2. 1. Efficiency and Mixing Analysis of EGR-Systems for Diesel Engines

   Author : Simon Reifarth; Hans-Erik Ångström; Nils Tillmark; Andreas Cronhjort; José Galindo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EGR; Exergy; mixing; pulsating flow; HP-EGR; LP-EGR; high-pressure EGR; low-pressure EGR;

   Abstract : The reduction of fuel consumption and the reduction of toxic emissions are the main goals of research and development in the area of internal combustion engines. The use of exhaust gas recirculation (EGR) to come further in that direction is today an established method for diesel engines. READ MORE

4. 2. Model Based Optimization of a Complete Diesel Engine/SCR System

   Author : Claes Ericson; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MPC; model based optimization; real time models; model based control; SCR; optimization; EGR;

   Abstract : Achieving upcoming emissions legislation (Euro VI) for heavy trucks is a serious challenge for the manufacturers. Apart from the increasingly strict limits on nitrogen oxides (NOx) and particulate emissions (PM), the limited amount of fossil fuels as well as alarming climate changes simultaneously drives the demand for low CO2 emissions.

   Abstract : Current combustion engines provide excellent performance for vehicle propulsion and power generation. However, recent demands from society ask for higher efficiencies and lower emissions. These requirements are hard to meet with current technology and call for new solutions. READ MORE

6. 4. A Combustion Concept for Future Heavy-Duty Diesel Engines

   Author : Tobias Husberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel combustion; Common rail; Diesel engines; Multiple injections; Combustion concept; Heavy-duty;

   Abstract : The Diesel engine has been intensively developed by manufacturers and researchers since 1892, when it was invented. However, the direction of its development has shifted in recent years.Environmental issues are becoming increasingly important in our society, prompting more efforts to be put into making the engines cleaner.

7. 5. Characterization and Control of Multi-Cylinder Partially Premixed Combustion

   Author : Magnus Lewander; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Efficiency estimation; Closed-loop control; EGR; Diesel engine; Partially Premixed Combustion; Combustion control;

   Abstract : In the last decade diesel combustion has developed in a new direction. Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion concepts is Partially Premixed Combustion (PPC). READ MORE
