1. 1. Torque based estimation of diesel engine combustion phasing

   Författare :Mikael Thor; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion modeling; Diesel engines; Crankshaft torque measurements; Combustion phasing control; Combustion phasing estimation;

   Sammanfattning : Demands on increased efficiency and reduced emission levels introduce new challenges for the design of modern diesel engines. In order to fulfill these demands, diesel engines of today are becoming more and more complex. This escalating complexity not only applies to the engine itself, but also to its control system.

   Sammanfattning : Due to environmental aspects and emission legislations the automotive industry is striving towards more efficient combustion engines. Many engine control systems in production today are based on look-up tables which are calibrated for different operating conditions. LÄS MER

5. 4. 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.
