  1. 1. Optical Diagnostics of Gasoline Compression Ignition : HCCI-PPC-Diffusion Combustion

    University dissertation from Department of Energy Sciences, Lund University

    Author : Marcus Lundgren; Lund University.; Lunds universitet.; [2017-05-08]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical engine; LTC; HCCI; PPC; Gasoline; High load;

    Abstract : Access to clean and affordable energy is one of the cornerstones of the world's society. Since the introduction of the internal combustion engine, diesel engines have become widely used for transportation in the commercial sector. READ MORE

  2. 2. Low Temperature Combustion in a Heavy Duty Diesel Engine

    University dissertation from Department of Energy Sciences, Lund University

    Author : Malin Ehleskog; [2012]
    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.

  3. 3. Direct Numerical Simulations of Low Temperature Combustion in IC Engine Related Conditions

    University dissertation from Department of Energy Sciences, Lund University

    Author : Fan Zhang; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with direct numerical simulation (DNS) of low temperature combustion in internal combustion engine related conditions. In particular, HCCI (homogeneous charge compression ignition), SACI (spark assisted ho-mogeneous charge compression ignition) and PPC (partially premixed charge combustion) were investigated to gain deeper understanding on the details of the combustion process.

  4. 4. Understanding and enhancing translation by parallel text processing

    University dissertation from Linköping : Linköpings universitet

    Author : Magnus Merkel; Linköpings universitet.; Linköpings universitet.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : In recent years the fields of translation studies, natural language processing and corpus linguistics have come to share one object of study, namely parallel text corpora, and more specifically translation corpora. In this thesis it is shown how all three fields can benefit from each other, and, in particular, that a prerequisite for making better translations (whether by humans or with the aid of computer-assisted tools) is to understand features and relationships that exist in a translation corpus.

  5. 5. An Investigation of Low Temperature Combustion Using high Levels of EGR

    University dissertation from Linköping : Linköpings universitet

    Author : Malin Alriksson; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low soot; low NOx; low temperature combustion; emissions; diesel combustion;

    Abstract : The diesel engine offers good fuel economy and generates low carbon dioxide (CO2) emissions, but it is also a source of undesirably high particulate matter (PM) and nitrogen oxide (NOx) emissions, which are subject to increasingly strict legislative limits because of their adverse effects on the environment and human health. Thus, in recent years, several combustion concepts have been developed to meet future legislation requirements, one of which is Low Temperature Combustion (LTC) using high levels of EGR (Exhaust Gas Recycling).
