   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

   Sammanfattning : The topic of the thesis is control of Homogeneous Charge Compression Ignition (HCCI) engine dynamics. HCCI offers a potential to combine high efficiency with very low emissions. In order to fulfill the potential benefits, closed-loop control is needed. LÄS MER

5. 4. Control Strategy for Energy Efficient Fluid Power Actuators : Utilizing Individual Metering

   Författare :Björn Eriksson; Jan-Olov Palmberg; Jonas Larsson; Jochen Pohl; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; mode switch; energy efficient; independent metering; split spool; poppet; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : This thesis presents a solution enabling lower losses in hydraulic actuator systems. A mobile fluid power system often contains several different actuators supplied with a single load sensing pump. One of the main advantages is the need of only one system pump. This makes the fluid power system compact and cost-effective. LÄS MER

7. 5. The Performance of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management

   Författare :Jari Hyvönen; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; framdrivningssystem; Variable Compression Ratio; Homogeneous Charge Compression Ignition VCR; termodynamik; Motors and propulsion systems; Termisk teknik; applied thermodynamics; Thermal engineering; Cylinder-to-cylinder; Turbocharging; Multi cylinder; Cylinder balancing; Thermal Management; HCCI;

   Sammanfattning : The prime mover in the world today is the Internal Combustion (IC) engine. The development and improvement of the internal combustion engines since Nicolaus August Otto and Rudolf Diesel has continued until today and will continue long into the future. No major competitor to the IC engine has yet emerged. LÄS MER
