2. 1. Model-Based Diesel Engine Management System Optimization - A Strategy for Transient Engine Operation

   Author : Markus Grahn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engine management system; Modeling; Engine control; Diesel engine; Fuel Consumption; Optimization; Emissions; Calibration; Simulation;

   Abstract : 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. 3. Towards active engine mounting systems for commercial vehicles: modeling and analysis

   Author : Hoda Yarmohamadi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear dynamic stiffness and damping; Actuators; Computational model; Conventional engine mount; Vibration isolation; Adaptronic mounting system; Model errors tolerance; Commercial vehicles;

   Abstract : The vehicle engine mounting system, which consists of several mounts connecting the engine to the vehicle structure, not only supports the weight of the engine but also isolates the noise, vibration and the transmitted forces to the vehicle structure. At present conventional elastomeric mounts are widely used in engine mounting systems for commercial vehicles. READ MORE

6. 4. CFD-based Analysis of Combustion Processes in a Free-Piston Diesel Engine

   Author : Miriam Bergman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical kinetics; Diesel; homogeneous charge compression ignition HCCI ; free-piston; equivalence ratio vs. temperature maps; computational fluid dynamics CFD ; surrogate fuel;

   Abstract : The Free Piston Engine (FPE) which is capable of operating in a variable compression ratio mode, allows flexible auto-ignition control on a cycle-to-cycle basis without any hardware modifications. In this study combustion processes in an FPE were examined using the KIVA-3V CFD code with detailed chemical kinetics (305 reactions among 70 species) of a Diesel surrogate fuel incorporated.
