  1. 1. Calculation of neutron scattering libraries for liquid ortho-deuterium and hydrogen deuteride

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Alexander Huusko; [2022]
    Keywords : PIMD; NJOY; HD; D2; HighNESS; ESS; RPMD; TSL; Physics and Astronomy;

    Abstract : The European Spallation Source (ESS) has launched a project called HighNESS, with the task of investigating the potential of adding a second moderator system to the facility, with ortho-deuterium (o-D2) being the main material of interest. Another moderator material which could be of interest is hydrogen deuteride (HD). READ MORE

  3. 2. Stochastic Knock Control for Improved Efficiency

    University essay from Linköpings universitet/Fordonssystem

    Author : Jonas Vedin; Robert Widén; [2019]
    Keywords : Knock control; Stochastic knock control; Knock simulation;

    Abstract : Increasing the efficiency and performance of internal combustion engines is always of interest in the automotive industry. One limiting factor to achieve this in gasoline combustion engines is the ignition timing which can not always be set where optimal ignition efficiency and performance is obtained. READ MORE

  4. 3. Knock model evaluation - Gas engine

    University essay from KTH/Förbränningsmotorteknik

    Author : Nishchay Sharma; [2018]
    Keywords : Knocking; Spark-Ignited; Internal Combustion Engine; Spark-Knock; Empirical Correlation Models; BOOST; Combustion Phasing; Spark-advance; Combustion Duration; Knock Prediction Parameter.; Knack; Otto-förbränning; Förbränningsmotor; Empiriska korrelationsmodeller; BOOST; Förbränningsfasning; Tändvinkel; Förbränningsduration; Knackprediktering;

    Abstract : Knack i en förbränningsmotor är en typ av onormal förbränning. Det är ett komplicerat fenomen som beror på flera fysiska faktorer och resulterar i högfrekventa tryckoscillationer inuti förbränningskammaren. Dessa oscillationer kan skada motorn och fenomenet hämmar motorns effektivitet. READ MORE

  5. 4. Estimation of Engine Gas Temperatures During Pressure Transients

    University essay from Linköpings universitet/Fordonssystem

    Author : Marcus Wallson; [2018]
    Keywords : ;

    Abstract : Coming stringent regulatory emissions requirements with Real Driving Emissions testing amplifies the need for efficient engine control at all driving scenarios. This thesis has investigated the air-flow transients that appears when changing the throttle position very fast, such as at a stop sign. READ MORE

  6. 5. Knock Model Evaluation – Gas Engine

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Nishchay Sharma; [2018]
    Keywords : Knocking; Spark-Ignited; Internal Combustion Engine; Spark-Knock; Empirical Correlation Models; BOOST; Combustion Phasing; Spark-advance; Combustion Duration; Knock Prediction Parameter.; Knack; Otto-förbränning; Förbränningsmotor; Empiriska korrelationsmodeller; BOOST; Förbränningsfasning; Tändvinkel; Förbränningsduration; Knackprediktering.;

    Abstract : Knocking is a type of abnormal combustion which depends on several physical factors and results in high frequency pressure oscillations inside the combustion chamber of a spark-ignited internal combustion engine (ICE). These oscillations can damage the engine and hamper its efficiency, which is why it is important for automakers to understand the knocking behavior so that it can be avoided during engine operation.
