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

   Författare :Malin Alriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low soot; low NOx; low temperature combustion; emissions; diesel combustion;

   Sammanfattning : 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).

3. 2. Turbo Charged Low Temperature Combustion - Experiments, Modeling and Control

   Författare :Hans Aulin; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; PPC; CAI; NVO; low temperature combustion; torductor; ion current; control; modeling; combustion feedback; sensors;

   Sammanfattning : Both the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. LÄS MER

4. 3. Pulsating Combustion - Combustion Characteristics and Reduction of Emissions

   Författare :Annika Lindholm; Förbränningsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exhaust gas recirculation; NOx; Heat Release; Combustion related radicals; Laser based measurements; Pulsating Combustion; Unsteday Flow; Emissions; Combustion; Energy research; Energiforskning;

   Sammanfattning : In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion.

5. 4. Low Temperature Waste Heat Recovery in Internal Combustion Engines

   Författare :Vikram Singh; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low Temperature Waste Heat Recovery; Rankine cycle; Coolant Temperature; Working Fluids;

   Sammanfattning : Over the past few decades, the automotive industry has increasingly looked towards increasing the efficiency of the internal combustion engine to meet more stringent emission norms and as a measure to meet demands for improved air quality in cities. One method to improve the internal combustion engine efficiency is to recover some of the energy lost to the coolant and the exhaust using a secondary thermodynamic cycle such as an Organic Rankine Cycle.

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

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

   Sammanfattning : 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.
