  1. 16. Gasoline Partially Premixed Combustion - An Advanced Internal Combustion Engine Concept Aimed to High Efficiency, Low Emissions and Low Acoustic Noise in the Whole Load Range

    Author : Vittorio Manente; Lund University.; Lunds universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Environmental concerns such as global warming, the surge of crude oil prices and more stringent emission regulations are demanding the development of internal combustion engines that are highly efficient and low polluting. With classical internal combustion engine concepts such as diesel compression ignition and gasoline spark ignition engines, a trade-off exists between local and global emissions i. READ MORE

  2. 17. On Reduction of Nitrogen Oxides in Heavy-Duty Engines : with NOx Model Feedback, PPC and SNCR

    University dissertation from Department of Energy Sciences, Lund University

    Author : Kenan Muric; Lund University.; Lunds universitet.; [2018-10-03]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aftertreatment; emissions; Engine simulation; engine modeling; SNCR; PPC Engine;

    Abstract : European emission legislation has in recent years put a strict limit on NOx emissionsfrom heavy-duty truck engines. EGR and selective catalytic reduction are the two mostcommon technologies applied in a modern heavy-duty diesel engine to fulfill the legislation. READ MORE

  3. 18. Large Eddy Simulation of Turbulent Combustion in PPC and Diesel Engines

    University dissertation from Department of Energy Sciences, Lund University

    Author : Rickard Solsjö; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; large eddy simulation LES ; turbulent spray combustion; Lagrangian particle tracking LPT ; diesel engines; partially premixed combustion PPC engines.;

    Abstract : This thesis deals with large eddy simulations (LES) of turbulent combustion processes in direct injection internal combustion (IC) engines. Modeling of direct injection IC engine combustion involves modeling of turbulent spray/gas two-phase flow, modeling of chemical reactions of large hydrocarbon fuels and coupling of chemistry with turbulent flows.

  4. 19. A numerical study of mixing phenomena and reaction front propagation in partially premixed combustion engines

    University dissertation from Department of Energy Sciences, Lund University

    Author : Christian Ibron; Lund University.; Lunds universitet.; [2019-11-18]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD simulation; förbränning; antändning;

    Abstract : This work treats the modelling of PPC engine combustion through 3D computational fluid dynamics. In order to develop a cost-effective CFD model for the design and performance analysis of PPC engines it is important to first understand the multiple modes of combustion in PPC engines, e.g. READ MORE

  5. 20. Model Predictive Control (MPC) of an Advanced Multi-Cylinder Engine for Transient Operations

    University dissertation from Department of Energy Sciences, Lund University
