2. 1. Computer Modeling of HCCI Combustion

   Author : Roy Ogink; Chalmers tekniska högskola; []
   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

4. 2. 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

5. 3. Modeling of Diesel Fuel Spray Formation and Combustion in OpenFOAM

   Author : Anne Kösters; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Break-up; OpenFOAM; PaSR; CFD; Diesel; VRFM; VSB2; Spray;

   Abstract : The formation, ignition, and combustion of fuel sprays are highly complex processes and the available models have various shortcomings. The development and application of multidimensional CFD models, that describe the different phenomena have rapidly increased through the use of commercial and public software (e.g. READ MORE

6. 4. Torque based estimation of diesel engine combustion phasing

   Author : Mikael Thor; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion modeling; Diesel engines; Crankshaft torque measurements; Combustion phasing control; Combustion phasing estimation;

   Abstract : Demands on increased efficiency and reduced emission levels introduce new challenges for the design of modern diesel engines. In order to fulfill these demands, diesel engines of today are becoming more and more complex. This escalating complexity not only applies to the engine itself, but also to its control system.
