  1. 21. HCCI Timing Control Using Iterative Feedback Tuning

    L3-uppsats, KTH/Reglerteknik

    Författare :Colette Castell Hernández; [2006]
    Nyckelord :;

    Sammanfattning : The Homogeneous Charge Compression Ignition (HCCI) is an engine which combines some of the characteristics of the Diesel and Otto engines. As a result an engine with a high efficiency and low emissions is constructed. Unfortunately, there is not a direct way to control its start of combustion (SOC). One way to phase the SOC is using valve timings. LÄS MER

  3. 22. Direct-EGR tillämpat på HCCI

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Daniel Ståhl; Freddie Tydal; [2006]
    Nyckelord :;

    Sammanfattning : The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of low NO x, low particulates and high efficiency. Due to its homogeneous charge, where the combustion starts almost simultaneously from a number of points in the combustion chamber, only lean mixtures are possible to burn because of the resulting rapid combustion, which is much faster than the combustion in an SI-engine or a diesel engine.

  4. 23. A stratigraphic study of a coastal section through a Late Weichselian kettle hole basin at Ålabodarna, western Skåne, Sweden

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Jessica Oster; [2004]
    Nyckelord :geography; geology; stratigraphy; Ålabodarna; Skåne; Sweden; Late Weichselian; kettle hole basin; Earth and Environmental Sciences;

    Sammanfattning : Populärvetenskaplig sammanfattning: En undersökning har utförts av sediment avsatta i en liten sjöbassäng som exponerats i kustklinten vid Ålabodarna i västra Skåne. Undersökningen har bidragit med betydelsefull information om vegetationens ankomst till och expansion i området. LÄS MER

  5. 24. Methods for Ionization Current Interpretation to be Used in Ignition Control

    Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska högskolan

    Författare :Lars Eriksson; [1995]
    Nyckelord :Ionization current; pressure peak; spark timing;

    Sammanfattning : It is desirable to measure engine performance for several reasons, e.g. when computing the spark advance setting in spark-ignited (SI) engines. There exists two methods, among others, of measuring the performance, such as measuring the pressure and the ionization current. LÄS MER
