  2. 1. DME and the Heavy Duty Diesel Engine

    Author : Henrik Salsing; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; diesel engine; Dimethyl Ether; fuel injection system; DME;

    Abstract : Increasing awareness of adverse anthropogenic environmental effects, such as the effectsof combusting fossil fuels on atmospheric carbon dioxide concentrations, and thatcombustion-related emissions from the transportation sector are going to approachsustainable levels in the near future has led to increased interest in fuels from renewablesources. These fuels offer possibilities to diversify the feedstocks that can be used forfuel production, as well as to reduce fossil carbon dioxide emissions, thereby reducingour dependence on a very limited range of sources.

  4. 2. Particulate Emissions Associated with Diesel Engine Oil Consumption

    Author : Petter Tornehed; Ulf Olofsson; Gordon E. Andrews; KTH; []
    Keywords : Lubrication oil; Particulate emission; Particulate matter PM ; Oil consumption; Diesel engine; Mechanical engineering; Maskinteknik;

    Abstract : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. READ MORE

  5. 3. Low Temperature Combustion in a Heavy Duty Diesel Engine

    Author : Malin Ehleskog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LIVC; heavy duty; VVA; Diesel engine; Combustion; soot; EIVC; NOx; LTC;

    Abstract : In recent years, there have been major efforts to reduce engine emissions and fuel consumption. The studies described in this thesis were conducted with the aim of identifying methods for reducing harmful engine-out emissions of soot and nitrogen oxides (NOx) under high load without increasing fuel consumption.

  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
