  2. 1. 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.

  4. 2. DME Combustion in Heavy Duty Diesel Engines

    Author : Henrik Salsing; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; heavy duty; DME; dimethyl ether; Diesel engine;

    Abstract : Interest in alternative energy and fuels has grown considerably in recent years due to increasing concern about the adverse effects of global warming, the limited sources of non-renewable feedstocks, the insecurity of their supply and associated fluctuations in their prices. However, although there is an urgent, and widely recognized, need to address these issues, selecting suitable candidate feedstocks and fuels is far from straightforward, since numerous factors must be considered when selecting promising candidates for further evaluation and, ultimately, commercial use.

  5. 3. 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.

  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.
