  4. 2. 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

  5. 3. Reducing Diesel Engine Emissions - An Experimental Investigation

    Author : Arjan Helmantel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical methods; Soot; Diesel; Emissions; HCCI;

    Abstract : In the recent past, the Diesel engine has been improved considerably in the areas ofperformance, fuel efficiency and exhaust emissions. In Europe, these improvements haveresulted in a strong increase in the sales of passenger cars equipped with a Diesel engine. READ MORE

  6. 4. 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.

  7. 5. 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
