and FPGAs for Implementation of Control Oriented Models, Applied to Combustion Engines

    Author : Carl Wilhelmsson; Förbränningsmotorer; []
    Keywords : NOx; NO; Nitrogen Oxides; Emissions; Air pollution; Algorithms; Physical model; Mathematical model; FPGA; Field Programmable Gate Arrays; Embedded Systems; Micro-controllers; Engine; Diesel Engine; Internal Combustion Engine; Combustion Control; Engine Control.;

    Abstract : Performance demands put on combustion engines are ever increasing, e.g. demands on emissions and fuel consumption. The increased demands together with new combustion concepts increase the need for feedback engine and combustion control. READ MORE

  4. 2. Experimental Investigations of Combustion Chamber Heat Transfer in a Light-Duty Diesel Engine

    Author : Jessica Dahlström; Förbränningsmotorer; []
    Keywords : internal combustion engines; heat transfer; diesel engine; Diesel combustion; combustion chamber geometry; piston geometry; spray parameters;

    Abstract : This work concerned experimental studies of heat transfer in a light-duty diesel engine. Combustion is affected by several parameters, such as pressure, engine speed, mass of injected fuel and in-cylinder gas flow. These parameters are in turn affected by the combustion chamber geometry and fuel spray characteristics. READ MORE

  5. 3. Torque based combustion property estimation and control for diesel engines

    Author : Mikael Thor; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  6. 4. Low Temperature Combustion in a Heavy Duty Diesel Engine

    Author : Malin Ehleskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LIVC; heavy duty; VVA; Diesel engine; Combustion; soot; EIVC; NOx; LTC;

    Abstract : In recent years, there have been major efforts to reduce engine emissions and fuel consumption. The studies described in this thesis were conducted with the aim of identifying methods for reducing harmful engine-out emissions of soot and nitrogen oxides (NOx) under high load without increasing fuel consumption.
