1. 1. Diesel Engine Modeling for Engine Management System Development

   Författare :Markus Grahn; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engine control; Diesel engines; Engine management system; Emissions; Simulation; Optimization; Modeling;

   Sammanfattning : Due to increasingly strict emission legislation and stronger demands on fuel consumption, typical passenger car diesel engines become increasingly complex with more and more controllable systems added. These added systems open up for the possibility to operate the engine at more efficient conditions, but it also becomes more challenging to optimize the settings in the engine management system.

   Sammanfattning : To meet increasingly strict emission legislation and stronger demands on fuel consumption, typical passenger car diesel engines become increasingly complex with more and more controllable systems added. These added systems open up for the possibility to operate the engine at more efficient conditions, but it also becomes more challenging to optimize the settings in the engine management system.

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

   Författare :Carl Wilhelmsson; Förbränningsmotorer; []
   Nyckelord :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.;

   Sammanfattning : 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. LÄS MER

7. 5. Prediction of engine component loads using previous measurements

   Författare :Pär Mikaelsson Elmén; Mårten Olsson; Jan-Olov Aidanpää; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine; engine block vibration; engine block twist; engine block bending; vibration measurement; vibration estimation; rigid body vibrations; assumed modes; bending modes; torsion modes; system modification; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Internal combustion engines are used in many applications. The same engine type may have different components mounted to it depending upon its use. These engine mounted components need to be designed against fatigue in order to withstand the engine vibrations. Measured engine vibrations are commonly used as input data for fatigue estimation.
