  4. 2. Spray and Spray Combustion Characteristics of Diesel-Ethanol Fuel Blends

    Author : Chengjun Du; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; spray images; Diesel-ethanol blends;

    Abstract : In Diesel engines, the quality of fuel atomization and fuel-air mixing inside the cylinder have important effects on the combustion process, and therefore strongly related to the fuel efficiency and emission formation. To understand how the injected fuel mixes with air and combustion processes in a Diesel engine, fundamental spray experiments can be carried out in a constant chamber under different engine-like conditions.

  5. 3. A DAE Formulation for Multi-Zone Thermodynamic Models and its Application to CVCP Engines

    Author : Per Öberg; Lars Eriksson; Richard Stobart; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In the automotive area there are ever increasing demands from legislators and customers on low emissions and good fuel economy. In the process of developing and investigating new technologies, that can meet these demands, modeling and simulation have become important as standard engineering tools. READ MORE

  6. 4. Vibration based diagnostics for analysis of combustion properties and noise emissions of IC engines

    Author : Grover Zurita Villarroel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : The major challenge in engine diagnostics, monitoring and optimisation is to maintain competitive fuel economy, refinement and specific power while at the same time keeping noise and exhaust emissions at acceptable levels. This requires development and integration of fuel delivery, combustion and after-treatment systems. READ MORE
